Selecting the Right Lavender Varieties for Colorado

Best Lavender to Grow in Colorado

English lavender is also known as Lavandula angustifolia. It is a popular choice among gardeners in Colorado. Because of its ability to withstand cold temperatures and strong winds.

French lavender (Lavandula dentata) is another great option. It can tolerate more heat and has a longer blooming season compared to English lavender.

There are several other varieties that have been successfully grown in Colorado. These include Grosso, Hidcote, and Munstead lavender. All three of these varieties are highly fragrant. Other recommended varieties include Provence lavender, Royal Velvet lavender, and Phenomenal lavender.

Soil Types and Sunlight Requirements

When selecting your lavender varieties, consider the type of soil you have in your garden. It grows best in Colorado's USDA Hardiness Zones 5 to 7. Lavender prefers well-drained soil. The best soil ph for lavender is 6.5 to 7.5. Colorado's clay and rocky soils may require amending with sand, gravel or compost to improve drainage. Additionally, lavender needs at least 6 hours of sunlight per day.

Preparing the Soil

Importance of Well-Draining Soil

Lavender roots are susceptible to rot in wet or compacted soil. You should create a well-draining environment for your lavender plants. In Colorado's high-altitude climate, this is especially important. Because the soil is naturally more compact due to less microbial activity. Well-draining soil allows for proper drainage and air circulation. This ensures healthy root growth.

Soil Amendment and lavender soil ph

You can incorporate organic matter to improve the drainage of your soil. For example, compost or peat moss. Adding expanded perlite or vermiculite can also help loosen up heavy soil. You should maintain an ideal pH level for optimal lavender growth.

Soil Preparation Steps

Test your soil's pH levels using a soil testing kit or sending a sample to a lab for analysis. If the pH level is too low (acidic), add lime to raise it. If the pH level is too high (alkaline), add sulfur or aluminum sulfate to lower it.

Incorporate organic matter and other soil amendments into your soil. Ensure it reaches a depth of at least 12 inches. Rake the soil to create a smooth surface. Remove any debris or large rocks. Water the soil thoroughly. Let it settle for a day before planting lavender in Colorado.

Proper Spacing and Planting Depth

When growing lavender in Colorado, it is crucial to ensure proper spacing between plants. You should plant lavender at least 2-3 feet apart. Because they can reach a height of up to 30 inches and spread out significantly. The planting hole should be deep enough for the entire root ball to fit comfortably. Make sure the top of the root ball is just below ground level.

How to Grow Lavender in Pots?

Choose a pot 12 inches wide and deep. It will allow the roots to spread out comfortably. The plastic nursery pots should also have good drainage holes to prevent waterlogging.

Fill the container with well-draining soil. Leave enough room for the root ball of the lavender plant. Place the pot in a sunny location and water regularly. Keep the soil moist but not overly saturated.

Sunlight and Watering Requirements

Sunlight Requirements

Lavender needs ample sunlight for proper growth and flower production. You should plant lavender in a location with full sun exposure throughout the day. Your plants will receive the necessary amount of light to thrive.

Watering Recommendations

Lavender has quite drought-resistant once established. Overwatering can be detrimental to its growth. Water your lavender deeply once a week during the growing season. Allow the soil to dry out between watering. This will encourage deep root growth and help prevent issues. For example, root rot.

Watering Techniques

Avoid using a sprinkler system when watering your 1 gallon pot. This can lead to the foliage and flowers becoming wet, which can promote fungal growth. Instead, use a drip irrigation system or a watering hose. Water at the base of the plant. The water will reach the roots without getting the rest of the plant wet.

Colorado's Unique Climate Challenges

Protecting Lavender from Sudden Temperature Changes

Consider planting it near a sturdy structure or tall plant. They can provide shade during the hottest part of the day. Additionally, mulching around the base of the plant. This helps retain moisture and regulate soil temperature.

Dealing with Frost and Snow in High-Altitude Regions

In high-altitude regions, lavender plants are susceptible to frost and snow. Cover them with a light cloth or sheet to protect them from frost. For snow, gently brush it off the plants to prevent breakage and damage.

Pruning Lavender in Colorado

Pruning promotes healthy growth. In Colorado's dry climate, pruning also helps to maintain the plant's shape and prevent it from becoming too lanky or leggy.

Start by removing any dead or damaged stems, as well as dried flowers. Next, trim back any overly long or straggly stems. Maintain a compact and bushy shape. To encourage new growth, cut back about one-third of the plant's overall height. Leave at least two sets of leaves on each stem.

Avoid cutting into the woody parts of the plant. This can damage it and hinder future growth. Prune lavender in the spring, after the plant has produced its first flush of flowers. Avoid pruning in the fall or winter. This can leave the plant susceptible to frost damage.
