Sardinian Santolina problems — and how to fix them
Sardinian Santolina (Santolina insularis) 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.
Crown rot in winter wet
Despite its altitudinal range, this species is native to well-drained rocky habitats; in UK winters, ensure the planting site sheds water rapidly and consider a gravel collar around the crown.
Sparse flowering in shade or rich soil
Plants grown in even partial shade or in fertile, moisture-retentive soil produce weak stems and fewer flowerheads; move to a sunnier, leaner position and hold back on feeding.
