Roses are popular perennials for their beautiful flowers with delicate layered petals. One of the best ways to propagate roses is to take cuttings from a growing tree to grow into a new rose bush. If you want to grow roses from cuttings, choose a stem from a healthy tree and stick it in the soil to let it grow on its own. You can also propagate roses by separating growing plants, but this method requires more work. To propagate by splitting plants, you must dig up the entire rose bush, cut the roots in half and replant the halves into two separate rose bushes.
Steps
Growing roses from branches
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/fb/Propagate-Roses-Step-1-Version-2.jpg/v4-728px-Propagate-Roses-Step-1- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/fb/Propagate-Roses-Step-1-Version-2.jpg/v4-728px-Propagate- Roses-Step-1-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Choose the right time. Cuttings are one of the most popular methods of propagating roses. The best time to prune is when the outside temperature is warm but not too hot. You should choose when the rose bush is growing healthy. The ideal time of year to do this is late spring or early summer.
- Roses can also be planted in colder weather, but the process takes longer and the chances of success are lower. [1] X Research Source
- If you don’t have rose bushes to cut, try asking a friend or neighbor.
- You can find wild rose bushes to cut branches and bring back to propagate.
- Ask the nursery or gardening center if they will provide cuttings.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/30/Propagate-Roses-Step-2-Version-2.jpg/v4-728px-Propagate-Roses-Step-2- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/30/Propagate-Roses-Step-2-Version-2.jpg/v4-728px-Propagate- Roses-Step-2-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Material concentration. To propagate roses using this method, you need to choose a healthy rose plant and cut a stem. This project requires you to have some gardening tools and materials such as:
- 5cm wide plant pot
- Woodland
- Sharp and sterile cutting tools
- Rooting-stimulating hormone
- Clear plastic bag or glass jar
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/cc/Propagate-Roses-Step-3-Version-2.jpg/v4-728px-Propagate-Roses-Step-3- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/cc/Propagate-Roses-Step-3-Version-2.jpg/v4-728px-Propagate- Roses-Step-3-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Prepare pots. Pour potting soil into a small pot. For best results, replace ¼ of the potting soil with perlite, peat moss, vermiculite, or a mix. This helps increase air circulation and drainage, creating conditions for better rooting. [2] X Research Source Water if the soil feels dry, and remember to let the water drain out so that the soil is evenly moist.
- Instead of growing in a pot, you can also grow in a jar or the bottom half of a large plastic bottle (cut off the top of the bottle).
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/11/Propagate-Roses-Step-4-Version-2.jpg/v4-728px-Propagate-Roses-Step-4- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/11/Propagate-Roses-Step-4-Version-2.jpg/v4-728px-Propagate- Roses-Step-4-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Choose a branch to cut. Choose mature and healthy trees for cuttings. The branch to be cut should be the outer tip and have at least 3 leaves, preferably one that has recently flowered. Look for young but mature and sturdy branches, about 15 cm long.
- It is better to cut the top and outer branches, as these seem to take root better than the middle and bottom branches. [3] X Research Sources
- Branches with buds or flowers can also be used, but you should look for branches with flowers that have begun to fade, indicating that the branch has flowered.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/4c/Propagate-Roses-Step-5-Version-2.jpg/v4-728px-Propagate-Roses-Step-5- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/4c/Propagate-Roses-Step-5-Version-2.jpg/v4-728px-Propagate- Roses-Step-5-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Cut a branch. The best tool for pruning is a sharp pruning shears or a razor blade. Cut the branch diagonally at a 45-degree angle, just below the lowest leaf node (where the leaf attaches to the branch). [4] X Research Sources
- Remember to disinfect cutting tools to prevent the spread of pathogens.
- To disinfect, you can either heat the tool on a fire until it is red hot or boil it in water for about 30 minutes.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a2/Propagate-Roses-Step-6-Version-2.jpg/v4-728px-Propagate-Roses-Step-6- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a2/Propagate-Roses-Step-6-Version-2.jpg/v4-728px-Propagate- Roses-Step-6-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Remove flowers, buds and some leaves. Still use the pruning tool to cut away the wilted flowers and buds at the junction with the branch. Roses, if present on the branches, also need to be removed. [5] X Research Sources
- Cut off any leaves growing in the lower half of the branch.
- Leave 2-3 leaves on top to help the branches photosynthesize. Cut the remaining leaves so that each leaf is cut in half to prevent moisture loss.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b4/Propagate-Roses-Step-7-Version-2.jpg/v4-728px-Propagate-Roses-Step-7- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b4/Propagate-Roses-Step-7-Version-2.jpg/v4-728px-Propagate- Roses-Step-7-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Branch edge. Notching is the act of making a few cuts in the lower part of the branch to stimulate rooting. Use the tool just cut the branch to make several cuts about 2.5 cm long in the bark at the bottom of the branch.
- Make 3-4 cuts in the bark to help the roots grow. [6] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/3a/Propagate-Roses-Step-8-Version-2.jpg/v4-728px-Propagate-Roses-Step-8- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/3a/Propagate-Roses-Step-8-Version-2.jpg/v4-728px-Propagate- Roses-Step-8-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Dip the twig in rooting hormone powder. Dip about 5 cm of the lower part of the branch into the rooting hormone powder so that the powder covers the cut tip and the nicks cut in the branch. Shake gently to remove excess powder. [7] X Research Sources
- Rooting hormone is not required for cuttings and rose propagation, but it does help increase the chances of the stem sprouting.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/78/Propagate-Roses-Step-9-Version-2.jpg/v4-728px-Propagate-Roses-Step-9- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/78/Propagate-Roses-Step-9-Version-2.jpg/v4-728px-Propagate- Roses-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Cuttings and watering. Use a pencil or your finger to poke a hole about 5cm deep in the center of the pot. Put soil around the branch and use your hands to compact the soil.
- Water so that the soil is moist. [8] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d4/Propagate-Roses-Step-10-Version-2.jpg/v4-728px-Propagate-Roses-Step-10- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d4/Propagate-Roses-Step-10-Version-2.jpg/v4-728px-Propagate- Roses-Step-10-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Cover the branches with plastic wrap or cover the glass jars. If using a plastic bag, stick 2 sticks about 20cm high into the soil on either side of the branch to prop up the plastic bag. Wrap the clear plastic bag over the potted plant and tree branch, secure the plastic bag to the pot with an elastic band or rope. If you’re using a glass jar, simply snap a large jar above a tree branch.
- Plastic bags or glass jars act like a tiny greenhouse, helping to trap the heat, moisture and ultraviolet rays needed to help the branches take root and grow. [9] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/85/Propagate-Roses-Step-11-Version-2.jpg/v4-728px-Propagate-Roses-Step-11- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/85/Propagate-Roses-Step-11-Version-2.jpg/v4-728px-Propagate- Roses-Step-11-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Provide plenty of sun and moisture to the branches during the growing season. Rose plants need a lot of sun each day, but don’t let them get too hot. Place the plant in a bright spot with lots of indirect sunlight, especially in the middle of the day. [10] X Research Source
- Glass jars and plastic bags will help retain moisture in the soil and branches, but you’ll need to water every time you see the branches and soil dry out.
- A heating pad placed under the pot can help stimulate root growth.
Separating rose bushes
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/54/Propagate-Roses-Step-12-Version-2.jpg/v4-728px-Propagate-Roses-Step-12- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/54/Propagate-Roses-Step-12-Version-2.jpg/v4-728px-Propagate- Roses-Step-12-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Choose the right time. The ideal time to separate perennials is in early spring or late fall. This period is when the plant is dormant. This will help the plant to absorb shock and improve root growth. [11] X Research Source
- Separating perennials during the dormant period is important because the plant is unlikely to flower during this time. Avoid separating rose bushes while they are in bloom.
- The method of separating bushes is not as popular as cuttings because it is more difficult and time consuming. You will have to dig up the roots of the mature plant, cut it in half, and replant the halves of the bush.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/be/Propagate-Roses-Step-13-Version-2.jpg/v4-728px-Propagate-Roses-Step-13- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/be/Propagate-Roses-Step-13-Version-2.jpg/v4-728px-Propagate- Roses-Step-13-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Gather tools and materials. To propagate roses by separation, you will need a mature and healthy rose plant along with some gardening tools such as:
- Sterilized sharp knife or razor
- Shovel or spade
- Garden Gloves
- Two big buckets
- Moisture newspaper
- A garden is prepared
- Soil rich in nutrients
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/39/Propagate-Roses-Step-14-Version-2.jpg/v4-728px-Propagate-Roses-Step-14- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/39/Propagate-Roses-Step-14-Version-2.jpg/v4-728px-Propagate- Roses-Step-14-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Choose a healthy plant to split. You need to choose healthy plants to ensure that the rose bushes when separated will grow well and produce beautiful flowers. A healthy plant will have the following characteristics: [12] X Research Source
- Many leaves
- Leaves grow evenly on the whole tree
- For many flowers
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/53/Propagate-Roses-Step-15-Version-2.jpg/v4-728px-Propagate-Roses-Step-15- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/53/Propagate-Roses-Step-15-Version-2.jpg/v4-728px-Propagate- Roses-Step-15-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Water the tree. To reduce shock to the rose bush before you dig it up and separate the roots, you need to water the plant thoroughly. This step also loosens the soil around the roots, making it easier to lift the plant out of the soil and without damaging the roots.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e7/Propagate-Roses-Step-16-Version-2.jpg/v4-728px-Propagate-Roses-Step-16- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e7/Propagate-Roses-Step-16-Version-2.jpg/v4-728px-Propagate- Roses-Step-16-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Carefully dig up the rose bush. Use a shovel to dig into the ground about 1 meter from the trunk. You need to dig up the tree, but be careful not to dig into the roots and damage the roots. Use your hands to push the soil to expose the roots.
- Once you’ve dug around the bush and the roots are exposed, you can carefully lift the plant out of the ground.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e5/Propagate-Roses-Step-17-Version-2.jpg/v4-728px-Propagate-Roses-Step-17- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e5/Propagate-Roses-Step-17-Version-2.jpg/v4-728px-Propagate- Roses-Step-17-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Cut the rose plant into two equal halves. Place the rose bush on the ground or in a wheelbarrow. Using a saw or sterilized knife, split the plant into two equal halves by cutting down from the center of the bush through the roots.
- To disinfect your cutting tools, you can either heat the saw blade or knife over a high heat until hot, or boil it in water for 30 minutes.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/be/Propagate-Roses-Step-18-Version-2.jpg/v4-728px-Propagate-Roses-Step-18- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/be/Propagate-Roses-Step-18-Version-2.jpg/v4-728px-Propagate- Roses-Step-18-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Keep the roots moist. Once the plant has been separated, place both halves in a bucket and place in a shaded place to protect the plant while preparing the bed. Cover with damp newspaper to keep the plant moist.
- Ideally, you should maintain about 50% humidity to keep the plant moist but not too wet. [13] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f2/Propagate-Roses-Step-19-Version-2.jpg/v4-728px-Propagate-Roses-Step-19- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f2/Propagate-Roses-Step-19-Version-2.jpg/v4-728px-Propagate- Roses-Step-19-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Prepare the soil for planting. Add fertile soil or organic matter to the site of the rose bush that has just been dug up to ensure plenty of nutrients for the newly planted plants. Use a shovel or hand to mix the new soil and spread it around the plot.
- Suitable organic materials to add to the soil include well-rotted compost or manure.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d8/Propagate-Roses-Step-20-Version-2.jpg/v4-728px-Propagate-Roses-Step-20- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d8/Propagate-Roses-Step-20-Version-2.jpg/v4-728px-Propagate- Roses-Step-20-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Replant the two halves of the bush. Dig two holes as deep as the old tree in the plot you just prepared. The two soil pits should be about 60 cm apart. Plant each bush in a hole and cover the roots with soil. Use your hands to compact the soil around the roots.
- Water the plants with water.
- Keep the rose bush moist during the first year while it is taking root. [14] X Research Source
Care for plants to grow healthy
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d8/Propagate-Roses-Step-21.jpg/v4-728px-Propagate-Roses-Step-21.jpg”,” bigUrl”:”https://www.wikihow.com/images/thumb/d/d8/Propagate-Roses-Step-21.jpg/v4-728px-Propagate-Roses-Step-21.jpg”,”smallWidth” :460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Make sure the plant gets plenty of light. Rose plants need 6-8 hours of sunlight a day. When choosing a location for your roses, look for a spot with lots of direct sunlight.
- In hot climates, you should choose a location that can receive indirect sunlight when the sun is at its strongest (between 10 a.m. and 4 p.m.). A location near trees that provide shade during the hottest part of the day is also suitable.
- In cooler climates, plant your roses in front of a south- or west-facing wall or fence so that the plant is sheltered and receives additional reflected heat. [15] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b3/Propagate-Roses-Step-22.jpg/v4-728px-Propagate-Roses-Step-22.jpg”,” bigUrl”:”https://www.wikihow.com/images/thumb/b/b3/Propagate-Roses-Step-22.jpg/v4-728px-Propagate-Roses-Step-22.jpg”,”smallWidth” :460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Water the plants regularly. Rose plants need to be watered deeply, especially during the first year and during the hot months of summer. You need to water the plant thoroughly twice a week during the summer to keep the moisture constant.
- The best way to water rose plants is to use a drip irrigation system or permeable hose to concentrate water on the base of the plant and its roots. Flowers or leaves can become infected, fungal or rot if wet. [16] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/fb/Propagate-Roses-Step-23.jpg/v4-728px-Propagate-Roses-Step-23.jpg”,” bigUrl”:”https://www.wikihow.com/images/thumb/f/fb/Propagate-Roses-Step-23.jpg/v4-728px-Propagate-Roses-Step-23.jpg”,”smallWidth” :460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Adjust the soil with fertilizer. In addition to the need to receive plenty of water and light, roses also need to be fertilized regularly, especially before and during flowering. In the spring and summer from April to July, you should add nutrients to the plant every month, for example:
- Granular fertilizer 5-10-5 or 5-10-10 [17] X Research Source
- Fish protein fertilizer
- Seaweed Extract
- Compost and well decomposed manure
- Alfalfa powder
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/ea/Propagate-Roses-Step-24.jpg/v4-728px-Propagate-Roses-Step-24.jpg”,” bigUrl”:”https://www.wikihow.com/images/thumb/e/ea/Propagate-Roses-Step-24.jpg/v4-728px-Propagate-Roses-Step-24.jpg”,”smallWidth” :460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Prune the tree regularly. Roses do well with regular pruning, as pruning removes infected branches, flowers and leaves, and increases air circulation. In the spring, use scissors or pruners to remove dead flowers, diseased branches, and wilted leaves. [18] X Research Sources
- Continue to cut off dead flowers and leaves throughout spring and summer if necessary.
Advice
- It is easier to propagate rose plants from cuttings than to grow roses from seeds.
