Frequently Asked Questions

Why is Rosemary (Salvia rosmarinus) described as slow to germinate?
Rosemary seeds possess naturally low germination rates and can take 14 to 28 days to sprout due to internal germination inhibitors. Sowing the seeds shallowly and keeping the medium consistently warm is critical.
What is the optimal temperature for Rosemary seed germination?
Rosemary seeds germinate best at warm room temperatures between 21 and 26 degrees Celsius (70 to 79 degrees Fahrenheit).
How deep should Rosemary seeds be planted?
Sow the seeds very shallowly, approximately 1.5875 to 3.175 millimeters (1/16 to 1/8 inch) deep, or press them gently onto the surface of the Premium Nutrient-Rich Potting Soil and cover with a very thin layer of soil.
What USDA Hardiness Zones are suitable for planting Rosemary outdoors?
Rosemary is a woody perennial hardy in USDA Zones 7 through 11. In colder northern zones (Zones 1 through 6), it must be grown in containers and moved indoors before winter freezing occurs.
Can I grow Rosemary indoors year-round?
Yes. Rosemary is an excellent container plant that can be grown indoors.
Why does this kit use Premium Nutrient-Rich Potting Soil instead of compressed coir discs?
Rosemary roots are highly sensitive to standing water and can rot quickly in dense, water-retaining coir fiber plugs. Our Premium Nutrient-Rich Potting Soil is formulated with sand and perlite to provide the sharp, rapid drainage this Mediterranean herb requires.
