The germination rate for rosemary plants propagated from seed is very slow and note that the layering method is pretty much the same as the cutting method. It’s really rare to find rosemary being propagated from seed since this is a long process.
Propagating rosemary from cuttings doesn’t need much experience, and it is quite easy. You should have dozens of rosemary in no time at no cost at all if you have it propagated the right way. So, here is how to propagate rosemary from cuttings.
Materials Needed to Propagate Rosemary
- Rosemary cuttings
- Terracotta pots or a growing area with some potting soil
- Rooting powder (optional)
- Plastic ziplock bag
- Peat free multipurpose potting mix
Step 1: Source For Rosemary Cuttings
The first stage to propagating rosemary from cuttings is to of course source for the rosemary cuttings.
You have to take a decent size cut from the plant parent, 4-6 long sprigs will be okay. It should be a healthy stem that has been planted the previous year, if you are already growing your rosemary plant then this should be a problem, or you can ask for one from a friend.
Some grocery shops or farmer markets also sell packs or bunches of fresh rosemary plants, so you can get them from them if you can’t find any from your garden or a friend. Fresh rosemary that the stems are becoming slightly woody is ideal for propagating.
Step 2: Prepare The Cuttings
You can choose to prepare your potting mixture for propagating the rosemary plant. The potting mix doesn’t have to be rich in nutrients but has to be with good drainage. However, the next is to remove the rosemary leaves from the lower ends of the stem, you will need about 2 inches of the bare stem.
Discard the end piece you just cut off and if you are ready to propagate right away, using a sharp knife, cut the tip of the sprig at a 45-degree angle and leave the base off for future roots, it should be a minimum of 4 inches long. The striped leaves should be about 2 to3 inches long.
Step 3: Stimulate The Rooting Structure
The rooting is another very important step. You simply have to take the rosemary cuttings and place them in a well-drained potting mix, and they can develop roots all on their own, but you can also dip into a growth hormone.
This process makes rooting fairly easy but not to worry, most rosemary cuttings will root without this hence why it’s optional.
Have your pots filled with the potting mix and slid each of your cutting into the pot along the outer edge. You can also place it in a glass of water if you are not establishing the root of a growth hormone. Place it in a glass of water with 2 inches of the bare stem fully submerged. You should have new roots sprout in 3 to 4 days.
Step 4: Propagate Rosemary
After the root system has been established, and it has been arranged in the pots, the growth will depend on the care system, so you have to give it a good drink of water and a good drainage system as well. To help the cuttings retain moisture, you can place a plastic bag or wrap it over the pot.
You should have a good root system in 4-8 weeks, and you have to keep the soil moist during this period. When you see roots coming out of the drainage hole then you know your rosemary is deeply rooted.
Step 5: Harden The Plants
Your rosemary plant should be ready to grow on its own as a new plant in 6 to 8 weeks but first, you have to harden the plant. The growth rate will depend on the time you are propagating, but you can shock them if you move prematurely, so you have to harden the plants. Young rosemary plants are hardened by being placed in the sun outside and bringing it in at night for a week.
Step 6: Caring For New Rosemary Plant
When a new rosemary root has been propagated, you have to care for it the right way, and first, you have to separate the plants and place them in new pots, so they can grow on their own.
Gently have the plants teased apart to separate them, and it is time to start treating them like any young plant. So place in an area with full sunlight and water, best to keep the top of the soil damp.
