I wrote last fall that high-density
apples yield early and prolifically, but that you have to commit to
lots of summer
pruning and training
to make that dream a reality. With fruits well set on trees that
are going to produce this year, the plants are now turning their energy
to shoot growth. Time to honor my commitment and give those dwarf
trees some TLC.
The first thing I'm
looking for at this time of year is double headers like the one shown
to the left. Since the nursery I bought the trees from headed
(cut the tops off) the apples before shipping them, multiple shoots
have a tendency to spring up right below the cut. I want one
central leader, so I pick my favorite, then rip the other one(s) off.
Side shoots are also
starting to elongate at this time of year, and many varieties have a
tendency to send that growth vertically, straight to the sun. I
don't want side branches competing with my central leader, and I also
want to make the branches as horizontal as possible to promote early
fruiting, so I took another pass through the planting to tie down
branches so they look like the photo to the right.
Even if you don't have a
dwarf apple tree that you're pruning in a high density system, now's a
great season to spend a little time with your fruit trees. Weighing
down a few branches now or yanking off watersprouts before they harden
off really pays off by prompting the tree to put all of its energy into
the wood you want. Just remember that for most trees, you won't
want to make the side branches completely horizontal the way I'm doing
for my high-density apples --- that's a way of keeping the plants
compact and tempting out early fruits at the expense of a large canopy
and longevity.
