Salvia can be a relatively easy plant to grow from seed, especially if you follow a few key steps. Whether you choose to sow the seeds indoors or directly in your garden, there are a few factors to consider to ensure successful germination and growth.
If you decide to start salvia seeds indoors, it is best to sow them about 10-12 weeks before the last expected frost in your area. This will give the plants ample time to grow and establish themselves before being transplanted outside. To start, fill a seed tray or small pots with a seed starting mix or a well-draining potting soil.
When sowing the seeds, it is important to do so thinly and evenly. This will prevent overcrowding and allow each plant to receive adequate sunlight and nutrients as they grow. Gently press the seeds into the soil, ensuring they are in good contact with the growing medium, but avoid burying them too deeply.
After sowing the seeds, lightly mist the soil with water to ensure it is evenly moist. It is important to keep the soil consistently moist throughout the germination process, so be sure to check the moisture levels regularly. You can cover the tray or pots with a plastic dome or wrap them in plastic wrap to create a mini greenhouse effect, which will help retain moisture and create a warmer environment for germination.
Place the tray or pots in a warm location, ideally between 70-75°F (21-24°C). This will encourage faster and more successful germination. Once the seeds have germinated, remove the plastic covering and place the seedlings in a bright location, such as a sunny windowsill or under grow lights.
As the seedlings grow, it is important to provide them with proper care and attention. This includes regular watering to keep the soil evenly moist, but not overly saturated. Avoid overwatering, as this can lead to root rot and other issues. Additionally, it is important to provide the seedlings with adequate light, either by placing them in a sunny location or using grow lights.
When the threat of frost has passed and the seedlings have developed a strong root system and several sets of true leaves, they can be transplanted outdoors. Choose a sunny location with well-draining soil for your salvia plants. Dig a hole slightly larger than the root ball of the seedling and gently place it in the hole. Backfill with soil, firming it gently around the base of the plant. Water thoroughly after transplanting to help settle the soil and ensure good root-to-soil contact.
If you prefer, you can also directly sow salvia seeds in your garden. Wait until after the last frost in your area and choose a location that receives full sun and has well-draining soil. Prepare the soil by removing any weeds or debris and loosening it with a garden fork or tiller. Sow the seeds thinly and evenly, following the same guidelines as indoor sowing, and lightly cover them with a thin layer of soil. Keep the soil consistently moist until the seeds germinate.
While growing salvia from seed does require some care and attention, it can be a rewarding experience. By following the proper steps for indoor or direct sowing, providing adequate light and water, and choosing a suitable location for transplanting, you can successfully grow salvia from seed and enjoy its beautiful blooms in your garden.
