While it is still very warm outside, houseplants need to begin the transition back into your home. Any that have spent the summer outdoors should be brought onto a porch or deck where they receive less daylight, a step to help them acclimate to the lower light level in your home. Plants that have been in contact with the ground should be repotted to ensure worms, ants or pests are not tagging along. Check for any obvious signs of insects on the leaves, stems and top of the soil. A strong spritz from the garden hose followed by spray of insecticidal soap can help to keep aphids, mites and others from causing problems indoors. Once you make the move indoors, don’t despair if your plants drop a few leaves. The drier air and lower light levels mean the plant cannot support all the summer foliage. Many plants will replace the leaves after they have adapted to their winter quarters.
