I have a few potted citrus trees. The small lemon has thorns which I nip off to make it more hospitable. On Monday, I got out the nippers as I noticed some needed trimming from the Miho satsuma. I clipped all the thorns off a limb and stood up to check the new growth at the top when I realized it didn't have thorns.

I looked closer at the thorny limb and believe it is growing from below the graft. The thorny limb is the new growth to the left in the picture.
