(DESPITE OUR BEST EFFORTS TO HAVE THEM READY EARLIER, IT IS ALWAYS FEBRUARY, SOMETIMES EARLY MARCH, BEFORE WE CAN SEND YOU THE ROOTSTOCKS. THEY MAY THEREFORE BE SENT SEPARATELY FROM THE REST OF YOUR ORDER.)We make virus free rootstock available to the backyard grower who wishes to start his or her own trees. The rootstock is the major factor in determining the size of the tree, its cold hardiness and tolerance of wet conditions. We offer 1/4" caliper rootstocks.
