Plum & Apple Grafts at 3 weeks. 4.11.15

Ember Plum Graft.  4.11.15

Redfield Apple Graft.  4.11.15

The first of the Fedco scion are out o dormancy.  I grafted these 3.21.15.  It's too early to say for certain, that they fully took.  I think they probably have.

The stems can contain enough reserve carbohydrate and moisture,  for some bud expansion.  I'll feel more secure when leaves are fully unfurled.

These are about 3 weeks.  Pretty good. 

I did bring these inside during the evenings, the past few days.  I read warmer temperatures encourage cambium merging and improve the rate of take.  That may also be why they broke dormancy.  The outdoor grafts on the in-ground trees, are expected to be slower.

Apple Propagation. Some Experiments. 11.24.15

Apple graft removed from trunk of rootstock. 11.25.14

Apple sucker removed from trunk of rootstock.  11.25.14

 In March, I grafted a NOID apple from my yard, onto sprouts that had emanated from a culled Golden Delicious apple tree.  I don't know the rootstock - the tree was in the semidwarf range.  In 7 years, it gave no apples, and it had recurrent blight problems.  So I cut it down. 

This Spring, I saw sprouts that had grown up from the old rootstock.  I chose 2, and grafted a NOID columnar apple onto them.  The were 6 inches apart.  I thought, if only one grew, that was OK.  If both grew, I could cut off the smaller one.

Today, I dug out the smaller one.  These sprouts turned out to be attacked to the trunk, not more distant roots.  It was difficult to remove the grafted sprout with any intact roots.

It will be interesting to see if, in removing this one, I killed the other one.  It was more distal, so the taller one may have lost its main roots.  I did not dig further to find out.  It seems fairly attached to something in the soil.

There was also a small sprout.  I was not gentle, did not mean to keep it.  It looks viable, so I'll give it a try.

I have seen apples and peaches with this few roots survive and grow.  They are almost like a big cutting, but with a few roots already growing.  The most difficult part with cuttings is getting through the stage of initiating roots.  Once the first roots grow, they serve as the start for many roots.

Apple experiments, potted up.  11.25.14

These are now potted up.  I'll try not to expose them to too severe of a freeze.  They may take a while to grow.  If the rootstock heals and grows, I can use it for future grafting.

Rootstocks

Looking into backyard orchard culture information, I want to keep track of my rootstocks. I'm not sure if this information will be useful, but if I don't put it here, I wont have it. This information is not available for most of our existing trees, unless I kept the labels somewhere. Here are a few that I found:

Hollywood Plum - Marianna 2624
Shiro Plum - Marianna 2624
Surefire Cherry - Gisela 5
Combo Asian Pear - OHF97

Prior trees, if current catalog info is still correct -

El Dorado Peach - Lovell
Tri-Lite Peach-plum - Lovell

I have recepits that show:

Liberty Apple - M27
Jonagold Apple - M27
Garden Gold Peach - Lovell
Flavor Delight APrium - Citation

According to Raintree, Lovell is a "seed-grown standard peach rootstock has proven dependable and may develop a longer lived tree with better disease resistance and hardiness than other peach rootstocks. " Dave Wilson Nurseries states that Lovell is "slightly more resistant to wet conditions than Nemaguard but prefers well-drained soils, slightly more resistant to bacterial canker than Nemaguard" but also "susceptible to root-knot and root-lesion nematodes and to oak-root fungus, some what susceptible to bacterial canker"

According to fruitforum.net, Gisela 5 is a rootstock of choice for growers and makes a compact tree for gardens, although that information referred to sweet cherries.

According to the Dave Wilson Nurseries label, Citation"Resists root-knot nematodes. Induces heavy bearing at a young age. Trees on Citation may be held to any desired height by summer pruning"

As for the Marianna, Dave Wilson Nurseries states "slightly dwarfing, moderately resistant to Phytophthora crown and root rot and oak root fungus, tolerates wet soils, root-knot nematode resistant" but tends to lean, shallow roots the first few years, very susceptible to bacterial canker... susceptible to crown gall..." Raintree states "It will produce a semidwarf tree maintained from 10 to 15 feet tall. It does very well on wet soils and tolerates a variety of soils. It is compatible as an understock for plums, peaches and some almonds and apricots."

Dave Wilson Nurseries states that OHF-97 "...vigorous, widely adapted, disease-resistant. Winter hardy, tolerant of wet soils."
