Salvia nemorosa 'Blue Marvel'
-
Light: Prefers full sun, which encourages the most robust flowering. It can tolerate light shade, but flowering may be reduced in lower light conditions.
-
Water: Regular watering is needed, especially during dry spells, but it prefers well-draining soil and should not sit in water. Allow the top inch of soil to dry out between waterings.
-
Humidity: Prefers moderate to low humidity. It performs well in dry to average humidity environments and does not tolerate overly wet conditions.
-
Temperature: Hardy in USDA zones 4-8. 'Blue Marvel' thrives in cooler to moderate temperatures and is tolerant of heat but may need some protection from extreme heat in hotter climates.
-
Soil: Prefers well-draining, slightly alkaline soil. Sandy or loamy soil works best, but it can adapt to a variety of soil types as long as they drain well.
-
Fertilizer: Apply a balanced, slow-release fertilizer in spring to promote healthy growth and flowering. Avoid over-fertilizing, which can encourage too much foliage growth at the expense of blooms.
-
Pruning: Deadhead spent flowers to encourage continued blooming throughout the season. After flowering, cut back the plant to maintain its shape and encourage fresh growth.
