Check these first

- Look for wilting on only one side of the plant.
- Test the soil for proper drainage.
Likely causes
Verticillium wilt
Most likelyHow to tell: The plant wilts suddenly, often starting on one side or one branch. The leaves may turn yellow or brown before dropping off.
What to do: There is no cure for this fungus. Prune out the affected branches to slow the spread, but keep tools sterilized with bleach between cuts.
Severe drought
PossibleHow to tell: The leaves look shriveled and the soil is bone dry and pulling away from the edges of the root zone. This usually happens during long heat waves.
What to do: Give the plant a deep, slow soak with 5 gallons of water. Mulch around the base to help the soil hold onto moisture in the future.

When to worry
If the wilting is sudden and affects only one branch, it is likely Verticillium wilt, which is fatal. If the whole plant droops during a heat wave, it likely just needs a drink.
Stopping it coming back
Plant your sumac in well draining soil and avoid wounding the roots during gardening, as this is how the wilt fungus enters.
