Photosynthesis of overwintering evergreen plants | …
Topiary gardens certainly have their place, but transforming the Plant Kingdom into the Animal Kingdom is stressful on a plant’s physiology. (Remember, pruning is a matter of tangible, genetic relationships not magic). Leaves generally cannot grow without a relationship with light. Sunlight, for which they hunger, is all-powerful. Shearing evergreens forces them to grow leaves along their outer parameter only. This inhibits light from reaching the plant’s interior and debilitates the tree’s ability to manufacture or work with chlorophyll. The phenomenon of photosynthesis is the keystone to plant health, and we can make sunlight available to the entire evergreen through a technique called naturalized pruning.
Why Do Deciduous Trees Change Colors And Evergreens …
Flowers may have a full complement of flower parts, or may be missing certain elements. Conifers do not have petals and associated structures.
Origin of plantMiddle English plante from Old EnglishOld French both from Latin planta sprout, seedling ; see plat- in Indo-European roots.
Do evergreen trees photosynthisize in winter
As noted above, deciduous leaves have greater photosynthetic ability than do coniferous ones. That is partly because of their greater surface area, and partly because they invest more nitrogen in leaf building to begin with.

Looking at those Ponderosa Pines outside my window, I can see that almost all the needles are being touched by the sun. In contrast, shade keeps many deciduous leaves from achieving their photosynthetic potential.

Photosynthesis may stop or slow way down as trees close the stomata in their leaves to reduce evapotranspiration—a real hindrance to trees that only bear leaves for a few months a year. In the winter, temperatures are generally mild enough that conifers can keep photosynthesizing, and, of course, there is plenty of rain to fuel growth.
Some trees are evergreens and do not shed their leaves every ..
In the Methow, even deciduous trees tend to be fairly upright in form so that their branches are less likely to catch snow and less likely to break when snow does accumulate. Losing leaves helps protect deciduous trees’ branches, too. Whereas conifers are shaped to shed snow, the upright branches of broadleaved trees would be further compromised if the leaves were present in winter.

I’m writing here about evergreen conifers—those that keep their leaves during the winter—and deciduous broadleaves—those that lose their leaves in the fall. Those qualifications apply to all of the trees that are native to the Methow Watershed, with two exceptions—the Alpine and Western larches ( and )—deciduous conifers that have adapted to extreme environments by adopting characteristics of both types of tree.

At the opposite end of the spectrum are tropical rainforests, which tend to be dominated by broadleaved evergreen trees. When conditions are favorable, broad leaves are more efficient than the needles and scales of conifers.
