In horticulture, notching and nicking are techniques used to manipulate plant growth, particularly in fruit trees and ornamental plants. Here’s how they differ:

Key Difference
Notching (above bud) = Promotes growth.
Nicking (below bud) = Restricts growth.





1. Notching

Definition: A small cut or removal of a section of bark (without damaging the cambium layer) just above a bud or node.

Purpose: Encourages bud break and new shoot growth by disrupting the downward flow of auxins (growth hormones).

Used For: Promoting branching, canopy shaping, and encouraging lateral growth.

Common Plants: Apple, pear, citrus, and some ornamental trees.





2. Nicking

Definition: A shallow cut made just below a bud or node, without removing the bark completely.

Purpose: Prevents bud activation by allowing auxins to accumulate above the cut.

Used For: Controlling unwanted shoot development and regulating plant shape.

Common Plants: Often used in rootstock management and plant training.
