Make the most of your space
Potatoes, while popular with the first time kitchen gardener, take up a lot of space, require a lot of water, and are hungry feeders so will deplete your soil. They are also quite cheap to buy, and in the space taken up by a single row of potatoes you could sow a row of early carrots and plant a row of leeks, then when the carrots have been cropped, you could plant some ‘cut and come again’ lettuce. In other words, the space in your kitchen garden given over to potatoes could be worth much more, giving you a greater return in terms of variety and value of crops.
