From earthy new potatoes and bite-sized salad varieties, to floury bakers and roasters, the humble potato remains the nation’s favourite vegetable. If you’re a potato aficionado, there’s a huge number of exciting potato varieties you can grow that you’ll never see in the shops.


How to grow potatoes at home

Prepare the soil by digging and removing weeds, and then dig straight trenches 12cm deep and 60cm apart. Plant seed potatoes 30cm apart and cover them with soil to fill the trench. When the shoots reach 20cm tall, use a rake, hoe or spade to mound soil up around the bases of the shoots, covering the stems half way. This is called earthing up.

Planting out seed potatoes

How to grow potatoes – chitting seed potatoes

Grow your own potatoes from ‘seed potatoes’, which are small potato tubers rather than actual seeds. You can buy seed potatoes from late winter. Don’t be tempted to grow potatoes from old potatoes from the veg rack, as they won’t produce reliable crops.

Before planting, you need to ‘chit’ your potatoes. This involves letting the potatoes grow shoots, which will give you a bigger potato crop. Place seed potatoes in trays or egg cartons with the end that has the most eyes uppermost. Stand in a cool, light spot until 1-2cm long shoots have formed. This could take up to six weeks.

Home-grown potatoes do well in all types of soil, but the richer the better, so dig in plenty of well-rotted organic matter, such as garden compost. An open, sunny site is best.

While maincrop potatoes grow well in the ground, early or salad potatoes will also do well in containers. Polypropylene potato growing bags are designed especially for this purpose and are handy if you’re short of space. However, you can also plant potatoes in an old compost bag, with similar results.

Here, Monty explains how to grow potatoes in a bag:

When growing potatoes in the ground, plant earlies and salad types in March, 12cm deep and 30cm apart, with 60cm between rows. Plant maincrop potatoes later, in April. These need to stay in the ground longer and require more space to produce a decent crop. Plant them 12cm deep and 38cm apart, with 75cm between rows. Plant potatoes with the shoots (or ‘eyes’) facing upwards.

Growing potatoes: caring for your crop

Water potatoes regularly, especially during warm, dry spells, and keep the soil weed free. As the potato plants grow, use a spade or hoe to cover the shoots with soil to stop the developing tubers becoming green and inedible. This is called ‘earthing up’. Leave the top few centimetres poking out the top. As plants continue to grow you will need to earth them up again.

Growing potatoes: problem solving

How to grow potatoes - potato blight
How to grow potatoes – potato blight

Slugs can be a problem, especially if growing potatoes under black plastic.

Potato blight is a fungal disease, which turns foliage yellow with dark patches and causes the tubers to rot. Grow a blight-resistant potato variety to avoid the problem. You can also cut the potato plants down at the first sign of infection, as the fungus will not have reached the tubers by that stage. Then harvest the tubers as soon as you can.

Never grow potatoes in the same soil year after year as this could lead to a build up of pests and diseases. These include potato eelworm, which causes stunted growth and poor cropping.

Harvesting potatoes

Depending on the type of potato you are growing, you’ll have crops from May to October.

Lift earlies and salad potatoes when the plants are still flowering and the potatoes are about the size of a large hen’s egg. Cut the potato plants (also known as haulms) to the ground, then gently prise the plants out of the ground with a fork. Dig up the potatoes as and when you need them.

Leave maincrop potatoes in the ground until the leaves turn yellow and die down. Choose a dry day to dig up your crop. Cut the plants to the ground and dig up your potatoes, discarding any damaged ones.

Wash and scrub potatoes before frying, boiling, baking, mashing, roasting or sautéeing – this has to be the most versatile vegetable!

Health note: never eat potatoes raw. Green potatoes contain a chemical called solanine, which they develop when exposed to light. It can cause severe stomach upsets.

Storing potatoes

How to grow potatoes – how to store potatoes

Home-grown potatoes, particularly maincrop potatoes, will store well for many months in a cool but frost-free place. Only store perfect tubers, removing any showing signs of damage, and don’t wash them before storage. All light must be excluded to avoid potatoes turning green and poisonous. Hessian or thick brown-paper sacks are available for the job. Check crops in store regularly, removing any rotten ones.

Advice for buying potatoes

  • Potatoes are available from a range of garden centres and nurseries, with many offering online sales. If you’re a member of an allotment association, you may be able to buy potatoes direct from the ‘allotment shop’ at a reduced price
  • Choose between first earlies, second earlies and maincrop potatoes, depending on when you want to to eat your potatoes and if you have a problem with blight (first and second earlies are usually harvested before blight hits)
  • Check the seed potatoes thoroughly when they arrive/before you buy. Make sure they’re firm and avoid any with very long roots or any with signs of mould
