When your potatoes are ready for planting, dig a trench to plant them in. The trench should be about 10cm deep but this can vary depending on the exact variety you are planting. Adding a sprinkling of fertiliser to the trench, before you plant, is a good way to give your potatoes an extra boost.
Set the seed potatoes into the trench, with the shoot facing upwards, and leave around 25cm between each seed. When all your seeds are planted, cover them lightly with soil and water well.
In 2 square metres of garden you could grow about 10 plants, each producing upwards of 10 potatoes.
