kumquat: repotting, gritty mix?
Hello all! I recently received a 'Meiwa' kumquat as a gift. It's about 4.5' tall and was in a ~3 gallon container. A few days ago, I decided to transplant it into a ~12 gallon pot. I mixed up about one part of bagged topsoil with compost, one part peat, and a bunch (probably not quite one part) of perlite to make it airy, and top dressed with a bit of composted manure, then mulched with pine straw.
That was before I properly discovered gardenweb, the container forum, and gritty mix. I feel a bit foolish: though I researched before transplanting, I now feel like I used improper media for the job. It wasn't even really the best quality materials. Reading about gritty mix has made me want to go dig up the kumquat and replace the media!
So, though the plant seems healthy and appears to have grown more in the last week or so, I'd like to take care of this before it's too late. Though I know kumquats are pretty hardy, should I risk disturbing the rootzone to move the kumquat to gritty mix, or perhaps another medium?
Thanks so much for any help!
