Training Ginkgo Trees as Large Bonsai. 4.9.17

Ginkgo Tree in Chengdu, China.  10/2013

Ginkgo Trees in Chengdu, China.  10/2013

In 2013, we went to China and visited historic places including some palaces and monasteries.  These Ginkgo biloba specimens were trained like bonsai trees, but in-ground and larger.  Probably quite old.

We wanted to reproduce a similar idea in our garden, using ginkgo trees that I grew from seeds.  They are about 10 years old, planted in a mixed shrub and perennial bed.  Today, I began training them as the start of making our own bonsai-type trees.  I selected branches at level of the tree.  I  pruned then long stems from each branch leaving 1-3 buds per spur.  Then I tied the branches to poles - mainly prunings from buddleia and plum - and lowered the pole-tied branches to a horizontal position, tying them to bricks.  Some, I turned to a chosen lateral orientation, as well as lowering them vertically, so they would be somewhat distributed around the trunk.

It turned out, this relatively young ginkgo wood is rather pliable, more so than willow, I think.  It bends a bit like lead.  None of them broke, despite some severe bending at very different angles from what they started with.

First Stage of Training Ginkgo Tree.  4.9.17

I think this was a good time to start, with buds beginning to swell for Spring growth, but no actual growth yet.  The sap is running, which may have made the branches more pliable.  Even branches as thick as my thumb bent readily, although I was careful and bent them slowly.

The plan is to allow growth along each branch, maybe to 3 or 4 nodes, then pinch the apex of each spur so that they branch more tightly. 

I don't expect to make trees as majestic looking as the ones we saw in China.  That might take decades, which I don't expect to have.  But we might have something interesting in a couple of years.

Near the tops of the trees, I did leave young growth to extend longer with plan to bend to horizontal positions next year.  The maximum planned height is about 7 or 8 feet tall.

Fruit Bloom Diary. 4.9.17

 Here is my fruit tree bloom diary as of today. 

Completed Blooming and Petals Fallen.
Crimson Pointe Plum.

Past Peak but Many Blossoms Present.
Sweet Treat hybrid plum (pluerry).
Nadia hybrid plum (Asian plum x cherry).
Hollywood (Asian plum).

Late Peak.
Methley (Asian Plum).
Unknown Asian Plum.

Peak.
Hanska (Hybrid American x Asian Plum).
Toka (Hybrid American x Asian Plum).
Ember (Hybrid American x Asian Plum).
LaCrescent (Hybrid American x Asian Plum) .
Shiro (Asian Plum)

Rare blossoms open, most not open yet.
Possibly, Green Gage Plum - small green euro plum.

Toka Plum.  4.9.17

Vandalay Cherry.

Hanska Plum.  4.9.17

Hamese Asian Pear.
Hosui Asian Pear.

Most of the pears are not open yet.
None of the apples are open so far.
Most of the sweet cherries are not open yet.
None of the pie cherries are close to opening.
Pawpaws have swelling buds but not close to open flowers yet.

I've read mixed reports on pollination among the American X Asian plum hybrids.  Most state that Hanska and Ember are poor pollinators for the others, while Toka is a good pollinator.  I'm not sure about LaCrescent.  I have not read about the effectiveness of Asian plums with these, such as Shiro which had the same bloom time for me, or Hollywood and Methley, which seem to overlap but not perfectly.

When I originally obtained the American X Asian hybrid plum grafts, one of my goals was to see if they bloomed later than Asian plums, and therefore less risk for damage by late frost.  That hypothesis was correct.  Since this is the first year for massive bloom, I don't know yet if they will actually provide fruit here, or what those fruits will be like.

Sweet Treat and Nadia are new interspecific hybrids, and their pollination requirements are not well known, especially in this area.  With early overlap by Crimson Pointe, mid overlap by Hollywood, Methley, and the unknown Asian Plum, and late overlap by Shiro, the bloom times are covered.  Whether any of those will be genetically compatible pollinators, I hope we learn soon.  I won't know specifically which ones, but I might learn if we have those needs covered.

LaCrescent Plum.  4.9.17

 So far my wild plum hasn't even made buds.  I don't know if it is skipping a year, or if it is just going to be a lot later.  If so, and no fruit, it might be a candidate for removal.

Planting Two Grafted Chestnut Saplings. 4.4.17

Grafted Chestnut Saplings.  4.4.17

The two grafted chestnut trees from Raintree arrived yesterday, so I planted them.  The smaller one doesn't look like much.  The larger one is OK although the pruning was kind of harsh.  I guess that is needed for shipping.  The varieties are Maraval and Marigoule, Euro/Japanese hybrids.  They have deer fencing, and I will add the vole barrier tomorrow.

It's always amazing to me that bare root trees can survive, take off and grow.  I hope these do the same.

This completes the various things I wanted to do with the huge area of blackberries that I spent a year clearing.  Now there are 3 chestnut trees planted, and a dawn redwood.  The forest edge has perennials that I salvaged / rescued from the old yard, and the Hawthorn trees have grafts of Chinese Haw, Quince, and Asian pears, for fun/.  The back is planted with a row of Cypress, for privacy, reduce invasion from wild blackberries, and to prevent erosion.

Flowers. 4.4.17

Charlotte Peach.  4.4.17

Daffodils in flower border.  4.4.17

 Lots of flowers blooming.  If the peaches and plums didn't bear fruit, they would still be worth growing for their flowers.  Most of the daffodils were ones that I recovered from the old yard.  They established and are flourishing.  Some are from random acts of daffodil bulb planting that I do each fall.

Fruit Tree Blooming Notes. 4.4.17

Methley Plum.  4.4.17

Hollywood Plum.  4.4.17

 I'm recording the bloom dates for my fruit trees.  For future decisions, I want to know if some bloom too early, and are exposed to frost.  For pollination and multigrafts, it doesn't help if one is finished before the polleniing variety starts.

Here's where they are now.  At my place in Battleground, only the Asian plums and peaches are blooming.

Peak or past peak blooming:
Crimson Pointe ornamental plum.

Peak Blooming:
Hollywood Plum.
Methley Plum.
Sweet Treat Pluerry.
Nadia Plum Cherry Hybrid.

Early Open with a few flowers Blooming:
Shiro Plum - barely started.
LaCrescent hybrid Plum.
Charlotte Peach.  Almost peak blooming.
Mary Jane Peach.

Buds present and swelling but not open:
Hanska hybrid plum.
Ember hybrid plum.
Toka hybrid plum.

I have Hollywood on Toka.  I think I'll remove it.  Hollywood is way ahead of Toka, and is much more vigorous.  I have several other starts or grafts of Hollywood, so removing it is no loss.  Except I hate to remove a successful graft of my own doing.

Most of the cherries have swelling flower buds, as do most of the the pawpaws, Asian pears, and some apples. 

There are tiny insects moving from flower to flower in the plum and peach trees.  I imagine those are pollinating insects.  I cut sections from the unknown plum tree, and Crimson Pointe, and attached them to the other trees, as pollen sources.  I also hand pollinated a little, for Nadia and Sweet Treat.  I doubt that will have much impact, but it's not difficult to do.
