Yes, you can easily propagate Rose of Sharon (Hibiscus syriacus) from cuttings, a simple process that involves taking a stem cutting in spring or summer, dipping it in rooting hormone (optional but helpful), and planting it in a moist, soilless mix or even water, keeping it in indirect light until roots form, which usually takes a few weeks to a couple of months.
If you want another of your seedless bushes, or if you just don't want to go through the ordeal of collecting seed, you'll be happy to know that rooting rose of Sharon cuttings is extremely easy.
Plant your rose cuttings
No matter the location you choose, make sure the soil is loose, able to drain and at least 4 to 6 inches deep. Use a pencil or something similar in size to your rose stems to poke holes in your soil and create spaces for your cuttings that are about half the length of the stems.
Cut off all roses and most of the leaves, take the cutting and wound the stem (as in cut it a little at the bottom), put some rooting hormone on it then plant that part into the soil. After doing that cover it in either plastic or a mason jar of sorts. Let it start to root and you'll be good to go.
Rose cuttings should be taken from the current year's growth. You can take flexible, softwood rose cuttings of very new growth in late-spring and summer – these root quickly and easily. Semi-hardwood cuttings are taken in late summer and early autumn, when new stems are firmer and more mature.
Cut each stem into 6- to 8-inch lengths, so that each cutting has four "nodes" — that's where leaves emerge on stems. Keep cuttings moist at all times. Remove all the leaves except one set at the top of each cutting. This helps cuttings root and helps you gauge their progress.
Use a clean, clear glass jar or vase for observation. Change the water every two to three days to prevent stagnation and bacterial growth. Place the container in bright, indirect sunlight, avoiding direct exposure, which can stress the plant. Rose cuttings usually take about 2–3 weeks to develop roots.
Baking soda is used for roses mainly as a natural fungicide to control diseases like powdery mildew and black spot by creating an alkaline environment, deterring pests like aphids, and sometimes to adjust soil pH for nutrient absorption, though its benefits for boosting blooms or acting as a fertilizer aren't scientifically proven, requiring careful, sparing application to avoid harming the plant.
Several cuttings may be placed together in one container. Be sure to add fresh water as needed until the cuttings are fully rooted. Rooting will generally occur in 3-4 weeks but some plants will take longer. When the roots are 1-2 inches long or longer the cutting is ready to be potted up.
Rose of Sharon can be cut down to the ground and grow right back. Rose of Sharon (hibiscus related but hardier in colder zones) You can cut it down to size in the fall. New flower bugs grow around January so no spring pruning if you want flowers!!!
Common mistakes when propagating cuttings include using dull/dirty tools, taking cuttings from unhealthy plants or at the wrong time, overwatering (causing rot) or underwatering (causing dehydration), improper light/temperature, using the wrong soil, skipping rooting hormone for tough plants, and failing to harden off or transplant properly. Avoiding these issues by using clean tools, selecting healthy material, ensuring appropriate moisture, and providing correct aftercare is key for success.
To transplant ROS:
Plant Rose of Sharon in the spring or early fall, spacing them 6' to 10' apart. Choose a location with full sun and nutrient-rich, well-draining soil.
Alternatively, propagate your Rose of Sharon cuttings in water. Some gardeners like to start the cutting off in just a clear glass or plastic container of water rather than planted in compost. What's good about this is you can see the roots form.
The short answer is that eggshells aren't particularly good or bad for roses. While they can supply a minimal amount of calcium, it takes a long time for the nutrient to actually be absorbed by the plant when delivered via eggshells. It's also unlikely that your soil has a calcium deficiency.
Key Points. Banana peels can make your roses healthier by giving them nutrients like potassium and magnesium. You can put chopped banana peels right into the soil to help your roses grow better. Making a banana peel tea is another way to feed your roses without adding waste to the compost.
'Adding coffee grounds to your rose of Sharon plants is a good way to lower the pH,' Tricia adds. In addition, you can apply a soil acidifier or garden lime, which will also lower the pH. Soil test kits like the one listed above will also reveal if your soil is lacking in any other nutrients.
When should you take rose cuttings? Roses have one of the longest cutting periods. So, as long as a rose is healthy, you can take cuttings anytime between May and December. Just make sure that your cuttings are coming from this year's growth and not older stems.
The "5-leaf rule" for roses is a deadheading technique: find the spent (dead) bloom, trace the stem down to the first set of five leaflets, and make a 45-degree angle cut just above that leaf set to encourage strong, new growth and more flowers. This method redirects energy from seed production to healthy shoots, keeping the bush tidy and productive.
Improper Moisture Levels
Too much and too little water can cause rotting or withering issues. If you notice the rose leaves turning yellow and mushy, or they're dry and crunchy, it may be a problem with the soil moisture levels. Though the leaves need humidity, the rooting stems appreciate a light, moist soil culture.
Place the rose cuttings in moistened potting soil mixed with 50% perlite. You can even put multiple cuttings in one pot and split them apart after several months when they are well rooted.
Add a Pothos! I'd heard of using willow as a natural rooting hormone (no idea where to source that however), but didn't know Pothos has this 'super power' too! Just pop a Pothos cutting in with the water with your slow-to-grow cuttings and it helps speed up root development. That's a big yes please.
