My three would be a fig, a Euro pear, a persimmon, a peach, and an apricot tree. (Hey, I never said I could count!) I’m still working out which specific cultivars do best in my microclimate, though. @amh0001, are you coastal or inland?
The peach might be a good, old-fashioned Babcock, partly because they are sweet, low chill, low acid, and delicious, and partly because they are so perfectly round and beautiful hanging on the tree. An aesthetic experience all around. I grafted a babcock scion onto my big seedling peach tree in 2015, and by 2016 I had a branch with SIXTEEN gorgeous perfect peaches. It seemed unreal compared to the scruffy pickings I got from other grafts. (But note that I do spray with copper sulfate for peach leaf curl, or I couldn’t do the Babcocks.)
The pear I’m still working out which do best here, since we get a lot of black spot/scab and fireblight. My huge old Winter Nelis that was here when we moved in needs way more chill than we get here, so I’ve grafted much of it over to other types. Only about a third of them have fruited yet.
The fig is also a puzzle. My 3 year old Desert King does well here, but I find it bland. Maybe it will get better tasting when it’s older or if I step up the fertilizer. I’d love to grow a richer purple fig, but many other figs don’t ripen here! I’ve had to argue that point on this forum because many people think you can grow any fig in California, but I’m in Northern CA and it’s pretty foggy here. Nothing worse than figs falling off in winter, still unripe, as happened with my Brown Turkey.
Persimmon would probably be Hachiya type, although I’ve never tried an American persimmon, nor even a chocolate type (my Maru grafts haven’t fruited yet), so that could change.
And I’ve had a Katy apricot that is fully mature but will not produce fruit, despite full sun, thus I’ve grafted a million others onto it. I have high hopes for the Nicole grafts this year. I grew up with a Blenheim tree, and there’s nothing like a tree-ripened apricot, but I haven’t had a truly ripe one in decades.
This is coming from a person who has never tasted a jujube, and apparently they are life-changing, so take it all with a grain of salt!
