I am not an expert by any means on Jaboticaba, I have be-en growing them for close to 40 years. This is what I have learned to work for me, I have grown them in a perlite - 40%, Canadian peat- 40%, coarse sand -20%, straight 1/4" lava, Pro Mix, Canadian peat/ perlite with mycrrohazae, and a custom inorganic mix. I use an 18-5-10 time release 360 day release with micros, in addition I use another fertilizer caled Micro Max to correct yellowing, it is rather expensive $110 for a 50 lb bag. About 20 years ago I rescued a ancient hollow trunk for a home being bulldozed training it as a bunjin, by supplimenting it with the same 0-56-0 Super Phosphate that I fed my giant Jab yard tree it stimulated the bunjin to blossom and produce fruit. I harvested 27 gallons of fruit from the yard tree, made excellent red wine using the skins and champange yeast. On my older established pre-bonsai I like to set them in terrcotta saucers level and half full of lava so the bottom of the nursery containers sit barely in water, they like to be a bit damp. I have found that leaf tips are party browned by the hot dry hard summer winds here in Palm Beach County, during this time of year I move them to partial shade in a protected area . When my good friend Allen Carver who took over his Grandfather's Jupiter Bonsai Nursery decided to sell the 10 acre nursery he sold off as much stock as he could and had to clear all nursery related items before putting the property under contract, he asked me to take as mush of the stock on the ground as I wanted as he was paying by the cubic yard to have it hauled at $750 per 40 cu yds, I removed about ten dozen Jabs in 3g, 7g and a few 15gs, all had grown thru the ground cloth into the native soil, very few hair roots in the pots containing 20 year old pudding soil, we mostly barerooted them and repotted into straight 1/4" lava, some ProMix, close to 100 Jabs didnt make the next year, some of the ones that made the next Spring are masterpieces in training.I have tried every way possible to airlayer, with powder hormone with Dip-N-Grow, with both- zero success. I did hear that partial success can be had by taking 2" to 4" tip cuttings with hormone under mist 8 seconds once every 10 minutes in full sun,
