The Campbell white sapote from Julian is fairly priced at $45 plus shipping. I have purchased 2 plants, one last year and second one on 3/6/24. The grafted tree is old enough to ship, looks to me the graft is maybe 9 months to 1 year old. The graft union is healed so there is nothing wrong with the trees he is selling and shipping out.
Maybe this variety could be a slow grower or depending on the seedling rootstock it grows a little slower than other white sapotes. I germinate a lot of seedling white sapotes plants and they don't grow much the first year, by the second year it will be much better size.
Here's the photos I said I would take of my two plants purchased from Lara farms.
