grafting to a root sucker

Question

I started a grapefruit tree from a seed of a hybrid. I want the tree to bear fruit. I saw a root sucker forming on the trunk close to the soil line. Can I graft to the root sucker? It is in its infancy stage, but maybe it will grow larger and could it be used to graft to. Or should I graft to a branch?

Answer 1

Grafting to a sucker may work. I would separate it though and allow it to develop its own solid root system first, otherwise, it would never quite get enough from the mother plant to really do well. If this is not what you want, I would graft to the branch then.
