Signs of a Diseased Tree – Dieback, Tree Suckers & Water Sprouts
Many diverse diseases affect your landscape, shrubs and trees. Identifying these diseases is critical because, not all tree diseases can be controlled. We love to watch things grow when we garden but we must note that not all growth is positive or advantageous to the trees. Some of these growths take energy away from the tree; common examples include water sprouts and suckers. At 72tree.com we often see the damaging effects of tree disease, and in this article, dieback, tree suckers and water sprouts are the disorders we’ll be discussing.
Dieback of a Tree or Its Limbs
In spring as the weather gets warmer, and buds start noticeably leafing out, you might notice that a section or even an entire limb is not leafing out consistent with the rest of the tree. Dieback is a condition in which the ends of the tree branches die. These sections are generally located at the limb tips, but can also be entire limbs or sections of the tree where there will be no leaves. Most times, this is a sign that all is not right with the tree.
Water Sprouts Due to Branch Removal
Water sprouts are dynamic shoots that develop from dormant buds either on large branches or trunks of a tree. They are usually upright and in many cases occur as a result of the removal or trimming of large branches. Heavy pruning may also lead to the production of more sprouts. Tree stress may also result in water sprout growth, but it’s not usually as vibrant as those that occur due to pruning.
Trees should be checked regularly. If you notice new shoots, eliminate them by rubbing them off as they emerge. Large water sprouts can be pruned off close to the trees trunk. Water sprouts can ruin a tree’s shape and they also divert the tree’s energy by blocking air circulation and light. Though not advised, some allow sprouts to grow in the place of missing branches, but it may lead to a reduction in quality of the tree’s ability to bear more fruits. Also, water sprouts are more inclined to promote tears, disease and breaks, as they are generally weaker than other branches.
Suckers are un-planned, vegetative growths that stem from a tree’s root system. Suckers grow from rootstock and divert nutrients away from the trees top growth. There isn’t any actual benefit from letting suckers grow because, rootstocks are usually different from the type of tree that you planted (example – a Gala apple tree will not have a Gala apple rootstock).
To find and cut from the base of a sucker, you may have to pull back any ground cover and dig up some soil to fully expose the sucker. Ensure that as much growth as possible is removed to reduce the potential of them popping up again. If they do re-emerge, this simple process will have to be repeated. Although suckers and water sprouts are similar, remember suckers originate from the root or base of the tree.
Tree Disease Prevention and Care
You might be able to deal with a disease that occurs on your trees and shrubs but you ought to consider consulting a local arborist or tree service professional if you are uncertain. The arborist will identify any disease and offer you the best treatment options and the ideal time to care for the tree.
Early spring (during most maintenance pruning) is the best time to remove both water sprouts and tree suckers. However, these unwanted growths sometimes sprout and occur during the growing season, they should be removed as soon as you notice their existence. Your trees will thank you and be fruitful!
