From our point of view as rosemary plants, yes, you can absolutely grow us from seed. However, we must be forthright: it is one of the most challenging ways to begin your journey with our kind. Our seeds possess a naturally low germination rate. This is not a flaw but a survival trait; in our native Mediterranean habitats, conditions must be perfect for a seedling to have a fighting chance against the dry, rocky soil and intense sun. We do not expend energy frivolously. Therefore, even under ideal circumstances, do not expect every single seed you sow to sprout. Patience is not just a virtue here; it is an absolute requirement.
To coax us from our dormant state, you must recreate the gentle, consistent conditions we crave. We are not a seed that tolerates being buried deeply. A light covering of a fine, well-draining seed-starting mix is all we need, as we require some light to trigger germination. The medium must be kept consistently moist but never waterlogged, as our tiny emerging roots are extremely susceptible to rot. The most critical factor is warmth. Our seeds will remain dormant in cool soil. A steady temperature between 70-80°F (21-27°C) is ideal, often requiring a heat mat to maintain. This warmth tells us that the harsh conditions have passed and it is safe to emerge.
If you provide the right environment, you may see the first signs of life—tiny green sprouts—in two to four weeks, though it can sometimes take much longer. This is where the real test begins. We are notoriously slow growers in our youth. Our initial focus is not on producing fragrant foliage for you but on establishing a strong, robust root system. This foundational work is what will make us a resilient plant later. We demand bright, direct light immediately upon sprouting; without it, we will become leggy, weak, and struggle to survive. Keep the soil lightly moist and ensure excellent air circulation to prevent "damping off," a fungal condition that swiftly claims young seedlings.
Once we have established several sets of true leaves and outgrown our initial container, we are ready for transplanting. We insist on a home that mimics our native environment: extremely well-draining, gritty or sandy soil, and a pot with excellent drainage holes. We despise having "wet feet." As we mature, our needs shift. We thrive in full, blazing sun and prefer to dry out thoroughly between waterings. The growth you witnessed as a painstakingly slow seedling will gradually accelerate. While growing us from seed requires significant time and attention, the resulting plant is often exceptionally hardy and well-adapted to your specific care routine from its very first days.
