Lungwort 'Bertram Anderson' problems — and how to fix them
Lungwort 'Bertram Anderson' (Pulmonaria longifolia) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Less prone than some pulmonarias, but can still appear in warm, dry conditions; cut back after flowering and water well.
Slug damage
Emerging spring foliage is vulnerable; apply controls early in the season.
Summer dormancy
Extended drought may trigger premature dormancy; maintain soil moisture to keep leaves looking good through summer.
Leaf scorch
Direct sun in warm spells causes bleaching; ensure adequate shade cover.
Crown rot
Excessive soil moisture combined with poor drainage can rot the crown; improve drainage if plants decline rapidly.
