Winter houseplant care

Water very sparingly. In winter, the potting mix should be dry on top and just moist (like a squeezed out sponge) beneath. Succulents and cacti should be kept practically dry. Shift tropical plants away from cold draughts. Find a warm part of the house where there is bright light but not direct sun. Move plants away from heaters and fires and away from direct sun. The sun is at a lower angle in winter. Raise the humidity around precious plants. Try placing them on a dish of stones filled with water so that the pot sits just above the water. Heaters create dry air. Wipe the dust from leaves with a damp cloth. Add spraying oil for extra shine and to kill scale insects (but don't use any oil on palms or ferns).
