HOMESTEAD HOW-TO
Since there are four types of rosemary, you want to choose the one that is best for you.
It’s best to start rosemary seeds indoors 10 to 12 weeks before the last frost date in your area – or before you plan to move them outdoors into a container or the garden.
Fill seed starting trays or a small pot with the seed starting mix, leaving about half an inch from the top.
Make small tiny holes in the soil and place the tiny rosemary seeds in the soil. Lightly brush the soil over the seeds.
You need to make sure that the seedlings receive sufficient light to prevent weak, stretched stems.
Keep the soil consistently moist but not waterlogged by misting it regularly (a couple times a day will do).
