How to Grow and Care
If you can successfully grow other globular cactus, you can most likely grow Echinocereus well. One of the key factors in success with these is avoiding any hint of wet soil. Because their root systems are weak, they are especially prone to root rot, which will eventually kill your plant. Otherwise, they thrive on a program of strong, bright light; slight water; and a steady diet of light fertilizer.
Echinocereus is vulnerable to mealybugs and aphids. Echinocereus are slow growing cactus that should only need repotting every other year or so. You can prolong the time to repotting by removing plantlets and potting them up in their own pots. When repotting a cactus, carefully remove it from its pot and knock away any clumped soil. These plants tend to be shallow-rooted with weak root systems, so take care not to damage their roots… – See more at: How to Grow and Care for Echinocereus.
