Deicing salt injury
- Soil salt damage causes leaf edges or margins to appear burnt or scorched progressing toward the mid-vein
- Run-off salt kills roots which results in die-back of branches
- Affected trees leaf out later than other non-infected trees
- Damage most noticeable in spring and the summer growing season

Drought
- Foliage sometimes turn brown around the edges but more commonly turns a dull, gray-green color
- Dried brown to gray-green leaves hang on the tree or foliage drops unseasonably and litters the ground under the tree
- Severe drought stress may cause dieback of individual branches starting at branch tips
- More information on watering trees and shrubs
