Astrophytum capricorne
Care and Growing
The Goat’s Horn is a hardy, slow-growing cactus that is highly sought after by collectors for its rugged, "ancient" look.
Light Needs: Prefers Full Sun to Very Bright Light. To maintain its dense white flocking and ensure regular blooming, it needs plenty of direct sunlight. However, in extremely hot climates, some afternoon filtered light can prevent the body from scorching.
Water Needs: Low. Like most Astrophytum, it is sensitive to overwatering. Follow a strict "soak and dry" cycle. During its winter dormancy, watering should be stopped completely to prevent root and body rot.
Soil Needs: Requires Mineral-Rich, Gritty Soil. It thrives in a mix that is heavy on pumice, lava rock, or coarse sand with very little organic matter. A slightly alkaline soil (adding a bit of limestone) mimics its natural habitat.
Temperature & Hardiness: Relatively cold-hardy for a cactus, it can tolerate brief dips down to 20°F (-7°C) if kept bone-dry, but it is best protected from hard freezes.
