Planting May Night Salvias
When planting May Night Salvias, it’s essential to choose a location that receives full sun to partial shade. The soil should be well-draining and rich in organic matter, with a pH between 6.0 and 7.0. Plant the salvias in the spring or fall, spacing them 12-18 inches apart. Water the plants regularly during the first growing season, but avoid overwatering, which can lead to root rot. It’s also important to deadhead the flowers regularly to encourage more blooms and prevent the plant from going to seed.
May Night Salvias can be grown in a variety of soil types, including clay, loam, and sand. However, they prefer well-draining soil that is rich in organic matter. Adding compost or well-rotted manure to the soil can help improve its fertility and drainage. Soil pH is also an essential factor to consider when growing May Night Salvias. A pH between 6.0 and 7.0 is ideal, but the plants can tolerate a slightly wider pH range.

If the plants do become infected, treat them with a fungicide and remove any infected foliage.
Bloom Secrets
May Night Salvias are known for their vibrant purple-blue flowers, which bloom in the late spring and early summer. To encourage blooming, provide the plants with full sun to partial shade and fertilize them regularly. Deadheading the flowers can also help encourage more blooms and prevent the plant from going to seed. May Night Salvias can be forced to bloom indoors by providing them with a period of cold temperatures and then moving them to a warm location with plenty of light.
Forcing Blooms Indoors

To force blooms indoors, plant the salvias in a pot in the fall and place them in a cold frame or unheated garage. Keep the soil moist but not waterlogged, and provide the plants with minimal light. After 6-8 weeks, move the plants to a warm location with plenty of light, such as a sunny windowsill or under grow lights. Water the plants regularly and fertilize them with a balanced fertilizer.
