We have some of the most beautiful trees in Georgia; New England can eat its heart out. Still, Georgia trees fall prey to pests and diseases easily, especially in our humid weather. We here at Gordon Pro Tree Service warn of the following five things that can spell trouble and even death for your trees. Here’s what to look for and how to avoid damage.
Plum or Cherry Tree Black Knot
If your plum or cherry tree looks as if it has black bumps or knots on it, it might be suffering from black knot. This fungal infection forms what looks like normal tree knots on the bark but they are dark. As the fungus spreads, the knot increases in size and weakens the tree. It can also misshape the tree. Now is the time to inspect for black knot. You can see the black knots easier on a winter-bare tree.
You can get powdery mildew on your trees, shrubs and even rose bushes. Crepe Myrtles and Dogwoods are most susceptible to this fungus. The mildew creates white, dusty-looking spots on the leaves – hence its name – and it’s best to cut away the infected leaves. The rest of the tree should be treated with fungicide and you can avoid powdery mildew by pruning your trees regularly to increase airflow.
Oak Leaf Blister
As its name suggests, oak leaf blister affects oak tree leaves. It doesn’t matter the species of oak trees you have planted in your yard; it can attack them all. To detect oak leaf blister, look for yellowish-brown or yellowish-white lesions on your tree leaves. The lesions can grow as big as 2 inches in diameter and you can avoid oak leaf blister by keeping your trees healthy with ample drainage and plenty of water.
Pine trees are incredibly resilient but they are also incredibly tasty to pine beetles. These pests are damaging and can even kill your pine trees. Female beetles bore into your pine tree to create nests where they lay their eggs. These nests alone can kill the tree. Signs you have pine beetles include pine resin on the branches and trunk. The resin forms white bumps, so look for those on your pine trees.
Aphids love foliage no matter what it is. They feed off leaves, so yellow, spotty leaves are a sign you have aphids making a meal out of your trees. Aphids come in numerous species but the good thing about them (if there is anything good about an aphid infestation) is they can be controlled naturally. Head to the garden store and buy ladybugs. They love aphids and will eat them all up.
