As fall approaches, it’s time to plan for bringing cold-sensitive plants indoors, according to Kansas State University horticulture expert Cynthia Domenghini.
Gardeners who moved houseplants outside for the summer should prepare for their return to indoor conditions. Begin by inspecting plants for pests like mites and aphids. Remove pests by spraying foliage with water or soaking the container in lukewarm water for 15 minutes. Discard any plants with severe infestations.
Once inside, monitor plants for pests and adjust care as growth slows. Water plants only when the soil surface is dry, and reduce fertilization until spring. Gradually acclimate plants to lower indoor light by moving them closer to windows initially, then further away over several weeks. Use grow lights if needed and avoid exposing plants to cold drafts or direct heat from vents.
Since many houseplants thrive in humid conditions, placing them in more humid areas like kitchens or bathrooms can be beneficial. Grouping plants together can also help create a favorable microclimate.
