Growing second early potatoes outdoors for a summer harvest.
01
Chit Seed Potatoes
24 Jan to 23 FebChit second-early seed potatoes around 24th January - 23rd February. Arrange them in a single layer somewhere cool and light for a few weeks so they develop short, sturdy shoots.
02
Plant Second Earlies
28 Mar to 18 AprPlant chitted second earlies around 28th March - 18th April in prepared soil. Set tubers deep and apart, with about between rows. Cover, firm gently and water in. Use fleece if a late frost is forecast.
03
Earth Up
11 Apr to 13 Jun Dates as each sowing reaches this stageAs the second early potato shoots grow to ~15cm, periodically hill up soil around their stems. This protects the young potatoes from sunlight and supports the plant. Continue earthing up every week or two until flowering, leaving just the tops of the plants exposed each time.
04
Harvest
20 Jun to 8 Aug Dates as each sowing reaches this stageLift second-early potatoes through 20th June - 8th August once plants have flowered and the foliage starts to yellow. Dig carefully, allow tubers to dry for a few hours, then use fresh or store briefly somewhere cool and dark.
