A couple of limbs turned brown on the tree that I thought was due to the drought. I watered the tree and removed the dead limbs and noticed that the brown limbs were covered in sap. Now it looks like more limbs are covered and turning brown and the trunk is oozing sap. Can anything be done?
Sounds like your cherry tree has stress cankers or borers. The stress can be caused by drought, other root problems, or disease. The best way to proceed at this point would be for you to water the root zone. Watering should be done during dry periods to make sure the tree does not need to rely on stored energy to survive. This irrigation should be provided within the drip-line of the tree at a rate of one inch per week when the upper 4 to 6 inches of the soil is dry. Use a sprinkler for approximately 2 to 6 hours once or twice a week. You want the soil to be moist to a depth of 6 inches or more. Have a certified arborist examine the tree to determine the cause of stress and appropriate treatments if needed. Please contact us to make an appointment for a consultation at your property.
