Sunflowers, herbs, and a variety of other plants are simple to grow. Most herbaceous plants can be multiplied by spreading seeds, dividing bulbs and tubers, or initiating cuttings from the stems or leaves (plants without woody stems). Because of their woody stems, roses require a little more effort to propagate, but they’re a terrific way to add to your landscape without breaking the bank.
What You Should Know Before You Begin
The finest roses for this type of propagation are wild roses, often known as “species roses,” most shrub roses, and native roses. Because many hybrid roses are grafted, or made by fusing the branches of a rose that doesn’t perform well onto the rootstock of a hardier one, they can be challenging. Cuttings taken from hybrid plants will never grow those tough roots.
Hybrid cuttings, on the other hand, can grow on their own roots. If you’re trying to propagate hybrids, it’s a good idea to take numerous cuttings because many won’t make it. Also keep in mind that the majority of hybrid roses are patented. You can grow them for yourself, but you can’t sell them until the patent expires or the breeder gives you permission.
Do you have any doubts about whether or not a rose has been grafted? Underneath the top growth, look for a protrusion. It should be above the soil line in a potted plant.
How to Tell the Difference Between Native and Shrub Roses
Wild roses are wildflowers, which means they develop without the assistance of humans. The majority of wild roses have single blooms with five petals apiece.
Single, five-petaled flowers can also be found on native roses. The majority are tiny, wandering shrubs with canes that are two to three feet long. The Carolina rose (Rosa Carolina) and the swamp rose are two frequent indigenous (Rosa palustris).
Shrub roses are sprawling plants that can reach a height of 15 feet in any direction. They have clusters of blooms, and some are hybrids, according to the American Rose Society. Despite the fact that shrub rose hybrids develop on their own roots, woody stem cuttings are frequently used to propagate them.
When Should You Use Stem Cuttings to Procreate a Rose?
The cold fall months are ideal for starting roses from cuttings. That might be as early as September or as late as February in some areas. Begin before all of the flowers on the bushes have dropped, so you can identify each rose and label the cuttings.
Make the cuts early in the morning or in the nights when the weather is cool. Bring a bucket of water with you to keep the cuttings contained.
What You’ll Require
- Pruning shears or a sharp, clean knife
- One or more healthy, mature rose bushes
- Hormone that promotes rooting (the powdered form works best)
- Pots in small sizes
- a dibble or a pencil
- potting soil for roses
- Bags made of clear plastic
- Ties with a twist
From Cuttings, How to Grow a Rose Bush
- Choose new stems that have just stopped blooming and are about the diameter of a pencil. Using a sharp knife or pruners, make 6 to 8-inch cuttings at a 45-degree angle.
- Cut the stems slightly below a node and remove the bottom leaves (the spot where a leaf attaches to the stem). Make four slices with a knife about 14 inches up from the bottom of the stem. This divides the stem’s end into quarters. (If desired, dampen the split ends and dip them into rooting hormone powder.)
- Fill tiny pots with rose potting mix and the cuttings. Pushing them in will cause the hormone to rub off. Make a hole with a pencil or a dibble and place the chopped end in it. Fill the hole with potting mix, gently firm it down, and water thoroughly.
- To protect the bags from contacting the cuttings, place the pots in clear plastic bags and add a few twigs to the mix. Twist ties close the bags, leaving a tiny opening for ventilation. Check the cuttings frequently to ensure that the mix remains wet. Make sure it doesn’t get soggy.
- If you haven’t previously done so, label the cuts. Keep them near a grow light or a bright window out of direct sunlight.
- Give the cuttings a gentle twist after two to three weeks. You’ll encounter some opposition after roots have developed. When fresh leaves sprout on the stems and roots have formed, they’re ready to transplant.
- Place the rooted cuttings in 6-inch rose potting mix pots. Harden them off by exposing them to the elements—sun, rain, and wind—for a greater period of time each day over a period of 7 to 10 days before moving them to a permanent outdoor site.
It could take a few years for the cuttings to bloom. Meanwhile, unwind and anticipate your lovely new roses.
