If there are any leaves left, theyâll be wilted, curled and brown. Wilting develops due to a combination of physical blockage of the xylem vessels as a result of fungal growth, and the effect of fungal toxins that are carried upwards in the water stream.

This precludes the possibility of sun and frost causing the damage. Trees that grow with a compromised root system will have limited water availability and may send the wrong signals to foliage, creating off-season coloration. Learn more below. The leaves are broad and flat with sharp uneven edges. Anthracnose causes the wilting, withering, and dying of tissues. Frost damage is nothing to worry about; it turns the entire leaf brown, but the problem passes as new leaves form.
