Hi,
My name is Angela and I live in Pensacola (NW panhandle), FL.
I am new here and found the forum as I was looking for ways to propagate/grow citrus. Over the last 2 days I have read a bunch of entries here just trying to glean info on where to start. I have learned quite a bit, but I have some basic beginner questions. The answers may be on here somewhere but I have already used too much time sitting here wading through it all

(It's been fun though.)
Currently, I have a kumquat tree, bearing fruit in a about a 15 gallon container that is about 6 ft tall with about a 3 ft spread. It was given to us last spring and we dug it up and it was prolific in fruit this winter. We have no idea what the rootstock is.
1. I am wondering if it would be feasible to graft onto that tree since it is already mature and bearing fruit. I'd like to do some lemon, satsumas, and grapefruit at least. I have a source for meyer lemon and maybe another type as well. I am still looking for a source for the satsumas and grapefruit. Unfortunately, most of my friends with satsumas are over the border in Alabama so those sources are not available to me.
2. So I am also wondering if anyone knows of any sources for cuttings available in Florida, especially in NW Florida.
I maybe overlooking the obvious so please understand that this is brand new to me. Most of my experience is in propagating non-fruiting plants and trees from cuttings and seeds.
Thanks.
