Attended a course on pruning fruit trees.
Normally the recommendation in gardening books is to prune in winter, when the
tree is dormant, which is what I used to do in past years.
Learned from the course that if we would
like to control the size of the tree, so that the branches are not too long, it
is important to prune in summer, after fruit harvest.
The concept is, the tree base on the amount
of leaves there is, will grow the root system accordingly. If we prune in
winter, the root system had time to grow big, so when spring comes, the stored
energy sees the need to grow branches and leaves to be equal, will push out a lot of
vertical suckers.
Whereas if we prune in summer, the size of
the root system will grow in proportion to the top, so that next spring, the
energy will be used to grow flowers.
