Summer Month Guides
Summer Priorities
- Water tomatoes, courgettes, and beans consistently — irregular watering causes blossom end rot and splitting
- Feed tomatoes weekly with high-potash feed once first trusses set
- Harvest courgettes at 10–15cm — leaving them to grow into marrows stops the plant producing
- Pick runner and French beans every 2–3 days — leaving pods to mature stops production
- Sow spring cabbage and winter brassicas in June–July for autumn planting
- Sow autumn salads (radishes, lettuce, rocket) from August
