Rotting Barrel Cactus: Low Survival Odds

Grim Reality

Barrel cactus (Echinocactus) with basal yellowing/shriveling rot. Once rot enters the main body, re-rooting almost never works.

Last-Ditch Attempt

1. Unpot; wash roots.
2. Cut away all brown/black tissue until only hard green remains.
3. Dust cuts with sulfur.
4. Lay on side in dry pumice (rot area exposed to air).
5. Wait months – may form adventitious roots on sides.

Success Rate: <5%

Barrels lack the ability to root from the main stem like columnar cacti. Energy reserves deplete before roots form.

Prevention Is Everything

• Winter: bone dry.
• Summer: water when dry, not on schedule.
• Gritty mineral soil.

Replace with a healthy specimen; learn from the loss.
