Propagation of already grafted rose plant
Can we use the healthy stems of already grafted rose plant to have another plant but with own roots? I'm from India and English roses are available only in grafted form here. So thought to know about growing new plant with own roots from the cuttings of healthy stems of grafted rose plant.
The point of grafting is to have vigorous roots. You can take stem cuttings but you lose the root vigor. Remember the root stock is mature and can nourish the growing plant better than small roots from a stem cutting. So it will take longer for your cutting to reach mature size and to flower. Some argue that the only purpose of grafting these days is to get roses to a marketable size faster. Rootstock is often hardier and better able to stand temperature extremes than own root.
