Frequently Asked Questions

What pest or disease commonly affects Salvia pratensis (Rhapsody In Blue), and how can I control it?

Salvia pratensis commonly develops powdery mildew in warm, humid weather. Improve airflow by spacing plants about 18–24 in. apart and watering at the base (not overhead), then remove any badly spotted leaves early and treat with a labeled sulfur or potassium bicarbonate product if mildew is spreading.

How do I know when Rhapsody In Blue (Salvia pratensis) is ready to harvest?

Harvest cut flowers when the first flower buds on a spike are just starting to open, with most buds still closed. For seed (if you’re collecting), wait until the flower spikes have fully dried and the tiny seeds release easily from the mature calyxes, typically around 70 days after sowing depending on conditions.
