The bed you were about to put to sleep has one more crop in it.
Maybe two.
Root crops and bulbs don't care that the calendar says fall. They care that the ground is cooling, and cooling ground is where they do their best work.
Some of these harvest before winter. Some sit in the soil through the cold and come out sweeter in March, because frost turns their starch to sugar.
🥕 Nine to plant in September:
- Garlic – Cloves go in pointed end up, about 2 inches deep. They root through fall, sleep through winter, and come up ahead of nearly everything in spring. Harvest in July.
- Shallots – Sets 1 inch deep. Each one splits into a cluster of four to eight by June. The easiest allium to grow, and one of the priciest to buy.
- Onion sets – Pull as scallions in a month or two, or leave them through winter for bulbs. In Zones 3–6, fall sets are for scallions only.
- Winter radishes – Not the spring kind. Daikon, Black Spanish, watermelon radish need cooling soil to size up, and they store for months.
- Beets – Greens at 30 days, roots around 55. A light frost pushes the roots sweeter. Zones 3–6, sow this week and cover.
- Turnips – Cool soil makes them denser and less bitter than spring ones. Pull at golf-ball size, and eat the greens too.
- Rutabaga – Needs a full 90 days, so this is a Zones 6–8 September crop. Keeps in a cold garage for months.
- Carrots – Zones 7–10 can sow now. In colder zones, summer carrots stay in the bed under 6 inches of straw and get dug in March, sweeter than anything pulled in July.
- Parsnips – Already in the ground. The September job is leaving them there. Hard frost is what makes them worth eating.
The season isn't ending. It just moved underground. 🌱
