Frequently Asked Questions
Why does my echinocactus have Corking?
Cause: Barrel cacti (Echinocactus and Ferocactus species) develop characteristic basal corking as they mature, forming a woody 'foot' at the soil line. This periderm development begins when plants reach 8-12cm in diameter and serves dual functions: structural support for the heavy water-filled stem and protection against soil-borne pathogens. Unlike columnar cacti, barrel cacti typically show limited upward progression of corking—the brown tissue remains concentrated at the base, covering no more than the bottom 10-20% of the ribbed body.
Solution: Identify species: Golden barrel (Echinocactus grusonii) and similar barrel types naturally cork at base
Prevention: Provide excellent drainage to prevent rot that can mimic or accompany corking. Avoid overwatering which can cause basal rot disguised as corking.
