If you’re like most people, you probably think of rosemary as just a herb used in cooking. But did you know that this fragrant plant has many other uses?
Rosemary is a great addition to any garden, and it’s also been used for medicinal purposes for centuries. And if you’re looking for a plant that’s versatile and easy to grow, rosemary is a great option.
There are several ways to propagate rosemary. In this article, I will focus on the three easiest and most common methods:
- Stem cuttings
- Layering
- Division
3 Simple Methods to Propagate Rosemary
Method 1: Stem Cuttings
Stem cuttings are simply cuttings taken from the stem of an existing rosemary plant. I found this to be the easiest and most successful method of propagation, especially if you are new to gardening.
To take stem cuttings, use a sharp knife or pruning shears to cut 4-6 inches (10-15 cm) off of a healthy stem. Make sure that the cutting has several sets of leaves and that there are no flowers on the stem.
Next, remove the bottom leaves so that you are left with a bare stem. Dip the end of the stem in rooting hormone and then plant it in a pot filled with well-draining soil. Water the soil and place the pot in a bright location but out of direct sunlight.
Keep the soil moist but not wet and in a few weeks, you should see new growth. Once the plant is established, you can transplant it to a larger pot or into your garden.
GreenTumb Tip: Choose cuttings that are from the current season’s growth. These cuttings will be less likely to rot and will have a better chance of taking root.
Method 2: Layering
Layering is another easy method to propagate many types of plants, including rosemary. It’s a process where you allow a stem to grow roots while it is still attached to the parent plant.
To layer a rosemary plant, find a healthy stem that is not too woody and bend it down to the ground. Use a sharp knife to make a small cut in the stem and then cover the area with soil. Water the soil and wait for the plant to form new roots.
Once the plant has rooted, you can cut it away from the parent plant and transplant it to a pot or your garden.
GreenTumb Tip: Use a clear plastic bag to cover the soil after you have cut the stem. This will help to keep the soil moist and will speed up the rooting process.
Method 3: Division
Another easy way to propagate rosemary is by division. This is a process where you divide an existing plant into two or more smaller plants. If done right, the plants will not suffer any set-back and will continue to grow and thrive.
To divide a rosemary plant, carefully dig up the entire plant. Use a sharp knife or garden shears to divide the root ball into two or more sections. It’s critical to be sure that each section has several roots and at least one stem with leaves.
Plant each section in its own pot or in your garden and be sure to keep the soil moist but not wet until the plants are established.
GreenTumb Tip: Division is best done in the spring or fall. This will give the plant time to adjust to its new location before the hot summer sun or cold winter temperatures arrive.
How to care for your newly propagated rosemary plants
Once you have successfully propagated a new rosemary plant, it’s important to know how to care for it properly. Here are some tips to help you get started:
Sunlight Acclimation: Gradually acclimate your plant to direct sunlight. If you have been growing your plant indoors, slowly introduce it to direct sunlight over the course of a week. This will help to prevent sunburn and will help your plant adjust to its new environment.
Watering Cuttings: Allow the soil to dry out completely between watering. Overwatering is one of the main reasons that cuttings fail to root. Once established, water your plant when the top inch (2.5 cm) of soil is dry to the touch. Be sure to water at the base of the plant and not on the leaves to prevent fungal diseases. Rosemary shrubs prefer well-drained soil and will not tolerate wet or soggy conditions.
Fertilizing Cuttings: Once your cutting has rooted and is growing well, you can begin to fertilize it. Use a balanced fertilizer and apply it according to the package directions. Be sure to fertilize sparingly as too much fertilizer can damage the young plant. Rosemary plants are not heavy feeders and only need to be fertilized a few times a year.
Final Thoughts
Propagating rosemary is a simple and rewarding process. No matter which method you choose, you will be able to enjoy the fragrant scent and flavor of this versatile herb in your cooking.
