- Continue sowing salad crops, such as beetroot, Chinese cabbage, pak choi and radish. Leafy salad crops may do better when sown in partially shady sites since hot dry weather can lead to bitter tasting leaves.
- Sow French, runner and broad beans, peas, squash, sweetcorn, and outdoor cucumbers directly into prepared beds outside.
- Sweet corn works best planted in blocks, at least 45cm (18in) spacing, with two seeds per hole. Any seeds sown earlier under cover can now be planted out into the same block pattern. Sow before mid June.
- Courgettes, marrows and pumpkins can still be sown outdoors in early June.
- Although most winter brassicas need to be sown earlier in the season, calabrese, turnips and kohl rabi can be sown now for an autumn crop.
- Pull off suckers appearing around the base of fruit trees.
- Thin pears, plums, peaches, nectarines and apricots. Apples should be thinned at the end of the month.
- Summer prune red and white currants and gooseberries.
- Shorten newly planted raspberry canes once new shoots are produced.
- Peg down strawberry runners and remove cloches from outdoor strawberries once cropped.
