Rosemary Plant Propagation

Rosemary bushes are started from seed. The seed is hard to start. Soak Rosemary seeds in water a few hours before planting. We recommend starting them indoors, as they take a long time to sprout. Start seed indoors six weeks before the last frost.

Note: For indoor starts, we recommend using a heated germination mat, to increase the speed of germination. And, it, results in a higher germination rate.

If you want to grow and enjoy them as houseplants, start them indoors even earlier. After they sprout, place them in a warm, sunny window.

When transplanting outdoors, space plants three feet or more apart. In warm areas where there is no frost or freezes, pick a place where the plant can grow for many years.

Final Plant Spacing:  2 to 3 feet apart.

Days to Germination: 15 – 25 days.

How to Grow Rosemary Plants

Growing Rosemary plants is very easy. They prefer full sun to partial shade. They will do well in almost any soil. The plants tolerate dry soil conditions and drought. They should not require water during droughts, but add water if they appear to wilt. They usually do not require fertilizer, except for container-grown plants.

Once your Rosemary shrub reaches a couple of feet, don’t hesitate to bring out the shears and shape them. Be creative if you dare!

Harvest leaves and use fresh, as needed, in the summer. As autumn arrives, harvest leaves in the morning, when the oils are at their peak. Spread leaves out to dry in a cool, well-ventilated area. Or, pick and freeze immediately.

If you are growing Rosemary in containers, you can over-winter plants in a greenhouse in some areas.

Ideal pH: 6.5 – 7.5
