Prolonged exposure to the Lungwort plant is bad as it can cause wilting of its leaves and could also scorch them.
Watering Your Lungworts

You can achieve this by letting the topmost part of the soil dry a little before the next watering session. Make use of a moisture meter to help check the soil’s moisture level.
Keep watering once or twice a week during the hot periods. During the winter season, limit watering the plant to once a month.
