Troubleshooting
Bear Tupelo problems — and how to fix them
Bear Tupelo (Nyssa ursina) 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.
Transplant shock
Nyssa has a deep taproot and resents root disturbance. Always plant container-grown specimens in early spring; avoid moving established trees. Mulch heavily to conserve moisture during establishment.
Leaf scorch in dry conditions
In periods of drought or on free-draining soils, leaf edges brown and scorch. Increase irrigation frequency and apply a deep organic mulch (10 cm) to retain soil moisture around the root zone.
Iron chlorosis on alkaline soils
Yellowing between leaf veins (interveinal chlorosis) occurs when soil pH rises above 6.5. Acidify with elemental sulphur or use chelated iron foliar spray; recheck soil pH annually.
