pulmonaria

Pulmonaria should be watered thoroughly whenever the top 1-2 inches of soil feels dry. This usually means every 1-2 weeks or so depending on light, temperature, humidity, soil type, and size of the plant. Water should be directed at the soil to minimize the chance of getting water on the foliage and flowers to reduce the chance of fungal problems. Once established, the plant can be left to dry out more between waterings, but never allow the plant to dry out completely. Watering in the morning is preferable to watering in the evening.

Pulmonaria rubra, commonly known as red lungwort, is a woodland perennial that prefers partial shade. In spring, the plant benefits from having between 4 and 6 hours of direct sunlight daily. As the growing season progresses and the days become longer, the hours of direct sun can safely be increased. During summer, 6 to 8 hours of direct sun per day is ideal. Once autumn arrives, the hours of direct sun should be decreased and never exceed 5 hours daily. When the winter solstice occurs, the plant will be best suited with just 2 or 3 hours of direct sunlight daily.

Pulmonaria rubra is best pruned in early spring, before new growth begins. Pruning should be relatively light in order to keep the plant looking natural. Remove any dead flower stalks left over from the previous season by clipping them off at the base. Additionally, thin out the tips of any overly-long and leggy stems that reach up and out of the clump. This will improve air circulation and prevent fungal diseases. Remove any yellowing or wilting leaves, which could indicate disease. Finally, you can deadhead any remaining flowers to promote another flush of blooms if desired.
