Trees are big, beautiful creations in nature. They benefit their environment greatly by improving air quality, providing oxygen, conserving water, preserving soil, and supporting wildlife.
If you’ve ever been outside amongst the pine trees and touched the trunk or sat against it, you’ve probably found yourself covered in a sticky substance with a pungent smell: sap.
What Is Sap?
Tree sap is a golden, sticky substance that moves through trees to help circulate water and nutrients; think of blood in your veins. While sap flows in trees all year long, it’s most prominent in the spring and early summer.
Typically, sap will be golden in color and indicate a healthy tree when it’s oozing from the trunk. But, if you see white or puddling sap, the tree may be infected by a pest or a disease.
When Does Sap Stop Falling From Trees?
This is a trick question; sap technically never stops falling from trees. Because sap is what circulates water and nutrients throughout the tree, the sap must continually flow.
However, the quantity of sap oozing from the tree decreases in the winter (and colder temperatures) and then picks back up in the spring as temperatures change back to warm and pressure increases.
What Is Sap Used For?
The primary purpose of sap is to transport nutrients throughout the tree. But pine tree sap can also be used in glue, candles, and for starting fires.
Another use for pine tree sap is as a salve for wounds due to its antibacterial properties. Herbal supplement manufacturers use pine sap for anti-inflammatory teas and broths to treat sore throats or other ailments.
You can also use pine tree sap as pitch glue to repair holes in your tent. Or to improve the water resistance of a tarp.
Some more natural ways to use sap include burning (as a lamp) and pine tar soap.

Still got questions? Here are some of the most commonly asked about pine tree sap.
What is sap?
Tree sap is a golden, sticky substance that circulates water and nutrients throughout the tree.
When does sap stop falling from trees?
You will find sap oozing from pine trees all year long. However, the winter is when the sap is the most scarce.
Why do pine trees give off sap?
All trees give off sap. That is what transfers the water and nutrients throughout the tree.

What’s the difference between tree sap and tree resin?
All trees produce sap to transport water and nutrients throughout the tree. Tree resin is unique to trees in the Pinaceae family. Like pine, fir, and cedar trees.
Final Notes
The sap is an integral part of tree health, and it’s a good thing when you see it oozing in that beautiful, golden color. If the sap is discolored or oozing excessively, however, it could be an indicator that the tree is diseased or affected by insects.
So, when does sap stop falling from trees? Because sap transports water and nutrients throughout the tree, it never truly stops flowing. In the colder months and winter, you’ll see less sap coating the tree and around the base of the trunk.
