We have the benefit of getting out of this heat but our poor plants get no relief.
We have received several calls in recent days regarding suffering trees and shrubs. We all know how to keep our flower gardens well watered but the trees and shrubs need a little more attention then the sprinkles can provide.
During these “dog days,” its a good idea to thoroughly water your trees and shrubs to be certain the root ball is getting water. Typically, a sprinkler system will water only 1 ” 1/2 “- 2 ” below the surface, where shrubs need water much deeper – 9 ” to 12 ” deep.
The best time of the day to water is early morning, but the evening will be fine. Avoid watering during the mid-day heat. We like using the hose directly on the base of the plant. If your ‘young’ trees are showing stress, a slow trickle of water at the base of the tree for 15-20 minutes will help tremendously.
I hope this helps and I’m certain your plants will appreciate your efforts!
