Experiencing Change of Season

In a very short period of time we are experiencing the end of summer, the beginning of autumn and since we also experienced snow already, it does feel we are experiencing winter too.

Earlier the question arose in our household how the trees know when it is time to substract its life juices from its leafs. Especially when it is still warm outside. How does nature know when to prepare for winter?

We came to the conclusion that nature is preparing herself everywhere in the same way. When the longest day of the year has past, the Summer Solstice or Litha, nature starts preparing for winter. Days are becoming shorter and that is how she knows winter is coming.

More on the seasons explained in a Pagan way.

Change of leaf color explained

20131004-224521.jpgLeaves are nature’s food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into oxygen and glucose. Oxygen is a gas in the air that we need to breathe. Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into oxygen and sugar is called photosynthesis. That means “putting together with light.” A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is what gives plants their green color.

As summer ends and autumn comes, the days get shorter and shorter. This is how the trees “know” to begin getting ready for winter.

During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange colors. Small amounts of these colors have been in the leaves all along. We just can’t see them in the summer, because they are covered up by the green chlorophyll.

The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves.

It is the combination of all these things that make the beautiful fall foliage colors we enjoy each year.

    Nice post! We’re a bit north of you but not quite as close to the mountains, so we didn’t get any snow. One thing I’ve noticed after moving to Colorado from New England is that fall is primarily yellow here, rather than the variety of shades we had in Maine. But it’s still pretty 🙂

      Hi Miriam, we went for a drive up through the mountains. On Friday we went to Frisco and saw those beautiful autumn colors. Mostly yellow though. But beautiful nevertheless with the sun shining on the leaves, those mountains and in the back you could already see snowy mountain tops. Yesterday we were trying to get to Nederland, which we didn’t get to. But we did see these snowy sceneries. We were told that after that first snowfall, all the signs of fall would be gone. What is your experience?
