Arizona Chalk Dudleya problems — and how to fix them
Arizona Chalk Dudleya (Dudleya pulverulenta subsp. arizonica) 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 summer watering
Watering during summer dormancy is the most common cause of failure. Resist all urge to water when the plant appears shrivelled in summer — this is normal dormancy behaviour.
Aphid infestations on flower stalks
Aphids target the flower stalks in spring. Remove by hand or with a diluted insecticidal soap spray; avoid directing the spray into the rosette or disturbing the farina.
Farina damage
The white powder is a non-renewable wax coating — once smeared or removed by touching, it does not regenerate on affected leaves. Always handle by the container, never the leaves.
