How can I take care of my houseplants during the cooler weather and lower light conditions of autumn?
Place them where they can receive adequate light in your home; supplemental lighting may be necessary. As growth slows down, or even stops in some cases, do not fertilize again until early spring (except for orchids, African violets and certain other winter-blooming houseplants). Provide humidity by placing plants on a saucer and then on a tray of pebbles that are kept constantly moist. Water less frequently, but water deeply at each watering.
Keep leaves free of dust by misting them and wiping them with a soft, moistened cloth. Check frequently for insects, remove them manually and apply insecticidal soap as needed. Every few months, cover the base of the plant and wash it down with a warm shower in the bathtub.
