Winter Care for Houseplants Cuts Water and Boosts Humidity
Indoor plants need less water from December to March due to slower growth. Avoid overwatering to prevent root rot while increasing humidity by grouping plants or using water trays. Maintain 18 to 22 C day, 12 to 15 C night, relocate for light, rotate pots, repot in January or February, clean foliage, and pause fertilizing until mid March.
