Wisley Pearl Gaultheria problems — and how to fix them
Wisley Pearl Gaultheria (Gaultheria × wisleyensis 'Wisley Pearl') is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor berry set without male pollinator
Plants are effectively dioecious; female plants bear berries only when a compatible male Gaultheria (e.g., G. mucronata male or another wisleyensis male clone) grows within pollination range. Plant at least one male alongside female plants.
Suckering and invasive spread
The plant produces underground suckers and can spread aggressively; sever and remove suckers annually with a spade to prevent it colonising neighbouring plants.
