Echinopsis cv. Haku-Jo Maru

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 sparingly—every 15–20 days or when the soil is bone dry. Cactuses store water, so overwatering can harm them. Reduce watering further in winters.

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.
