I planted a bunch of Cherimoya seedlings, probably about 60, and none I would say have been doing great since the heat cranked up. I only planted 6 sugar apples, 3 in 60% shade and 3 in 3 hours of morning sun then 80% shade and all of them look fantastic. The tray of soursop are doing pretty good too under 60% shade, and I have 3 bigger ones in morning sun only that look really good as well. You can see the bigger cherimoya seedlings are barely hanging on to life, especially when it hit 120 degrees for 2 days. But you can see that lone sugar apple in the tray full of cherimoyas, behind the 2 bigger sugar apples in pots, is doing awesome.
So I'm wondering in our climate, if I should graft cherimoya budwood onto the sugar apple when it gets bigger. Or will our winter temps in Palm Springs destroy them?
3 Sugar Apples loving the 110-120 degree temps, distressed Cherimoyas in the back.
Soursop/Guanabana doing ok in the heat
Larger Cherimoya seedlings suffering from severe heat distress under 60% shade
Smaller Cherimoya seedlings also no responding well to the heat under 60% shade.
