Troubleshooting
Arisaema serratum problems — and how to fix them
Arisaema serratum (Arisaema serratum) 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.
Tuber rot
Cold, waterlogged winter soil rots the dormant tuber. Plant in well-drained ground or a raised bed and improve heavy soil with grit and leaf mould.
Slug and snail damage
Emerging shoots and soft leaves are favourite targets. Protect new growth in spring with barriers or wildlife-safe controls.
Late frost damage
Spring shoots can be caught by late frosts despite the plant's hardiness. Mulch the crown and shield emerging growth on frosty nights.
Leaf scorch
Hot, direct sun browns and crisps the foliage. Grow in dappled or afternoon shade in cool, moist soil.
