What makes autumn leaves change color?

Fall is officially here, which means the leaves will change from green to shades of red, yellow, and orange. But why exactly does this annual event take place?

It all boils down to photosynthesis.

Leaves change color as chlorophyll, the pigment that makes plants green, begins to break down in colder weather, according to the National Park Service.

“When the temperature drops and there is less daylight, the tree begins to conserve the energy it generated in the spring and summer months,” the NPS explains. “As autumn progresses, a tree will send a substance to each leaf called an enzyme that is directed to take apart chlorophyll pigments.”

Once the chlorophyll breaks down, the other pigments that weren’t visible to the human eye before are now on full display.

Every tree has a different combination of pigments, which gives leaves their unique colors: Yellow leaves contain xanthophyll, orange leaves contain carotene, and red leaves contain anthocyanin.

September is National What Day?

September is most known for Labor Day, a great time to show your appreciation for your own employees or the customers you know work hard year-round themselves. You can really show your appreciation with something like a nice pair of headphones or an Amazon Echo Dot.

National Yoga Month occurs in September, as well. This makes it the perfect month to offer your clients exercise mats or even workout apparel.

September is also National Preparedness Month, a month set aside to raise awareness for how to prepare for natural disasters or terrorist attacks. Items like first aid kits or survival kits could be useful during this month. Other awareness events occurring in September include:
