Unless your garden is a warm and sheltered one, March’s awful weather made it impossible to plant seed potatoes outdoors, but there’s still plenty of time to get the seed tubers in the ground. Ideally wait for a dry day and until soil conditions are favourable (so not sodden or frozen).
Potatoes are greedy feeders that like a really fertile, moisture-retentive but free-draining soil in full sun so prepare the ground well before planting. Alternatively if space is limited potatoes will quite happily grow in containers or ‘potato planters’. At The Orchard we have an excellent selection of seed tubers of both ‘earlies’ and maincrop varieties, including some with good resistance to blight.
