The tops to both my innarched seedlings are starting to push new growth. They were actually already pushing before i innarched and I purposely waited until I saw active growth before grafting but the good news is that the branches continued to push new growth that hasnít dried up yet. In the innarching process, I cut 1/3 to 1/2 the diameter of the branch off before joining and binding the branches and sometimes the injury causes new growth to dry up. Itís still way too early and Iím still skeptical about the success of these grafts but at least things are looking good so far.

The parafilm on the innarch graft is starting to crack along the Union so I know the callous must be forming and healing over. I decided to cut a notch above the graft on the seedling and also cut another notch below the graft on the Emperor in order to divert energy away from my future cuts. You can see the lighter color notches directly above and below the grafting tape.

Simon,

I am new to the Lychee growing so this might be a question that has been asked.
Are the Florida Lychee trees ok to grow out here in So. cal or is it better to purchase a California grown Lychee.

Hey Lionking,

The Lychee trees from Florida grow perfectly fine here. Mauritius, Brewster, Sweetheart and Hak Ip do well here but Emperor can have issues growing in our high pH soils and high pH city water.

Iím going to see if I get better growth of Lychees when they are innarched onto seedling rootstocks.

Thanks Simon,

Looking forward to reading your results on your experiment..... good luck!

I am performing in Israel, a lychee longan grafting experiment with all varieties I can find here.

A commercial nursery performed a smaller experiment and the success rate, as told me was 50% in such grafts.

An old US report from 1948 clearly specified that both lychee and longans have special anatomy that limits types of grafts.

Propagation of lychees by cuttings is easily done with 88% pf success as told me by one nursery. Others propagate by airlayers.

There were 300 hectares of lychees in Israel and 200 were pulled out by angry growers

It seems that micorhyza is important in various high pH soils here, and the heat and other drying conditions kill it.

Will be happy to show results next year and keep in touch here.

Ariel, a couple members here have successfully grafted Lychee onto Longan rootstock, see this link:

Hereís a quick update on my Emperor Lychee innarched onto seedling rootstocks. Notice that I already notched the Emperor and the seedling. I then snapped the branches. Iím about ready to completely sever the connections.

I finally did it and severed the final connection. Hopefully they can take this heat wave. Iím putting them in partial sun for the next couple weeks to get them acclimated to full sun. You can see that the union has healed up very cleanly.

Nice job Simon.  Glad to see and read that everything is going well.
And thanks for the info on Florida Lychee trees.
I purchased a Brewster from Palms and More in Fort Lauderdale.  So far the tree is doing great.  It did get a little shipping and transplant from pot to ground shock but i am now  Starting to see new growth.

Thanks Lionking,

Hereís what the union looks like with the tape completely removed

The unions healed up nicely.
Please keep us updated as time goes bye. 
Your experiment success will be helping a lot of us with the way we grow lychee trees.

Looks good Simon, I think I'll try some of the varieties I have and put them on the seedlings I have.

Also, I was a Quail gardens today and someone is air layering  a couple of lychees. One is labeled as "Kwai Mi", have you ever heard of that one?

Probably the same as Kwai Mai Pink (often with the misnomer, Bosworth #3).  In low chill conditions can be more productive, usually every year, than several other varieties.  Low to medium vigor.  I only observed one tree, between a shell-rock road and a shade-house--- so it got water every night on the shade-house side, and it got lots of Calcium, and drier conditions, on the road-side.

Hey Mark, I agree with Har but Iím a little confused as well because Iíve heard Kwai Mai Pink being called Bosworth 3. Iíve also heard regular Kwai Mai being called Mauritius. Kwai Mai literally translates into Cinnamon flavor in Cantonese.

The Kwai Mai Pink is a smaller fruit that is sweet and the fruit can get some fungus on it that resembles Anthracnose, maybe it is, but is still highly productive. The Fruit has a weak Lychee/Rose flavor but I still like the fruit because of the lack of acidity.

It may be worth it to try to make sure the tree is not Mauritius before trying to acquire plant material.

Mark, with your huge Lychee tree, I would try to acquire scions from all the top varieties and multigraft your tree assuming air layers of these varieties are not available. Once the grafts take, you can air layer the different varieties.

Quick update of my Emperor Lychee innarched onto seedling rootstock. It is pushing a nice small flush. The tree is in a very small tall pot and I need to up pot it but Iím going to wait till the flush hardens first.
