Grafted apple trees with no growth above the graft
I just joined the forum and have a question. I have very little knowledge about grafting, so please bear with me! My wife and bought seven grated apple trees from the HOS in March of 2012 and after planting them a few months later, several have not grown above the graft, only below it. (One, the Gravenstein, has just a little growth above the graft and more below.)
Should I keep the ones with no growth (or very little) above the graft? Is there any future for them? If so, should I just let them grow or deal with them in a particular way?
Any help would be greatly appreciated - thanks!
I should mention we're in Portland, OR
