Winterberry Holly 'Winter Red' problems — and how to fix them
Winterberry Holly 'Winter Red' (Ilex verticillata 'Winter Red') 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.
No berries
'Winter Red' is female and needs a compatible early/mid-season male such as 'Southern Gentleman' within about 15 m to set its heavy fruit display.
Iron chlorosis
Yellow leaves with green veins on alkaline soil. This species is especially pH-sensitive; acidify the soil and apply chelated iron to green it up.
Drought leaf drop
As a moisture-lover it sheds leaves and aborts berries if the soil dries out. Plant in a damp spot or irrigate, and mulch heavily to hold moisture.
Birds stripping berries
Wildlife is a benefit, but birds can clear berries early. For long winter display, choose a sheltered spot and accept some loss as the trade-off.
