Rootstock won't affect chilling needs. And I've liked citation for potted trees or inground. Only issue I've had is crown gall. Nemaguard has worked in pots as well and will save you 3 bucks. My mix drains very well which probably accounts for much of Nemaguard's success.

Thanks for the info Fruitnut! Did you have crown gall with citation in pots???

Yes, sure did. But so far I can't tell that it's hurt the tree or production. Have had it with other roots as well but not sure about how much due to small sample size.

Does crown gall occure from planting to deep or is it just one of those things that can happen now matter what you do? Any way to avoid it?

Never mind the last question Fruitnut, i read up on it, thanks again for the info!
