Though we call them needles, the green of pines and other evergreens are actually leaves. They serve the same purpose as the leaves of deciduous trees, but their characteristics allow them to remain on evergreen trees, only dropping off after several years.

Why do leaves stay on trees in winter?

Because some marcescent species' leaves do not decompose well, the increased photodegradation may allow them to decompose better once they finally fall off the tree. Others theorize that leaves which remain on a tree due to marcescence allow the tree to trap snow during the winter months.

Why are pine trees green?

Evergreens and Pine Trees Evergreens store units of essential water in their leaves in preparation for winter, and foods necessary for the trees' growth are manufactured in the leaves in cells containing chlorophyll, which gives the leaves their green color.

Do evergreen trees produce oxygen in the winter?

Respiration, the process that trees use to absorb carbon dioxide and produce oxygen, comes to a standstill when photosynthesis is not happening. Evergreen trees will continue to produce oxygen throughout the winter. Deciduous trees do not produce oxygen while they are dormant, except in some green twigs or bark.

How long will pine needles stay green?

Evergreens usually keep their needles for two to three years. If you see red needles that are closer to the stem, those are the ones that are getting ready to drop.

Why evergreen forests are always green?

They look green because the trees don't synchronously drop all their leaves at one time so they are always green (evergreen). Some trees are deciduous, they extract nutrients from the leaves in anticipation of severe conditions such as freezing temperatures which would injure the leaves.

How do trees not die in the winter?

Trees go through a process similar to hibernation called dormancy, and that's what keeps them alive during the winter. Dormancy is like hibernation in that everything within the plant slows down — metabolism, energy consumption, growth and more. The first part of dormancy is when trees lose their leaves.

Do trees still grow in the winter?

Yes and no! As long as the ground temperature is above freezing, tree roots can and do continue to grow. As soil temperature moves closer to 36°, roots grow less. Overall, it's safe to say your tree roots do grow a bit during winter.
