Move Tropical Plants Indoors: Fall Guide

By Marcus Williams · September 29, 2026

When to Bring Tropicals Inside

Most tropical houseplants should move indoors before nighttime temperatures consistently drop below 55°F (13°C). In most temperate zones, this means bringing plants inside by early to mid-October. Waiting too long exposes plants to cold stress that can cause leaf drop and slowed growth.

The Two-Week Transition Method

Sudden environmental changes shock tropical plants. Instead of moving them directly from outdoor sun to indoor shade, use a gradual two-week transition. Start by moving plants to a shaded porch or garage for one week, then bring them to their final indoor location. This mimics the gradual light reduction of natural seasons.

Pre-Move Pest Inspection

Before bringing any plant indoors, inspect it thoroughly for pests. Check leaf undersides for spider mites, aphids, and scale insects. Treat with insecticidal soap or neem oil at least one week before the move. This prevents introducing outdoor pests to your indoor plant collection.

What to Look For

Fine webbing between leaves (spider mites)
Sticky residue on leaves (aphids or scale)
Small brown bumps that scrape off (scale insects)
Tiny flies around the soil surface (fungus gnats)

Adjusting Water and Light Indoors

Indoor conditions are drier and darker than outdoors. Water tropicals when the top inch of soil feels dry, which may be more frequent than outdoors due to heating systems drying the air. Place plants near south or west-facing windows for maximum light. Consider supplemental grow lights for light-hungry species like bird of paradise and banana plants.

Humidity Solutions for Winter

Central heating drops indoor humidity to 20-30%, far below the 50-70% most tropicals prefer. Group plants together to create a microclimate, place pebble trays with water beneath pots, or run a humidifier in the plant room. Misting provides only temporary humidity and is less effective than these methods.
