![]() ![]() Some other ways to help prevent this and other fungal diseases are to clean up dead leaves in the fall. Stewart’s leaf spray treatment can help combat this fungus and prevent it from spreading. While it’s unsightly, it doesn’t usually cause serious, lasting issues. The leaf spot fungus spreads in the spring and damages trees throughout the summer months. Foliage damage will become progressively worse, and often the leaves will fall off of the tree prematurely. It starts with small dots of discoloration and gradually spreads until the foliage is covered in black/brown spots (and lesions in some cases). Leaf spot is a fungal disease that causes brown and black spots to develop on tree leaves. Stewart’s has an iron chlorosis treatment program for trees struggling with iron deficiencies. To survive, these trees need chelated iron injections either into the soil or directly into the trunk (depending on the size of the tree). Iron chlorosis is a common problem in Utah because the alkaline soil makes it too difficult for maples, oaks, and other tree varieties to intake the iron in the soil. Eventually, the leaves start to turn yellow around the edges they then turn completely yellow and fall off of the tree prematurely. This usually begins in the spring and summer. The deficiency first turns the leaves light green, causing leaf veins to appear dark green. Iron chlorosis occurs in maple trees when their roots struggle to absorb iron in the soil. Some varieties of aphids also create a white, fluffy substance that sticks to the branches. You may also see the aphids themselves-tiny black or gray specks-on the leaves and branches. If aphids are attacking your tree, you’ll see shriveled, sticky-looking leaves clumped together. However, some varieties prefer to feed on branches, roots, and twigs instead of new leaves. Aphids prefer to feed on new growth, so they are most common in spring and early summer. They feast on a variety of tree foliage, including maple, apple, ash, aspen, beech, birch, cottonwood, stone fruit, willow tree varieties, and more. Many varieties of aphids exist, and they can cause a lot of damage to a tree’s foliage that may eventually prevent the tree from receiving all the nutrients it needs. ![]() In addition to maple trees, anthracnose affects ash, boxelder, oak, and sycamore trees in Utah but it can be treated with leaf disease control sprays. When this happens, the disease becomes much more difficult and expensive to treat because it requires injections into the trunk. Multiplying on leaves during cool, wet spring weather, anthracnose causes the leaves to turn brown and dry out near the veins at first, then it spreads over the whole leaf.Īnthracnose can also spread to twigs and branches on the tree. Anthracnose AnthracnoseĪnthracnose is a leaf disease caused by various types of fungi that survive the winter months in dead leaves and twigs. Learn how to prevent these diseases and how to treat them if your tree is already struggling. They most commonly suffer from the following: They mainly live in bottomland forests.Maple trees suffer from a variety of problems. It flowers between March and April and flowers May through June in winged pairs, what so many lovingly call helicopters. As the tree ages, that silver-grey trunk begins to get darker and flaky. The middle lobe is the longest and the base of the lobe is V-shaped. The leaves are very unique and can range between 2-5 inches long with 3-5 lobes. It has a long trunk with an irregular crown. However, it prefers to grow in moist conditions that are slightly acidic. It is not usually found in the forest and is tolerant of most soils to grow in. They can be found growing between Eastern Canada down to South Florida and all the way east as far as Texas. It is a stunning tree that provides a ton of shade and it has the greatest north-south distribution of all tree species along the east coast, according to. ![]() Its fall foliage can range from its namesake to yellow or greenish color. They first begin with stunning smooth or silver-grey bark and have very dense roots. They are very popular ornamental trees that can grow between 40 and 60 feet in the wild! The leaves can vary between 3 and 5 lobed leaves, with lobes that are separated by angles very similar to the letter V. They can also be called Scarlet Maples or Soft Maples. Red maples come from the Aceraceae or Maple family. ![]()
