Since dogwood trees are an essential part of many ecosystems, providing food & shelter for various birds, insects, & other wildlife, you should do your best to help them thrive for longevity.

Unfortunately, dogwood trees are susceptible to a variety of pests, including spider mites which are tiny arachnids that can cause significant damage to your trees if left unchecked.

Therefore, without wasting time, let’s explore the signs of spider mites on dogwood trees, the damage they can cause, and how to identify & deal with early infestations.

3 Signs of Spider Mites on Dogwood Trees

Many types of research have shown that spider mites can reduce the growth & vigor of dogwood trees. Spider mites can even kill the tree in case of severe infestation.

Therefore, knowing the signs of spider mite infestation on dogwood trees will keep you ahead of identifying and treating them at an early stage before it gets severe.

Fine Webbing: Spider mites are known to spin fine webbing on trees’ undersides of leaves & between branches. If you notice fine mist or a thick mat-like structure, spider mites are likely webbing. Depending on the infestation’s severity, you should notice a lot of them.

Yellow or Bronzed Leaves: Like many insects, spider mites also feed on the sap of dogwood leaves. You’ll likely notice noticeable discoloration on the leaves closest to the ground. You may also notice yellowing or bronzing of the foliage.
Stunted Growth & Premature Leaf Drop: If your tree is suffering from severe spider mite infestations, it can cause stunted growth or even death of the dogwood tree. Your tree leaves can easily become damaged by spider mite feeding, causing them to drop from the tree prematurely.,

Note: A study by the University of Kentucky found that pests like spider mites can cause significant defoliation & stunting of dogwood trees. It will also lead to reduced flower and seed production.

Causes of Spider Mite Infestation

There can be many causes of Spider-Mites infestation on a dogwood tree, including environmental factors like hot & dry weather, lack of Water, and poor air circulation.

In addition, excessive use of fertilization or over-fertilization of the tree can also lead to an increased number of spider mites population because over-fertilization usually disrupts the ecosystem’s natural balance.

In particular, You should never overuse nitrogen fertilizers as these can lead to a higher susceptibility to spider mite infestations. Apart from all these, it would help if you never kept your plants and tree in low light or high humidity conditions as this also contributes to Spider-Mites infestations.

Also, avoid overcrowding, which may reduce air circulation, leading to increased humidity levels and contributing to spider mite population growth. You should note that low light conditions weaken trees, making them more susceptible to infestations.
