So many trees grow in the parks and on the roadside, How do they manage to add fertilizers to so many trees?

Leaves that fall from the trees act as natural fertilizers. They gradually get absorbed into the soil by the water, get decomposed, and become fertilizer.

2. Why do gardeners plow the garden?

With the help of a spade, the gardener turns the soil so that is can ‘breath’. It is believed that plowing helps the plants to grow as more carbo dioxide is available from the soil. But there is a problem with this method. When the soil is turned, the weeds, sleeping quietly below the surface of the soil, wake up. After plowing they begin to grow as well and then we begin with the process of weeding!
