Rocket Planting Calendar
| Task | Timing | Notes |
|---|---|---|
| First sowing (under cover) | February – March | Cloche or cold frame; soil temp min 5°C |
| Main outdoor sowing | March – May and August–September | Avoid midsummer; heat causes bolting |
| Harvest | April – November | Cut leaves when 8–10cm; plant regrows 2–3 times |
Key Tips
- Succession sow every 2–3 weeks — rocket bolts quickly; small frequent sowings give a continuous supply
- Skip July sowings in most regions — heat causes bitter leaves and rapid bolting
- Sow again in August–September for a good autumn/early winter harvest
