Pinnate Santolina problems — and how to fix them
Pinnate Santolina (Santolina pinnata) 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.
Root rot in wet soil
This species is especially sensitive to waterlogging; plant in raised beds or on slopes in heavier garden soils and ensure pots have large drainage holes.
Legginess and centre-splitting
Without an annual hard prune in early spring and a trim after flowering, plants become straggly and the centre collapses; prune back to low woody growth to reset the mound.
