Topping
An agricultural practice of removing the terminal bud or the top part of a plant's main stem to stop vertical growth and stimulate side development.

Topping is performed to redirect the plant's energy and nutrients towards fruit development or branching rather than vegetative growth. This technique is widely used in crops like tobacco, tomatoes, and certain ornamental plants to improve yield quality and consistency.
The timing is crucial: it is typically done once the plant reaches a desired height or has set a specific number of flowers. If performed too late, the plant will have already exhausted its resources; if performed too early, the plant may fail to reach its full productive potential.
Common mistakes involve removing too many leaves, which impairs photosynthesis, or using blunt tools that cause ragged wounds prone to fungal infections. Growers should also ensure that weather conditions are dry and favorable to prevent disease spread through the fresh cuts.
