Our Meyer lemon tree has a strong branch low down near the trunk with 3 pomellos growing off it. We're not sure how "the birds and the bees," or maybe it was the bees, made the lemon sprout a new branch to bud pomellos on by mixing pollen in our lemon flowers on legs and abdomen.
Anyone have any theories?
I guess when your branches have spikes this long on them...you think you can do anything. And often, you can.
