Troubleshooting
Spanish Stonecrop problems — and how to fix them
Spanish Stonecrop (Sedum hispanicum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown and stem rot (Botrytis / Pythium) in wet conditions
The most frequent problem, especially in poorly drained soils or prolonged wet weather. Improve drainage, space plants to allow airflow, and avoid overhead irrigation. Remove and discard severely affected sections; do not compost diseased material.
Slugs and snails
Slugs and snails feed on the succulent stems and leaves of outdoor plantings, leaving irregular holes and silvery slime trails. Encourage natural predators such as ground beetles, apply copper barrier tape around containers, or use nematode-based slug control (Phasmarhabditis hermaphrodita) in spring and autumn.
