Why does cutting off the tip of the main stem ofa plant often result in the plant growing bushier?

Answer 1

By breaking of apical dominance.

Thank you. The apex of plants produces auxins, or phytohormones, which control the growth of lateral branches and cause apical dominance. Pruning the apical portions of the plant counteracts the effects of apical dominance and results in bushy growth of the plants.

Apical pruning, which involves cutting off the tip of the main stem of a plant, eliminates apical dominance and permits lateral buds to grow and develop into branches, giving the plant a bushier appearance as more branches emerge from the lateral buds.
