They fertilize grass so it will grow. These Suburbanites must be relieved in the summer when we cut back on rain and crank up the heat. That surely slows plant growth and saves them a lot of work. At least they kept the trees. That was a sheer stroke of genius, if I do say so myself.
Trees grow leaves in the spring to provide nourishment, beauty, and shade all summer long.
In the autumn, leaves fall to the ground and form a natural blanket to keep moisture in the soil and protect the roots of trees and bushes. Plus, as they rot, leaves form compost to enhance the soil. It's the natural circle of life and one of my best ideas. The Suburbanites have drawn a new circle. When the leaves fall, they rake them in great piles and pay to haul them away too.
