Gymnocalycium Horstii

This plant thrives in full sun, meaning it requires at least 6–8 hours of direct sunlight daily. Ideal locations include south- or west-facing balconies, terraces, open gardens, or window sills that receive strong sunlight for most of the day.

Water only when the soil is completely dry .Usually every 10–15 days. Avoid waterlogging, as succulents are prone to root rot. Use pots with good drainage.

30–40% Coarse Sand: Ensures fast drainage and prevents water retention.
20–30% Perlite/Pumice: Improves aeration and keeps the mix light.
20–30% Crushed Brick/Granules: Adds structure and mimics native arid soils.
10–20% Leaf Compost (well-decomposed): Provides minimal organic nutrition.

Optional: A handful of horticultural charcoal to prevent rot and absorb impurities.This gritty, well-draining mix is perfect for preventing root rot and supporting healthy, compact growth in India's warm and dry to humid climates.
