Redbud Tree are aboriginal to the United States and can be found from Florida to Pennsylvania and as far west as eastern Texas . The tree is among the first to bloom and is often a bellwether of spring . Redbud trees get their name from the bright red heyday buds that organise along the branches prior to leave of absence appearing , cater a colorful showing . The tree diagram are relatively free of disease , however , the U.S. Forest Service Silvics Manual does manoeuvre to three disease that importantly affect redbud trees .

Botryosphaeria Ribis

Botryosphaeria ribis is a fungus and the case of a canker that is the most serious malady that can affect redbuds tree diagram . The canker spring on the branches of the tree . They are sometimes seeable on the aerofoil of the bark as dark , sunken area with blackened centers . The disease is spread by splashing water or wind that transports spores to tidy constituent of the Sir Herbert Beerbohm Tree . The fungus spreads through the vascular scheme of the tree diagram and slowly block the catamenia of fluid within the plant life . This causes a gradual dying of branches as the stream of water and food is break up .

To deal the disease , prune out all dead branches at least 4 inches below the point of infection and destroy them . Be certain to disinfect pruning tool after each cutting to concentrate the endangerment of spread infection . Fungicides can be used to manipulate the fungus prior to infection , but there is no chemical control for the pestilence once it has become established .

Verticillium Wilt

Verticillium wilt disease is due to the soil - borne fungus Verticillium dahliae and sometimes kills redbud trees , particularly in the Midwestern United States . The disease normally enters the tree through the root system , but can also enter through a lesion . It infects the vascular scheme , preventing water and nutrient from progress to the upper portions of the flora above the contagion . The leaves droop from lack of water and turn scandalmongering , finally dying and light from the tree .

deal verticillium wilting by pruning away and destroying stagnant ramification at least 4 inches below the dead arena . Disinfect pruning tool after each cut to help keep spread the infection . Water redbud trees that are suffering from verticillium wilt disease two to three time per week to a depth of 2 to 3 foot to ensure the flora is receiving enough urine .

Leaf Anthracnose

Leaf anthracnose , also known as leaf situation , occurs primarily in wet weather . It is do by the fungus Mycosphaerella cercidicola . The disease presents as hoary brown or bleak bit with a raised border , later arise a grey appearance on the upper control surface . While this disease can be unsightly , it is generally not serious .

chemic controls are usually not necessary , but limpid copper may be used in serious cases and as a preventative measure . Raking and disposing of fallen leave to reduce the peril of banquet is also helpful .
