One of the easiest ways to grow rosemary plant indoors is to grow them in containers. If your rosemary plant is in containers, you have to start acclimating the plant to the diminished light it will receive when it is bring indoors. This plant really requires full sun and even the brightest window is not the same as a sunny garden. If there is time you can start to acclimate the rosemary plant by moving it to a shadier part of the garden for part of the day. The longer you are able to do this, the better suited the rosemary plant will be to the indoor surroundings.
Growing Rosemary Plant Indoors
Light Requirement: Place the rosemary plant in the brightest window that you have. If the rosemary plant starts to struggle due to lack of light you can add a florescent light to the mix.
Humidity Requirement: Powdery mildew is really a challenge for rosemary plant whether it is grown indoors or outside. To actually reduce the likelihood of mildew on the plant use a fan to create a breeze for a few hours a day. The less humidity the rosemary plant is exposed to the better.
Water Requirement: This plant does not really like wet feet AKA wet roots. Once the top inch of the soil is dry make sure you water the plant. During the winter period the rosemary plant will naturally start to slow its growing process and it will require less water.
Rosemary Cuttings: If you don’t actually have a potted rosemary plant, or you don’t have rosemary plant in your garden, you can simply take a cutting with the permission from a friend’s rosemary plant.
Furthermore, the best time to take cuttings from rosemary plant is in the spring when the plant is vigorously growing. On the other hand fall cuttings will work too. Make sure you take the cutting with clean pruners from the youngest, healthiest looking branch. It should be at least four inches long measuring from the tip towards the plant. You have to remove the bottom leaves with the pruners, don’t rip or pull off the leaves from the plant. Make sure you dip the end in rooting hormone powder and place it in bright light in a jar of water. Only the part of the rosemary plant stem that has been cleared of leaves should be in the water. Ensure you refresh the water every few days.
Once the roots emerge you can plant them in fresh potting soil amended with sand, vermiculite or perlite for optimal air and water circulation. This plant does best in loose, well-draining soil. You can plant the rosemary directly to its permanent container or use smaller containers until the rosemary plant has established a solid root base. You can consider using a permanent, decorative container that is at least 6 inches deep with adequate drainage.
