Q.how long will sap rise for in a oak tree

jackall added on May 25, 2012 | Answered

We have a large woodland oak next to our garden and the sap is covering everything. How long will this sticky mess go on for?

If you are still seeing "sap", then it is not sap. It is honeydew and the tree has a pest infestation (likely aphids). It needs to be treated with a pesticide, preferably a systemic one like neem oil. That should clear up the situation.
