🌱 How to Care for Cholla to Prevent Scale Insects?

💧 How to Water

Water deeply until water runs out of the drainage holes, then let the soil dry out completely before watering again: roughly every 1-3 weeks in spring and summer depending on heat. In autumn and winter cut back to once every 4-6 weeks, or stop entirely for plants kept cool. Never leave it standing in water; soft, yellowing or mushy stems are the classic sign of overwatering and root rot.

☀️ Lighting

Chollas need strong light: full sun outdoors, ideally 6-7 hours of direct sun a day. Indoors place it in the sunniest south- or west-facing window. In very hot climates, a little afternoon shade prevents sunburn, and plants moved from indoors to outdoors should be acclimatised gradually.

🪴 Ideal Soil

Use a gritty cactus and succulent mix, or improve ordinary soil with plenty of coarse sand, grit or pumice. It tolerates acidic, neutral and alkaline soils as long as drainage is excellent. Outdoors, plant in a raised or sloping spot where water never pools.
