Trial shows good growth from old apple ground treatments

September 2020 | Susie Murphy-White | Future Orchards® / APAL article

Apple replant sites can suppress young-tree growth and delay the return from redevelopment. This APAL Future Orchards® article reports on work led by Susie Murphy-White examining treatments applied to old apple ground before replanting.

The trial is valuable because it follows establishment performance in a commercial context and compares practical pre-plant approaches rather than relying only on laboratory indicators. Early differences in tree growth can translate into meaningful differences in canopy fill, management cost and time to commercial cropping.

The article reinforces the importance of understanding the history and condition of a redevelopment site. Replant disease is only one possible constraint, so soil structure, nutrition, drainage, old-root removal and the consistency of treatment application remain important considerations.

For growers preparing a replant block, the resource provides a field-based example of how treatments can be tested and monitored before committing to a whole-orchard strategy.
