ðą How to Care for Woolly Crassula to Prevent Mealybugs?
ð§ How to Water
Water thoroughly, then wait until the mix is completely dry before watering again, roughly every 10 days in the growing season and much less in winter. Constantly damp soil quickly causes root rot. Water the soil, not the hairy leaves, and never leave the pot standing in water.
âïļ Lighting
Bright light with a couple of hours of direct sun, preferably in the morning or evening. In its habitat it gets some shade from the midday sun and the leaves can scorch in intense afternoon light. In full sun the leaves turn reddish; in too little light the stems stretch and the plant loses its compact shape.
ðŠī Ideal Soil
Use a cactus and succulent mix with extra grit, coarse sand or perlite. Good drainage is essential, as the plant naturally grows in rock crevices and rots in heavy, wet soil.
