Troubleshooting
Sweet Betsy problems — and how to fix them
Sweet Betsy (Trillium cuneatum) 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.
Slugs and snails
New spring growth is highly attractive to slugs. Protect emerging foliage with iron phosphate pellets or copper barriers. Overhead watering in the evening worsens slug pressure.
Root rot in poorly drained soils
Rhizomes rot rapidly in waterlogged conditions. Ensure planting site drains freely and avoid depressions where water collects. Raised woodland beds with deep organic matter prevent this problem.
Transplant shock and non-flowering
Like all Trilliums, Sweet Betsy dislikes disturbance. Freshly moved plants may not flower for 1–2 seasons. Purchase nursery-grown stock only; never collect from wild populations.
