Troubleshooting
Chinese Premna problems — and how to fix them
Chinese Premna (Premna microphylla) 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.
Cold damage
Premna is frost-tender; temperatures near or below 5°C can damage or kill it, so bring it under cover well before frost.
Leggy growth in low light
Insufficient light, especially indoors, stretches shoots and enlarges leaves; provide the brightest position or supplement with a grow light.
Spider mites indoors
Dry indoor air encourages mites that stipple and bronze foliage; raise humidity and rinse or treat the canopy at the first sign.
Root rot from overwatering
Soggy, poorly draining soil rots the roots; use a free-draining mix and let the surface dry slightly between waterings when growth is slow.
