Echinocereus engelmannii problems — and how to fix them
Echinocereus engelmannii (Echinocereus engelmannii) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to bloom
Caused by inadequate sun or a warm, wet winter. Provide maximum light and a genuinely cool, dry rest period to initiate buds.
Root and basal rot
Soft, discoloured base or collapse from overwatering or cold-wet soil. Improve drainage, cut out affected tissue, and water far less, especially when cool.
Etiolated stems
Thin, pale, elongated growth from light starvation. Relocate to the brightest available position and increase exposure slowly.
Mealybugs
White cottony clusters in spine areoles and at the base. Spot-treat with 70% isopropyl alcohol on a cotton bud and check the roots for soil mealybugs.
