Houseplant Care in November
Don’t fertilize. Cluster humidity-loving species. Run a humidifier. Check leaf undersides regularly for spider mites.
Light in November
Days keep shortening toward the December solstice. Grow lights help species that need medium or high light; University of Missouri Extension puts medium-light plants at 250 to 1,000 foot-candles.
Watering in November
Water less often than in summer (Iowa State Extension). Drought-tolerant species need very little: NC State Extension advises watering snake plant only every one to two months in winter.
Pests and problems to watch in November
Heated air is dry: Illinois Extension notes that most homes have less than 30% humidity in winter, and dry air favors spider mites (UC IPM). Check leaf undersides regularly; Iowa State Extension advises dealing with mites early, while populations are small.
What to plan now
Holiday plant gifts (poinsettia, Christmas cactus, amaryllis) need bright light — plan a spot before they arrive.
