Rosemary is a wonderful herb that is popular as both a garden herb and a culinary favourite.
Soil Conditions: Rosemary does best with compost-rich, well-draining soil.
pH: 6 to 7.
Sunlight: Plant Rosmarinus officinalis in full sun. When potted, it will tolerate partial shade better than soil-planted rosemary.
Water Requirements: Rosemary does best when the top few inches of soil is allowed to dry out slightly. Container plants should be watered from the bottom, by placing pots (or starts) in a shallow tray. Water just enough for container plants to take up the moisture within an hour.
Rosemary prefers a bit of humidity, so it does well near grassy or well-mulched areas as long as it isn’t being overwatered.
Mulching: Don’t allow mulch to pile up against the base of your rosemary plants.
Companions: Brassicas and beans do very well near rosemary, which is believed to fend off cabbage moths, cabbage flies, and bean beetles. Rosemary isn’t recommended as a neighbor for carrots, pumpkins, or potatoes.
- Choose a container. You can use small pots or egg cartons, but your best choice is to purchase a seed-starting tray with a plastic humidity dome.
- Prepare a seed-starting mix. Ensure that the soil you use has good drainage. You can create your own mix with equal parts perlite and peat moss or purchase a sterile, soilless seed-starting mix. Lightly moisten the mix before adding it to your container.
- Add the rosemary seeds. Sprinkle three to four seeds on top of the seed-starting mix. Cover the seeds with a small amount of mix, but not so much that they don’t get sunlight.
- Lightly water, then cover the container. Mist the rosemary seeds with water using a spray bottle, making sure the surface is moist but not sopping wet. This helps settle the seeds into the mix. Cover the container with the plastic dome or plastic wrap.
- Store in a sunny, warm location until germination. Place the seed-starting tray somewhere that receives plenty of direct sunlight. A heat mat and an indoor full-spectrum light can be used if you’re unable to find a warm, sunny area. If the surface of the seed-starting mix appears dry, remove the plastic cover and lightly mist with water until moist. The germination process typically takes two to four weeks.
- Once seedlings appear, remove the plastic cover. When the rosemary seedlings emerge from the soil, place the seed-starting tray in a shallow water tray. Water will seep up into the soil through the container’s drainage holes. Keep the seedlings in direct light.
- Transplant the seedlings. Once seedlings are 7-12cm tall, transplant them outdoors. Plant rosemary seedlings in compost-rich soil with good drainage. Choose a location where they receive six to eight hours of direct sunlight each day.
