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.
What is the difference between evergreen and deciduous leaves?
Evergreen = an evergreen plant/tree is a one that has leaves throughout the year that are always green and don’t fall out. This is different to deciduous plants, which completely lose their leaves during the winter or dry season.

What do evergreen trees do in winter?
Most trees do ‘slow down’ during winter, and deciduous trees that lose their leaves shut down photosynthesis entirely. Trees with needles (evergreen trees) that are retained over winter can actually photosynthesize during the winter.
Do evergreen trees need water in winter?
Evergreen trees lose water through their needles in the dry winter air, so they need more stored-up water going into the winter season to make up for it. … That’s why it’s especially important to provide a sufficient water supply in the fall, and water during dry spells during the winter.
