Water thoroughly when the top 5–7 cm of soil is completely dry; reduce frequency during extreme heat

Fertilization

Diluted low-nitrogen succulent fertilizer once every 6 weeks. Fertilizer should be diluted to half the recommended strength to avoid burning succulent roots

Eggshell powder topdress:Crush fully dried eggshells into a fine powder; sprinkle a thin layer on the soil surface to improve drainage and provide calcium for healthy stem growth
Pruning
