Grafted Myrciaria dubia (Camu camu) on M. vexator (Blue Jaboticaba) Rootstock

http://tropicalfruitforum.com/index.php?topic=11876.msg152528#msg152528

We discussed this plant a bit earlier, in the how to graft Jaboticaba (Myrciaria/Plinia) thread, which I posted above.

here is an updated picture of the tree, (M. dubia, grafted onto M. vexator, appox 2yr ago)







I believe this plant (graft combination) represents an opportunity for growers in South, FL, where the climate is good for growing Camu camu, but the soil is horrible (lime rock, with high pH), making it almost impossible to grow this species, without digging a big hole, and replacing the native soil with acid sand, or peat moss, and also drenching with chelated Fe.

The rootstock I've chose to employ, is the Blue jaboticaba (M. vexator).  It can thrive in the native soils of South FL, as long as it's fertilized, and properly irrigated.  In theory, this resistance for high pH (lime rock soil), should be imparted into the grafted tree, making the scion (M. dubia) more capable of surviving the adverse conditions of South FL soil.  Although the trees will be more resistant to high pH, I'm sure they will still require periodic drenches with chelated Fe, until they are established...but the amount of product required to keep the plants thriving would be a fraction of what you'd have to use if you tried to keep M. dubia alive on it's own roots.

It would make me really happy to see a grove of Camu camu fruiting in the Redlands of FL (even if it's a very small grove, or just one tree! haha!)

This rules! Thanks for the info Adam. Trailblazin.

Another grafting success, Adam. Way to go.

haha that's awesome. Is camu camu any good?

You should actually be able to modify the pH of your soil really easily with sulfur. I imported 250 cubic yards of loamy sand from palm beach county (roughly a quarter acre to a depth of 1 foot) and was able to drop the pH from 7.4 to 2.4 in the span of about 8 months with sulfur. (My intention wasn't to drop the pH that low. Apparently I underestimated the amount of calcium carbonate in the sand :-).

That "variegated" (aka heavily chlorotic) starfruit is now dark green after dumping 10 - 15 pounds of sulfur around it about 18 months ago.

It's magic. I'm not sure why folks here don't use it much. Pelletized sulfur once every few years is way easier than dealing with chelates. Har was the one who turned me on to sulfur.

If you're on marl (ie, if you live in dade county), sulfur does no good. But, it works extremely well on sand.

CM: good to know. I have sandy soil so sulfur may be an option when i get some extra dough.

Adam: now we are talking. Not only is that another sour/medicinal, but you also found a use for blue jabo

It's actually pretty cheap. Helena Chemical in palm beach county has the sulfur for about $18 / 50 pound bag. You might only need a couple of bags to do your lot.

Adam,

Have you tried using Humic acid with Myrciaria dubia?.

[FlyingFoxFruits]

Adam,

Have you tried using Humic acid with Myrciaria dubia?.

yes, for sure, I use a product called Agri-pro (Turfpro)

it definitely helps, but it's not enough.

I've had great results with chelated Fe...

it's been my saving grace, with many of the rare Brazilian species.

[FlyingFoxFruits]

updated pics...seems like they might be a good match. 

the tree is growing faster now that it's older.

I always get a kick out of reading these abstracts...

They should have been trying interspecific grafts...not intergeneric.

I'm surprised they didn't have the common sense to realize this

Nice grafts! I was also thinking the same thing about the interspecific grafts lol.

Adam, hey, this is Alan from SoCal.  I was just wondering, what database do you check for searching journal articles--Google Scholar,  or some other journal database like Web of Science?  I agree, that is a very strange goal for a research journal article.  They did a lot of work for the research, and they got results that should have been expected.

hey Alan,

I just did a google search for the term "grafted Camu camu"

I don't understand your point.
The paper describes grafting camu-camu onto psidium and eugenia. Aren't these species in different genera
in regards to camu-camu?

[FlyingFoxFruits]

the differences between genera are too vast, they should have been trying to find a compatible species within the genus Myrciaria.

Sorry. I thought you were complaining about the term used, rather than the choice of species.

Yeah, but loquat on quince says otherwise ;-)

[FlyingFoxFruits]

Maybe true for quince and loquat...but that's comparing apples to oranges! 

They should have known better...they have college degrees!

they graft up real nice...getting high success rates.

Nice! I've got some questions to ask you. 1. How long has it been since you first grafted this one? 2. Is there a particular season required to graft Myrciarias? 3. Will you make more YouTube videos sometime? Your videos are Awesome!

thank you!
first camu camu i grafted was in 2014, that one is doing very well, almost 6ft tall now.

but this tree in the photo was grafted about 35 day ago it seems?

for me, the best time to graft Myrciaria/Plinia is during transitional phases, like summer to fall, fall to winter, winter to spring.  Heat of summer and cold of winter can be problematic.

not sure when the next video will come out!  could be years!
