Keep them in a bright location with indirect light until roots appear through the bottom of the pots. Water with three percent hydrogen peroxide for about a quarter of the waterings to keep the cuttings from rotting. Prop the bags up away from the cuttings, using three or four popsicle sticks stuck into the soil.Ĭheck regularly and make sure the potting medium stays moist, but not oversaturated. Tamp down the soil mix around the stems.Ĭover the pots with clear bags or planter humidity tops. Carefully place the cuttings into the holes in the medium in your prepared pots, to a depth of about three inches (half of the stem length). Moisten the bottom half of each cutting, and dip it in the rooting hormone. You want to avoid contaminating the whole container of rooting hormone with your cuttings. Remove a small quantity from the container and place it in a small dish or paper cup to use for this gardening project. I recommend using semi-softwood rooting hormone powder or gel containing at least 0.4 percent indole-3-butyric acid (IBA) for rooting H. Prepare four- to six-inch pots of moistened soilless potting mix, and poke holes into the center of the mix, slightly wider than the cuttings. Not all cuttings will root, so take three times more cuttings than you want plants. Remove all but the top two to three pairs of leaves. Select branches that are roughly the thickness of a pencil, and take five- to six-inch cuttings at a 45-degree angle directly below a bud. Branches are ready to cut for semi-ripe propagation when they are still green at the tips, and just beginning to harden. Take cuttings in the summer, in July or August, before the new growth on the ends of branches becomes woody. I’ll focus on my favorite method below: semi-ripe stem cuttings rooted in a controlled environment such as a greenhouse or indoors. These include rooting hardwood cuttings, softwood cuttings, and semi-ripe stem cuttings.Ĭuttings can be taken and placed directly in nursery beds or in pots. There are a few possible methods of taking rose of Sharon cuttings. Keep reading for site preparation and planting details. Plant them out in the early fall, or in early spring after all danger of frost has passed. If you do find some small seedlings and you want to transplant them into your own garden, simply dig them up, pot each one in a soilless medium in an eight to 12-inch (two- to five-gallon) pot, and care for them as described below until they’re at least one to two feet tall. TransplantingĪ good starting point if you’re looking to propagate plants is to look around and under existing plants, if you have access to any, to see if any small seedlings are coming up. Hybrid cultivars may not grow true to seed. By layering or taking cuttings, you’ll get a clone, or a plant that’s identical to the parent plant.
