May is a busy month as you can start planting outside (frost warning )your tender crops like tomatoes, courgettes, peppers and pumpkins. There's still a risk of late frosts in some areas as we have seen this week , so keep an eye on the weather this month, and cover plants with fleece if frosts are forecast.
More jobs to do
Remove sideshoots from tomatoes: Pick out sideshoots from cordon tomatoes as you see them developing from this month on.
Earth up potatoes: Draw up soil around the stems of the potatoes when the shoots are 23cm (9in) high, in order to prevent the new tubers going green.
Sow sweet corn: In blocks, at 45cm (18in) spacing, with two seeds per hole.
Harden off tender plants: Acclimatise tender plants to the colder outdoor conditions for 10 to 14 days before planting into final positions.
Feed fruit in pots: Use a liquid fertiliser and feed fruit growing in pots.
