Indoor Plant Fall and Winter Checklist

Preparing Houseplants for the Dark Months

As days shorten and heating systems kick on, indoor plants face a challenging transition. Lower light levels, drier air, and cooler window temperatures all affect plant health.

Step 1: Clean and Inspect

Wipe every leaf with a damp cloth to remove dust. Inspect both sides of leaves and stem junctions for pests: webbing, sticky residue, or unusual bumps. Treat problems now before moving plants together for winter.

Step 2: Relocate for Light

Move plants closer to windows as sun angle drops. South and west-facing windows receive the most winter light. Consider adding a grow light for plants showing stretched stems, small new leaves, or faded variegation.

Step 3: Reduce Watering

Most houseplants slow growth in fall and winter. Check soil moisture by inserting a finger two inches deep. If damp, wait. Keep roots slightly moist, never soggy.

Step 4: Increase Humidity

Heating drops indoor humidity to 20-30 percent. Group plants together, use pebble trays with water, or run a cool-mist humidifier. Bathrooms provide naturally higher humidity.

Step 5: Stop Fertilizing

Suspend fertilizer from October through February. Plants cannot use nutrients during dormancy. Excess salts accumulate and burn roots. Resume in early spring when new growth appears.

Step 6: Protect from Drafts

Move plants away from cold windows and drafty doors. Tropical plants within two feet of single-pane windows can suffer cold damage on winter nights.

Step 7: Plan for Spring

Note which plants thrived and which struggled. List plants to propagate, new varieties to try, and supplies needed. Order grow lights before spring sellouts.
