Detailed explanation-1: -A tree becomes mature when it starts producing fruits or flowers. This is when the tree is at its most productive. How long it will stay productive depends on the species. A typical English oak tree starts producing acorns at around 40 years old, peaking in productivity around 80-120 years.
Detailed explanation-2: -Common Tree Measurements Small trees have a DBH of up to 14 inches; medium trees 15-19 inches, and large trees 20 inches or more. In the nursery trade, we describe trees in terms of their caliper, which is the measure of diameter; and depends upon plant size made at a point 6-12 inches above the ground.
Detailed explanation-3: -Most landscaping professionals recommend that you leave at least 10 feet between small trees and at least 30 to 50 feet between large trees. Medium-sized trees can fare well with a distance of 20 feet between them.
