Troubleshooting
Coppertone Stonecrop problems — and how to fix them
Coppertone Stonecrop (Sedum nussbaumerianum) 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.
Etiolation (stretching) and loss of color
In too little light the rosettes stretch, gaps open between leaves and the copper tone fades to green. Move to brighter, more direct sun and the color returns over time.
Root and stem rot from overwatering
The most common killer. Soggy or poorly drained soil causes mushy, blackening stems. Use gritty mix and a drainage hole, and only water once the soil is fully dry.
Mealybugs
White, cottony pests hide in leaf joints and rosette centers. Spot-treat with 70% isopropyl alcohol on a cotton swab or insecticidal soap, and isolate affected plants.
Leaf drop from handling or stress
Leaves detach easily when the plant is moved or knocked. This is normal for the species; dropped healthy leaves can be used to propagate new plants.
Sunburn during abrupt light increases
Plants moved suddenly from low light into intense sun can scorch, leaving pale or brown patches. Acclimate gradually over a week or two.
Frost damage
Not cold-hardy below about 30 F (-1 C); frost turns tissue translucent and mushy. Bring indoors before cold snaps in zones below 10.
