How to Grow Rosemary from Seed? Step by Step Guide

Rosemary is one of the most fragrant herbs you can ever find. A native plant in the Mediterranean, rosemary has many uses other than cooking. You can use it as a natural air freshener, as an essential oil, and as a tea.

Because rosemary grows as a small shrub, you can plant it in front of your home. It’s an attractive display so you can also use it as a garden decoration. This plant can grow up to three feet tall and 5 feet wide. The bonus part is you can use it to control pests in the garden.

Unfortunately, rosemary does not do very well in very cold situations. So if your area experiences even just mild winters, your garden may not be truly suitable for growing rosemary. You can maybe still grow it, but it will be a bigger challenge. 

Many people fail at growing rosemary. It’s because it’s one of the more difficult herbs to grow, unlike other herbs such as basil. You can cut the stems of rosemary and propagate them. However, there’s a high chance your rosemary may die. That’s unless your clump is mostly fresh and leafy. For better and safer results, plant the rosemary seeds instead. Here’s how to grow rosemary from seed.

How to Grow Rosemary from Seed

Step 1: Fill your pot with well-drained or loamy soil. Rosemary naturally grows in sandy or rocky soil. Sprinkle your seeds then add another half an inch of soil to cover them. Keep the pot indoors or in a cool place until the germination process has not started yet. Since the germination process likes to take its time, it is best to plant the seeds about three months before the warm weather arrives. That way, you can make full use of the sun, which rosemary is very partial to.

Step 2: Wait for two weeks or up to a month for your seeds to sprout. Rosemary seed germination normally takes longer than some herbs like mint and basil. Once they grew a few inches tall, move the pot to a well-lit area in your house. As was already mentioned, rosemary loves sunlight.

Step 3: Water your rosemary once a week. You shouldn’t water them frequently because they are sensitive to drainage. It’s best done by just keeping the soil moist. Clay-based soil is not suitable for rosemary because it does provide excellent drainage. Most of the time, you don’t even have to pour water on the plant. Spraying is most often enough. Some gardeners even go as far as watering their rosemary plants only when the soil it is in dries out.
