Start the season right
Plant lungwort in full sun.
Match the soil
Pull a soil test from your local Extension lab to confirm pH and drainage match lungwort's needs before planting.
Water steadily
Keep the root zone evenly moist through establishment. Match watering to the plant's drainage preference and your local rainfall.
Harvest at its peak
Cut lungwort blooms in the cool of the morning, just as they open, for the longest display.
