How to care for your Penstemon Heavenly Blue

• Planting: Prefers well-draining soil and full sun to partial shade. Plant the seedlings in the spring or early summer, ensuring that they have enough space to grow.
• Watering: Keep the soil evenly moist, but not waterlogged. Water the plant deeply once a week, especially during hot and dry periods. However, be careful not to overwater, as this can lead to root rot.
• Fertilising: Does not require a lot of fertiliser. Apply a light application of a balanced fertiliser in the Spring to encourage healthy growth and blooming.
• Pruning: After the blooming season ends, prune the plant back to a few inches above the ground to encourage new growth in the Spring. Deadheading spent flowers as they fade can also encourage additional blooming.
• Mulching: Mulch around the base of the plant in the Autumn to protect the roots from freezing temperatures and to retain moisture.

By following these care tips, you can enjoy a healthy and vibrant Penstemon Heavenly Blue in your garden for years to come.
