Thirty years ago I transplanted a trifoliate seedling from a fencerow near my home.( My maternal grandparents called them a "hedgeorange"). I planned to use the tree for understock, but I never got around to it. The tree finally started fruiting three years ago. I have planted the seeds from the fruits in pots for understock, but it seems that the barkof the seedlings never get slippery . Seedlings also volunteer all around the tree but so far, I have never had a successful bud on any of the offspring of this tree to live.
They seem to get pot-bound before they even reach pencil-sized. I have tried watering and heavy applictions fo liquid fertilizer on the tree, several days before I plan to work, but to no avail.
Does anyone have any Ideas on how I can cause these seedlings to get slippery bark?
Thanks,
Tom Loeb
