I potted (24" pot) a cheap ã5 pear tree (conference) about 6 weeks ago, which had no foliage at all, and recently i've notied some growth, whih unfortunatly is from pretty much underground.

As this is obviously the rootstock, am I better leaving the tree as it is and seeing what happens, pinching out the rootstock 'branch' or something else?

It would be nice to have this tree 'back to life' but i'm also happy to keep the rootstock for future grafting.

Regards

Nik
