Potatoes (Solanum tuberosum) are one of the most popular and versatile of all the garden vegetables. An important food crop and key ingredient of many British recipes. Very easy to grow and generally trouble free, if good quality "certified" disease-free tubers are used.

Growing Conditions

Soil Type: A deeply dug, well-manured soil is best.

Conditions: Full sun.

Ease of Cultivation: Very easy.

Type: Root (stem tuber) vegetables.

When to Sow: March to April.

Harvest Season: Early summer to autumn (depending on variety).

Planting and Growing Potatoes


To get a head start, place seed potatoes (tubers) on trays in an airy and frost-free place to enable them to sprout (chit), a few weeks before planting out. Keep them in the light but out of direct sunlight. Although you can still plant them without chitting, they will just take a little longer to mature.

Potatoes are greedy feeders so work plenty of organic matter or compost into the soil to improve its texture and provide nutrients. They prefer a slightly acid soil so do not add any lime.

For the earliest potatoes grow in a south facing border, preferably sheltered by a wall. Do not plant before mid-February. In heavy soils plant after mid-March.

When to Sow

Plant First Early and salad potatoes in late March. Plant them 4in (10cm) deep at 12in (30cm) intervals in rows. Space the row about 2ft (60cm) apart.

Plant Second Early potatoes from early to mid-April, 4in (10cm) deep at 12-14in (30-36cm) intervals in rows 28-30in (70-75cm) apart.

Plant Maincrop potatoes from mid to late April, 4in (10cm) deep at 16-18in (40-45cm) intervals in rows 28-30in (70-75cm) apart.

The usual planting method is to draw (scrape out) a trench about 4in (10cm) deep with a draw hoe and place the potatoes in it. Then draw back the soil from the sides to cover them.

TIP: If you have comfrey, place a layer of comfrey leaves on the bottom of your trench before planting. This will quickly rot down to and help to fertilize the crop.

Potatoes are tender plants and a late frost can quickly kill the emerging foliage, therefore keep an eye on the weather in your area and don't be tempted to plant too early. If the leaves start to show and frost is forecast, protect the plants with horticultural fleece or draw a little soil over them with a hoe.

Growing Potatoes in Bags and Containers

Potatoes grow really well in deep containers and specialist potato grow bags/sacks. Simply place a good layer of soil in the bottom of the container or bag (with the sides initially rolled down) and cover the tuber with 4in (10cm) of soil. As the plant grows add more soil to earth it up, until the leaves reach the top of the bag (unrolling the bag as it grows up).

Taking Care of Potatoes

All varieties should be earthed-up as they grow, by drawing the earth from the sides of the rows over the plants. This is mainly to prevent tubers near the surface going green, which is toxic, so these would need to be discarded. It also has the advantage of increasing the yield.

Apply a good dose of general purpose fertilizer after a month's growth. Water well in hot dry weather, as an irregular water supply can reduce the yield.

Pests and Diseases

Protect from slugs and wireworm, which bury underground to find the tubers. Nematodes are a very effective defence for these pests and one of the best organic controls. If slugs are a problem in your area, grow cultivars resistant to slugs.

Potato blight or late blight (Phytophthora infestans) can be a problem in prolonged wet weather, causing rotting. Early varieties are less affected as they are usually harvested before blight becomes a problem.

Harvesting & Storing Potatoes

Harvest earlies after the plants have flowered, usually around 16 weeks after planting. Dig up a few plants at a time, leaving the rest to continue growing and increase.

Harvest maincrop varieties after the tops have died down, usually after about 22 weeks. Maincrops can be dug up in whole rows once they mature and stored. Choose a dry sunny day and leave them on the surface for a few hours to harden the skin, which will help them store better.

Ensure you dig all the tubers out once the crop has finished, including any tiny tubers, as these are bound to sprout again next year.

Storing Potatoes

Store maincrop potatoes in dry hessian or specialist paper sacks with air holes. Exclude all light or the tubers will turn green and become inedible. Store at around 5°C and protect from frost. Check them regularly. Discard or use up any damaged ones first, as one rotten tuber can quickly spread through the whole batch.

Cooking Potatoes

Potatoes are a very versatile vegetable in the kitchen. They can be peeled and boiled, mashed, roasted, fried or cooked in their skins. Different varieties are suited to different cooking methods. Therefore the desired method of cooking should be considered when choosing a variety to grow.

Popular Varieties of Potatoes

There are hundreds of varieties to choose from - far more than you will ever find for sale in the supermarket. Different varieties grow better in certain areas and soils than others. So ask your neighbours what does well in your area. If you are still undecided what to grow, buy several smaller packs of around 10 seed potatoes and try different types until you find what you like.

Don't plant potatoes purchased from food stores. Although they will grow, more often than not they will produce a poor crop or one that is subject to disease. It is best to buy good quality seed potatoes that have been 'certified' as disease-free.

Note: Seed potatoes are available from garden centres in the spring.
