Pruning a Gravenstein Apple Tree. 11 Apr 24.

Continuing Spring pruning.   Last fall, I had the deer fencing removed from around the Gravenstein apple tree.  It's big enough now, I think I can keep branches above convenient, deer salad bar height.   It's a lot easier to maintain an unfenced tree, thin fruit, pick fruit, prune, and mow, if the deer cage is gone.

Here is the after photo.


The goals for fruit trees in deer country are the same as everywhere else, but also to keep branches out of convenient reach for deer browsing,  I say "convenient" because a motivated deer can stretch really high, or can pull down willow branches.  But I have not had a problem when I kept the branches and leaves up high.

I like to have open center, for air circulation and for sunshine throughout the tree.  I don't like branches that rub on each other, so one of those has to go.

Bearing branches should not be long and willowy.  Even half inch branch at 10 feet high can droop to a few feet from the ground.  The  you get this -



 I have been aiming for young  bearing branches about a foot or two, off the heftier scaffold branches,  This also prevents excessive weight of too many apples, from breaking the limbs.

This tree has a pollinating graft that blooms at the same time.  I used Airlie Red Flesh, which has pink, almost red flowers.


That compares to the pale, almost-white flowers of Gravenstein.


The label had fallen off.  By making the original choice of a color coded variety, when I grafted on the original pollinating scion, It helped a lot in determining that important branch to keep.  In this case, the branch was drooping.  Instead of cutting it off, I tied it vertically to create a taller scaffold branch.

I graft on pollinating varieties partly for the fun, and to try different varieties, but also because honeybees have become less common.  Tiny pollinating bees are all over here, but seem to stay mostly within a tree's branches, rather than flying tree to tree.  I think having a different variety within a tree, whose bloom time overlaps with the main variety, increases the chances of successful pollination. 

Aren't they beautiful?  And they smell like apple blossoms.

Also, if a branch looks good but needs to be lifted or shifted to fill in a dead space, I tie it with cotton clothesline rope.  It's strong, easy to tie good knots (unlike plastic string), biodegradable but lasts a few years outside.

I did cut a couple of scaffolding branches that were too high or too low, or crossing another.

I cut off any buds or twigs below about six feet high, so as not to get a deer started and wanting more.

Here is the before photo.



Power Secateurs For Pruning. 11 Apr 24.

 These helped a lot with today's pruning.


I think I got about three times as much done, as I would have otherwise.  Also, they cut through branches that would have been too difficult with my hand secateurs.  They extended my reach a bit, too.

Bush Cherry Carmine Jewel Blooming. 11 Apr 24.

 A few years ago, I tried to grow a bush cherry.  I think it was either the variety Romeo or Juliet.  They did not survive, due to some sort of cherry rust disease.  That also happened with a bush Nanking cherry.

In Spring 2023, I bought a Carmine Jewel bush cherry to try yet again.  So far, so good.  It grew through the summer, and survived the winter.  Now it's blooming.  Based on those blossoms, there could be a lot of cherries for such a small bush.




This is located in the rose garden / duck yard.  

First Dahlia Emerging. 11Apr 24.

 The first of the big, store-bought dahlias has started to emerge now.


It's in this container to get growth started.  Along with another tuber.   Next I'll plant it in it's own pot so it can get growing before going into its final location.

Pruning An Asian Pear Multigraft, In Bloom. 11 Apr 24.

 This Asian pear is pretty productive.  I forget the three or four varieties.  It grows too tall to manage the high growth - pruning, thinning, picking.  I cut back the top last year.  I waited until bloom so I can prune while preserving some of this year's crop.  It only needs to make a few bowls of fruit. maybe a batch to can.

I cut out the top again, shortening the trunk by about 18 more inches.  I shortened most of the branches back to stronger wood.  I don't want long, willowy branches with too much heavy fruit that break off.  I opened up the center some more, to bring more sunlight into the tree.


I think this size and density of blossoms will give us some nice fruit and enough of it. The branches are all within easy reach for thinning fruit, and picking.  It also sets up a better shape so that pruning next year will be simplified.

I have not pruned trees while in bloom, in the past.  It makes sense to me, but isn't what is usually recommended.  So we will see what happens.  Rainy season is about over, so this timing will give the cut ends a good chance to start sealing over, so maybe prevent disease from entering those wounds.  Vigorous growth is about to commence, which should be good timing.  I like being able to judge which branches to cut, based on the flowers now on those limbs.
