|What can I do to keep the bark from splitting on peach trees and how do I get rid of the wax that seeps from the splits in the bark?|
|Peach trees are in the same category as cherries, plums and apricots - members of the Prunus family - and they all ooze sap. That's just their nature. Sometimes a disease called gummosis will attack the trees and cause excessive flows of sap. Controlling the disease is difficult, but not impossible.
Try to prevent trunk injuries; protect the trunk by whitewashing with dilute latex-based white paint, control fungal diseases and insects, and don't overfertilize (especially with nitrogen).
