Sap Dripping From Trunk Of Tree
We have a weeping cherry tree that is 'bleeding sap'. There are several long runs of sap running down the trunk. What is cause and cure?

Fruit trees are very susceptible to frost cracks or bark splitting due to the fact that they have thin bark. These are caused by drastic temperature fluctuations, especially in the winter or by warm sun on the tree in the winter time. This then causes sap oozing. It can be reduced by providing some extra protection to the tree, especially the lower part of the tree. Normally, a paper wrap is used to give the trunk some extra winter protection.
