Maple Tree Failing to Leaf Out: Assessing Winter Injury

Brown Leaves Persist, No Buds in Spring

A maple that had leaf spots last year (diagnosed as possible anthracnose) now holds brown, curled leaves from last fall with no new buds while other trees are leafing out. Scratched twigs show green underneath.

Expert Follow-Up

Steve initially suspected anthracnose, but the follow-up reveals leaves turned reddish-brown without blackening, and winter was warm and dry. He suggests the browning may be from heat/drought stress. Since twigs are green, he advises waiting longer for bud break.

Next Steps

• Scratch more twigs to confirm green tissue.
• Check trunk for loose or damaged bark.
• Send a photo of affected branches if unsure.
• Consult a local nursery or city arborist for on-site diagnosis.

Caution

Diagnosis by email is challenging; professional inspection is best.
