Roses are a popular perennial plant loved for their exquisite blooms with delicate petals arranged in multiple layers. One of the most effective methods of propagating roses is by taking cuttings from an existing healthy plant to grow a new rose bush. To propagate by cutting, choose a healthy stem from the plant and place it in soil to root and grow. Another way to propagate roses is through division, but this method requires more effort. To propagate by division, you need to dig up the entire rose bush, split the root system in half, and replant the two halves as separate bushes.
Steps
Propagating roses from cuttings
Choose the right time. Taking cuttings is one of the most common methods of propagating roses. The best time to cut the stem is when the outdoor temperature is warm but not too hot. It's advisable to do this when the rose bush is actively growing. The ideal time of year for this is late spring or early summer.
- Roses can also be propagated in cooler weather, but the process will take longer and the chances of success are lower.
- If you don't have a rose bush to take cuttings from, try asking friends or neighbors.
- You may find wild rose bushes where you can take cuttings to propagate.
- Check with nurseries or garden centers to see if they offer cuttings.
Gather the materials. To propagate roses using this method, select a healthy rose plant and cut a stem. You will need some gardening tools and materials for this project, such as:
- A 5 cm wide plant pot
- Planting soil
- Sharp and sterile cutting tools
- Rooting hormone
- Clear plastic bag or glass jar
Prepare the pot. Fill the small pot with planting soil. For best results, replace a quarter of the soil with materials like perlite, moss, vermiculite, or a mixture of these. This helps improve air circulation and drainage, providing better conditions for the cutting to root. Water the soil if it feels dry and ensure proper drainage for even moisture distribution.
- Instead of a pot, you can also use a jar or the bottom half of a large plastic bottle (cut the top off).
Choose a cutting stem. Pick a mature, healthy plant to take a cutting from. The cutting should be a top stem with at least 3 leaves, preferably one that has recently flowered. Look for a young, yet mature and sturdy stem about 15 cm long.
- It’s better to choose top stems from the outer parts of the plant, as they tend to root better than those from the center or lower parts.
- Stems with buds or flowers can also work, but it’s better to choose one with a flower that is beginning to fade, indicating that the flower has bloomed.
Cut the stem section. The best tool for cutting is a sharp pruning shear or razor blade. Make the cut at a 45-degree angle, just below the lowest leaf node (where the leaf attaches to the stem).
- Be sure to sterilize your cutting tools to prevent the spread of disease.
- To sterilize, you can either heat the tool in fire until it turns red or boil it in water for about 30 minutes.
Remove flowers, buds, and some leaves. Use the cutting tools to remove any wilted flowers and buds at the joint where they meet the stem. Any rosehips on the stem should also be removed.
- Cut off all the leaves on the lower half of the stem.
- Leave 2-3 leaves at the top to aid photosynthesis. Cut the remaining leaves so that each has only half of its surface area left to help conserve moisture.
Making Incisions on the Branch. Making incisions is the process of cutting a few slashes into the lower part of the branch to encourage root growth. Use a cutting tool to make 2.5 cm long cuts on the bark of the branch just below the main section.
- Make 3-4 slashes on the bark to help roots develop.
Dip the Cutting into Rooting Hormone Powder. Dip about 5 cm of the lower part of the cutting into rooting hormone powder, ensuring the powder covers the cut end and the slashes made on the branch. Gently shake off any excess powder.
- Rooting hormone is not essential when cutting and propagating roses, but it enhances the chances of successful rooting.
Plant the Cutting and Water It. Use a pencil or your finger to create a hole about 5 cm deep in the center of the plant pot. Surround the cutting with soil and gently press it down with your hand.
- Water the soil thoroughly to keep it moist.
Cover the Cutting with a Plastic Bag or Glass Jar. If using a plastic bag, insert two sticks about 20 cm tall on either side of the cutting to hold the bag in place. Drape the plastic bag over the plant and cutting, securing the bag with elastic bands or string. If using a glass jar, simply place a large jar over the cutting.
- The plastic bag or jar acts like a mini greenhouse, helping to retain heat, moisture, and UV rays necessary for root development and growth.
Provide Plenty of Sunlight and Moisture for the Cutting as It Grows. Roses need a lot of sunlight each day, but be careful not to expose the plant to excessive heat. Place the plant in a well-lit area with indirect sunlight, especially during midday.
- The glass jar and plastic bag will help maintain moisture in the soil and on the cutting, but make sure to water whenever the soil or cutting feels dry.
- A heating mat placed under the pot can help stimulate root growth.
Dividing Rose Bushes
Choose the Right Time. The ideal time to divide perennial plants is in early spring or late fall. This is when the plant is dormant, which minimizes shock and supports better root growth.
- Dividing perennial plants during dormancy is crucial since the plant won’t be flowering at this time. Avoid dividing rose bushes while they are in bloom.
- Dividing a bush is less common than cutting, as it is more challenging and time-consuming. You will need to dig up the mature plant, split its roots in half, and replant both sections.
Gather Your Tools and Materials. To propagate roses by dividing, you'll need a healthy, mature rose bush along with various gardening tools such as:
- A sharp knife or sterilized pruning shears
- A spade or trowel
- Gardening gloves
- Two large buckets
- Moist newspaper
- A pre-prepared garden area
- Nutrient-rich soil
Select a Healthy Plant to Divide. It's essential to choose a healthy plant to ensure the divided rose bushes will grow well and produce beautiful flowers. A healthy plant should have the following characteristics:
- Plenty of leaves
- Leaves distributed evenly across the entire plant
- Produces abundant flowers
Water the Plant. To minimize shock before digging up the rose bush and dividing its roots, thoroughly water the plant. This step will loosen the soil around the roots, making it easier to lift the plant from the ground without damaging the roots.
Carefully Dig Up the Rose Bush. Use a spade to dig into the soil about 1 meter away from the base of the plant. You need to lift the plant, but avoid cutting into the roots or damaging them. Gently move the soil aside to expose the roots.
- Once you’ve dug around the bush and the root system is exposed, you can carefully lift the plant from the ground.
Cut the Rose Bush in Half. Place the rose bush on the ground or on a wheelbarrow. Use a saw or sterilized knife to cut the plant into two equal halves by cutting through the center of the bush, including the root system.
- To sterilize your cutting tools, you can heat the saw blade or knife over a flame until it’s red-hot or boil them in water for 30 minutes.
Keep the Roots Moist. Once the plant has been divided, place both halves into buckets and move them to a shaded area to protect them while you prepare the planting beds. Cover the roots with damp newspaper to help retain moisture.
- It’s best to maintain around 50% humidity to keep the plant moist without making it too soggy.
Prepare the Planting Soil. Add fertile soil or organic matter to the area where the rose bush was dug up to ensure an abundant supply of nutrients for the newly planted bushes. Use a spade or your hands to mix the new soil and spread it across the prepared ground.
- Suitable organic materials for soil enrichment include well-rotted compost or manure.
Replant the Two Bush Halves. Dig two holes deep enough to match the depth of the old plant in the area you’ve just prepared. The holes should be about 60 cm apart. Plant each half in a hole and cover the roots with soil. Gently press the soil around the roots.
- Water the plants thoroughly.
- Keep the rose bushes moist throughout the first year as they establish their roots.
Taking Care of Your Plant for Healthy Growth
Ensure the Plant Gets Plenty of Sunlight. Roses require 6-8 hours of sunlight daily. When selecting a location for planting roses, look for an area with direct sunlight.
- In hotter climates, it’s best to choose a spot that gets indirect sunlight during the hottest parts of the day (from 10 AM to 4 PM). Areas near large trees that provide shade during the peak heat are also suitable.
- In cooler climates, plant roses in front of a south- or west-facing wall or fence to shield the plant while benefiting from the additional reflected heat.
Water the Plant Regularly. Roses require deep watering, especially during the first year and the hot summer months. Ensure the plant gets thoroughly watered twice a week during the summer to maintain consistent moisture.
- The best method for watering roses is using a drip irrigation system or soaker hose to target water directly at the plant’s roots. Avoid getting the flowers or leaves wet, as they may develop diseases, mold, or rot.
Adjust the Soil with Fertilizers. In addition to needing water and sunlight, roses also require frequent fertilization, especially before and during their blooming period. From April to July, it’s important to feed the plant monthly with nutrients, such as:
- 5-10-5 or 5-10-10 granular fertilizer
- Fish emulsion
- Seaweed extract
- Well-rotted compost and manure
- Alfalfa meal
Prune the Plant Regularly. Roses thrive when regularly pruned, as this helps remove diseased branches, flowers, and leaves, while improving air circulation. In the spring, use pruning shears or scissors to remove dead flowers, sick branches, and wilting leaves.
- Continue pruning dead flowers and leaves throughout the spring and summer as needed.
Advice
- It is easier to propagate roses from cuttings than to grow roses from seeds.
