Arisaema jacquemontii problems — and how to fix them
Arisaema jacquemontii (Arisaema jacquemontii) 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 on a well-drained site or raised bed and improve heavy ground with grit and leaf mould.
Late frost damage
Although hardy, emerging spring shoots can be nipped by late frosts. Mulch the crown and protect new growth on cold nights.
Slug and snail damage
Soft emerging shoots and leaves are grazed by slugs and snails. Use barriers or wildlife-safe controls as growth appears.
Leaf scorch
Too much hot, direct sun browns the leaf and dries the tuber. Site it in dappled or afternoon shade.
