Thick-stemmed Aichryson problems — and how to fix them
Thick-stemmed Aichryson (Aichryson pachycaulon) 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.
Root rot from overwatering
Sitting in wet soil causes rapid stem and root rot. Ensure the pot drains freely and water only when the top of the soil is dry. Terra-cotta pots help wick away excess moisture.
Premature monocarpic death
As a biennial, the plant is genetically programmed to flower and die. This is normal behaviour, not a disease. Collect seeds before the parent plant collapses to continue the line.
Aphids on flower stems
Soft-bodied aphids cluster on emerging flower stalks. Remove by hand or with a firm water spray, or apply diluted insecticidal soap, avoiding the delicate flowers.
