How to Grow Blue Salvia in Your Garden?

Growing blue salvia in your garden is a rewarding experience, thanks to its low-maintenance nature and stunning blooms. Here’s a step-by-step guide:

  1. Choose the Right Location: Blue salvia thrives in full sun but can tolerate partial shade. Ensure the planting site receives at least 6 hours of direct sunlight daily.
  2. Prepare the Soil: While the plant can grow in poor soil, it prefers well-draining soil with a pH between 6.0 and 7.5.
  3. Planting: Sow blue salvia seeds directly into the soil or start them indoors 6–8 weeks before the last frost. Space the plants 12–18 inches apart to allow for proper air circulation.
  4. Watering: Water the plant regularly during its initial growth period. Once established, blue salvia is drought-tolerant and requires less frequent watering.
  5. Fertilizing: Apply a balanced fertilizer once a month during the growing season to encourage vigorous growth and blooming.
  6. Pruning: Deadhead spent flowers to promote continuous blooming and prevent self-seeding.

By following these steps, you can enjoy a lush, vibrant display of blue salvia in your garden year after year.
