How to Start Rosemary Seeds

1. Start Indoors
To begin your rosemary seed growing journey, it’s best to start indoors, especially if you live in a region with cold winters. Consider using containers that can be brought indoors when temperatures drop. Rosemary thrives in warmer climates, so starting indoors is beneficial. Denise Pizzini recommends starting rosemary seeds in open flats at least 10-12 weeks before planting outside, after the danger of frost has passed.

2. Place Seeds Evenly
Using a quality germination mix and a tray with drainage holes, ensure the soil is moist but not soggy. Press the seeds into place evenly without poking deep holes. Rosemary seeds require light to germinate, so cover them lightly with soil or not at all. Mist the seeds to help them make better contact with the soil and wait for germination to occur within 14-21 days.

Transplanting Rosemary Outdoors

Once your rosemary seeds have sprouted into seedlings, it’s time to transplant them outdoors.

1. Wait for Four True Leaves
Ensure your seedlings have at least four true leaves before transplanting them into pots. While you can attempt to grow rosemary indoors, mature plants thrive best outdoors. Container-grown rosemary can do well in a sunny window as long as the soil is kept evenly moist.

5 Essential Tips for Growing Rosemary from Seed

1. Give your rosemary lots of light: Rosemary thrives in full sunlight, so ensure it receives ample light for optimal growth.
2. Feed and water accordingly: Provide your rosemary plant with regular watering and a balanced fertilizer to promote healthy growth.
3. Use the right soil: Rosemary prefers well-draining soil, so opt for a sandy or loamy mix to prevent root rot.
4. Mimic Mother Nature: Try to replicate the Mediterranean climate for your rosemary plant by providing warmth and adequate moisture.
5. Mist or bottom water: Avoid watering the foliage and instead water from the base of the plant to prevent issues like powdery mildew.

Maintenance Tips for Your Rosemary Plant

Growing rosemary from seed requires patience and care, but the rewards are worth it. Here are some maintenance tips to keep your rosemary plant thriving:

Plant three to four seeds per hole to increase germination chances.
In warm climates, rosemary should come back every year. In colder regions, consider bringing container-grown rosemary indoors for the winter season.

With these tips and expert advice, you can successfully grow rosemary from seed and enjoy a bountiful harvest of this versatile herb in your garden.
