How to Tell if Dogwood Trees Need Water?
When dogwood trees are dehydrated, you will notice that the leaves become dry and start to turn brown around the edges. The leaves may also start to fall and the color of the tree overall will be less vivid. This can happen during consecutive hot days without rain. If you start to notice this, deeply water the soil and the base of the tree to revive it.
How Do You Know When Your Dogwood Tree is Sufficiently Watered?
