Spring
Do not prune Yellowwood in the winter or spring because the wounds will bleed sap profusely
Summer
Water the tree during dry weather for the first couple of years or until you are sure it is established.
Summer is the time to prune Yellowwood to avoid the bleeding of sap. It should be pruned when it is young to develop branches having a wide angle with the trunk and a “U” shaped crotch. These should be pruned back so that they are not allowed to grow larger than half the diameter of the trunk. Develop 7 to 10 major lateral limbs spaced along the trunk, not clustered together. This will help them develop strong attachments to the trunk and provide for a long-lived tree. You might also remove the lower branches when the tree is young to prevent formation of a short trunk.
