Successful tree care in Virginia Beach involves regular tree trimming and tree pruning. Additionally, you should be able to recognize signs of disease on your trees to keep them healthy and attractive. Some tree conditions can result in mild disfiguration while others can lead to tree death. Our team has become familiar with a few common diseases that can affect your trees, even with proper tree trimming and pruning.
First is powdery mildew. The result of a number of fungal pathogens, powdery mildew grows on the surface of affected plants, and can be found on a broad range of trees in North America. Powdery mildew can cause leaves, flowers, and shoots to grow abnormally, and can stunt the growth of young trees. To prevent this disease, select fungus-resistant tree varieties and avoid planting in shady or crowded areas.
Next, we have apple scab. An early season leaf disease that affects crabapple trees, apple scab shows up in the form of scab-like lesions on leaves. This condition is mostly an aesthetic problem, but can also lead to premature defoliation in affected trees. Tree care for plants infected with apple scab should begin with fungicidal treatments.
Now let’s take a look at oak wilt. One of the more severe diseases that affects trees, oak wilt is a systemic fungal condition that can kill infected plants. Oak wilt can affect many tree species and is spread by beetles and infected grafts. Early symptoms include premature defoliation, rapid leaf discoloration, and yellowed leaf veins. Some tree species respond to treatments, but those in the red oak family do not. As a preventative measure, inject susceptible trees with a systemic fungicide during the growing season.
Finally, lethal yellow of palm, which mainly affects Florida and Texas, is caused by phytoplasma transmitted by planthopper insects. Symptoms include premature fruit dropping, yellowing foliage, and flower death. Left untreated, an infected palm will usually die within five months. Using insecticides to prevent transmission of lethal yellow of palm is an effective prevention method, and infected trees sometimes respond to antibiotic injections.
Even if you practice good tree care in Hampton Roads, it’s possible for one of your trees to be unwell. To help keep your trees healthy, look for signs of dead limbs, mushroom growth, insect damage, and new growth.
