Grafting Fruit Trees, Interstems, Compatibility between Cherry, Plum, Peach, Apricot, Apple-Quince

[@ceciliashevlin1152]

Extremely interesting video! Thank you for sharing your experiments!

The apricot I bought from a large tree nursery here in central Europe came on a plum rootstock (St. Julian A). It has grown very well so far for around five years.

[@Veritas-dn6ss]

Here are a few more that work: Sweet cherry to Amur Cherry (Amur is zone 3), pear to Smoky Saskatoon (you get several years of production until the Saskatoon dies, graft at chest height only), pear to cotoneaster (a long term union and a dwarfing pear tree that only grows to about 8 ft. max, you need to have 2-5 cotoneaster branches under the pear graft to feed the roots), pear to apple M26 rootstock, pear to Winter Banana apple as an interstem on an apple tree. Pear and shipova on Mountain Ash always take well for me, but always die after one or two winters (but I'm in zone 3 with harsh winters).

[@nickkasko2097]

Shipova is going strong on mountain ash for roughly 8 years or so

Thanks for sharing this valuable video and all the information. It is the most beautiful video, full of experiments and practical knowledge. I have subscribed too.

[@ParadiseGardens]

This is so fascinating! I've been gardening for decades but this is my first time grafting. Thanks for sharing this valuable information ☺️

[@michaldurana4227]

Is seems to be interesting and maybe useful to try on plum rootstock graft a pluot , on pluot plumcot, on plumcot an aprium and on aprium apricot :) ... Black apricot is an aprium I think and so it has better compatibility with apricot than with plum.. what do you think?

[@NasierOmran]

Whats your experience with crafting plum to cherry tree..? Or Mulberry on Fig?

[@nickkasko2097]

Have grafted Plum to cherry grafts that survived for one year, and then died. Still need Z-stem to bridge plum and cherry. There’s no other way to get around the incompatibility

Great video, you’ve put in a lot of years work there, well done

Thank you from Sacramento, CA. I have plums from the original home owner, several types. The original plum trees grow like weeds. They are not Marianna. I bought Marianna rootstock and growing them in pots.Matianna is not as dark red bark colored than the original which also are very hard. Those do not grow fruit or only a a few as in one or two if ever. I want to use an interstem between the original rootstock that grow all over the yard. If I don't cut them out every year, they grow fast, both tall and thick vs rootstock in dwarf trees I have planted in the ground. Nemaguard rootstock works very well in my Flavor Aprium. Not sure if I can use Nemaguard as an interstem or if I can use Marianna.

[@ceciliashevlin1152]

I’m just n Sacramento also, very interesting in learning to graft!

[@cowboy399]

I have also experimented with ornamental hawthorn. The advantage there is it doesn’t have thorns.

Can u graft a pear stem to a nectarine tree??

Hi Nick, excellent video thank you for your knowledge and keep up the great experimental work. Greetings from Melbourne Australia Harry

Great stuff, Nick.

Fascinating stuff

[@michaldurana4227]

Nick, thanks a lot for this great video. This is my most favorit topic. Please, can you write here the name of a hybrid between apple and quince (Sidolius???), and the name of the next hybrid species in 37:00 (upro 6???) I didn't catch that. Thank you very much. Here in Slovakia I am trying to graft on wild hawthorns (they grow here everywhere) pears and apples. Pears are doing better on hawthorn than apples, so this hybrids you shown can be for me here the solution to make a bridge between hawthorn and apple.

[@MrKellso]

I did not catch that name, either.

[@donc7349]

It is 'Cydolus'

Do you happen to know if you could plant a plum tree into a cherry stump? I have an Italian plum in a pot right now, but it's about time to put it in the ground. The best spot for it just happens to be where a giant Japanese cherry used to be before it was cut down. The stump is fairly large, and I'm wondering if I can "plant" the plum inside the stump if I hollow it out.

[@nickkasko2097]

I don’t see a problem with planting it in the stump if the center has rotted out. As long as the plum roots will be in the soil is all that matters

[@cowboy399]

Have you ever experimented with grafting apple and pear to photinia? It seems to take and has lasted more than 1 year so far. Loquat can also be grafted to photinia and is done commercially in China.

[@nickkasko2097]

Never tried it

[@goodmusic3679]

Thanks for this interesting video. I am planning to graft peach and plum on Nanking cherry as a dwarfing rootstock. I also have some seedling mountain ash to try with shipova, as you have done. It looks like you have had success using whip/tongue grafts with prunus - it seems most people prefer budding with stone fruits but I will be doing whip/tongue to see results the same season. I’d be interested in knowing if you have ever grafted both parts of an interstem at the same time, or if you typically graft the interstock the season before adding the desired top variety. Thanks for the great content.

[@nickkasko2097]

I have done both but with stone fruit, the top graft has a high mortality rate if grafted at the same time, two story graft. With apple and pear, you can get away with it with minimal issues.

[@alfredopampanga9356]

Off topic. What is the plastic sheeting doing? Solarisation?

[@nickkasko2097]

That’s weed plastic to kill the weeds. Will remove in a few years after weeds have been eradicated

[@cowboy399]

I wonder if you could use a bridge graft using an interstem on a graft that didn’t take well - kind of like you do when a tree is girdled?

[@nickkasko2097]

Probably could, I don’t know if I would be worth it tho. You would end up with two trunks with bark trapped inside.

[@cowboy399]

@@nickkasko2097 I guess it depends on how much you like the tree … with a tree that was eaten by mice they usually graft all the way around. In this case you could have 4 grafts for instance equally spaced around the trunk. I read a very old book on grafting where they make vertical cuts across the graft union when it shows signs of rejection in order to stimulate growth and healing there. I wonder if that really works?

[@cowboy399]

Somebody gave me some tiny adara scions last summer. I have two grafted to ornamental purple leaf plum and 3 grafted to European plum. They are too small to do anything with but they are all alive and doing well. When they get big enough i can use then as a source for other scions. I read a paper that claimed some purple leaf plum varieties can be used to graft cherry to but i didn’t have any success with that.

Can you graft Romeo and Juliet to mahaleb

[@michaldurana4227]

Nick, please where can one's get the упроз 6? Thank you very much

[@nickkasko2097]

If you are in USA, I’ll have it in about 2 years to sell as scion wood. It’s bred in Ukraine, so you can possibly get it from Ukraine if you are in Europe. It’s new so you may not be able to find it. And I don’t ship outside of USA.

@@nickkasko2097 thank you , I didn't find much information about it. And what kind of hybrid it is please?

[@nickkasko2097]

@@michaldurana4227 it’s also an apple quince hybrid

[@michaldurana4227]

@@nickkasko2097 thank you, so it could have similar compatibility to all of the trees you mention by упроз 6 as the Cydolus? Something like adara and Z stem?

[@nickkasko2097]

@@michaldurana4227 I would customize my unions by using cydolus specifically for quince and apple connections even tho it probably has wider compatibility, would need to be tested. Упроз 6 is already tested to be compatible with quince, apple, pear, mountain ash, hawthorn, medlar, cotoneaster
