Comparison of flower removal strategies in young trees for growth response

2017 | Prepared by Jabbar Khan (Fruit Growers Victoria) and Angus Crawford (APAL) | Future Orchards® Southern Victoria trial report

This Southern Victoria trial compares flower-removal strategies in young apple trees and their effect on vegetative growth. The work addresses a common establishment trade-off: allowing young trees to carry an early crop can provide income, but excessive reproductive demand may slow canopy development and delay the point at which the orchard reaches full productive capacity.

The trial evaluates different approaches to removing flowers early in the season so that tree resources can be directed towards extension growth and canopy establishment. The resource is particularly relevant to intensive orchard systems where the commercial objective is to fill the allotted canopy space rapidly while still making sensible decisions about early cropping.

For growers, the report provides a structured way to think about early crop removal: compare growth response between treatments, consider the value of an early crop against the value of faster canopy development, and use measured tree growth rather than habit alone to guide establishment decisions.
