🌱 How to Care for Crassula erosula to Prevent Mealybugs?

💧 How to Water

Water thoroughly, then wait until the soil is completely dry before watering again; in the growing season that is often every 7 to 10 days in a pot, much less when the plant is resting. The wild form grows mainly in the cool season, so cut back watering in the hottest weeks and in cold, dark spells. Empty saucers after watering: standing water quickly causes root rot. Sudden swings between very dry and very wet can cause corky blisters (edema) on the leaves.

☀️ Lighting

Full sun or the brightest window you have. Strong light keeps the plant compact and brings out red tones in the leaves; in shade the leaves stay green and the stems stretch and flop. Indoors a south- or west-facing window is best, and indoor artificial light alone is usually not enough.

🪴 Ideal Soil

Use a sandy, gritty succulent or cactus mix, for example regular potting soil mixed with plenty of coarse sand, perlite or pumice. The key is fast drainage; poor, mineral soil suits it better than rich compost.
