Moving Tropical Plants Indoors for Winter

By Marcus Williams · October 1, 2026

When to Bring Tropicals Inside

Most tropical plants need to move indoors when nighttime temperatures consistently drop below 55F. For most regions, this means early to mid-October. Waiting too long risks cold damage that can set plants back months.

Pre-Move Inspection

Before bringing any plant inside, inspect it thoroughly for pests. Check the undersides of leaves for spider mites, mealybugs, and aphids. Treat infestations outdoors with insecticidal soap at least two weeks before moving plants inside.

Quarantine Protocol

Isolate new arrivals for 2 weeks from existing indoor plants
Check soil surface for fungus gnats and ants
Rinse foliage with a gentle spray to dislodge hidden pests
Repot if root-bound or if soil is old and compacted

Acclimation Strategy

Indoor light levels are dramatically lower than outdoor light. Move plants gradually over 1-2 weeks. Start by placing them in a shaded outdoor spot, then move to a bright indoor location near a south-facing window.

Humidity Management

Indoor heating drops humidity to 20-30%, while tropical plants prefer 50-70%. Group plants together to create a microclimate, use pebble trays with water, or invest in a humidifier. Misting alone is not sufficient for most tropicals.

Watering Adjustments

Reduce watering frequency by 30-50% compared to summer. Tropical plants grow slower in lower light and cooler indoor temperatures. Always check soil moisture before watering rather than following a fixed schedule.
