What Can You Plant in Pots for Fall?
From late summer, sow kale, spinach, lettuce, and carrots in pots; count back from your first frost and cover pots on cold nights.

Sow fall crops in 4 steps
- Find your first frost date. Look it up in our planting-date tool or the Almanac frost tables. Everything counts back from this one date.
- Count back with slack. Take each crop’s days from the table below and add two weeks of slack for cool soil and short days. That total is how many days before frost to sow.
- Sow at the right moment. For most people that lands in August; warm zones can sow into September. Sow into fresh mix — refresh the top half of summer pots first (see soil guide).
- Cover on cold nights. Drape fabric row cover over pots when frost threatens; it adds a few degrees. On hard-freeze nights, carry small pots inside. Covers pause frost, not deep winter.
Fall crops for pots, by sow timing
| Crop | Sow this far before first frost | Notes |
|---|---|---|
| Kale | 10–12 weeks | Takes light frost; sweetens after cold |
| Carrots | 10–12 weeks | Short round types suit pots |
| Spinach | 8–10 weeks | Germinates poorly in heat; shade the pot |
| Lettuce | 8 weeks | Cut-and-come-again into autumn |
| Radishes | 6–8 weeks | Fastest fallback if you start late |
| Garlic | Plant ~7 weeks before | Overwinters; harvest next summer |
Say you have three pots free in late August. Sow kale in one, spinach in one, lettuce in the third. All three take light frost — a rare case of cold improving lunch.
Quick answers
Is it too late to start fall crops?
Count back from your frost date. If fewer than 8 weeks remain, sow radishes and lettuce — the sprinters. Kale and carrots need the full window; save them for next year.
Can I reuse summer pots for fall?
Yes, with refresh: tip out the top half of mix, refill with fresh mix plus compost. If blight hit the summer crop, replace all the mix instead.
Row cover, old sheet, or plastic?
Fabric row cover first: it breathes and adds a few degrees. A sheet works in a pinch. Never lay plastic straight on leaves — it freezes them where it touches.
Should I feed fall crops?
Lightly. Growth slows as days shorten, so half the summer rate is plenty. The compost in fresh mix carries most of the load.
What about fall pests?
Pressure drops, but watch slugs under covers and aphids on kale. A strong water jet handles aphids; hand-pick slugs after dark.

Bottom line: count back from first frost with two weeks of slack, sow greens in August, and cover pots on frost nights. Fall is for greens, not summer fruit — skip peppers and basil now.
