Vasey's Trillium problems — and how to fix them
Vasey's Trillium (Trillium vaseyi) 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.
Slug damage in spring
Emerging shoots and large leaves are highly palatable to slugs; damage can be severe in wet springs. Apply iron-phosphate slug controls as soon as growth emerges and maintain them through flowering for best results.
Deer browsing
Vasey's trillium is browsed by deer, particularly the flowers and buds in spring. In deer-prone gardens, apply deer-repellent spray to emerging growth and consider temporary exclusion netting around plants at flowering time.
