Trees give off oxygen that we need to breathe. Trees reduce the amount of storm water runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding. Many species of wildlife depend on trees for habitat. Trees provide food, protection, and homes for many birds and mammals.

Why it is important to have a nursery in propagating trees and fruit bearing trees?

Why is that? For most species, tree nurseries are needed because: sowing in seed trays or nursery seed beds with a suitable germination medium (B 42) generally gives a higher germination percentage and better seedling root establishment than in ordinary soil; nursery plants need not compete with other vegetation; and.

Why do you need to propagate fruit bearing trees?

Therefore, from the orchard grower or gardener's point of view, it is preferable to propagate fruit cultivars vegetatively in order to ensure reliability. This involves taking a cutting (or scion) of wood from a desirable parent tree which is then grown on to produce a new plant or "clone" of the original.
