If your echeverias and prickly pears keep developing black rot despite your best efforts, this disease-shielding mix is your secret weapon. The key lies in a fast-draining blend of 80% coco coir, pumice, and crushed eggshells—where neem oil doesn’t just sit on the surface but actually vaporizes during watering to sterilize soil pores.

Start by mixing one part pumice (for aeration) and one part crushed eggshells (for calcium and grit) with four parts coco coir. Add 1 teaspoon of neem oil per gallon of mix and let it cure for 24 hours before planting. Water deeply but infrequently—this blend thrives on drought-like conditions—and watch as fungal threats evaporate with each irrigation. The eggshells also release calcium slowly, strengthening cell walls against rot.
