Bethlehem sage in September: monthly care

Pulmonaria saccharata thrives in partial to full shade, making it ideal for woodland gardens, shady borders, or beneath deciduous trees and shrubs. It tolerates a range of soils but performs best in moisture-retentive loam or clay that doesn't dry out completely in summer. Avoid hot, dry positions where the foliage will scorch and wilt. Plant in March, April, September, or October when the soil is workable and temperatures are moderate. Autumn planting is often preferable as it allows roots to establish before winter, but spring planting works well if you water attentively through the first summer. Space plants 40 cm apart to allow for their eventual spread of 40–60 cm; they will gradually form attractive clumps. Prepare the planting area by digging in plenty of organic matter—garden compost or well-rotted manure—to improve moisture retention and soil structure, especially if your soil is light or sandy. Dig a hole slightly larger than the root ball, set the plant at the same depth it was growing in its pot, and firm the soil gently around the roots to eliminate air pockets. Water thoroughly after planting to settle the soil and encourage root contact. Apply a 5 cm layer of mulch around the base—leaf mould, composted bark, or garden compost—to conserve moisture and suppress weeds. Keep the mulch clear of the crown to prevent rot. Water regularly during the first growing season until the plant is established, particularly if rainfall is scarce. Pulmonaria is evergreen, so the foliage remains visible year-round once settled in.
