Apple Grafts. Progress Report. 7.4.2020

These are the apple varieties that I grafted onto either Bud-9 or Geneva-222 highly dwarfing rootstocks.  Most are on Bud-9 but I tried to use Geneva 222 on ones that I thought might have too little vigor.  On taking of the tape, there was slight constriction of stem girth but not severe, and not girdling.  Going by memory, which isn't perfect, here is a list.

Here are the varieties that took and grew quickly:
Jonagold - most vigorous. (Bud-9)
Jonared - less vigorous (Geneva-222)
Gravenstein -less vigorous (that was a surprise) (Bud-9)
Winter Banana - very vigorous (Bud-9)
Black Oxford - very vigorous (Bud-9)
Macoun - somewhat vigorous (Bud-9)
Beni Shogun Fuji - less vigorous (Geneva-222)
Porter - quite vigorous. (Bud-9)

I tried a tiny graft of Pristine on Geneva-222.  This was the only cleft graft.  The growth was vigorous, but when I removed the binding tape, the graft broke off.

I tried a pear on Winter Banana intergraft on Bud-9.  That grew a little but died.
I tried pears on Amelanchier.  Those failed.
I tried pear on Chinese haw - that appears to have taken and is growing somewhat vigorously.

Grafting follow up. Cleft, Whip and Tongue, Bud Grafting. 8.31.14

Cerasifolia Plum graft.  Grafted late May 2014.  8.31.14
 This is a follow up on a few of the grafts I've done.  The lilac bud grafts all appear to have taken.  The buds are plump and green and look similar to the "native" buds on the stock.  They have a good start for winter.

Most of the earlier bud grafts, from late May, healed and merged with the stock, and did not grow.  That is pretty much as I expected.  They look ready for winter.  For late winter pruning, the plan is to cut the stock above the buds, so that there is no auxin - inhibition and they take off and grow next Spring.

Two of the May plum bud grafts took off and grew like crazy.  The cerasifolia graft shows up nicely against the green foliage of the stock tree.  Hollywood would do the same.  i wonder if these rapidly grown grafts will bloom next year.  If they do, that will be awesome.

Sour Cherry Bud Graft.  Grafted July 2014.  8.31.14

Sweet Cherry Bud Grafts.  Grafted July 2014.  8.31.14
 The sour cherry and sweet cherry bud grafts mostly appear to have taken.  Possibly, all of them.  Most look about the same as the native buds on the stock trees.  The sides of the T-slice tend to curl back as the bud and tree callous and merge.  The top of the T seems to callous and merge without peeling back.

Last year's cleft graft on the Asian Pears, have almost completely healed over.  I was interested to see if the expose wood, would be a problem.  It looks like there is not problem.  At this rate, next year they will be completely filled in, leaving a visible graft but no open wood.

This year's Whip/Tongue grafts on the Asian pears, both the Asian pears I grafted and the European pears, have all healed over completely.  Growth surprised me - most had 2 to 3 feet of growth.  That is faster than the cleft grafts, in general.  Not a good test, but with no exposed wood, and instant, full cambium connection, whip/tongue in theory could give a faster start.

This is only a few of the many grafts I did this year.  All plum grafts took, all pear and apple grafts took.  Only one of the whip/tongue grafts on lilacs took.  It looks like all of the bud grafts on lilac took, so maybe that's the best method for them.

Grafting is amazing.  I can't believe it works.  It should - it's been done for thousands of years.  But it's still amazing.

Asian Pear Grafts. 4.16.14

Cleft Graft Asian Pear, 1 year later
 The cleft grafted asian pears from last year are growing nicely.  The callous tissue is irregular in these grafts,  but that doesn't seem to affect the growth.  The new growth is vigorous and healthy appearing.  It's a vigorous as the growth of the stock variety.

Unfortunately I didn't tag with variety name.  Once they fruit I can figure it out.

All of the new Asian pear grafts have new growth.  Some as swelling green buds.  Some with new leaves and stems.

I've been reading up on when to remove the tape.  Leave on too long and stem is girdled.  Take off too soon and they might come apart.  Looks like I should remove in May, with about 2 months of growth.

Note for next year:  take only scion with no flower buds.  Blooming seems to set back the vegetative growth, significantly.

Fruit Tree Grafting. Progress Report. 3.9.14

Asian pear graft.  Hamese.  Whip and Tongue.

Asian pear graft.  Mishirasu.  Whip and Tongue.
 Some of the new grafts have swelling buds.  Probably flower buds.

I don't think it's beneficial to let them fruit the first year.  Wood may not be strong enough for the weight of the fruit.  Bearing would decrease stem growth.  I think it's OK to allow blooming, which might also help pollinate the established branches and 1-year-old grafts.

It looks like a couple of the 1-year-old grafts might also bloom.  I might let those bear fruit so I see what they are.  Forgot to label them last year.

The Hosui stock had buds in various states of development.  I want the grafted varieties to pollinize the Hosui, and vice versa, for better yield.  Or for yield at all.

Hosui bud.  This is the stock.  The framework I am adding more varieties to.

Fruit Tree Grafting. 2.25.14

I've been watching the Calendar for grafting time.  I think this is grafting season now for apples and pears.  About the same time as I did last year, which was successful.

Today I added a pollinator variety to the little Honeycrisp, another to the one year old Sutton's Beauty, and one to the one year old Esopus Spitzenberg.  The pollinator varieties are old varieties.

I also added 3 varieties of Asian pear to the 2 year old Hosui, and 2 unknown varieties of European pear to the unknown variety of Asian pear.  This is for pollination.  Also I want to keep those varieties, if we move to the Battleground place.  I prefer more varieties, on the trees already there, than adding more trees.  We don't need a tree-full of each cultivar.  Just a branch for a couple bowls of fruit when each ripens.

Graafting Supplies and Scion Wood

Last year I did cleft grafting on existing trees.  I thought I was too uncoordinated to safely do whip & tongue grafting.  This time I did do whip & tongue grafting.  The saddle grafts all took, and some grew surprisingly fast.  But a cleft graft exposes open wound on each side, which dies and needs to be overgrown by new wood.   The whip & tongue graft does not leave exposed edges, so is potentially healthier.  In theory, all exposed scion cambium is matched with rootstock or branchstock cambium.  That's if the cuts are skillfully done.

I found that sharpening the knife between each graft, the wood cut very steadily.  I steadied my hand against my chest and mad the cuts very slowly, slicing along the blade. The biggest  concern with this method is it is hazardous to the fingers of the grafter.  I did get a small thumb laceration.  It only needed a bandaid.

Whip and Tongue Graft on Asian Pear


I used polyethylene wrap and treekote.  Looks nice and they seem like strongly splinted grafts.

Photo is blurred but still better than my sketch.  I found I had overlap of cut edge over bark.  So I carefully exposed cambium by shaving that section of bark.  Then it matched.

They are a little bent.  They came together with the wrapping.  I dipped in water so cut surfaces would not be dry.

Labels state variety name, expected ripening time, and on the back, graft date.

Wrapped snugly with polyethylene, and labeled.
Some references state polyethlene wrapping does not need external sealer.  Other references state sealer is needed.  A key to success is prevention of dessication, so I sealed.  Treekote is easy to apply.  Messy and not easy to get off the fingers.

Altogether today I did 3 grafts on Hosui pear, 3 grafts on unknown Asian pear, and one each on 3 small apple trees.  Then I wanted to do more but I had homework and a doctor's appointment so I quit.

Lessons learned today.
1.  Grafting is not as hard as I thought.  It takes practice.
Sealed with Treekote
2.  A very sharp knife is essential.  I used a grafting knife, and a hunting knife sharpener from Fred Meyer.
3.  Apply bandaid to thumb before starting.
4.  Work slowly, carefully.  Don't try to slice quickly.
5.  The whip and tongue stays together nicely and does not leave exposed surfaces.
6. Prepare labels ahead of time, with variety name, date of graft, and expected ripening time.  Label each graft as it is completed.
7.  Polyethylene tape is easier than wide rubber bands.  It can be cut from freezer bags, although I got mine via Amazon.
8.  The Treekote is easy to apply too.  That was also via Amazon.

Maybe this weekend I'll graft some plums and cherries.  They are considered more difficult.  The grafting season is short, so I might as well do it now instead of waiting to see how the others do.

Grafting fruit trees. Progress Report.




Pear Graft #1
 All of the pear grafts and apple grafts took and grew this year.

I did not keep track of varieties.  The pear grafts were on the 2 Asian pear trees.  The intent is to have pollinating varieties, on the same tree.  And novelty.

The pollinating varieties were, two from a multigraft Asian pear in the Vancouver yard, plus 2 prunings from newly planted pear trees.  Those were European pears, Rescue and Orca.
Pear Graft #2

Pear Graft #3
 Some of the grafts grew very fast.  Others barely grew.

I grafted the apples on Feb 23rd at the Home Orchard Society grafting class.  Spitzenberg and Suttons Beauty.  Each has 2 strong growths.  Late winter, I want to graft each with an additional variety.  Or with 2 additional varieties, allowing a bud to form a branch below the graft for the originals.  These would be very low branching trees, which is what I want.  I want to get them planted in-ground this fall, so the roots have a chance to grow.  That means I will need deer protection, too, which is more of a chore.  Not too difficult.

The regenerated Honeycrisp broke off near the ground, but above the graft, last year.  I debated re-grafting it.  Instead, I pruned short, and allowed the tree to grow from below the cut.  It has 2 strong growths.  Again, I would like to graft an additional variety onto one or both of the growths.

In the Vancouver yard, I have the Honeycrisp start, Jonagold, Liberty, and Karmijn de Sonneville.  At Battleground, there are the columnar varieties Golden Sentinel and Red Sentinel.  GS had one apple this year.  It's only about 2 feet tall.  That's enough varieties for my test garden.

There is also Prairie Fire crabapple, now, which I hope serves as a pollinator.

Pear Grafts

After taking the Home Orchard Society grafting class, I was anxious to try. These are the attempts. This is a russeted Asian pear, Chojuro. I've grafted a nonrusseted variety, unsure cultivar. Purpose is for pollination. Mostly I think it's just cool. This is the nonrusseted Asian pear. Unknown variety, had one pear last year. Grafted another unknown onto it from my home tree, plus 2 Euro pears, Orcas Island and Rescue. I tried to graft near the trunk.  Not the best grafts I've seen.  We did bench grafting in the class.  Learned whip and tongue graft, which took more finesse than I have on the bench.  On the tree it would likely have meant a blood sacrifice to the tree god.  So I tried the less hazardous but possibly less successful cleft grafting.  No loss if they don't take.  Pears have a reputation for easy grafting, so maybe.
