Troubleshooting
Digyna Sweet Box problems — and how to fix them
Digyna Sweet Box (Sarcococca hookeriana var. digyna) 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 in waterlogged soil
Wilting and yellowing in poorly drained spots; improve drainage by incorporating grit or raising the planting level.
Scale insects
Waxy brown bumps on stems and undersides of leaves; treat with horticultural oil in late winter.
Slugs and snails
Young shoots can be damaged in early spring; use iron phosphate pellets or a copper barrier around vulnerable plants.
Sparse flowering
Usually caused by overly sunny, dry conditions. Move to a shadier spot with better moisture retention.
Frost damage to flower buds
Flowers in midwinter and can be caught by sharp frost; damage is usually cosmetic and new growth recovers.
