In most cases, growth on trees occurs naturally and causes no harm to the tree. Still, in some cases, it can indicate an underlying issue with tree health. As a result, abnormal tissue development that forms galls or cankers weakens the tree. From pest issues to fungal disease, there are several reasons why your trees might develop lumps and strange growth. Let\u2019s discuss everything you need to know about the problem.<\/p>\n<h2>Lumps and Growths on Trees: What Do They Mean?<\/h2>\n<h3>Is It a Disease? Recognizing Infection<\/h3>\n<p>Bacterial or fungal infections can cause a tree to develop lumps and bumps. These require immediate treatment, or the tree may die and spread to other trees in the yard.<\/p>\n<ul>\n<li>You might notice that the lumps spread rapidly over a small area on the tree trunk or twigs and branches.<\/li>\n<li>Look for sap oozing from the lumps and the presence of a foul smell.<\/li>\n<li>Fungal infections appear as spongy shelf-like masses on the tree, usually on the trunk.<\/li>\n<\/ul>\n<h3>Pest Problems: Insects and Unusual Growth\u00a0on Trees<\/h3>\n<p>Aphids, mites, and gall wasps feed on trees, and these insects&#8217; secretions cause galls and bumps. They use the damaged area of the tree to shelter and spread, giving rise to an insect infestation that threatens the tree\u2019s survival.<\/p>\n<p>Galls can be in a wide variety of colors and shapes and appear on parts of the tree, including:<\/p>\n<ul>\n<li>Leaves<\/li>\n<li>Roots<\/li>\n<li>Flowers<\/li>\n<li>Twigs<\/li>\n<\/ul>\n<p>Take action and spray the problem area with organic pesticides. Don\u2019t use chemical pesticides unless recommended by a professional arborist.<\/p>\n<h3>Identifying Harmful Growths That Damage Trees<\/h3>\n<p>We\u2019ve touched on how cankers, galls, and fruiting fungal infestations threaten tree health, but let\u2019s take a deeper look at what these growths are.<\/p>\n<ul>\n<li><strong><em>Gall<\/em><\/strong> is an abnormal swelling on plants and trees&#8217; stems, leaves, or roots. Common galls are abnormal growths caused by mites, fungi, bacteria, or insects. Crown gall causes rough-woody tumors on the roots, trunk, and branches.<\/li>\n<li><strong><em>Cankers<\/em><\/strong> are sunken areas of dead bark usually caused by bacterial or fungal infections.<\/li>\n<\/ul>\n<p>Prune affected areas where you can. If the tree has signs of decay near the roots that you can\u2019t remove, consult an arborist.<\/p>\n<h3>Is It Natural or Problematic Growth? Decoding Tree Defects<\/h3>\n<p>Growths on trees can be a normal part of the life cycle. They aren\u2019t always a sign that things are going wrong with the tree&#8217;s health.<\/p>\n<p>Don\u2019t worry about a knobby texture on the bark or darkened burrs. That\u2019s just a sign of minor environmental damage and no risk to the tree\u2019s overall health.<\/p>\n<p>Lichen or moss growing on the bark isn\u2019t a problem, and it\u2019s not dangerous to the tree. But if you see sap leaking from the lumps or the bark\u2019s splitting, call an arborist for a professional assessment.<\/p>\n<h3>Treating Lumps and Growths on Trees \u2013 Best Practices for Care and Maintenance<\/h3>\n<p>Prune branches that are affected by galls and other smaller harmless growths. Make sure you\u2019re using sharp, sterile tools so you don\u2019t spread the disease to other trees, and clean the pruning tools after use.<\/p>\n<p>Remove and dispose of cankers and fungal shelves immediately. Please don\u2019t throw the waste in the compost heap or burn it. This will cause the spread of the disease into the yard.<\/p>\n<p>Spray the affected area with fungicide and monitor it for spread. If it doesn\u2019t recover, call a professional arborist for an evaluation.<\/p>\n<h2>Arbor Hills Tree Farm &amp; Nursery Omaha<\/h2>\n<p>We provide the Highest Quality Field Grown\u00a0Nebraska Trees\u00a0and Shrubs &#8211; directly to our customers, at the lowest possible price.<\/p>\n<p><em><strong>Whether you are looking for trees for: <\/strong><\/em><\/p>\n<ul>\n<li>new home landscaping<\/li>\n<li>wind blockage<\/li>\n<li>commercial or residential<\/li>\n<\/ul>\n<p>Simply select the tree(s) you want, and they will be ready for pickup or delivery the following Saturday Morning.
