May

What to do this Month – May

Vegetables

1. Sow French beans, runner beans, squash, cucumbers and pumpkin seeds directly into prepared beds outside. Be alert to late frosts, and if necessary cover tender seedlings with cloches or biodegradable or re-used old fleece.
2. Sow sweetcorn outside in blocks, at least 45cm (18in) spacing, with two seeds per hole. The strongest seedling can be selected later.
3. Sow cauliflowers and purple sprouting broccoli for harvesting next winter.
4. Try sowing some unusual vegetables such as kohl rabi (like a large white above-ground turnip), scorzonera and salsify.

Fruit

1. Remove wayward shoots on fan-trained trees and tie in better placed ones.
2. Thin out crowded raspberry shoots.
3. Thin gooseberries if you want large fruit.
4. Water blueberries, cranberries and lingonberries when needed with rainwater, but use tap water when butts are empty.
