Rosemary seeds are tricky to germinate and grow into adulthood. However, propagating rosemary from seed is a rewarding process that connects you to your plant in a way which cannot be matched by a nursery grown seedling. Purchase your rosemary seeds from a reliable nursery that has a large selection of seeds in stock.
When to Plant Rosemary seeds can take a while to germinate so start them very early, about three months before warm weather arrives in your area. Do not expect a high germination rate of all of the rosemary seeds you plant, because rosemary naturally has a much lower germination rate when compared to say, basil. How to Plant
Most nurseries grow rosemary from cuttings, not seeds. Germination is notoriously low, so plant more seeds than you plan to grow on. Sow them barely covered with sterilized seed starting mix over bottom heat. Once germinated, rosemary is highly prone to damping off, so keep watering to a minimum, provide bright light, and ventilation.
You can learn how to grow rosemary in a few minutes. Rosemary is commonly used in the kitchen as a flavoring. The spicy, aromatic leaves can be used fresh or dried in many dishes flavoring beef, veal, pork, lamb, stuffings, soups, sauces, and salad dressings.
Pruning rosemary is the best way to ensure bushier plant growth with the desired shape, size, and flavor. Do this every year when you see some active growth at the beginning of the growing season, i.e., early spring or mid-spring.
Set out rosemary in spring, planting starter plants 2 to 3 feet apart; you can also plant in fall in zone 8 and south.
