Parts of Illinois still recovering from the 2012 drought and trees in those areas likely need water. That’s the message from University of Illinois Extension small farms educator, Doug Gucker, who indicates your tree could be showing signs of stress.
Gucker says it is a good time to try and get your tree some water and there's a few easy, practical methods to do that.
When using a sprinkler to water the trees, Gucker says a good way to measure how much water you've used is to put a soup can down and let it reach two inches.
