September:

• Continue regular watering of newly planted trees.

• Water established trees during periods of drought.

• Prune branches that are clearly dead or damaged. If a tree is showing signs of disease (e.g. galls), contact a professional regarding best time of year to remove. Sometimes pruning a diseased branch or limb will release vectors (e.g. fungus spores) and cause the disease to spread.

• Protect trees from deer/elk rub and from rodents eating the bark.
