🗓️ This month sits inside the frost-free window. Average last spring frost around Feb 16, first autumn frost around Dec 12 — roughly 300 frost-free days. Sow tender crops after the last frost date and make sure they finish before the first.

Sow this month — when would you harvest?
Assuming you sow in mid-September, then adding up the warmth Wuhan usually gets, one day at a time — which is why some of these run past the end of the month.
| Crop | Days | Harvest around |
|---|---|---|
| 🏵️ Marigold | 41 | Oct 25 |
| 🌿 Amaranth greens | 49 | Nov 2 |
| 🌱 Microgreens | 5 | Sep 19 |
| 🥢 Green Beans | 56 | Nov 9 |
⏳ Too late this month: Tomato, Chili Pepper, Edamame, Pumpkin, Sunflower, Aubergine, Winter melon, Okra would still be in the ground when the first frost arrives (around Dec 12). Sow them earlier in the year, or grow them under cover.
