To prep a scion you remove its leaves and leave it on the tree until its buds start to swell, so you know it's full of energy and ready to push. My scion was from a HUGE seedling sap with spectacular fruit we want to propagate. Especially because the tree is so large, it took several weeks for even the slightest movement of the buds. I cut it as soon as the tip bud started to green up a little.
I'm NOT an expert grafter. I had a miserable take rate of about 50% with avocado and citrus (the easiest to graft) and 0% with mango. I got my 50% with clefts and modified clefts - I don't think I ever did a successful veneer graft. My luck changed when I started doing a version of the "gravedigger" graft (search the forum for gravedigger and you'll find the thread), which I would say is a modified bark graft. Suddenly my citrus and avocado percentage shot up to over 90% and I have similar results with mango. I cut off the branch where I want to graft, peel down the bark as for the gravedigger method (usually I leave a flap but it's not necessary) and cut the scion with a long cut on one side and a short wedge cut to a point on the other. I don't have buddytape or parafilm so I use regular plastic wrap which I like because I can pull it very tight for good contact, but I have to be careful to remove it after the graft takes or it will girdle. I'm mostly topworking established trees/seedlings and this method has been virtually fail-proof doing that. Rootstocks in bags are harder to graft because they just don't have the vigor of planted out trees with good root systems, so my luck with those has been considerably less but still better than I had with other techniques. The only caveat with this method is the rootstock needs to be bigger than the scion so the flat cut of the scion has a flat surface to adhere to, otherwise you can only get contact on one edge and it's much less likely to take. If you're topworking or working on established seedlings it's easy to have rootstocks thick enough for most scions, but that can be a problem for rootstocks in bags. If you can, I recommend planting out rootstocks and letting them settle in for a year before grafting. Grafts are more likely to be successful and they take off like rockets on established trees.
As for the latex, I pretty much just ignored it but I do think the first attempt might have failed because I went too slow and maybe the latex started to dry up a bit. The second time I worked more quickly. I also did one with a non-prepped scion that looked it had a swelling tip and it hasn't started to push yet but it's still green. Like I said, you're going to wait either way.
Hope that was somehow helpful! :)

For anyone interested I got my second sapodilla graft (first failed) to push in under 2 weeks having prepped the scion. Of course, I had to wait quite a while for the scion to be ready, so yes you're going to wait one way or the other, either before or after grafting. I prefer to do the waiting before the graft, though, so I can know fairly quickly if it takes or not.

Iíve emailed him several times and gotten no response. With th COVID numbers like they are in FL I canít help but worry. Is anyone here in touch with George?

Another question for you sapodilla grafters: do you prepare scions like we do for mango and avocado? Or what do you do to get ready to graft/select bud wood?

5
I have 4 ginormous sapodilla trees on my property. Two give pumpkin shaped fruit with dark flesh, sometimes slightly grainy (not at all offensive), intensely sweet and richly flavored. I couldn't pin down what the flavor was exactly until the other day when it just hit me - root beer! It tastes like the best root beer ever! Has anyone else ever detected root beer flavor in a sapodilla or is it just me (or just my sapodillas)?

See this method that is shown in this video.

https://www.youtube.com/watch?v=HKTcBEjGKkE

It is not exactly cleft nor is it veneer.  I believe she has it demonstrated in another video on grafting.
I use all depending on the material I have.  There is a veneer method method that Zill demonstrated here https://www.youtube.com/watch?v=fp_QOOLRTcI and a variant of sorts that a forum member coined "grave and coffin" strange name but decent method for some types of scions.

My suggestion practice them all.  If you prune your plants, practice your cuts and on the branches you plan to prune before or after you prune them. 

Enjoy

Just chiming in here because you're new to grafting. I had some success with avocado and citrus but zero with mango until I tried the method mentioned above. I have almost 100% with this one when working on in-ground trees. I won't even bother with any other method. Only thing is the root stock has to be somewhat bigger than the scion. I highly recommend it.

Thanks everyone thatís great information. Yes weíre cutting back the tree to the main trunk trying to make the tree more manageable, and Iíll graft the sprouts when they get woody but are still green. Thatís worked great for me with citrus, mango and avocado but Iím still worried about the latex with sapodilla - hard to believe it wonít interfere with the union.

Aha water rinsing! Do you pat dry after rinsing or just leave it wet to graft?

9
And my last bump. Apparently no one topworks saps?

10
Bump. Anyone?

Hi all. We have 4 giant seedling sapodilla trees on our property all of which produce lots of excellent fruit. But Iím curious to try a cultivated variety and had the opportunity to bring down a small Molix. One of our trees is especially tall and produces less than the others with most of the fruit too high to reach, so we decided it was a good candidate to cut back and graft at least a few branches with the Molix. Iíve done this successfully with citrus, mango and avocado but have never tried grafting sapodilla. Has anyone done this? How do you deal with the lŠtex? Any suggestions? Thanks in advance for your input.

Tropical Fruit Discussion / Re: Relative flowering times for avocados?
« on: March 12, 2020, 01:05:54 PM »
Hmm. In general I've noticed with mango that our seasons seem to be about 3 months earlier than yours there, and that would be consistent with our Choquette flowering starting in December and Alex saying Choquette there starts now. Our Pollock is just starting now but that could be because it's a top work graft that's just a year old so it might be off its regular schedule. I also have a top worked Oro Negro bigger than the Pollock and a grafted Oro Negro in the ground 2 years that aren't showing any signs of flowering, which seems weird. Our Catalina planted the same time as the ON has a mixed bloom. The Kampong I have is a top work and shows no sign of flowering yet. Our only super established tree is the Choquette which is enormous, so it may be the only one on a regular schedule.
I wonder how much elevation affects season?

Thanks for the replies! I need relative flowering times, though. When do Choquette and Pollack flower for you guys?

Now's a great time James.  I did a lot of grafts in the last 2 weeks and have severalushing now.
I've never tried a t bud but I have chip budded avocado successfully.

I'm in Venezuela. I was asking about relative flowering times because no one else here has Kampong or Oro Negro.

Hi all,
Can anyone tell me if I've had Choquette flowering since December and still in full bloom,  and Pollack just starting now, when might I expect flowers on Oro Negro and Kampong? Thanks!

Tropical Fruit Discussion / How to prune/train/trellis Mysore raspberry
« on: December 18, 2019, 07:20:36 AM »
Hi everyone,
I know most people here disdain the Mysore but I find the shade-ripened fruit to be delicious, plus it's perfect as an impenetrable barrier for security purposes, with fruit as a bonus! Our original planting, however, is not in a location where we want it going wild so we need to tame it somehow. I just don't know where I'm supposed to cut in order to maximize fruit production and minimize its sprawling. Can anyone help or direct me to a guide or something? Much appreciated.

Tropical Fruit Buy, Sell & Trade / WTB Dream annona small plant or seeds
« on: November 27, 2019, 10:24:49 AM »
Can anyone direct me to a source for a small grafted Dream plant or at least seeds that will ship to Miami FL? Thanks!

23
Yes. As long as they are ripe when picked or when they drop, they will continue to ripen and sweeten up some, and lose acidity and sourness.  Wrinkled ones are fine with me, they are just near the end of their goodness.

An unripe passion fruit picked early or that drops early will not ripen properly.

Thank you very helpful :).

Sometimes fruit drops from our vine pretty green - will it sweeten up at all on the counter or not? Thanks!
