Just for the fun of it I threw a kumquat seed in a pot, and it has actually grow quite a bit. I know you should ideally graft cuttings onto rootstock and not start from seed. But I just did it for the fun of it.
Now I wonder if I should start pruning it? When I transplanted It to the current pot I cut the top of cuz I lost many roots moving it, so it has now got two main branches. While it has grown quite tall (about 1meter) it's not thicker than a pencil.
Should I cut it down, or let it continue growing?
