Blossom Tree And Cherry Tree Combined

Question

I had a cherry blossom tree in my garden which was nearly dead 10 years ago and it came back to life with care. I Planted a cherry tree around 6 years ago In the garden. This year the blossom tree began to flower and I then noticed that The back part of the blossom tree was still bare. Within the week I then noticed it day white flowers instead of pink and then I looked closer to realise there was a lower branch of the tree which looks like it’s a cherry tree branch on a blossom tree and don’t know how that happened. Could you shed some light on how it could be like this as we have done noting but water the trees. I look forward to hearing from you regards Suzanne

Answer 1

Yes, that is a sucker from below the graft point. What fruit it will bear may not be edible, or palatable.

I would remove it, as it may sap valuable nutrients from your tree. This can lead to graft failure, or the killing off of the scion, or top of the tree.
