Houseplant Care in June
Water more often as soil dries faster, fertilize established plants once or twice a month, and treat pests early. Mid-summer is when neglect catches up fast.
Light in June
The sun is at its highest angle of the year. Sensitive species can scorch in a hot south or west window; a sheer curtain cuts the light (Iowa State Extension).
Watering in June
Soil dries fastest now. Check the soil instead of watering on a schedule: Iowa State Extension says to water when the soil is dry to the touch down an inch or so, and to fertilize most houseplants once or twice a month in the growing season.
Pests and problems to watch in June
Spider mites favor dry air (UC IPM), so watch plants in air-conditioned rooms. Check plants summering outdoors for thrips and whiteflies.
What to plan now
Summer is still active growth, and Clemson HGIC advises repotting only as needed during spring and summer while the plant is actively growing. Finish major repots before growth slows in fall.
