Sorry to hear about the failure
and thereâ€™s little that can be done right now
without dormant scion wood. â€˜Stone fruit,â€™ which includes cherries, are tuff candidates for dormant grafting, sorry to say. Theyâ€™ve a bit better â€˜takeâ€™ when â€˜bench graftedâ€™ to small rootstock (as yours were) than â€˜topworkedâ€™ onto an exiting (larger) tree. Most stone fruit are budded in nursery rows, in August. In fact, most fruit trees are budded, as opposed to â€˜what we doâ€™ at the Propagation Fair
That said, below is likely your next best opportunity to salvage the rootstock and come up with the varieties you want â€“ and - itâ€™s free! Youâ€™d pot up your rootstock and bring them to the budding workshop; youâ€™d get a bud-stick from one of the cherry varieties at the Arboretum; then learn to bud or have it done â€“ adding a bud to your cherry rootstock/s, likely below any new growth.
The bud doesnâ€™t put on a lot of growth, occasionally youâ€™ll get no growth at all, but if it takes â€“ youâ€™ll know, and it will be set
of grow next spring. Just pot them for now and let them â€˜grow.â€™ That will beef up their root system and keep the trees (alive) healthy until budding. I wouldnâ€™t suggest going back for another bench graft
next March â€¦though weâ€™d (Iâ€™d insist we) do it for freeâ€¦
Here you go: Budding Workshop
"Saturday, August 6, 2011 - 9:00 AM at the HOS Arboretum
Class starts at 9:00 AM, there is no charge. Following the class will be a summer pruning demonstration, fruit tasting and ending with our annual summer potluck."
