How to grow rosemary indoors

Growing it

When temperatures drop into the 30s outdoors, it’s time to bring your rosemary indoors. First, the bad news: Rosemary can be a little tricky to grow indoors. But growing rosemary indoors in winter is certainly possible with the right gardening conditions. For best results, give these plants plenty of sunlight. This sun-loving herb likes a window with southern exposure, and at least 4 hours of direct sunlight. If you don’t have a south, west or southwest facing window, you may need to provide supplemental light. Rotate your plant weekly so the rosemary gets sunlight on all sides.

Overwatering rosemary is a great way to kill this plant. Water this drought-tolerant plant when the first inch of soil is dry. Make sure your container has excellent drainage too; this helps prevent root rot. Prune rosemary stems to maintain the plant's shape, and enjoy the leaves in your meals. Any dead or brown branches should be pruned away as soon as possible.

Propagate it

It’s not easy to grow rosemary from seed, but you can also find small transplants at nurseries. Rosemary is easy to propagate, and plants are often started from cuttings.

  • Clip a couple inches of new growth off an established rosemary plant.
  • Carefully snip away the bottom leaves, and dip the bottom stem into a hormone rooting powder.
  • Plant the cuttings in small containers with peat moss and perlite.
  • Lightly mist the cuttings, and the plants will start rooting.

Challenges

Powdery mildew is a white coating on the leaves, which sometimes appears on rosemary plants grown indoors. Some experts recommend you run a small fan near the plant for a couple hours a day to increase the air circulation in the room. And be sure to keep rosemary plants away from heater drafts.

Spider mites can cause white dots and webbing on rosemary plants. Give your rosemary periodic showers to help control the pests.
