Maybe I should buy an industrial freezer and keep the trees in pots 🤔
Remember you don't actually want them below freezing. Max chill occurs in mid-30s to upper 40s. So more like an industrial refrigerator.
It's always funny how we all want what we can't get. Here I am in the PNW with the highest chill of any zone 9a in the country, but I just wish I could grow a mango tree in my greenhouse. But even the greenhouse gets too cold in winter.
Peaches grow well here, other than PLC and lack of heat units to really sweeten them up. I got nearly 3000 "Utah chill units" from September to March this year, and my peach tree flowered prolifically, before PLC set in (in April) causing it to lose most the leaves and drop all but a few fruit. New healthy leaves are replacing the lost ones, so maybe it'll hold a few fruit and I'll get my first homegrown peaches this year.
Maybe someone in good peach growing climate and someone in good mango growing climate could set up a fruit swap? 😂
