Hey Peter,
OK, thanks. I have talked to Gary Zill's, quite out of my budget for his grafted trees, I think I just need to stick with seeds and then maybe graft as needed. I can graft the black sapote if I need to, just need to get the seeds-seedlings going for root stock then make a trip south to get branches from quality trees in 6 months if grafting is recommended for that tree. I might need to take you up on buying the red Jakfruit seeds from you if you can put them in the mail that may be my best option.
Avocados do very well here and I have quite a few trees but they aren't mixed in with my Cacao. I figured they were too heavy shade, so my mangoes and avocados are in their own area. For my cacao, I have my permanent trees Guama, guanabana, and Cashew inter planted between every 4th Cacao vertical and horizontal for one hectare, and I think the Guama have done the best for me due to its height, quick growth and reaching branches (still waiting on fruit, maybe 2020). Many of my Cashew trees have blown over and block out nearly all the sun which those cacao aren't too happy about, so looking for something else for those areas and others where I still need some cacao upper shade.
I am growing 5 sapodilla trees in their own area where I wanted a lot of shade for my dogs and have been quite slow growing for me here. I'm expecting 100% shade from them, so I don't think I would do those intermixed between the Cacao. I would consider the canistel. I haven't had canistel, but it looks like something I would like to grow and eat (have seeds?). My mamey sapote have grown very slow as I had them in too much shade the past 4 years, so I dug them up and moved them (only 4' tall) and hope they do better in full sun. Do the Canistel grow any faster than Mamey and Chico sapote, or do all the sapote family have about the same slow growth?
I've even considered doing some large Guapinol trees for upper shade with the cacao as the neighbors have said they are wind resistant and always have leaves during the dry season.
