How to identify water stress??
I've never had to give too much thought to lack of water. I have always had the crutch of a water hose and spigot coming out of my home. That combined with a small garden made it a non-issue.
With the drought in chicago, however, I have begun to wonder about identifying water stress. What should I look for in plants that are stressed for water? How do I know when the plant has enough water and to stop? I'm sure that there is a aite with a discussion of this, I just have never seen it. Any help in how to tell is a plant is getting enough water would be appreciated.
