I have been growing a "clementine tree" from seed for about three years now and decided that I might want to experiment with some grafting onto it. So, I went away to try and went way overboard (as is usual). I planted store bought citrus seeds from all of the following in addition to the single clementine plant. I now have at least five seedlings of each below to experiment with:
1 Key lime seedlings
2 Kumquat seedlings (Nagami)
3 Blood orange seedlings
4 Lemon seedlings
I did not want to use grapefruit because of the much larger fruit and long maturation time. My questions now mostly involve "what kind" to graft onto "what kind" for a reasonably good result. What kind might be best for the root stock? Can I graft three or four of these together successfully? I was thinking Lemon/Key lime/Kumquat/clementine together etc. but, I then noticed how many differences there were between the seedlings (vigor, size, and speed of growth). I think I also read that Key limes and Kumquats grow true from seed and bear fruit sooner. Can anyone advise about potential best grafting combination(s)?
I live in the Northeast and will be growing potted plants indoors/outdoors as the seasons permit.
