Why evergreen trees do not lose leaves?
This special needle shape, along with a waxy coating, allows the evergreens to conserve water during summer and winter, which is needed for that continued photosynthesis process. So because they can conserve more water than their deciduous counterparts, their leaves stay green and remain attached longer.Jan 7, 2021

Why do evergreen trees not lose their leaves?
Evergreens have strong leaves that are rolled up as long, thin needles with a waxy coating. The needle shape enables the evergreens to conserve water during the summer and winter to allow the photosynthesis process to continue. This is why the needle leaves can remain attached longer and stay green all year.Feb 21, 2022
How do evergreen trees survive winter?
Evergreens have thin needles with a waxy coating: adaptations that also reduce water loss! The outer bark of trees contains many air pockets, rather than living cells filled with liquid that can freeze. The air pockets in bark help provide insulation and protection against freezing and cracking during the winter.
Do evergreen trees lose leaves?

What happens to evergreen trees in autumn?
Though it largely goes unnoticed, evergreens also lose a portion of their foliage (needles) on a yearly basis. Seasonal needle drop on most evergreens occurs in fall. Needle loss is most noticeable on white pines. As much as one-half of the needles on white pines may drop in early fall.Oct 4, 2018
Why do trees not lose their leaves?
There is no real consensus in the tree research community as to why some tree species keep their leaves, but there are a number of theories. The main one is that keeping leaves protects next year's buds from browsing deer or the drying winds of winter.Dec 24, 2018
Why are leaves staying on trees?
If the tree receives excess nitrogen too late in the growing season, it tends to focus its energy on tender new growth. In the fall, it won't be able to harden up as quickly as it normally would, so it remains green and tender, holding onto its leaves late in the fall.
