Which of the following practices is most effective in promoting the bushier growth of a plant?

  • A: Increasing light intensity from all directions.
  • B: Pruning or pinching back the shoot tip.
  • C: Providing more water and nutrients.
  • D: Removing lower leaves from the stem.

Explanation

Pruning or pinching back the shoot tip removes the active apical bud, thereby disrupting apical dominance and allowing axillary buds to break dormancy and develop into lateral shoots, leading to a bushier plant appearance.
