They are practical, productive, and far less fussy than many beginners expect. You do not need a huge vegetable plot, perfect soil, or years of experience to grow them well. In fact, potatoes are often one of the best crops for building confidence because they give visible progress, tolerate ordinary UK conditions reasonably well, and reward even a fairly simple setup with a worthwhile harvest.

That said, potatoes are still easy to misunderstand.

People often think of them as a crop you just put in the ground and come back to later. Sometimes you get away with that. But if you want a better crop, better growth, and fewer setbacks, it helps to understand how potatoes behave through the season. Timing matters. Frost matters. Soil matters. Watering matters. And when potato plants struggle, the real reason is often much simpler than it first appears.

This page is designed as the main potato hub for Glorious Garden.

It brings together the main stages of growing potatoes in the UK, from planting time and early growth through to frost protection, common setbacks, and what usually makes the biggest difference to success. If you are growing potatoes for the first time, this page will help you understand the crop properly. If you have grown them before but had mixed results, it should help you see where things usually go wrong and what to improve first.

Quick Answers

Are potatoes easy to grow in the UK?

Yes, potatoes are one of the easier and more forgiving crops for UK gardeners, especially when timing and soil conditions are handled sensibly.

When should you plant potatoes in the UK?

That depends on the type of potato and your local conditions. For the full timing guide, read When to Plant Potatoes in the UK.

Do potatoes grow better in the ground or in containers?

Both can work well. Potatoes can grow successfully in beds, raised beds, large pots, or grow bags, depending on the space and soil you have.

Why do potato plants sometimes struggle?

Most potato problems come back to cold checks, frost damage, poor soil structure, weak drainage, or uneven growing conditions rather than one mysterious disease.

Are potatoes worth growing at home?

Absolutely. Homegrown potatoes are one of the most useful crops in a UK garden and often taste far better than people expect, especially when freshly lifted.

Why Potatoes Suit UK Gardens So Well

Potatoes fit the UK climate better than many warmer-season crops.

They are not tropical plants asking for endless heat. They are a practical crop that generally copes well with our cooler springs and milder summers, provided they are not pushed into the ground too early or left in poor conditions. This is one reason they are so popular with beginners. They are productive without feeling delicate.

They also suit different kinds of gardens.

Potatoes can be grown in:

• open ground
• raised beds
• containers
• grow bags

That flexibility makes them a very useful crop whether you have a traditional vegetable patch or just a smaller patio growing space.

The Main Stages of Growing Potatoes

The easiest way to understand potatoes is to think of them in stages.

Each stage has its own priorities, and many later problems can be traced back to something that went wrong earlier on.

The main stages are:

• choosing the right planting time
• getting the plants away well in suitable soil
• protecting early shoots from frost
• keeping growth steady through the main growing season
• spotting setbacks before they reduce the crop
• harvesting at the right stage

Once you start seeing potatoes this way, they become much easier to manage well.

Getting the Timing Right

Potato growing gets easier when the timing is sensible.

Many gardeners are tempted to start as early as possible, especially after the first few mild days of late winter or early spring. Sometimes that works well enough. But in many UK gardens, planting too early only creates avoidable setbacks. The soil may still be cold, sticky, and slow. Frost may still be a serious risk. Early shoots may appear before the season is actually ready to support them properly.

This is why potato timing is not really about chasing the earliest possible crop. It is about starting when your garden can actually support steady growth.

For the full month-by-month timing guide, read When to Plant Potatoes in the UK.

Why Frost Matters With Potatoes

Potatoes may suit the UK climate, but their early shoots are still vulnerable.

This catches a lot of people out. The crop itself may be fairly hardy once established, but fresh young growth can be damaged badly by frost. A mild spell encourages the shoots up, then one cold night leaves the plants blackened and checked before they have properly got going.

This does not always ruin the whole crop, but it can slow it down and reduce momentum at exactly the stage when good early growth matters most.

If frost protection is your main concern, read How to Protect Potato Shoots from Frost in the UK.

Where Potatoes Grow Best

Potatoes usually grow best in an open, sunny position with soil that drains reasonably well.

They do not need the hottest corner of the garden in the way tomatoes or cucumbers often do, but they do benefit from good light and soil that is not constantly wet and airless. A bright position helps the plants build strong leafy growth above ground, which then supports better tuber development below ground.

This is another reason site choice matters more than many beginners expect.

A bed that stays soggy after rain, compacts easily, or feels slow and cold for long periods will usually give poorer results than a lighter, more workable area that warms more readily in spring.

Potatoes in Beds, Raised Beds, and Containers

One reason potatoes are such a good beginner crop is that they can be grown in different ways.

In-ground growing is often the simplest where the soil is workable. Raised beds can be helpful where drainage is an issue or where clearer organisation makes the whole vegetable area easier to manage. Containers and grow bags are useful when space is limited or when the ground soil is awkward.

Each setup has trade-offs.

Containers usually warm faster and avoid poor ground altogether, but they dry out faster too. Beds often hold moisture more evenly, but the soil itself has to be suitable enough for the crop. Raised beds sit somewhere in between and can work very well for gardeners who want a neater, more manageable setup.

Why Soil Matters So Much for Potatoes

Potatoes are often described as forgiving, and they are, but they still respond strongly to soil quality.

What happens below the surface matters enormously with this crop. If the soil is compacted, badly drained, full of resistance, or very uneven in moisture, the plants often show it. Growth becomes slower. Tuber development is poorer. Harvest quality suffers. The plant may survive, but it never feels as though it really settled.

Good potato soil usually needs to be:

• reasonably loose
• reasonably workable
• free draining without drying excessively fast
• improved enough to support steady root and tuber development

This is why soil preparation often makes a much bigger difference than beginners expect. Potatoes are easier when the ground is ready for them rather than when they are pushed into whatever happens to be there.

If soil improvement is part of the problem, it helps to read How to Improve Garden Soil in the UK and How to Improve Garden Drainage in UK Soil.

How Potatoes Usually Go Wrong

When potatoes disappoint, the causes are often less mysterious than they first appear.

If you want the full troubleshooting guide for yellow leaves, weak growth, frost damage, and other recurring issues, read Common Potato Problems in the UK.

Common problems include:

• planting too early into cold conditions
• young shoots being checked by frost
• poor soil structure slowing development
• wet, heavy ground stressing the crop
• dry spells checking growth later on
• plants that simply never get enough momentum

This is why a struggling potato crop usually makes more sense once you stop looking for one dramatic reason and start looking at the whole run of conditions it has been through.

If your plants are already underperforming, read Why Potato Plants Are Not Growing in the UK.

Potatoes Need Steady Growth More Than Clever Tricks

If you want the full practical guide to watering, earthing up, protecting foliage, and keeping plants moving well through the season, read How to Care for Potato Plants in the UK.

A lot of potato success comes down to steadiness.

They do not usually need fussy day-to-day intervention, but they do need a season that supports them. A good start, soil that works, protection from frost when needed, and moisture that does not swing wildly from one extreme to the other will usually do more than any complicated technique.

That is one reason potatoes are such a satisfying crop. When the basics are right, they often reward ordinary sensible care very well.

What Healthy Potato Growth Looks Like

It helps to know what you are actually aiming for.

A healthy potato crop usually looks:

• steady rather than rushed
• upright and confident once established
• green without looking weak or pale
• as though it is building momentum through the season

If the plants remain hesitant, checked, or disappointing for too long, something usually needs looking at. Potatoes often tell you fairly clearly whether the setup is working.

Why Potatoes Are So Rewarding

Potatoes are not just productive. They are fun.

There is something very satisfying about seeing the leafy growth build, protecting the first shoots from a late cold snap, and then finally lifting the crop to see what developed below the soil. Even a modest crop feels worthwhile because potatoes are such a practical food to grow.

They also teach useful gardening lessons.

You learn about timing, frost awareness, soil preparation, moisture balance, and how much difference steady growth makes over a season. That makes potatoes a very good crop for beginners as well as a reliable one for experienced growers.

How Potatoes Fit Into a UK Vegetable Garden

Potatoes fit neatly into the wider rhythm of a UK vegetable garden.

They sit earlier in the season than many warm-weather crops and often help gardeners build useful momentum in spring. At the same time, they are not as cold-tolerant in their early leafy stage as people sometimes assume, which is why timing and frost awareness still matter.

That puts them in an interesting middle ground.

They are not fragile like tomatoes. They are not as carefree as quick leafy crops either. They are a solid, practical crop that rewards a bit of thought.

When Potato Plants Struggle

Potato plants that struggle often do so for simple reasons.

The crop may have gone into cold ground too soon. Frost may have checked the first shoots. The soil may have stayed too wet for too long. The bed may never have had the loose, workable structure the crop needed in the first place. Or later in the season, the plants may simply have run through a stretch of uneven moisture that slowed development below ground.

This is one reason potatoes are such a good teacher.

They show clearly whether the season has been working with them or against them.

If that sounds familiar, the best troubleshooting page is Why Potato Plants Are Not Growing in the UK.

Why Early Protection Matters

One of the easiest ways to lose momentum with potatoes is to let early shoots get hit by frost.

This is not always disastrous, but it is one of the most common avoidable setbacks. A plant that has to regrow after cold damage is already spending part of its season recovering rather than building forward.

That is why early protection can matter far more than people expect.

It is not about fussing over the crop endlessly. It is about understanding that young potato growth is often the most vulnerable stage. If that is the issue you want to solve properly, read How to Protect Potato Shoots from Frost in the UK.

What Usually Improves Potato Results Fastest

When gardeners want to improve a potato crop, the biggest gains usually come from simple changes rather than clever products.

The changes that most often help fastest are:

• using the right planting window
• improving soil structure before planting
• protecting early shoots from frost
• keeping growth reasonably steady through dry or difficult spells
• giving the crop a more suitable bed or container setup

Those are not dramatic answers, but they are the ones that usually work.

Potatoes Are a Good Crop to Learn With

Some vegetables are rewarding mostly because they taste good. Potatoes do that too, but they are also rewarding because they teach you useful gardening instincts.

You begin noticing when the soil is truly workable rather than just dry on top. You start watching spring nights more carefully. You begin to understand how much momentum matters in a crop that develops below ground rather than putting all its progress on display.

That is another reason potatoes deserve a proper place in a UK garden.

They are practical, productive, and genuinely useful for building gardening confidence.

Potato FAQs

A Sensible Place to Start

If you want better potatoes in the UK, start with the basics rather than trying to complicate the crop.

Choose the right planting time. Put them into soil that is workable enough to support steady development. Protect early shoots from frost when needed. Keep the season as even as you reasonably can. Then pay attention to how the crop responds.

Potatoes are not usually difficult because they are delicate. They are difficult when the early setup works against them and the season never really settles.

Get those basics right, and they are one of the easiest, most useful, and most enjoyable crops you can grow.

This catches a lot of beginners out. You plant at the right time, the first green growth appears, and then one cold night leaves the tops blackened, limp, or collapsed. It looks dramatic, and it is very easy to assume the whole crop has been ruined.

Usually, it has not.

If you want the full crop overview as well, read Growing Potatoes in the UK.

Potatoes are tougher than they look, and light frost damage to the shoots does not always mean the plant is finished. But repeated frosts, badly exposed growth, or unprotected early shoots can slow the crop down and reduce how strongly it gets going.

This is why frost protection matters so much in spring.

In the UK, potatoes are often planted while cold nights are still possible. In the UK, potatoes are often planted while cold nights are still possible. If you want to check how late frost may still be a risk in your area, use the UK Last Frost Dates by Postcode guide.

That is normal. The problem is not growing potatoes early. The problem is forgetting that the first top growth may appear before the weather has properly settled.

Quick Answers

Can frost damage potato shoots?
Yes. Potato shoots are tender and can be damaged by spring frost, especially when they are newly emerged.

Will frost kill potato plants completely?
Not always. Light frost often damages the top growth but the plant can regrow from below ground.

How do you protect potato shoots from frost?
The simplest methods are earthing up, covering with fleece, and checking the forecast during cold spring spells.

Should you cover potatoes every night?
No. Usually only during nights when frost is expected or likely.

What do frost-damaged potato shoots look like?
They often turn black, limp, dark green, or water-soaked after a cold night.

Why Potato Shoots Are at Risk in the UK

Potatoes are often planted early in the UK because they are a cool-season crop and need a decent run of time to develop well.

That is fine, but it means the first shoots often appear while spring weather is still unreliable. Warm days can encourage growth, then cold clear nights can catch the new foliage before the garden has fully moved out of frost season.

This is especially common in March, April, and early May.

It can also be worse in exposed gardens, frost pockets, and lower-lying areas where cold air settles overnight. A garden can feel mild by day and still produce a hard cold dip near dawn.

This is one reason timing in UK gardens is about more than the calendar alone.

If you want the wider seasonal picture, read When to Plant Potatoes in the UK and When to Plant Vegetables in the UK.

What Frost Damage on Potatoes Looks Like

Frost-damaged potato shoots usually look obvious once the temperature rises again.

The leaves and stems may turn black, dark green, limp, or slightly translucent. Sometimes the tops collapse altogether and look as if they have been scorched.

It can look worse than it really is.

The damage is usually most visible on the exposed top growth. If the underground part of the plant is still healthy, potatoes can often push up fresh new shoots after the damaged growth is removed or dies back naturally.

The important thing is not to panic too quickly.

One frosted top does not automatically mean the plant or the crop is lost.

Does Frost Always Ruin the Crop?

No, not always.

Light frost damage is often a setback rather than a disaster. Potatoes can regrow, especially if only the emerging shoots or upper leaves were affected. What usually suffers most is momentum. The plant may need time to replace damaged top growth before it gets back into steady development.

More serious or repeated frost can be more damaging.

If the plant is hit hard several times, early growth is repeatedly checked, and the crop can become slower and weaker than it should have been. That is why protection matters most when the shoots are first appearing.

The Best Way to Protect Potato Shoots

The simplest and best method is earthing up.

This means drawing soil up around the stems so the vulnerable lower growth is covered. It protects the shoots from frost and also helps keep developing tubers covered later on.

For many UK gardeners, this is the most practical answer because it is quick, cheap, and effective.

If frost is forecast and the shoots are only just through, covering them with extra soil often gives enough protection to stop the worst damage.

You do not need to wait until the plants are large.

In fact, early action is often the whole point. Once the shoots are well exposed, they are much more vulnerable.

Using Fleece to Protect Potatoes

Garden fleece is another very useful option.

If you already have rows up and growing, fleece can be laid over them during cold nights to take the edge off frost. This is especially useful if earthing up alone is not enough or if you are trying to protect a larger bed quickly.

Fleece works best when put on before the cold night arrives, not after the damage is done.

It does not have to be complicated. The goal is simply to create a protective layer that reduces how sharply the temperature drops around the plant.

If you are growing in bags, containers, or smaller beds, fleece can be especially helpful because those setups can cool down faster than open ground.

Can You Use Straw, Buckets, or Other Covers?

Yes, in many gardens you can.

Temporary covers such as straw, tubs, buckets, or overturned pots can help protect small amounts of growth during a cold snap. These are often useful when only a few shoots have appeared and you want a quick practical fix.

The main thing is to remove or loosen covers again once the risk passes, so the plants still get light and airflow.

You are trying to protect the shoots overnight, not smother them for days.

In the next part, we’ll cover when to start protecting potatoes, what to do after frost damage, and how to reduce the risk in future.

When Should You Start Protecting Potato Shoots?

You should start protecting them as soon as shoots are visible and frost is still possible.

This is the point many gardeners miss. They think frost protection only matters once plants are well up, but the earliest growth is often the most vulnerable. A few centimetres of green top growth is enough to be damaged if the night turns cold.

Checking the forecast matters here.

You do not need to cover potatoes every night for weeks on end. You just need to be alert during periods when clear cold nights are likely. In many UK gardens, the risk is highest in spring while daytime conditions are improving but nights still dip sharply.

If your garden is in a frost pocket, exposed area, or colder part of the country, be extra cautious.

Those small local differences often matter more than the general forecast.

What to Do if Potato Shoots Have Already Been Frosted

The first thing is not to rush into digging anything up.

Frost-damaged tops often look dramatic, but the plant below ground may still be perfectly alive. Give it a little time and watch what happens. If the roots and underground stem are healthy, new growth often emerges from below.

If the damaged top growth has clearly collapsed, you can leave it for a short while and then tidy it once you are sure what is dead.

There is no benefit in panicking and lifting the crop too early. In most cases, patience is the better response.

Once the damaged shoots are dealt with, protect any fresh new growth if more frost is expected.

This is important because a plant that is trying to recover does not need another setback straight away.

Should You Cut Off Frost-Damaged Leaves?

Usually, only once it is clear they are properly damaged.

If leaves are blackened, limp, and obviously not recovering, they can be removed or left to die back naturally before tidying. If there is still some doubt, it is often better to wait a little rather than cut too quickly.

The plant will usually tell you what has survived and what has not.

New growth coming through is a good sign that the main plant is still active below ground.

Do Potatoes in Bags and Pots Need More Frost Protection?

Yes, often they do.

Potato bags, tubs, and containers can be more vulnerable because the compost and root zone warm up and cool down faster than open ground. That makes them especially responsive to spring weather swings.

If you are growing potatoes this way, it is worth keeping fleece or another temporary cover nearby during risky periods.

You can also move smaller containers to a more sheltered position if needed, which is one advantage of growing in pots or bags.

If you use containers a lot, it also helps to read Can You Grow Vegetables in Pots in the UK?.

How to Reduce the Risk of Frost Damage in Future

The best way is to combine good timing with simple protection.

You do not need to avoid early potatoes altogether. You just need to expect that early growth may need help. Earthing up, watching the forecast, and keeping a few covers ready usually solves most of the problem.

Avoid planting in the coldest, most exposed part of the garden if you can help it.

And if your garden is known for catching late frosts, it can be worth delaying very early plantings slightly rather than rushing to be first.

This is the same wider principle behind many spring gardening decisions in the UK. A slightly later start in better conditions often gives stronger, steadier growth.

Are Some Potatoes More Vulnerable Than Others?

Early potatoes usually face the greatest frost risk simply because they are up sooner.

That does not make them a bad choice. It just means they are more likely to meet unsettled spring weather while still tender. Maincrop potatoes often emerge later when the risk has begun to drop, though that depends on planting time and region.

The real issue is usually timing and exposure rather than one variety being inherently weak.

Is It Better to Delay Planting Potatoes to Avoid Frost?

Sometimes, but not always.

Delaying can reduce the chance of frost damage to the first shoots, but it also shortens the growing season. For many gardeners, the better answer is to plant at a sensible time and be ready to protect the crop if cold nights return.

This is especially true for first earlies.

If you delay too much, you can lose the very advantage that makes early potatoes appealing in the first place.

Quick Signs Your Potatoes Are Recovering

Good signs include:

fresh green shoots appearing from lower down,
firm stems below the damaged part,
and the plant starting to look active again within a short time.

If that happens, the crop is usually back on track, even if it has lost a little time.

Frequently Asked Questions

A Sensible Place to Start

If you want to protect potato shoots from frost in the UK, keep it simple.

As soon as shoots appear, stay aware of the forecast. Earth up plants when needed, use fleece or temporary covers on risky nights, and do not panic if frost catches the tops once. In many cases, potatoes recover well if the damage is light and the plant is protected afterwards.

The real aim is not to eliminate every risk. It is to stop a normal spring cold snap from turning into repeated setbacks.

When to plant potatoes in the UK depends on the type, but the short version is this: first earlies go in from mid March, second earlies from early April, and maincrop from mid April into early May. The one rule that overrides all of it is frost. Potato shoots are killed by it, so wherever you are, the soil needs to be warming and the worst of the frosts behind you before the tubers go in. Get the timing right and potatoes are about the most rewarding crop a beginner can grow. Plant into cold wet ground and they just sit there and sulk.

Potatoes were the first thing I ever grew that made me feel like a proper gardener. They are forgiving, they crop heavily, and there is nothing quite like tipping out the first bucket of earlies and finding it heavier than you expected. But they taught me the timing lesson the hard way, because the one year I rushed them into cold March ground on the back of a mild week, half the row got frosted as it emerged and the other half rotted before it started. So this guide is built around the two things that actually matter: the type you are growing, and the state of the soil you are putting it into.

The Short Answer, by Potato Type

Potatoes are sold in three groups, and the group decides the planting window far more than the calendar does. First earlies are the new potatoes you plant from mid to late March and lift in June and July, small, waxy and worth growing for flavour alone. Because they come out of the ground early, they usually dodge the late blight that arrives later in summer. If you are buying seed, look for first early seed potatoes like Rocket or Swift.

Second earlies follow on, planted from early to mid April for a mid-summer harvest, which makes second early seed potatoes such as Charlotte a good middle option. Maincrop are the big storing potatoes, planted mid April through early May and left in the ground the longest, giving the heavy crop you dig in autumn to see you through winter. Maincrop varieties need the most space and the most patience, but they also give the most food. If you want the wider growing detail rather than just the timing, that lives in how to grow potatoes in the UK.

Soil Temperature Beats the Calendar

Every planting date on this page is a guide, and the soil overrules all of them. Potatoes want soil that has warmed to around 7 to 10C before they will do anything useful, and a thermometer pushed into the ground tells you more than any date printed on a seed packet. That is the mistake I made: I trusted the mild air in March and never checked the soil, which was still cold and wet a few inches down.

The feel of the soil is a decent guide if you have no thermometer. If it is cold and sticky and clings to your boots, it is too early. If it has dried enough to crumble in your hand, it is close. On my heavy Oxfordshire clay that point always comes later than the books suggest, sometimes two or three weeks later than lighter soils down the road, which is worth remembering if you garden on clay. Covering the bed with black plastic or cloches for a fortnight beforehand genuinely helps, and if your ground stays wet it is worth improving the drainage before you do anything else.

Should You Chit Potatoes First?

Chitting means letting seed potatoes sprout before planting, and it is one of those jobs that sounds fussier than it is. Stand them in an old egg box on a cool, bright windowsill a few weeks before planting, eyes pointing up, and let them grow short green shoots. It gives them a head start and is genuinely worth doing for first earlies, where every week earlier means an earlier crop.

For maincrop it matters far less, and plenty of good growers skip it entirely. The one thing to avoid is chitting somewhere warm and dark, which gives you long, pale, brittle shoots that snap off when you plant. Cool and light is the whole trick. If you are ordering online, some gardeners stick to reliable seed potatoes suited to UK conditions rather than gambling on supermarket ones, which are often treated to stop them sprouting.

Month by Month

March

First earlies go in from mid to late March in most of the country, once the soil is workable and the shoots have somewhere warm enough to emerge into. In the north, hold off until the end of the month or into April. This is also the month to finish chitting and to get beds prepared.

April

The busiest potato month. Second earlies go in early to mid April, maincrop from mid April onwards, and any first earlies you did not get in during March. Keep an eye on the frost forecast, because early shoots can appear within a few weeks and they are vulnerable the moment they break the surface.

May

Your last chance for maincrop, ideally in the first half of the month, and the main job now shifts to earthing up the earlier plantings as they grow. May-planted potatoes still crop well, they just run later into autumn, so lift them before the first frosts. There is more on the wider month in my guide to what to plant in May.

Frost Is the Real Enemy

The tubers underground are safe enough, but the moment shoots break the surface they are at the mercy of a cold night. A single sharp frost blackens the new growth, and while the plant usually recovers by pushing out fresh shoots, it loses time and yield doing it. This is the single biggest reason not to plant too early.

Two things protect them. The first is earthing up: drawing soil over emerging shoots buries and insulates them, which is why the job does double duty. The second is fleece on frosty nights, and garden fleece thrown over the row when a frost is forecast is cheap insurance. If you would rather not lose plants at all, I have gone through the options in detail in protecting potato shoots from frost, and if a frost has already caught you out, frost damage on plants covers the recovery. Check your own dates with the last frost date checker before you commit.

Where You Live Shifts the Dates

The dates above are for the middle of the country, and the UK spreads them out by a month from end to end. In the South West and along the south coast, mild winters mean first earlies can go in from late February in a good year, and the whole season runs early. London and the South East are similar, helped by the warmth cities hold. Across the Midlands the standard dates apply as written.

In northern England, push everything back a couple of weeks and start earlies in early April rather than March. In Scotland, later still, with earlies going in mid to late April and the whole season shifted right, though Scotland grows superb seed potatoes precisely because its cool climate keeps them healthy. Local knowledge beats any of this, and the wider picture for everything else going in at the same time sits in the vegetable planting calendar.

How Deep, and How Far Apart

Plant tubers about 12cm deep with the shoots pointing up. Spacing depends on type: first and second earlies want roughly 30cm between tubers with 45 to 60cm between rows, while maincrop need more room, around 40cm apart with 75cm between rows, because they build bigger plants and bigger crops. Crowding maincrop is a false economy, since the plants shade each other and the tubers stay small.

The depth matters because potatoes form on the stem above the seed tuber, not below it, which is the whole reason earthing up works. There is a full guide to how to care for potato plants once they are in. Too shallow and the developing potatoes push up into the light and turn green, and green potatoes are mildly toxic and best not eaten. A bit deep does no harm; too shallow does.

Earthing Up as They Grow

Once the plants reach 15 to 20cm tall, draw soil up around the stems to form a ridge, leaving just the top few centimetres of leaf showing. Repeat it every couple of weeks as they grow. It sounds like a chore and it is the job that does the most for your crop, protecting shoots from late frost, stopping tubers greening, and giving the plant more buried stem to set potatoes along.

A draw hoe makes short work of it, and a garden hoe is the one tool I would not want to be without at potato time. On a small bed you can do it by hand, but your back will notice.

Potatoes in Bags and Containers

If you have no bed, or heavy soil you would rather not fight, potatoes grow brilliantly in bags and large containers, and first earlies are the best type for it. A big tub or a purpose-made potato bag, a couple of seed potatoes, and you are away. The compost warms faster than open ground too, so you can often plant a little earlier.

Start with about 15cm of compost, sit the tubers on it, and cover. As the shoots grow, keep adding compost to bury the lower stems, exactly like earthing up, until the container is full. The one thing bags punish is drought, because they dry out fast and a potato that runs short of water gives you a poor, knobbly crop, so keep them well watered once the plants are growing strongly.

When Will They Be Ready?

Roughly speaking, first earlies are ready about 10 to 12 weeks after planting, second earlies 13 to 15 weeks, and maincrop 18 to 20 weeks. So a mid-March first early is often ready to lift in June, while a late-April maincrop keeps you digging into September and October.

Earlies tell you they are ready when the flowers open, and the best test is simply to dig up one plant and see. Maincrop are left until the foliage yellows and dies back, then given another couple of weeks in the ground so the skins set firm for storage. If your plants are not growing as they should along the way, potato plants not growing works through the usual causes, and common potato problems covers the rest.

Planting Mistakes Worth Avoiding

Four things cause most potato disappointment, and they are all about timing and soil rather than skill. Planting into cold waterlogged ground, which rots the seed before it starts. Going too early on a mild spell and losing the shoots to frost. Overworking wet soil into a compacted mess, which potatoes hate. And planting too shallow, so the crop greens in the light.

Every one of those is avoidable by waiting for the soil rather than the date, and by keeping fleece to hand for the first few weeks after the shoots appear. Blight is the other big one, but that is a summer problem rather than a planting one, and choosing first earlies that crop before it arrives is half the answer.

Quick Reference

• First earlies: plant mid to late March, harvest June to July
• Second earlies: plant early to mid April, harvest July to August
• Maincrop: plant mid April to early May, harvest September to October
• Soil temperature: aim for 7 to 10C before planting
• Depth: about 12cm, shoots pointing up
• North and Scotland: push all dates back two to three weeks

If it all feels like a lot, boil it down to this. Buy first earlies, chit them on a windowsill, and plant from mid March once the soil is no longer cold and sticky. That single row will teach you more about potatoes than any guide, and earlies are quick, forgiving, and almost impossible to get badly wrong.

Above all, watch the soil rather than the date, and keep a bit of fleece by the back door for the first few frosty weeks after the shoots come up. Do that and your biggest problem will be finding somewhere to store the crop. It is the vegetable I would tell any nervous beginner to grow first, because few things give so much back for so little.
