Frequently Asked Questions

What pest or disease commonly affects Salvia rosmarinus (creeping rosemary) and how can I treat it?

Watch for powdery mildew, which shows up as a white, dusty coating on leaves in humid, poorly ventilated conditions. Improve airflow by spacing creeping rosemary so plants don’t knit tightly, water at the base in the morning, and remove the most affected tips. If it keeps worsening, treat with a horticultural fungicide labeled for powdery mildew on edible herbs and repeat per label directions.

How often should I water creeping rosemary (Salvia rosmarinus) during active growth?

Water deeply only when the top 1–2 inches of soil have dried, then let excess drain—creeping rosemary prefers evenly dry conditions rather than constant moisture. In warm months this often means about once every 7–10 days, but always adjust to your soil and rainfall. Avoid wet, heavy soil because it promotes root rot and leaf decline.

How can I tell when Salvia rosmarinus is ready to harvest?

Start harvesting once plants are well established and have plenty of flexible, strongly aromatic shoots—typically around the 90-day window. For the best flavor, pick in the morning and harvest young to mid-length stems (not the woody base), taking no more than about one-third of the plant at a time. If stems snap easily and the leaves are dense and fragrant, they’re ready; if growth is slow and leaves look dull, wait a bit longer.

Breathe in the resinous, pine-bright fragrance that spills from Prostrata’s low, creeping mats—an aromatic evergreen that feels alive underfoot. Its narrow needles are deep green and softly textured, releasing a vivid herbal character with every brush, making it a standout for fresh garden presence and long-lasting scent. Grow Prostrata for fragrant groundcover that shines in borders and containers, and for aromatic sprigs that elevate herb-forward preparations and infusions with its distinctive, concentrated rosemary note.

Sowing Tips

Transplant Conditions

Wait until soil reaches 60°F and nights stay above 40°F before moving outdoors. Harden off for 7 days first.

Expert Note

For fastest establishment, use rooted cuttings or nursery starts and plant in well-drained soil after nights are consistently mild, since rosemary dislikes cold, wet roots.
