7 Secrets to Overwintering Tropical Plants Indoors

1. Store Smart

Cut back potted tropicals by one-third and overwinter in a cool, low-light basement. Expert Michael Walek stores dahlia tubers in loose plastic bags or pots them up early to save spring time. Exception: bananas prefer normal household light and temperature—treat them as houseplants.

2. Light Right

Standard hardware-store grow lights work perfectly for light-hungry tropicals.

3. Watch the Forecast

Move plants indoors before the first frost; most dislike nights below 40–50°F. If you’re late, no panic—just avoid actual frost. For cannas and other bulbs, wait until frost kills foliage, then dig and store.

Find your average first frost date.

4. Bug Off

Rinse foliage thoroughly with a garden hose before bringing plants in. For infestations, use organic insecticidal soap. Any indoor pests usually disappear once plants return outside.

5. Water Wisely

Water about once a week. Walek also roots cuttings in water over winter for spring planting.

6. Dig It

Lift in-ground tropicals and pot them in basic plastic containers for winter storage.

7. Take It Easy in Spring

Don’t rush plants back into full sun. Harden them off under a tree or on a shady porch for a week or two to prevent leaf scorch.
