Why do leaves fall off trees in summer

What causes the leaves to fall off of the tree?

The short answer is that leaves fall off trees when they aren’t doing their job any more. A leaf’s job is to turn sunlight into food for the tree.

Why do some trees drop their leaves in response to the changing temperatures during fall?

As changing climate and light conditions of autumn evolve, hormones within trees change too. The most notable is auxin.

Why do leaves turn red in summer?

In summer, extremes of high heat followed by cooler temperatures cause nutrient imbalances. Anything that dehydrates roots and plant tissues can lead to red leaves. Poor soil drainage and compacted soil, often prevalent in urban areas, limit the flow of necessary water and nutrients between roots and leaves.

Why are the trees changing color in July?

The Short Answer: As summer fades into fall, the days start getting shorter and there is less sunlight. This is a signal for the leaf to prepare for winter and to stop making chlorophyll. Once this happens, the green color starts to fade and the reds, oranges, and yellows become visible.

Losing leaves helps the tree to retain water during in the winter and means that it needs less energy to stay alive. The fallen leaves help to add nutrients to the soil.

What happens to leaves when they fall?

Fallen leaves are recycled. After a leave has reached the ground, it begins to break down (with the help of animals, bacteria, and fungi), creating a layer of decaying organic material at the base of the tree. The leaf matter is converted back into simple carbon dioxide and water.
