The ripened rose hip is then placed on a clean cutting board and cut in half to remove the seeds. Place the seeds in a clean container. Add some diluted bleach to kill off any bacteria and fungus spores. You can make the bleach by mixing drinking water with two teaspoons of household bleach. Stir the seeds well before rinsing them and using bottled water to remove all the bleach. To further clean and disinfect the seeds, put them in the container and add some hydrogen peroxide. The seeds can be soaked for up to 24 hours before rinsing them with clean water to clear all the hydrogen peroxide.

can someone help me. I am trying to propagate roses and planted the stems around 5 weeks ago. The stems beautifully grew leaves etc on its own but today when I took out one stem, it has only grown a callus so far. So my question is how long does it take for the roots to grow? When I started I moistened the soil a bit at that time and since then never again. Each stem is in a pot surrounded by a ziplock bag tied to it. All stems are growing leaves. Should I start watering them more often? Would that mean I have to take the bag off every time and then tie it again? Hoping to find some answers from more experienced people.
Once you have had several weeks of below-freezing temperatures, cover the base of the rose with 12 inches of soil or mulch, and then cover the canes with straw, leaves, pine boughs or even foam insulation. Climbing roses can be wrapped right on their supports, or you can lay them on the ground and cover the canes with straw or brush. In severely cold climates, hybrid teas are sometimes partially dug up, laid down onto the soil, and the entire plant is then covered with more soil or mulch.

While your cuttings take root, keep them covered and moist. In a garden bed, a simple DIY mini greenhouse does the trick. Just place a bell jar, a garden cloche or an overturned mason jar over the cutting. A clear plastic bottle with the bottom cut out and the cap removed works, too. Water the soil regularly to keep it moist, but not soggy. Your mini hothouse will keep the humidity high inside.

Pruning: Dead, weak and sickly stems can lead to disease problems. Pruning these away will increase air circulation to the center of the plant and minimize fungus problems. Pruning also stimulates new growth, and allows you to shape the plant in a pleasing manner. Spent flowers should be removed during the growing season to encourage reblooming. Use a scissor-action pruner for the cleanest cuts.
Wonderful instructable! And THANK YOU! I have the most beautiful smelling rose in my backyard that was there when my father purchased the house (I purchased it from him... the house, not the rose, the rose just came with it :) ) and I've never been able to identify it or find anything that smelled nearly as sweet. It blossoms with two buds a year, consistantly, never producing more or growing any further. Both buds are now dead so I think I will cut them off the moment I get home and start this process. Maybe in a couple of years I'll have a whole patch of these magnificent bushes. Again, many kudos and thanks.

Rose seeds need to go through stratification (an artificial cold spell) for 10 to 12 weeks before they will sprout. This, combined with a germination success rate of 20-30% makes propagation by seed an unattractive prospect. on by seed an unattractive prospect. If you still want to try it, find a good source of information that will guide you through the process.
To plant in a garden, choose a spot with bright but indirect light, so cuttings won't be stressed by too much sun or heat. Northern and eastern exposures are perfect rooting spots. Cultivate the soil in your new propagation bed about 4 to 6 inches deep, so it crumbles easily. If your soil is heavy, incorporate a small amount of sand, so that new roots can penetrate without much effort.

Water: Roses require more water than most other landscape plantings, especially during the first year as the plant is getting its roots established. The best way to water your roses is with drip irrigation. It concentrates the water at the root zone where it is needed, and keeps the foliage dry to minimize disease problems. A good, thick layer of organic mulch will help conserve moisture, reduce weeds, and encourage healthy root growth. As the mulch breaks down, it will also add organic matter to the soil.
Choose rose varieties. Did you know there are 13,000 varieties of roses?[1] Some roses grow better in certain regions than in others. When you're choosing what type of rose to grow, take some time to research the specifics of your growing region, then look for roses that have characteristics you find appealing. Take their shape, size, and color into account when choosing varieties to grow. Roses fall into the following categories:
Growing roses from seed can be challenging, since the majority of seeds you collect often won't germinate regardless of your efforts. Fortunately, most rose plants produce a large quantity of seeds inside their rose hips, so it usually isn't necessary to achieve a high success rate. Keep in mind that the plants that grow may be different in appearance or other characteristics from the mother plant, especially if that plant is a hybrid of two varieties grafted together.
Place a jar over each cutting to form a sort of miniature greenhouse for each cutting. It is extremely important that the soil moisture for the cuttings does not dry out at this rooting time. The jar will help to hold humidity in, but can be a problem if it is subjected to a lot of hot afternoon sun, as it will overheat the cutting and kill it, thus the need for shielding against the exposure to the hot afternoon sun when you root roses. Watering of the planting site every other day may be required to keep the soil moist but do not create a standing water or muddy soils situation.
Fertilizer: Roses are heavy feeders, and will benefit from a steady supply of nitrogen, phosphorus and potassium. You can provide these nutrients with either liquid or granular fertilizers, at a ratio of approximately 5-8-5. In most cases, regular applications of compost, rotted manure, fish emulsion and seaweed extracts will provide roses with all the nutrients they need. These organic amendments also help to moderate pH imbalances and stimulate beneficial soil life. Other organic amendments favored by rose growers include greensand, black rock phosphate and alfalfa meal.
