witch hazel dilemma
I have three witch hazels in the garden growing in a triangle (naturally known as the Three Witches) two, H. 'Pallida' and H. vernalis.'Sandra' are doing well, but the third which is the older of the trio and a deep burnt orange colour, inherited from the previous owner, has suffered neglect and the graft is in danger of being overtaken by the rootstock which I guess is H. virginiana.
The graft is the branch lower right, everything else is rootstock. This was photographed before the long summer grass around its base was cleared away and a mulch applied. Annoyingly, the rootstock is now (late September) in flower, although lacking any scent.
My dilemma is, should I prune out all the rootstock and give the graft a chance which will result in a very lopsided shrub?
leave as is and accept that H. virginiana is not the most exciting of witch hazels?
cut back the rootstock and attempt to take some grafts from the surviving piece to graft onto the rootstock stumps?
Any suggestions gratefully received!
