Question from a blogger: Do you need to fertilize houseplants in winter?
Indoor flowering plants thrive with fertilization from March to September, or whenever they're blooming. This applies to favorites like azaleas, cyclamen, poinsettias, Saintpaulias, and kalanchoes that brighten our homes. Orchids require a specific, well-balanced fertilizer tailored to their needs. Don't overlook bulbous plants such as narcissus, daffodils, tulips, and amaryllis—give them a diluted fertilizer solution even after flowering, as long as leaves remain green, to replenish their bulbs as energy reserves.
Most green houseplants, originating from tropical or subtropical regions, grow year-round without a true dormant period. However, our winter's shorter days reduce their vigor and growth. Skip fertilization from October through February to avoid stressing them.
For cacti, adopt an even stricter approach: withhold water entirely during the three winter months. This rest period promotes robust summer growth and flowering.
That said, all houseplants can suffer from low humidity—dry indoor air is a common culprit. Mist the foliage regularly for relief, but avoid wetting the flowers to prevent damage.
Pro Tip: Never use leaf shine sprays on flowering plants, as they can harm delicate blooms.
