Absolutely love this! If you live in a warmer climate, such as California or Florida, why not hold your Thanksgiving dinner outside? You could enjoy the cool fall air and the beautiful autumn leaves.
In this Beer Garden Table Makeover and Alfresco Thanksgiving project, they first refinished an old beer table. Once that was finished, the table was decorated with a vase of autumn leaves, 2 pumpkins, and the rest you see in the picture. This can be great family activity everyone will enjoy. Very Thankgiving-ish looking and a great place for outdoor enthusiasts to dine.
Leaves get their green color from chlorophyll, contained in cells within the leaves. Chlorophyll is necessary for photosynthesis, it captures sunlight to produce plant sugars. As days grow shorter and temperatures cool in the fall, trees stop producing chlorophyll, some earlier than others.
Without chlorophyll to capture sunlight, other pigments contained in the cells of leaves become more visible. These other pigments are called accessory pigments, they include carotenoids and anthocyanins.
Carotenoids absorb blue and violet light and reflect yellow and green wavelengths, which is why they appear yellow to the human eye.
Anthocyanins absorb blue and green light and reflect red wavelengths, which is why they appear red to the human eye. These accessory pigments are present in leaves all year long and some accumulate higher than others in the fall.
Why Are The Trees More Colorful Some Years?
The amount of sunlight and temperature conditions determine if trees will turn more colorful in the fall. Trees that grow at higher elevations or towards the poles may turn red and yellow earlier than those growing closer to the equator, which is why we see some trees with brilliant colors while others nearby are still green.
Also, years with abundant rainfall will produce more colorful fall leaves, while dryer, or even drought conditions will cause trees to skip their brilliant color phase in the fall.
