There should be no problem. This would be a standard graft.

What flowering cherry do you have?
It wouldn't work on all prunus,...Prunus virginiana is not compatible. Prunus pensylvanica yes, I found they're not all the same in the wild,...some are not compatible.

I know sweet cherry and sour cherry are not compatible when grafting.

I had fruiting Stella & Lapins on Sour cherries.

This is Stella on Evans,..tree has died.

Lapins on pin cherry,... graft froze back.

"I know sweet cherry and sour cherry are not compatible when grafting."

Pacific Groves is a wholesaler that grafts sweet/sours on same tree. Doubt they would this is they weren't compatible....

Oh, also if you graft fruiting cherry onto an ornamental cherry, you will likely still need another pollinator if you want to get any fruit, because the Kwanzan cultivar is sterile (24 chromosomes), and Yoshino is a very bad pollinator (these are by far the two most common varieties of ornamental cherry sold in America).

One more tidbit of information to add: Sweet cherry can be grafted onto sour cherry but the two are generally not considered graft compatible. However, this might only be because sweet cherry grows at a significantly faster rate than sour cherry (sour cherries are naturally kind of dwarfed). Sweet cherry and flowering cherry, on the other hand, share a very similar growth tendency (and both can get to become quite large when not grafted).

You may be able to get fruit on sweet cherry grafted onto sour cherry rootstock but the tree will not show good performance, may likely have a high rate of graft failure later on.

I am an novice ’grower/landscape’ guy; and for ’fruit production’ sake and home-gardener ’space’ limitations…let me ’tell’ my experience

I live in San Diego and desired to eat sweet cherries. So i grafted twig-sized Lapin cherry tree onto Kwansan flowering tree…in the Spring that flowering-cherry set Lapin fruit and grew and ripened. Just FYI!😊

Oh….I also was sucessful grafting Lapin fruiting cherry twigs unto Yoshino flowering cherry and produced fruit in the Spring. San Diego climate doesnt have enough ’chill hours’ to produce Bing cherries, but Lapin variety is the same size and just as sweet and tastier requiring 450+ chill hours. Again…just FYI

Lapins (note's' on end and not for the plural :-)) are also self-fertile so will fruit on any cherry you can develop a compatible graft with.

The ’variety’ is called Lapin (..a Canadian variety) and i cant remember if the word is singular or plural. But the variety is self fertile.

Experiment…’try’ this ’fruiting’ cherry tree with flowering cherry tree. I was pleasantly ’shock’ to see this experiment actually ’fruit’…

As I attempted to point out, the cultivar name is LapinS, with an "S" at the end. It is neither singular nor plural......that is just the correct name. This cherry was named for the developer, Dr. Charles Lapins of the Summerland Research Center, British Columbia.

I also pointed out this cultivar was self fertile and should produce fruit with ANY successful graft.

Hi Joelisrael, pardon me for asking. May I know the type of graft you employed, please? Thank you. Kind regards JonathanNZ

Hello Jonathan, i use to buy ornamental flowering cherry trees. I live in San Diego and there isnt enough chill hours for sweet cherries (now there is…Lapins)…so i experimented by grafting Bing, Lapins, and Stella ’twig-branches’ by ’notching’ and whip graft and splitting one branch into another. They all fruited but the Kwansan flowering didnt survive passed 2 years because of my neglect. Is that helpful?

Thanks Joel for your prompt response. I am from Christchurch, New Zeakand. I am planning to head off my flowering willow cherry as shown in the picture and graft the Stella onto the main trunk instead of the branches

. What do you think of the surving rate or is there any suggestion or advice ? Your kind advice is very much appreciated. Thank you. Regards, Jonathan

Well Jonathan, first i would ’thin’ and clean up the branches, as you ’intend’ …first. And while the tree is ’dormant’ I would try about a dozen or so…’fruiting’ cuttings by ’whip’ grafts, and those other means that i tried to describe. I suggest you go on YOUTUBE and ’see’ how grafting is done. Now, I’m not sure that what I did ’should have worked’ because im not a GROWER nor scientist…I just wanted to try…and to my shock it worked for me! Please let me know if you are successful.😊

The climate in New Zealand…would it be like Zone 8-10 or do you get ’cold’ weather in your Winters? I live in southern California and as you know, we dont get much ’rain’ let alone temperatures below 50* almost all year long. i visited Campbell Town Scotland once and that temperture remained cool and damp most of the year…(I was informed)…and though i always wanted to ’see’ Australia and New Zealand, i never got an invite so i don’t know the climate. a great encouragement to guys like us is to watch videos on Youtube about growing Food Forests!!!!…and those guys amazing success about all types of ideas!!!!!

Thanks again Joel for your kind suggestions and advice. I will definitely give it a go as you suggested and will keep you update of the outcomes. I am Keeping my fingers crossed 🤞and hoping for the best🙏. Well, the weather for this winter has been quite cold in Christchurch but no snow even though it has dipped below -2C. If you ever has an opportunity to visit the down under, please come to the south island …you would be experiencing way more than you expected! Cheers 😘

Okay. And thank you for the invitation to New Zealand…if the ’world’ were ’different’ than it is now, I would definitely plan a visit!!!… I love travel and miss it! Keep in touch and tell if successful or otherwise😊
