Itâs a fascinating new way of looking at fruit trees, at the bigger picture of how trees operate in the forest, and the natural shape theyâre inclined to take on. Rather than forcing the tree into predetermined shape, this approach aims to train the tree based on fundamental understanding of what processes influence a treeâs growth i.e. working with nature rather than against it. It is particularly suited to apple trees but the principles can be adapted to the care of many fruit trees, to allow for a more harmonious and natural approach to pruning.
The workshop also focused on summer vs winter pruning. Summer pruning reduces photosynthesis, and thereby reduces the capacity for new growth the following year, versus winter pruning which encourages new growth in spring.
The timing for pruning fruit trees in New Zealand can vary depending on the type of fruit tree and the goal of the pruning.
Summer pruning is especially useful for containing growth (where the tree is being trained as a cordon or espalier, for example, or outgrowing the space available).
Summer pruning also encourages the dormant buds at the base of branches to quickly form fruiting spurs, increasing yield the following season.
Traditional winter pruning encourages growth at the expense of fruit â great in the early years when the goal is to establish a good branch framework and there is a lot of growth to work with, but not so good once the tree has become established.
There are some more notes on summer pruning here.
