Troubleshooting
Oregon Stonecrop problems — and how to fix them
Oregon Stonecrop (Sedum oreganum) 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
The most common failure mode indoors. Use well-draining compost, pots with drainage holes, and allow the compost to partially dry before the next watering. Reduce watering substantially in winter.
Loss of red colouring
The attractive red stress colouration fades in low light or with frequent watering and feeding. Increase light exposure and reduce feeding to restore colour. Cold temperatures also enhance reddening.
Aphids in spring
Soft new spring growth can attract aphids, particularly on outdoor plants. Knock off with a jet of water or apply dilute insecticidal soap solution. Avoid broad-spectrum pesticides that harm pollinators.
