I had fruits in three occasion,off my Desert King.
John:
:The Breba fruits are large sweet and flavorfull.
The problem is how to keep the fruits buds from freezing during winter,because they are formed in the Fall.
In my climate,is impossible to keep fruits buds alive if the tree is inground,as the buds are more sensitive to cold than,the tree itself.
If frozen breba will fall out,and the tree will be fruitless,except a few main crop fruits,that manage to persist,but they will taste like cardboard,when ripe!
Of course every 5 years or so,there might be an unusual warm winter and Spring,and the Desert King might keep the buds and grow them to maturity,even if inground.
If you really want one:keep it in a large pot.or a medium pot,but bury it when you take it out in the Spring.
Also you will have to ,protect it in April,and May,by covering it with a blanchet or something,if frost is announced.
