Red apples on one side yellow on the other........First time I saw this, I thought the wine the night before might be getting me:) all the best

Answer 4

Grafting is used when you want vigorous growth, most roses are grafted onto another rose for their root stock. Also fruit trees.

Answer 5

Own root means it's growing on its own, original roots.  

Grafted mean that the part you like, or see, has been cut off of its own roots and put onto the roots of a hardier tree so that it can tolerate colder temps. or adverse conditions.  You can often tell where the graft is on the trunk because there is a large ring of growth on the lower part of the trunk, normally just over the roots.
