Many plants, including trees, angle their leaves towards the sunlight through the day with the help of this effect. At night, without sunlight, the energy needed to do this is no longer generated, so the pressure inside the cells may drop. This means a trees branches will drop to a ‘resting’ position.What happens to leaves after 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.
What do plants do in cold weather when the leaves fall off?Answer: Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant.

How do you speed up the decomposition of a leaf?
To promote decomposition, mix leaves with grass clippings or other materials high in nitrogen. If possible, shred the leaves prior to composting. The smaller the size of the material, the faster it will decompose.
Should I put leaves in my garden in the fall?
