On the first day of fall, it’s only appropriate that we write about spectacular autumn foliage. More specifically, we thought it would be good to discuss why leaves change color this time of year. Keep reading to learn more from the experts at Pro Tree Service in Chicago!

Let’s revisit your middle school science class for a moment. According to ScienceDaily, chlorophyll is a green pigment found in plants, algae, and cyanobacteria. You might remember that chlorophyll plays an essential role in the process of photosynthesis, which allows plants to absorb energy from light. 

So how does chlorophyll factor into the changing of leaves? Well, as summer comes to a close and temperatures start to become more fall-like, the chlorophyll in the leaves begins to break down. This is when we see the various color pigments, including red, orange, and yellow. Interestingly, the colors are most vibrant when the end of summer is dry, and the beginning of autumn consists of bright sunny days and cool nights.

Here’s an explanation of the four main leaf colors you’ll see this fall.

Green – Chlorophyll  

As aforementioned, this pigment is responsible for helping trees turn sunlight into food. Outside of the fall months, chlorophyll is the dominant color seen in most leaves until it fades away. We should also mention that trees turn to stored sugars to survive the winter once they stop producing food.

Red – Anthocyanin

Nothing says autumn like the beautiful red leaves found on Red Maples, Red Sumacs, and Scarlet Oaks. While other leaf colors exist in the leaf itself, anthocyanins are produced as the chlorophyll breaks down. The Swamp Chestnut Oak is another common anthocyanin worth checking out this fall.

Orange – Carotene 

You might know carotene as the chemical responsible for giving carrots their orange coloring. Yet many Chicago residents don’t realize that carotene also plays a major role in the changing of leaf color. Those who have a Super Maple in their yard are able to see carotene in action every autumn.

Yellow – Xanthophyll

Fall wouldn’t be the same without bursts of xanthophyll in beeches, ashes, aspens, birches, and oaks. Xanthophyll isn’t just limited to trees, though, as the chemical also contributes its yellow color to autumn corn and squash. 

How Our Tree Service Can Help This Fall

Fall is a time to watch football, consume pumpkin-spiced everything, and, of course, enjoy the colorful foliage. But just because summer is officially over doesn’t mean you can stop paying attention to your trees for the foreseeable future. As we detailed in our fall tree care checklist, autumn provides the perfect opportunity to fertilize, hydrate, and plant.

At Pro Tree Service, we understand that trees require year-round maintenance. Whereas other local tree care companies only operate during the summer, we provide dependable tree care whenever you need it.
