When to Bring Potted Patio Plants Indoors
Pots cool faster than garden beds. Tender annuals and frost-tender patio plants need to move when nights approach 50F or before the first freeze. Hardy herbs and cold-tolerant greens can stay outdoors longer with mulch or cover.
Confirm your date on first frost date. Use Overwinter Indoors for the herb split and pot-up checklist.
Temperature Triggers
| Plant type | Move indoors when | Notes |
|---|---|---|
| Basil and tender annuals | Nights near 50F | Do not wait for 32F if you want living plants |
| Peppers, tomatoes in pots | Before hard frost | Pick ripe fruit first; overwinter peppers only if healthy |
| Tender perennials (marjoram, some salvias) | Before hard frost north of mild zones | Treat as annuals outdoors if you skip the move |
| Rosemary in cold zones | Before hard frost | Outdoor hardy about zones 8 to 10 |
| Hardy culinary herbs | Usually leave outdoors | Mulch and sharp drainage matter more than a warm room |
| Cool greens in pots | Optional cover outdoors | See Season Extension for fabric and frames |
Extension frost guidance separates light frost near 32F from hard freezes in the mid to upper 20s F. Tender crops fail at light frost. Act on your forecast.
Patio Pot Checklist
- Sort pots: bring indoors, cover outdoors, or leave hardy.
- Pick usable fruit and leaves from tender crops on the Frost Harvest Desk.
- Hose and inspect for pests before any plant enters the house: pest check guide.
- Quarantine new indoor plants about a week.
- Place pots in bright windows and adjust water for shorter days: windowsill herb care.
What Can Stay Outside
- Hardy herbs in their zone range with light mulch and pots that drain.
- Cold-hardy greens under row cover or in a cold frame when you want a longer harvest.
- Empty or stored pots tipped on their side so they do not crack from freeze-thaw water.
For outdoor cover methods and degree gains, open the Season Extension Desk. For bed closeout tasks, use Garden to Bed.
Peppers and Other Tender Crops
Peppers can overwinter as potted plants under bright light. Steps are in how to overwinter peppers indoors. Many gardeners still prefer fresh pepper seeds in spring on the seed-start calendar.
Next Steps
- Set zone and frost on Overwinter Indoors.
- Cover hardy outdoor beds on Season Extension if you want weeks more harvest.
- Hand off indoor water and light to Houseplants.
