Salvia × sylvestris 'Blauhügel' problems — and how to fix them
Salvia × sylvestris 'Blauhügel' (Salvia × sylvestris 'Blauhügel') 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.
Sprawling habit
Caused by shade or rich soil. Plant in full sun on lean ground and shear lightly to keep the mound tight.
Powdery mildew
Grey-white film on leaves in humid, crowded plantings. Improve airflow, water at the base, and remove affected foliage.
Crown rot in wet soil
Poor winter drainage rots the base. Grow in sharply drained soil and keep mulch clear of the crown.
Short bloom window
Without deadheading the flush is brief. Cut spent spikes back by a third to encourage repeat flowering through summer.
