Dead-heading a flowering plant means to remove faded flowers. The purpose of doing this is to stimulate the earliest possible development of new, young shoots and further blooms throughout the flowering season. On roses, once a rose flower has been fertilized it will soon fade and if left on the plant it may delay the production of new shoots below the old flower cluster.
In some roses, a hip or a seed pod will form after the flower is fertilized and this diverts energy from further flower production. If you don’t need the hips for ornamental purpose then you should remove the dead flowers regularly to keep the rose flowering throughout the summer.
In autumn, even if some of your roses will continue to bloom, do not dead-head them anymore to avoid encouraging new, soft growth which would be damaged by the first frosts. Let the flowers on the plant until the autumn cut-back.
Different types of roses need different methods of dead-heading. On Floribunda Roses, the central bloom of a truss will fade first and should be cut out to maintain the display. Then, when all the flowers have faded, remove the whole truss by cutting back to an emerging bud or a fully formed shoot. On Hybrid Tea Roses cut back stems bearing faded flowers to an outward-facing bud or fully formed shoot.
Also you might find on your roses some blind shoots. These are shoots that develop without a terminal flower bud. They divert plant’s energy just like a sucker. Prune them out as soon as they appear. Cut the blind shoot by about a half to an outward-facing bud to encourage it to grow away and flower. If no but is visible then cut back the whole shoot to the main stem.
There are three types of roses available on the market that you can plant in your garden: bare-root roses, packed roses and container-grown roses. The best time to plant bare-root roses is in their dormant period from late autumn to early winter. Early spring is also a good time to plant in areas that suffer from bad winters. Bare-root roses are in a semi-dormant or dormant state and their roots are virtually clean of soil. You should plant those roses as soon as possible after you buy them.
Remove any diseased or damaged growth, trim any thick roots by about one third, dig the planting hole in a prepared bed and add half a bucketful of organic compost mixed with some general fertilizer into the bottom of the hole. Place the rose in the center of the hole and spread out the roots.
Lay a cane over the hole to check that the bud union is about 2,5 cm below soil level. Fill the hole with soil firming well with your hands. Lightly tread down the surrounding soil, rake over the soil and water well.
