I have a cherilata I grafted onto soursop if you want, recently potted up into 3gal if you want it for 45$ let me know, live in palm city. I can send a picture of it tomorrow in daylight, cleft grafted beautifully to soursop. I drove 6hrs round trip to Fruitscapes where I bought a 7gallon grafted to pond apple, the cherilata to pond apple does NOT make a good graft union based on the options I had to chose from when I purchased...so I grafted a few onto soursop with great results and have a soursop grafted cherilata planted out in my yard.
