Hardy and smothered in blooms throughout the summer most floribunda roses are easy to propagate.
Getting new roses the easy way: You can propagate many roses from cuttings, but don’t expect more than a eighty percent success rate especially from climbing roses. As you would be pruning the rose stems any way it is worth having a try.
- In September, choose some green healthy canes that have already become woody. Take some twenty centimetre sections, by cutting just above a bud eye at the top and just below a bud eye at the base. Remove the lower leaves.
- Fill several three litre flowerpots with a mixture of horticultural sand and soil , in a ratio of 2 to 1. Push the cuttings into this mixture with the buds pointing upwards until only the top half of the stems are showing. Keep one variety to each pot and remember to label and place in a shady spot in your garden.
- Water and keep moist until autumn.
- Over the winter protect the cuttings by burying the pots in a trench in the garden or bringing them into a frost-free place in full sunlight.
In the spring when the weather is fair. Water, then transplant the rooted cuttings into your rose beds.
Natural rooting hormone: In the summer, choose a favourite rose and cut off a vigorous non-flower-bearing stem that has not yet become woody. Remove the lower leaves with a knife, leaving a small part of the leaf stalks. Cut a cross in the base of the Stem and insert a grain of wheat in the crack. Soak the stem in a glass of water overnight, and plant into a pot filled with a mixture of equal parts horticultural sand and soil. This treatment will help the plant become established.
Protect the graft in winter: Standard roses are grafted at the top of the main trunk. This graft is exposed to the weather and can be susceptible to frost. In winter cut back the stems at the top of the rose by about half their length and wrap the graft union to protect it.
- A simple way of making a graft cover is to cut the sleeve off an old jumper, slip it over the graft and fill with moss or straw. Gently pat down this protective layer then cover with a plastic bag to keep the rain out.
Bouquet cuttings: If you like a rose you are given as a cut flower by friends, ask them to take a cutting for you in the autumn. Or you could try taking a cutting from the stem yourself. Don’t try to take cuttings from florist roses. These are special varieties of roses, bred for greenhouse production. These roses will not normally thrive in a garden.
DIY ramblers: Save money and bulk up your garden plants by layering any of your roses that have long, flexible stems. In spring, choose a healthy rose stem that is close to the ground. Leave it attached to the plant, but lay it horizontally on the soil. Remove the leaves where the stem touches the ground and carefully make an incision in the bark on the underside of the stem at this point. Cover with a few centimetres of soil leaving the tip of the stem exposed. Peg the stem down with wire and keep it well watered. In Autumn, check to see that the stem has rooted in the soil. Then cut the new rose from its mother with secateurs and replant it.
To ensure strong growing bushy plants from your cuttings do not allow the plant to flower in its first season.
