Leucanthemum × superbum 'Silver Princess' problems — and how to fix them
Leucanthemum × superbum 'Silver Princess' (Leucanthemum × superbum 'Silver Princess') 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.
Crown rot in wet soil
Poor winter drainage rots the crown. Plant in free-draining soil or raised ground, and avoid mulching directly over the crown.
Powdery mildew
A white coating develops in humid, crowded plantings. Space generously, improve airflow and remove infected leaves to slow spread.
Declining vigour
Compact dwarf daisies can exhaust themselves and need lifting and dividing every 2-3 years to keep flowering freely.
Slugs and snails on new growth
Tender spring shoots are grazed by slugs and snails. Use barriers, traps or wildlife-safe controls early in the season.
