we have a way of growing morel mushrooms indoors and we use the apple trees to train the morel mycelium and to provide them with a symbiotic relationship from the start. as these trees age they grow to large for our indoor grow chamber, we must sell them when they become to tall. each tree has been producing morel mushrooms for 2 seasons at least, so the fear of non production is not a thing. With over 12 species of apple trees and 18 species of morel mushrooms we are sure to have a tree for your back yard
