Signs of stress - Knowledgebase Question

After a very hot summer, some of our trees (and one shrub) are showing signs of stress. We see this in our neighbour's yards as well. Although we didn't adequately water in July, we have been faithfully watering/soaking for the last 4 weeks, but don't see any improvement, and some look worse. The trees are junipers, cedars and pine trees. Of particular concern is a 30 ft. birch and a 6 ft. Northern Lights Azalea that appear to be dying. Can we save them?

Established trees and shrubs are remarkably adaptable and will generally recover from a droughty summer. For evidence, just look at of all the trees in the forested areas near your home. They may look puny now, but as soon as cooler temperatures and natural rainfall saturate the soil, they perk right up. I suspect your trees and shrubs will react in this same way. Most trees and shrubs can get along nicely with about one-inch of water per week during the growing season. Continue to deeply soak your trees and azalea once each week until natural rainfall takes over. I suspect that by next spring they will have recovered and will look fine.

Best wishes with your landscape!
