Mineral-Heavy Substrate: The root system requires maximum breathability. Use an ultra-porous mix consisting of 70% to 80% inorganic aggregates (pumice, perlite, lava rock, and coarse granite grit) and 20% to 30% sifted organic soil.
Blasting Sunlight: Place the plant in full, direct sun. Insufficient lighting causes weak, elongated, green trunk growth (etiolation) and ruins its tight, globose profile.
Soak-and-Dry Watering: During the spring and summer active growing season, water the plant thoroughly, but only when the potting mix is bone-dry all the way to the bottom. Adjust your schedule based on the weather—typically watering every 3 to 5 days in scorching summer weather.
