Ratio of trees to grass for healthy lawn?

[srinivas]

The ideal ratio of trees to grass for a healthy lawn depends on various factors such as the type of tree, the size of the lawn, and the amount of sunlight it receives. There is no specific ratio that applies to all lawns, but as a general rule, it is recommended to plant one large tree or several smaller trees per 1000 square feet of lawn.
This allows for sufficient sunlight to reach the grass while also providing shade and shelter. Additionally, it is important to maintain the trees and grass properly to ensure their health and longevity.
