Foliar diseases caused by fungi are common this time of year. With this in mind, as leaves appear, it is important to notice anything unusual in the foliage of your trees.
Some signs of an issue include:
- Discolored or dead “spots” on leaves
- Unusual coating on the leaf surface
- Browning or yellowing on the outer margins of leaves or along leaf veins
- Bumps or pustules on leaves
- Loss of needles on conifers
Virtually any tree species can be impacted by foliar diseases. Infected trees can be unsightly and tree health issues may arise when defoliation, or loss of leaves, occurs. Effective management varies according to the underlying problem so trees with symptoms should be inspected by a certified arborist.
