During the Fall, leaves from trees fall to the ground and the trees become dormant. Over time, those leaves on the ground start to shrink and turn brown. Then, they dry up. Why? It is all because the leaf is not receiving or making water or nutrients. When a leaf is attached to a tree or plant, it converts sunlight into energy for the plant through photosynthesis. The leaf also gets water from the plant to stay alive. When the plant or tree is going dormant, it loses all of it’s leaves and cuts off the water and nutrients flow to the leaf. Because the leaf is not getting water, it starts to dry up. But, in Spring, the leaves grow back again and the leaves are green and healthy now!
