So, you want to grow potatoes? Well, you'll be pleased to know that you don't need a massive garden or allotment to do it. You can even grow a tasty crop in a small urban plot, using a pot or container with a capacity of at least 10 litres.
Start them off now and you should be enjoying tasty potatoes from July through to the end of the year. All that'll be left to do is decide: chips, mashed or jacket?
Here's how...

Excessive wet weather can lead to the gardener's nemesis - blight - which can ruin your crop in one fell swoop.
But there's a range of blight-resistant 'superspuds' known as Sarpos (pronounced Sharpo). They are now being grown by gardeners who don't want the plight of blight. Blue Danube is a good blight-resistant variety with a deep blue/purple skin (but white flesh).
Early varieties of seed potatoes should be "chitted" in January and February before planting out (you don't need to chit maincrop types as they have a longer growing season).
Chit them by laying the potatoes rose-end (where most of the tiny sprouts are) on newspaper in clean seed trays or old egg boxes, placed on a windowsill or in a frost-free greenhouse in a light position but not in direct sunlight.
In a few weeks, the shoots will grow, gaining strength while the soil is still too cold for them to be planted outside.
Rub off all but the four strongest sprouts and when they have grown to around an inch, chitting is completed. Don't plant them out until the end of March, though, as the shoots will take time to develop.
Plant tubers of seed potatoes around 15cm deep and 40cm apart in rows 60cm apart. Second earlies and maincrop potatoes should be planted 40cm apart allowing 75cm between rows.
Potato foliage should soon cover the ground and you won’t need to weed any more, while potatoes rarely need watering, unless you get a prolonged period of drought in summer.
Start digging earlies as soon as the tubers are a fair size. Push your hand under a plant to feel for egg-sized tubers, or lift an individual plant gently using a fork.
When the plants start to flower is a good indication that the tubers are ready to harvest, although you could ease out some earlies by ferreting under the soil with your hand and pulling a few out, without pulling up the plant, which will continue growing. They should keep in a cool, airy shed in the dark, or the vegetable drawer of the fridge, for a week or more.
Second earlies can be lifted for storage later, but try to use them before you start on the maincrops. With maincrops, leave the plants to die down completely.They keep quite well in the soil but lift them before the ground becomes really wet or else they are likely to rot.
Dry out maincrops in a dark shed for a couple of days before storing them in hessian or paper sacks, until required.
