Water, water, everywhere...Once you’re certain the frosts have passed you can plant out outdoor tomatoes, aubergines, peppers, sweet corn, French beans and runner beans. For many of us, tomatoes will be a favourite to grow either in the greenhouse in beds and soil/compost that has been changed annually, in grow bags, or outdoors. When planting outdoors give them the sunniest spot possible and stake well. Plants should be about 15-23cm/6-9” tall with the first flower truss appearing.
Brassicas can be planted out now. Your broccoli, Brussels sprouts, cabbage, cauliflower and kale should be ready to go into the ground. If the weather has been wet you’ll probably need to keep weeding – use a hoe between rows of vegetables such as leeks and onions.
If it’s dry and hot the vegetables will need a good spray with plenty of water and watch out for any in pots, containers and grow bags which are susceptible to drying out quickly. Continue sowing for a succession of salad crops, lettuce, endive, radishes and root vegetables, including carrot, beetroot and swede for winter. Plants in full growth will benefit from applications of weak liquid manure or other fertiliser. Harvest asparagus, early potatoes, peas sown in autumn and broad beans.
- Sow spinach beet, Chinese cabbage
- Sow chicory for forcing
- Blanch leeks planted in trenches in April
- Lift autumn sown onions and potatoes as required.
- Thin out vegetable seedlings
