Frequently Asked Questions

What pest or disease most often affects Salvia rosmarinus (rosemary) and how can I control it?

Rosemary commonly suffers from root rot and stem dieback when soil stays wet—watch for wilting plus blackened, mushy stems near the base. Improve drainage immediately (loosen soil and avoid overhead watering), then let the soil dry slightly between waterings; remove and discard any badly blackened stems to reduce spread. If you see gray, dusty growth or leaf spotting, thin for airflow and treat early with an appropriate fungicide labeled for herbs.

How often should I water Salvia rosmarinus during its main growing phase?

During active growth (late spring through summer), water deeply only when the top 1–2 inches of soil are dry; in full sun, this is often about once every 7–14 days depending on heat and soil. Aim for even moisture without sogginess—rosemary prefers a dry-to-moist cycle rather than constantly wet soil. In containers, ensure excess water drains freely and never leave the pot standing in a saucer of water.
