Troubleshooting
Wildfire Black Tupelo problems — and how to fix them
Wildfire Black Tupelo (Nyssa sylvatica 'Wildfire') 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.
Difficult transplanting / transplant shock
Black tupelo has a deep, fleshy taproot and resents disturbance. Always plant container-grown or young balled-and-burlapped stock in early spring; water carefully for 2–3 seasons. Never attempt to move established trees.
Leaf spots and twig cankers
Several fungal pathogens (Cercospora, Botryosphaeria) cause leaf spots or dieback in wet seasons. Prune out affected branches, improve air circulation, and avoid overhead watering. Generally not life-threatening to established trees.
Scale insects on branches
Oystershell scale and other armored scales can infest branches, causing dieback. Apply horticultural oil in late winter/early spring when crawlers are active. Prune heavily infested branches.
