Plant potatoes if your soil is warm enough
Wait until the soil is warm enough before planting potatoes – if grass and weeds are growing, it should be fine. Start earthing up as the shoots start to show, paying special attention if frosts are forecast. If frost is forecast, protect early, young potato shoots. They’ll need protection even in unheated greenhouses and tunnels, as well as outdoors. Earth them up or cover with newspaper, net curtain or horticultural fleece overnight.
Harden off sweet peas
Plant out sweet peas and tie in if they are tall enough and hardened off. Provide support with twigs or string or pea netting.
Sow hardy annuals
Hardy annual seeds can be sown directly into the open ground, but wait until you can see weeds growing strongly before sowing.
Plant herbaceous perennials
You can still plant herbaceous perennials such as Geranium, Astrantia and Oriental poppies. Check that the plants you buy have strong, green shoots and plant them into well-prepared soil.
Protect fruit blossom
Cover blossoming fruit trees with sheets of fleece on frosty nights to protect embryo fruit.
