http://www.raintreenursery.com/Rootstocks/ This is where I ordered mine .Jerry. My plan is to order rootstock, and apple scions this year. ANd use the peach and cherry trees I already have for scionwood. Oh and pear as well. I am struggling with what rootstock to buy, as there are so many companies, and they seem to offer different stock. I know my peaches and pears were grafted on roostock and they have all done well here... just don't know what was used.
Apple scions, about 40 min north of me. Minimum of 4 at $3.50 each totalling $14. Includes shipping. Limited time to order, as these need to collected during the dormant season of winter. http://www.towerhillbg.org/files/3213/6501/4578/th_scionwood_ord08-09.pdf
