Arisaema speciosum problems — and how to fix them
Arisaema speciosum (Arisaema speciosum) 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.
Summer heat stress
From cool forests, it resents hot, humid summers and poor drainage. Give cool, shaded, sharply drained conditions.
Tuber rot in dormancy
Wet winter soil rots the resting tuber. Ensure free drainage or lift and store cool and barely moist.
Slug damage
Emerging shoots and the large leaf are prone to slug attack. Protect early growth with barriers or wildlife-safe deterrents.
Leaf scorch
Direct sun browns the broad leaf and ends the display early. Maintain dappled shade and steady moisture.
