Houseplant Care in April
Move established plants to full-strength fertilizer, applied once or twice a month. Take cuttings while plants are actively growing. Repot any plant you missed in March.
Light in April
Light keeps getting stronger. Pull sun-sensitive species back from windows if leaves bleach. Iowa State Extension notes that south- and east-facing windows often give the most light, and that west-facing light may be too intense for some species.
Watering in April
Plants use more water as they grow. Check each pot and water when the top inch feels dry (UMN Extension) rather than watering everything on the same day. For established plants, Iowa State Extension advises fertilizing most houseplants once or twice a month in the growing season.
Pests and problems to watch in April
Thrips and aphids feed on soft new growth. UC IPM advises checking for aphids at least twice a week while plants grow rapidly. Check stems and leaf undersides for mealybugs and scale too.
What to plan now
Illinois Extension notes that stem cuttings are usually taken when a plant is actively growing in spring or summer. Order cuttings or new plants now so they settle in during the growing season.
