Troubleshooting
Little Sweet Betsy problems — and how to fix them
Little 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
Newly emerging foliage and flower buds in late winter and early spring are attractive to slugs. Protect with iron phosphate pellets applied around the emerging shoots before damage begins. Avoid overhead evening watering, which worsens slug activity.
Non-flowering after disturbance
Like all Trilliums, Little Sweet Betsy dislikes root disturbance and may fail to flower for one to two seasons after transplanting. Plant rhizomes at 5 cm depth in autumn and leave them undisturbed for several years before any division is attempted.
Rhizome rot in poorly drained soil
Waterlogged or compacted soil causes rapid rhizome rot. Ensure the planting site has free drainage and incorporate abundant organic matter to create a moisture-retentive but aerated growing medium.
