You can, but if it is a hybrid tea the resulting plant is unlikely to be satisfactory. Certainly not the same form or habit as that from which the seed came. Species roses are fine from seed but a very lengthy process.
I would go for cuttings, but again, if a hybrid tea it will not perform the same as the parent rose. To achieve a near identical plant you need to bud graft onto a root stock. Species roses and those grown on their own roots are fine for propagating from cuttings, but as mentioned, those budded onto a rootstock will not produce the same growth and habit as the parent.
I would recommend taking hardwood cuttings in the autumn. Make at about 20cm in length cutting at an angle away from a bud at the top of the cutting and straight across just below a node at the base. Strip away the lower leaves and place about 10cm apart and two thirds in depth in a slit trench with a little coarse sand or fine grit at the base. Use hormone rooting powder if preferred. Insert in a sheltered part of the garden and If winter weather is usually severe mulch around and cover with straw or leaf-mould while it lasts - alternatively insert into a cold frame. Softwood cuttings may be taken in early to mid spring and rooted in a propagating case at a temperature of around 24C. with bottom heat. Also, summer cutting can be taken. Choose soft new shoots taken nodally or internodally. Provide a clear plastic cover lightly shaded, as maintaining humidity is essential. Also, short young shoots taken with a heel of parent wood, trimmed and inserted into a propagator or under a lightly shaded plastic cover in early summer. My Website |
