Troubleshooting
Skimmia japonica Rubella problems — and how to fix them
Skimmia japonica Rubella (Skimmia japonica 'Rubella') 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.
Leaf yellowing (chlorosis)
Lime-induced iron/manganese lock-out on alkaline soil; correct with ericaceous compost or chelated iron and acidify the root zone.
Leaf scorch
Brown, crispy margins from too much sun or cold drying winds; move to deeper shade and shelter from exposure.
No berries
This is a male cultivar and never fruits; it is grown for buds and as a pollinator for female skimmias like 'Veitchii'.
Root rot in pots
Sodden, poorly drained compost rots the shallow roots; use a free-draining ericaceous mix and never leave the pot standing in water.
