Troubleshooting
Sweet Box problems — and how to fix them
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.
Slow establishment
Plants can sit and sulk for a season after planting; keep moist and mulched and growth accelerates once roots take hold.
Unwanted suckering
It spreads by underground runners and can outgrow its space; dig out or sever suckers to keep clumps contained.
Leaf yellowing
Chlorotic foliage usually signals waterlogging or very poor, compacted soil; improve drainage and add organic matter.
Sparse flowering
Too much sun and dryness reduce the fragrant winter bloom; site in cooler shade with consistent moisture.
