On the white paper the spider mites can be easily seen. Another way to examine for spider mites is to take a sheet of white paper, hold it under a group of leaves and give the leaves a few sharp taps to shake some of the spider mites loose. You may need to use a small magnifying glass to adequately see the spider mites. To confirm if the tree has a spider mite infestation take a close look at the undersides of the leaves for small insects, the size of ground pepper. Intense infestations during hot, dry weather can cause the leaves to curl and drop. A fine silken webbing can sometimes be seen on the underside of the leaves. Mites infest leaves and cause the leaves to appear speckled with yellow spots or wilted and curled. Spider mites are an extremely tiny pest, and generally appear as a brown, red or purple specks on the underside of leaves. In the spring or early summer if the crawling nymphs are present, spray the trees with to prevent the new nymphs from further infecting the tree. The Horticultural oil serves to suffocate the scale and eggs. ![]() To effectively control scale insects and limit damage, Horticultural Oil should be sprayed on the tree. This is the only time in the life cycle of scale that the insect moves. In the spring or mid-summer, small, almost invisible nymphs emerge from under the female shells and move to infect new areas of the tree. This is a secretion from the scale called honeydew and often acts as an attractant for ants or as a growing source for sooty mold. Often a sticky substance can be found near the scale or on the leaves. The scale sucks sap from the tree and causes the leaves to turn yellow and drop. ![]() When adult scale is attached to the tree, it often appears as crusty or waxy bumps on the tree and is often mistaken for part of the tree’s own growth, but it is actually an insect. Scale is most common on the new tender woody growth. Scale insects are small, non-mobile insects that attach themselves to the wood and sometimes the foliage. The Horticultural Oil should be applied when the temperatures are between 35 and 85 degrees Fahrenheit. Use Horticultural Oil in a dormant spray dosage to control treehoppers. The insect itself is not seen but the white, sticky froth covering the eggs is quite noticeable (see image). Treehoppers lay eggs under the bark of twigs. 'Silver Cloud' - The leaves are variegated with pink and white. ![]() 'Flame' ('Plena') - Double pink flowers appear at the same time as the leaves. This cultivar may not be as hardy as the species. 'Forest Pansy' - The new leaves are scarlet becoming maroon as they mature. The Redbud grows throughout much of the eastern United States and extends as far west as Texas, Oklahoma and Kansas. Redbud has a yellow fall color and is shade tolerant. The flowers are even produced on large trunks. The purple pink flowers of the eastern redbud appear all over the tree in early spring. The tree is one of the earliest flowering trees and is often used to add color to gardens. The Redbud is a poplar ornamental tree, which can be found in many gardens and streetscapes. The Redbud tree is a relatively small tree with spreading branches and a small short trunk. ![]() Use an Annual Care Kit to treat your redbud tree, an excellent annual maintenance practice.įertilizer: TreeHelp Premium Fertilizer for Redbud
