Colourful, hardy, and can provide leaves right through winter if protected.

Sowing & Growing Tips
- Water new sowings well—August can still be dry.

- Use fleece or mesh to shade seedlings from hot sun and protect against flea beetles.
- Thin seedlings early for strong, healthy plants.
Bonus Crops
- Coriander and Parsley (Herbs):
Less likely to bolt in late summer and thrive into autumn. - Overwintering Onions:
