Canopy

The canopy of a tree is the engine that drives survival. Trees convert light into energy via photosynthesis. I will spare the details about electron transfer and ATP, remember those terms? Anyhow, the larger the tree, the more energy they require. Optimum health is achieved when a full canopy develops. Over-planting and crowding of landscape trees, compromise plant health. Proper spacing is important for a tree to be able to develop its proper shape and to utilize as much sunshine as possible.
It is important to thin areas to allow certain trees to mature and thrive. Overcrowded areas can eventually become treeless, as no single plant is allowed to be healthy. In the presence of intense competition with other trees, plants shoot toward the sunshine, never developing a proper canopy.
