I have noticed a lot of dust on my houseplants. What is the best way to clean them?
Clean leaves of smooth, large-leaved plants such as philodendron, ficus and dracaena with a soft, damp cloth to gently wash off any accumulation of dust and grime during the winter months. For smaller leaved plants, occasional misting with water will cleanse the leaves. You can also use a clean feather duster for this purpose.
