Troubleshooting
Ruby Necklace problems — and how to fix them
Ruby Necklace (Othonna capensis) 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.
Mushy, translucent stems / root rot
The most common problem, caused by overwatering or soil that holds moisture. Let the mix dry out fully between waterings, use a gritty fast-draining medium and a pot with drainage holes, and cut back hard on water in winter.
Leggy, stretched stems with green (not red) leaves
A sign of too little light (etiolation). Move it to the brightest window or add a grow light. Stronger light tightens growth and brings out the signature ruby-purple colour.
Shrivelled, deflating leaves
Usually underwatering or roots damaged by previous rot. If the soil is bone dry, give a thorough soak; if it has stayed wet, check the roots for rot instead of adding more water.
Loss of red colour
Stems revert to plain green in low light or with too much fertiliser. The red is a mild stress response, so brighter light, cooler nights and lean feeding restore it.
Mealybugs and aphids
Cottony white tufts in leaf joints (mealybugs) or clusters on new growth and flower stalks (aphids). Wipe off with a cotton bud dipped in isopropyl alcohol or treat with insecticidal soap, and isolate the plant until clear.
Bare, sparse stems over time
Older trailing stems naturally drop lower leaves and look thin. Trim them back to encourage bushier branching and replant the cuttings into the same pot to fill it out.
