fast growing trees--i ordered a 4 in 1 apple tree early 12, it arrived march 12 and i planted it. had a few blossoms on the granny smith branch. had a hard frost 3 weeks after planting it, the blossoms turned black anf fell off. watched through the summer and i contacted fast growing trees and told them it died. they said they will be sending me a replacement in april 13. i believe the hard frost killed the tree, but of course, the hot summer we had didn't help any.
i also ordered a 3 in 1 plum tree in may of 12 and it is doing well, i expect a few plums in 13. i have had only positive experience with the company. thats about it.
