Many aromatic plants are in use in our everyday life. Mint, Coriander, Curry leaves, Rosemary, Sage, Thyme etc. We are gonna be covering lots of culinary herbs. Their propagation and growing ofcourse. In this post we are going to focus on Rosemary and how to propagate and grow it. Shall we?
Rosemary Cutting
PropagationRosemary can be propagated by seeds and by stem cuttings.
From seedsRosemary seeds are slow to germinate so if you are the impatient kind, stay away from rosemary. It takes somewhere between 20-30 days to germinate. Sometimes faster . The germination rate is also not great. So sow little more than what you plan to grow. When the plants do germinate, take care of them by putting them in a loose well drained mix . Rosemary hates lots of water and very cold weather. The growth rate of rosemary from seeds is very slow, by the time you harvest the leaves the first time, it will be almost an year. Nevertheless growing from seed is fun.
From Stem Cuttings:Propagating a plant from cuttings is always fun. With a little bit of patience and good inputs needed for cutting, one can always achieve almost 100% success. Rosemary is very easy to propagate from cuttings. Here are the list of items you need to do a propagation from cuttings
- Healthy Rosemary mother plant
- Rooting Hormone
- Sharp knife/scissors
- Potting soil
- Small cups/Propagation Trays
- Water.
Choosing a cutting:Choose a healthy mother plant that is free from diseases etc. Take few stem tip cuttings like the one in the picture below. Take out the last pair of leaves from the bottom of the stem. Ensure that there is a node at the step tip. Roots start from the leaf node. You can see there is a node (where leave joins the stem) at the end of every stem.

Rooting Hormone:Rooting hormone is a substance that encourages root formation in cuttings. It is naturally occuring in plants. It is also synthetically produced for propagation purposes. Indole -3-Butyric Acid is a rooting promoting hormone. There are several products in the market. This time I used a product called “Rootomax”. It is a mix of IBA and Humic Acid.

Potting soilFor propagating cuttings, all you need is a sterile mix that drains well. There is no need for any fertilizer at all. However a dash of compost wont hurt. The following are good candidates for propagating cuttings. Cocopeat, Perlite, Vermiculite, Sand, Cocohusk or even regular soil.
Take good a container and fill it with potting media up to an inch or two from the top.Ensure the mix is draining well and also the container you have taken has a drainage hole. Water should not be stagnant in the container at all.

Now take the cutting and dip the end in the rooting hormone. Ensure the bottom node is properly covered with the hormone powder. Then you can stick it in the potting mix. Once you have stuck all the cuttings, give it a nice watering. The right time to do this is either in the evening or morning.
Remember the cover it up and form a dome to keep the humidity in. Covering with a dome is required with most of the plants. This saves from the plant from dehydrating and keeps it fresh. Rosemary is a little bit different. Since it hates lots of moisture, you may want to remove the cover after a week or so. Just don’t keep it in the hot sun since that will make the plants wilt. After, say a week or two later, you can remove the cover. Keep an eye on the cuttings every day and watch for any rotting or browning of leaves.

The cuttings should root approximately in 2-3 weeks. In winters, the rooting may take a little more time than summer.Patience is the key. Just check for roots coming out of the bottom of the cup. If you had used a pot or something like that, gently pull the stem and if the plant offers resistance then it has roots! Yay!
If everything goes well, you will get this

Now that the cutting has rooted, all you need to do is find a home for the cutting and pot it up. Next time you visit your garden, don’t forget to take a pinch of rosemary leaf and enjoy the aroma!..
What herb should we post about next? Sage? Thyme? Got a suggestion ?
