How to Grow Rosemary Indoors

Rosemary is an aromatic and flavorful herb that can be easily grown indoors. It’s a hardy plant that can be used in a variety of dishes and is known for its medicinal properties. In this article, we’ll walk you through how to grow rosemary indoors and ensure that your plant thrives. 

Steps to Grow Rosemary

Choose the Right Pot

The first step in growing rosemary indoors is choosing the right pot. Rosemary prefers well-draining soil, so you’ll want a pot with a drainage hole in the bottom. A pot that is 8–10 inches in diameter is ideal for growing one rosemary plant. If you’re planning on growing multiple plants, choose a larger pot to accommodate their roots. 

Add Quality Soil 

Rosemary prefers soil that is slightly alkaline, with a pH of 7.0 or higher. Use a high-quality potting soil that is designed for herbs and vegetables, as it will provide the right balance of nutrients and drainage. You can also add perlite or sand to the soil to increase drainage and prevent the soil from becoming waterlogged. 

Planting Your Rosemary 

Once you have your pot and soil ready, it’s time to plant your rosemary. Fill the pot with soil, leaving about an inch of space at the top. Make a small hole in the center of the soil, and gently remove your rosemary plant from its container. Place the root ball in the hole, and fill in the soil around it, pressing it down gently. 

Watering Your Rosemary 

Rosemary prefers dry soil, so you should only water your plant when the soil is dry to the touch. Be sure not to overwater, as this can lead to root rot. When you do water, do so thoroughly, ensuring that the water runs out of the drainage hole in the bottom of the pot. 

Lighting Requirements 

Rosemary requires plenty of sunlight to grow, so you should place your pot in a sunny window that receives at least six hours of sunlight a day. If you don’t have a window that receives this much light, you can use artificial lighting to supplement. LED grow lights are a good option, as they produce less heat than other types of grow lights. 

Temperature and Humidity 

Rosemary prefers temperatures between 60–75 degrees Fahrenheit, so keep your plant away from drafty areas or areas with extreme temperature fluctuations. It also prefers low humidity, so avoid placing your plant in a room with high humidity, such as a bathroom or laundry room. 

Pruning Your Rosemary 

Pruning is an important step in growing rosemary. It not only helps keep your plant healthy, but it also encourages new growth. Prune your rosemary by snipping off the top 1/3 of the stem. This will encourage new growth from the base of the plant. 

Harvesting Your Rosemary 

Once your plant has reached a height of 6–8 inches, you can start harvesting your rosemary. Use a pair of scissors or pruning shears to snip off the stem just above a set of leaves. This will encourage new growth and ensure that your plant continues to produce. You can use fresh rosemary in a variety of dishes, or you can dry it for later use. 

Pests and Diseases 

Rosemary is generally a hardy plant that is not susceptible to many pests or diseases. However, it can be susceptible to spider mites or whiteflies. If you notice small webs or whiteflies on your plant, you can try using a spray of water to dislodge them. You can also use an insecticidal soap to kill them. Be sure to follow the instructions on the label carefully. 


Growing rosemary indoors is a great way to enjoy fresh herbs all year round. By choosing the right pot, providing quality soil, planting correctly, watering properly, ensuring adequate lighting, maintaining appropriate temperature and humidity, pruning regularly, and harvesting correctly, you can ensure that your rosemary plant thrives indoors. With a little bit of care and attention, you’ll be able to enjoy the delicious aroma and flavor of fresh rosemary in your favorite dishes.
