PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Salvia nemorosa ‘Midnight Purple’ in spring as the soil begins to warm. This gives the plant ample time to establish strong roots before the blooming season.
Autumn: Planting in early autumn is also suitable, allowing roots to develop before winter, leading to stronger growth the following year.
Site Selection
Sunlight: Salvia performs best in full sun. Choose a site that receives a minimum of 6 hours of sunlight daily to ensure dense flowering and healthy foliage.
Soil: Plant in well-drained soil. While tolerant of a range of soils, Salvia nemorosa ‘Midnight Purple’ thrives in moderately fertile conditions. Improve heavy soils with organic matter like compost or grit to aid drainage.
Planting Instructions
Digging the Hole: Create a hole twice the width and equal in depth to the plant’s root ball.
Soil Improvement: Mix in compost or well-rotted manure to enrich the soil and improve texture.
Planting: Place the plant at the same depth as it was in its pot. Backfill with soil, firming gently to remove air pockets.
Initial Watering: Water thoroughly after planting to help the roots settle and begin growing into the surrounding soil.
Watering
Active Growth: Water Salvia nemorosa ‘Midnight Purple’ regularly during dry spells in the growing season. Let the soil dry slightly between waterings to avoid root rot.
Dormancy: Reduce watering significantly during autumn and winter when the plant is dormant.
Feeding
Early Season: Apply a balanced, slow-release fertiliser in early spring to support lush growth and plentiful flowers.
Mid-Season: A light feed after the first flowering flush can encourage a second bloom later in the season.
Pruning
Deadheading: Regularly remove faded flower spikes to prolong blooming and maintain the plant’s neat form.
End-of-Season Pruning: Cut back Salvia nemorosa ‘Midnight Purple’ to just above ground level in autumn once flowering ends, encouraging vigorous regrowth the following spring.
Mulching
Spring Mulch: Apply mulch in spring to retain soil moisture, suppress weeds, and regulate soil temperature.
Winter Protection: In colder months, mulch around the base to protect roots and crowns from frost damage.
