I'm willing to try grafting, Skeet. the pictorial would be great. thanks in advance.
I'll go look at the tree tomorrow morning. thanks to everybody for helping me!
skeeterbug, I took some pictures of the plant. It is like you said: trifoliate, and many long thorns. [IMG] leaves [IMG] branches [IMG]...
haha. the fruit was actually good when I bought it. the skin was sweet and the fruit was not sour. also, the fruits are larger and much rounder...
I have a kumquat tree that is about 3 years old. when I bought it from the nursery, it had edible fruit on it. now, the plant is about 7-8 feet...
