Diluted low-nitrogen cactus fertilizer once every 2 months. Avoid high-nitrogen fertilizers to prevent weak, leggy stem growth
Eggshell powder topdressing：Crush baked, cooled eggshells into fine powder and sprinkle around the base of the plant; avoid direct contact with stems to prevent physical irritationPruning
- Remove dead, broken, or diseased stems in late spring after flowering to maintain plant form
- Trim overgrown branches to control height and spread; make clean cuts just above a spine node
- Avoid heavy pruning, as ocotillo regrows slowly and may take multiple seasons to recover
