Common tree problems that occur in the fall

Trees play an important role in our environment. They help purify the air we breathe and provide  a home for wildlife. Trees also add beauty to our landscape. But like all living things, trees need  care to keep them healthy. Unfortunately, as the seasons progress, your trees are at risk for  developing certain problems, from disease and pest outbreaks to nutritional deficiencies, animal  damage, environmental issues, and more. 

Take a closer look at your landscape trees this season. Don’t fall victim to the most common tree  problems that occur in the fall. Learn about the issues to watch out for below. 

Common threats to landscape trees this year

Most trees experience the most problems during the fall season. Many of these problems are caused  by changes in weather and environmental conditions. The most common tree problems that occur  in the fall include: 

• Leaf drops 
  • This is one of the most common problems trees experiences in the fall. As temperatures drop and  days get shorter, trees begin to lose their leaves. This is a natural process, but it can be problematic  for trees that are already struggling. Falling leaves can cause additional stress and damage to trees,  and in some cases, can even lead to death. 
• Disease 
  • Fall is also a time when diseases can easily spread to trees. Many diseases thrive in the cooler,  wetter fall weather. Disease is more likely to occur if the tree is already weak or stressed. Common  diseases that affect trees in the fall include leaf spot, powdery mildew, and root rot. 
• Pest 
  • Pests are also a major problem for trees during the fall. Many pests, including aphids, mites and  scale insects, are attracted to the sweet nectar the trees produce during this time of the year. These  pests can cause serious damage to trees and, in some cases, kill them. 
• Damage from wind and cold 
  • Strong winds are common in the fall and can cause significant damage to trees. High winds can  break branches, uproot trees, and topple weak or dead trees. Frost can also cause significant  damage to trees during the fall. Frost can kill leaves, branches, and even entire trees. It is important  to protect your trees from frost damage by providing adequate water and cover. 

Tree care tips

Here are some tips on how to keep your trees healthy:

• Water your tree regularly – Trees need at least 1 to 2 inches of water per week, depending  on the weather. The best time to water your tree is early in the morning before the sun gets  too hot. 
• Mulch your trees – Mulch helps retain moisture in the soil and keeps roots cool in the  summer. Apply mulch around the base of the tree, being careful not to pile the mulch too  high on the tree trunk. 
• Prune your trees regularly – Pruning helps remove dead or diseased branches and  promotes new growth. Prune when the tree is dormant winter for most trees. 
• Beware of pests and diseases –  Look carefully for signs of pests or disease, such as  discolored leaves or branches. If you notice anything suspicious, contact a certified arborist  for help.
