So, have we established a gold standard protocol on what to do to keep the trees alive? I see the pictures look like they have grafting tape wrapped around the trunk. Did they come like that or is that moisture preservation technique?

Here is my updated list 2.0

2x Biqi Female
1x DongKui Male (Changed per your suggestion to  dadloring)
2x Dongkui Female
2x Crystal Female
2x Late Growing Female
2x An Hai Female
2x Black Diamond female
2x WuSu Female

Have we settled on the fact that Black Diamond is a unique cultivar and is not another name for Biqi? If yes here is my updated list.

2x Biqi Female
1x Biqi Male
2x Dongkui Female
2x Crystal Female
2x Late Growing Female
2x An Hai Female
2x Black Diamond female
Thank you for your patience Bill.

Bill, please add 2 An Hai to my order. Here is my updated list:
2x Biqi Female
1   Biqi Male
2x Dongkui Female
2x Crystal Female
2x Late Growing Female
2 An Hai Female

Hey elouicious,

I actually now use a customized fertilizer that I developed for rapid growth. If you use Osmocote slow release, I would use 1/2-1/4 of what they recommend. I previously use Dynagro liquid fertilizer.

I don’t think these trees will do much growing in Winter but I expect them to grow rapidly in Summer.

My soil is a horrible heavy clay with lots of rocks and poor drainage, that is why I plan on planting most my test trees at my parents and in laws. My backyard has better soil so I believe it will grow fine back there.

Ok,
So what's in the secret sauce? You know we want the recipe

How long did it take to flower? If you have a guaranteed male. Would you be willing to sell some scions?

There seems to be no casualties in the unheated greenhouse...yet. I haven't been out there to check. Day time temps are in the 40's now with nights around 25. My heating method is to heat up a 50 gal trash can with hot water. It seems to raise the temp of the greenhouse about 5 degrees. So 30's with 100% humidity.

I am hunting these trees but they seem to be rare in the trade in the US. It seems like they pop up then go away. It's not something that is constantly available like guavas or "you name it". It seems like grumichama is getting "rare". I used to see them at nurseries all the time. Anyway. Whoever knows who's selling them ( I mean a reputable grower or nursery) let me know.

BTW
What's the possibility of importing from Australia? How would I go about doing that? I mean like ordering 200.

I did am experiment. I covered a Bumper, Orange frost and Arctic frost with black trashcans during the last 5 days of Alternate snow and wintery mix in zone 7a/b. I also added a 5 call bucket of water. My theory was that on the snowy cloudy days they would be protected from the cold winds and they would have a higher temp on the sunny days than the projected outdoor temp. The controls were a ponkan in a 7 gal pot, and kishu in a 7 gal pot (both next to a cinderblock wall),an in ground ponkan and in ground trifoliate. The temps in Fahrenheit were :
Date       16        17        18        19        20        21        22
Temp 30° | 19°   36° | 27°   42° | 25°   51° | 28°   46° | 30°   31° | 21°   34° | 16°

The trifoliate did the worst with significant leaf curl. All other plants had no leaf curls. The uncovered plants had some yellowing (ie they were less green ).

Bumping this old thread up!

I have fruited my seedling from Marcos this past year. It was delicious and I had the same impression as Marcos in that it was sweet and had an apricot-y flavor, less tannins and "tartness" that you might find with the classic E. involucrata. 

I have no idea what to think of it's classification but it does morphologically represent E. involucrata minus the fruit color itself, which as far as I know, isn't usually criteria for being a different species. 

sell us some seeds

Ditto!

Carolinazone, I just cut some of my Supersweet branches today, if you want to buy some I can sell it for $4 each plus $9 shipping.
Also have the Younghan's Gold and Bonita Springs. Send me a PM if you're interested in the cuttings this week.

How do you like Younghan's Gold?  I'm thinking I should go with that one.

I am curious too. I have had conflicting information about Younghan's vs Young Hands, vs Younghan's Gold. Some say they are the same some say they are different.  Just to confirm what do you think about grafting in low temps? All my stuff is in the unheated greenhouse and I running about 33 degrees F average.

A friend of mine successfully grafted black sapote on a native persimmon this past summer.  Native persimmons routinely pop up along the banks of a small pond on his property, of which he typically grafts superior Asian persimmon cultivars.  Also, his property experiences seasonal flooding which doesn't appear to affect any of the trees.  I'll find out if the seasonal flooding ever causes fruit drop, since harvest sometimes coincides with fruit ripening/harvest.

Really? I thought they were graft incompatible. I have Asian, American, Texas, and black sapote. Sring might be the time for me to make a Frankenstein multi-graft experiment. What about ylang-ylang. Is it also graft compatible?
OOps. Ylang Ylang is in the pawpaw/custard apple family.
