pruning is only necessary to shape trees or to reduce fruiting levels. Or to allow light in.
Most of the above are not the norm. Rather more irregularly required. I’d suggest that you were shown how to allow light in or reduce the crop size. Neither of which is necessary every season.
to prune or not to prune ?
my neighbour is a brilliant tree pruner – witness his dozen 40 y.o. fruit trees all bearing copious amounts of fruit. he comes round here and stands, points and shakes his head. i think the only way i’ll learn is by doing my apprendiceship with the shears.
btw – how do you prune a fig tree?
Term: Water Shoots
Definition:
Fast growing shoots that usually arise around the site of pruning cuts or other damage.
in roses for example: New water shoots have to stay, even if they shoot up the middle. Water shoots are the new life and future of the plant.
“Large numbers of water shoots that emerge after winter pruning on semidwarfing and vigorous apple trees modify light climate within the tree canopy. Continuous measurements of illumination during the growing season on 11-year old apple trees revealed that water shoots decreased illumination about 50 % in the inner part of the tree canopies. Removing water shoots in the summer increased greatly light levels and improved the fruit colour. The question arises if water shoots that can bear up to 20 % of foliage surface on the tree contribute directly in the supplying of carbohydrates to fruitlets.
To solve this problem 14 CO2 was administered to mature leaves on water shoots and then the movement of radioactive assimilates was traced by radioanalytical methods.
It was found that radioactive assimilates are not translocated directly from the water shoots to fruitlets situated on neighbouring spurs. These assimilates are taken up by growing water shoot tips and incorporated in the bark and wood of main limbs near the place of their production. Removing tips of water shoots or the leaves adjacent to fruitlets did not change the pattern of assimilate distribution. Tracing of the vascular system of apple shoots was performed using different dyes as markers. The pattern of the vascular connection has been documented by figures, photographs and graphs. “
From the above you may ascertain that removing some watershoots may improve fruit colour and may help with setting fruiting spurs in some trees. However, the life of the tree is also more important than getting it to bear heavy crops especially in early years. In some types of fruiting trees it takes years of setting up a fruit bearing framework of branches so that good continuous cropping can continue for many more.
Getting back to citrus, being evergreen and a tree type wich hangs on to its leaves, it stands t reason that it needs all of them. Citrus benefit best by hedging. Many citrus farmers regularly bring the tops of the trees down but this is due to the fact that pickers don’t like climbing ladders with heavy bags of fruit. Many also get me to apply a dwarfing virus.
