How to Grow Rosemary in Winter
- 1). Place large gravel in the bottom of your container. Rosemary needs soil that drains well, so using gravel keeps the soil from clogging up the drainage holes in the pot. Fill the pot with a vegetable potting soil.
- 2). Plant a rosemary plant in the soil. Put it at the same depth as it is in its current pot. Rosemary is very hard to grow from seed, so it's best to start with a plant. Then from that plant you can use clippings to grow more plants.
- 3). Keep the plant damp for a few days and then water only when the soil gets dry. Use a compost tea around the plant on the soil once a month to keep nutrients in the soil. Compost tea is liquid and will get into the soil faster with less harshness. Just soak your ready-to-use compost in some water for a day, then pour off the water into a watering can and use it around your plant. The nutrients from the compost will be in the water.
- 4). Keep your plant in a place that gets 6 to 8 hours of sun each day. Next to a large window that has no covering most of the day is a good place.
- 5). Rosemary likes good air circulation. When indoors it normally does not get enough and tends to grow a powdery mold. Place a small electric fan in the area near the plant to circulate the air and it should be fine.
- 6). Once the weather gets warmer and there are no more threats of frost, you can place the container outside in a sunny area. It will do better outdoors, so leave it there until the next winter approaches.
