Spruce Blues and Wet-Weather Woes

blue spruceWhen I’m asked to diagnose tree problems, folks naturally want the remedy. Sometimes the only solution is tree removal; other times it’s a cable brace, pest management, corrective pruning or fertilizing. But increasingly, the diagnosis is climate change. If anyone knows how to solve that through an arboricultural practice, please let me know. 

With rising temperatures, a novel weather pattern has taken hold with longer and more intense dry and wet periods. In 2012 many areas had the lowest soil moisture ever recorded. Nonstop rain in 2013 led to flooding and farm disaster relief. A drought in 2016 set more records in some places, and catastrophic flooding hit in 2017. Drought followed in 2018, and 2019 was another massive flood year. Prolonged dry spells cause root dieback, weakening trees for several years afterward. But unusually wet seasons are just as bad for trees.
