Sow this month — when would you harvest?
Assuming you sow in mid-September, then adding up the warmth Melbourne usually gets, one day at a time — which is why some of these run past the end of the month.

|---|---|---|
| 🌿 Rocket | 39 | Oct 23 |
| 🌿 Spinach | 52 | Nov 5 |
| 🥬 Cauliflower | 88 | Dec 11 |

🌡️ Winter melon, Aubergine, Okra never accumulate enough heat outdoors in Melbourne — not in any month. Locally these need a greenhouse or a warm windowsill.
