How does an evergreen's leaf keep from freezing in the winter?

Question

Always wondered precisely how evergreens keep green and can survive the cold, and how much they can withstand.

Answer 1

Evergreen trees keep their leaves and keep
making food even in the winter. Evergreens
work in winter because their leaves, or
“needles,” are thick and often waxy, which
seals in moisture. In summer, tiny openings
on the bottoms of the needles let water out.
In winter, those openings close to prevent
water loss when the ground is frozen and they can't get water from the roots.
Pines, spruces, and cedars don't lose their leaves, or needles, in winter. The needles are covered with a heavy wax coating and the fluids inside the cells contain substances that resist freezing. Evergreen leaves can live for several years before they fall and are replaced by new growth.

Answer 2

They have cell membranes resistant to stiffening caused by cold, and produce proteins that serve as an antifreeze, often through sugars distributed through the leaves.

Being resistant to cold is not why Evergreens are ever green. They're actually more common in warmer climates. The reason they are ever green is that losing leaves and regrowing leaves takes energy. In nutrient poor soil, evergreens have an advantage because they don't shed and regrow leaves.

Answer 3

Mulch roots and stems with mushroom manure or leaves approximately 10inches severe. whilst using leaves conceal with compost or soil to maintain them from being blown away with the aid of the wind. interior the spring unfold this compost mulch around the basis section. it truly is ideal to take the leaves used for mulching to the composter.
