watering
Lungwort should be watered regularly, preferably on a weekly basis. The soil should remain evenly moist, so it’s best to check the soil periodically to ensure it doesn’t dry out. During warmer months, it may be necessary to water more often, allowing only the top layer of soil to dry before watering again. Lungwort does not like wet feet, so take care not to over-water. In cooler months, watering may need to be reduced as the plant goes dormant.
sunlight
Lungwort (Pulmonaria 'Roy Davidson') requires partial sunlight to do well. This means that it should get around 4 to 6 hours of direct, unfiltered sunlight per day. If you are growing your Pulmonaria in a shady area, it can tolerate more sun if you provide afternoon shade or if you keep the soil consistently moist. The best time of day for sun exposure for lungwort is late morning to early afternoon when the sun is brightest ,ideally between 10am to 2pm. In warmer climates, where the sun is especially hot, Pulmonaria needs more protection since too much sun can cause damage.
pruning
Lungwort (Pulmonaria 'Roy Davidson') should be pruned in late winter or early spring, before new growth begins. This helps ensure that plants look their best and encourages healthy new growth. It is best to start with light pruning, removing dead and unruly growth. Once this is done, you can decide if more drastic pruning is necessary to manage the size and shape of your plant. If the plant is too tall, prune the branch tips, or cut the plant back by up to 1-third of its total height. If the plant is spreading away from the desired area, prune away the branches that are too far out to your target area. Finally, remove any leaves that appear shriveled or discolored. After pruning, be sure to give your lungwort plenty of water and sun for the remainder of the growing season.
