Sap is a viscous liquid that carries nutrients throughout the tree to the areas where they are most needed. As to the sap in pines, there really is no pine tree sap season. Pine trees produce sap all year long but, during the winter, some of the sap leaves the branches and trunk.

How to Stop a Tree From Dripping Sap

1. Prune the Tree. In some cases, you can stop a tree from dripping sap by pruning it.
2. Apply a Pruning Sealant. Pruning alone won’t necessarily stop a tree from dripping sap.
3. Apply an Insecticide. It’s also a good idea to use an insecticide on any tree that’s dripping sap.
4. Be Patient.

Oozing of sap from the trunk of a pine tree can be an early sign of bark beetle damage. The sap accumulates near the bore hole in the bark and the sticky mess is called a “pitch tube.” The pine produces excessive amounts of sap to protect itself against the bark beetle. Several types of beetles can attack pines.

Pruning, damage, pests and disease are common reasons why trees ooze and drip sap. However, certain species of trees naturally produce more sap then others, and are more susceptible to problems that lead to an excessive amount of sap dripping.

For example, turkeys and quail readily seek and eat pine seeds. During certain periods of the year, squirrels also feed on pine seeds. Squirrel cuttings can often be observed under pine trees, especially during September. In addition to food, pines provide nesting habitat for birds and squirrels.

These plants love the acid soil and the shade and filtered sunlight the trees provide.
