Seeing Red

One of the earliest fall colors to enjoy in California’s mountains is red. Though if you seek it, look downward. As, the red of which I write is crawling along the ground.

Why Don’t Evergreens Lose Their Leaves?

Actually, they do.  It just doesn’t happen all at once. Evergreen trees have both broad leafs and needles. Madrone, magnolia and photinia are examples of broadleaved evergreens, while pine, fir, cedar, spruce, and redwood have needled leaves. Evergreen needles can last anywhere from a year to 20 years, but eventually they are replaced by new […]

Why Do Leaves Change Color?

Leaves on deciduous trees change color in autumn from green to various hues of lime, yellow, gold, orange, red and brown because of a combination of shorter days and colder temperatures. Throughout spring and summer, green chlorophyll (which allows trees to absorb sunlight and produce nutrients) is made and replaced constantly. However, as days grow […]

Why Do Trees Lose Their Leaves?

It’s survival not just of the fittest, but of the wisest. Deciduous trees drop their leaves in order to survive.  As days grow shorter and colder, deciduous trees shut down veins and capillaries (that carry water and nutrients) with a barrier of cells that form at the leaf’s stem. Called “abscission” cells, the barrier prevents […]
