Growing rosemary from seeds is difficult, tricky and does not yield the best results. However, propagating it from a mother plant is easy and effective. The first step in propagating rosemary is to buy a good quality healthy mother plant.

Once you bought a rosemary mother plant, leave the recently grown stems and remove the rest. You could distinguish which ones grew recently by their size. The smallest ones in size are usually the most recent grown ones. They have a great growth potential.

Afterward, cut off the bottom leaves from your seedling. It is better to use a scissor or a sharp knife to snip away the bottom leaves. Cutting them off with your hands may be harmful to your plant. Then, moist the seedling in a fresh water. Don’t soak it. Leave it in water until the substantial roots start to grow.

For better results, you could use a hormone rooting powder to boost the growth of the roots. Drench about 1/4 of the cutting into the powder. This will help the seedling to grow roots fast.

2. Choosing a container

Picking a container for rosemary is easy. You will need a container that is at least 3 inches in depth and diameter. Make sure to drill many drainage holes in your container to protect your herb from root rot. Since rosemary prefers well-draining soil, you should use a terra cotta pot rather than a plastic one. Terracotta Pots help the soil drains water fast. Thus, they shield your herb from overwatering.

3. Soil

Rosemary requires a good quality well-draining soil. You should never use soil from your garden as it may contain pests and diseases that could harm your herb. You could make an excellent good quality soil for rosemary by mixing two parts of potting soil with one part of perlite or sand. Pertile will promote a better drainage.

It is also advisable that you add some peat moss to the soil. It facilitates the growth of your plant and improves its yield.

Plant your cutting deep into the soil until the bare stem is fully covered. However, don’t bury the leaves in the soil. Once you plant the seedling, move the container to the sunniest window or spot in your house. Rosemary requires at least 6 hours of direct sunlight exposure daily.

If you cannot provide this lovely herb with adequate access to direct sunlight daily, you should seriously consider investing in grow lights. There are a lot of good grow lights that will replace the lack or the shortage of sunlight. Perhaps, fluorescent grow lights are the best to use with rosemary. Put your plant 6 inches below the grow lights and leave it there for 14 hours per day.

The best way to prevent overwatering that leads to root rot is to check the soil before you water your plant. Poke your finger one inch deep in the soil and if the soil is slightly dry water the plant, if it is not, don’t water it.
