Understanding Rosemary’s Needs
Rosemary (Salvia rosmarinus) is a hardy, drought-tolerant shrub that prefers sunny conditions and well-drained soil. While it’s native to the Mediterranean region, it can adapt well to Colorado’s unique environment, especially when given the right care.
Choosing the Right Rosemary Variety
The first step in growing rosemary in Colorado is selecting the right variety. Some varieties are more cold-hardy than others, and certain types are better suited for specific uses.
- ‘Arp’ Rosemary: This variety is known for its strong fragrance and upright growth habit. It’s a good choice for culinary use and attracts pollinators.
- ‘Miss Jessopp’s Upright’ Rosemary: This variety is particularly cold-hardy and can withstand temperatures down to -10 degrees Fahrenheit. It’s a good choice for colder regions of Colorado.
- ‘Tuscan Blue’ Rosemary: This variety is known for its beautiful blue-green foliage and strong flavor. It’s a good choice for both culinary and ornamental use.
Planting Time and Location
The best time to plant rosemary in Colorado is in the spring, after the last frost. Choose a sunny location with well-drained soil. Rosemary prefers a pH of 6.0 to 7.0. If your soil is too acidic, you can amend it with lime.
Planting Your Rosemary
1. Prepare the soil: Dig a hole twice as wide and as deep as the rosemary’s root ball.
2. Amend the soil: Mix in some compost or other organic matter to improve drainage and fertility.
3. Plant the rosemary: Place the rosemary in the hole, making sure the top of the root ball is level with the ground.
4. Water thoroughly: Water the rosemary deeply to help it establish its roots.
Watering and Fertilizing
Rosemary is drought-tolerant, but it does need regular watering, especially during the first year after planting. Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
Fertilize your rosemary in the spring with a balanced fertilizer. You can also use a slow-release fertilizer to provide nutrients throughout the growing season.
Protecting Your Rosemary from Colorado’s Winters
While some rosemary varieties are cold-hardy, they can still be damaged by harsh winters. To protect your rosemary, consider the following:
- Mulching: Apply a layer of mulch around the base of the plant to insulate the roots and prevent frost heave.
- Winter protection: In colder regions, you can further protect your rosemary by covering it with burlap or a frost blanket.
- Potted rosemary: If you’re growing rosemary in a pot, bring it indoors or place it in a sheltered location during the winter.
Pruning Your Rosemary
Pruning your rosemary regularly will help it maintain its shape and encourage bushier growth. Prune your rosemary in the spring, after the last frost. You can also prune it lightly throughout the growing season to remove any dead or damaged branches.
Harvesting Your Rosemary
Rosemary is ready to harvest when it is about 6 inches tall. You can harvest the leaves by snipping them off with scissors or by pinching them off with your fingers.
