Key Takeaways
1. Plant lavender in Colorado after the last frost, typically in late spring or early summer, to avoid damage from freezing temperatures.
2. Choose a well-draining site that receives at least 6 hours of direct sunlight daily and has good air circulation.
3. Prepare the soil by removing weeds and improving drainage with organic matter, such as compost. Avoid high nitrogen fertilizers that may promote leafy growth rather than blooming.
4. Dig a hole slightly larger than the lavender plant’s root ball and place it in the hole, ensuring the top of the root ball is level with the soil surface, neither deeper nor higher.
5. Water newly planted lavender thoroughly and deeply, then regularly but sparingly thereafter, allowing the soil to dry slightly between waterings. Apply a layer of mulch around the plant to help retain moisture and prevent weed growth.
When is the Best Time to Plant Lavender in Colorado?
Climate and Soil Conditions
Before planting lavender in Colorado, it is crucial to understand the climate and soil conditions that are suitable for this aromatic herb. Lavender thrives in well-drained soil with a pH level between 6.7-7.3. Colorado’s climate consists of cold winters and dry, hot summers, so it is essential to choose a variety that is tolerant of these conditions.
Choosing the Right Lavender Variety
When deciding on the ideal time to plant lavender in Colorado, the choice of variety plays a significant role. Some varieties like English lavender (Lavandula angustifolia) and Lavandin (a hybrid of English lavender and spike lavender) are hardy enough to withstand Colorado’s colder temperatures and are well-suited for planting in the state.
Spring Planting
Spring is generally considered the best time to plant lavender in Colorado, as it allows the plants to establish strong roots before the scorching summer heat. Aim to plant lavender in late spring, once the risk of frost has passed and the soil temperature has warmed up to around 50-60°F (10-15°C).
Preparing the Soil
Proper soil preparation is essential for successful lavender cultivation in Colorado. Start by removing any weeds or grass from the planting area. Lavender requires well-drained soil, so consider adding organic matter or sand to improve drainage. Additionally, ensure the soil is loosened to a depth of at least 12 inches (30 cm) to promote root growth.
Planting Technique
When planting lavender, make sure to space the plants 2-3 feet apart to allow proper air circulation. Dig a hole slightly larger than the root ball, place the plant in the hole, and backfill with soil, gently firming it around the base. Water the newly planted lavender thoroughly.
Caring for Lavender in Colorado
After planting lavender, proper care is crucial to ensure its successful growth in Colorado’s challenging climate. Water the plants regularly, especially during the first year, to establish deep roots. However, be cautious not to overwater, as lavender is susceptible to root rot. Apply a layer of mulch around the plants to help retain moisture and suppress weed growth. Prune the lavender plants in early spring to promote bushy growth and remove any dead or diseased branches.
Harvesting Lavender
Once your lavender plants have fully matured, typically after two to three years, you can start harvesting the aromatic blooms. The ideal time to harvest lavender in Colorado is in late spring or early summer when the flower buds have formed but are not fully open. Cut the flower stems just above the foliage and hang them upside down in a warm, dry, and dark place to dry. Once the flowers are thoroughly dried, you can remove the buds for use in various culinary, crafting, or aromatic endeavors.
