Creating a Lavender Hedge: Planting Distance and Considerations

Lavender is a lovely and versatile plant that not only adds beauty to your garden, but also fills the air with its enchanting fragrance. If you’re considering creating a lavender hedge, proper planting distance is crucial to ensure healthy growth and an aesthetically pleasing result. In this article, we will explore the ideal spacing for planting lavender to form a hedge, as well as important considerations to keep in mind.

1. Understanding Lavender Varieties and Characteristics

Before getting into the specifics of planting distances, it’s important to understand the different varieties of lavender and their growth habits. Lavender belongs to the genus Lavandula, which includes a wide range of species and cultivars. Common species used for hedges include Lavandula angustifolia, Lavandula x intermedia, and Lavandula stoechas.
Each variety of lavender has its own growth characteristics, such as height, spread, and overall shape. For example, Lavandula angustifolia tends to have a compact growth habit, making it a popular choice for low hedges. Lavandula x intermedia, on the other hand, can grow taller and wider, making it suitable for larger hedges or border plantings. Understanding these characteristics will help you determine the appropriate spacing for your lavender hedge.

2. Optimal planting distance for lavender hedges

The ideal planting distance for a lavender hedge depends on several factors, including the variety of lavender, the desired height and width of the hedge, and the specific growing conditions in your garden. As a general guideline, aim for a distance of 12 to 18 inches (30 to 45 cm) between each lavender plant when creating a hedge.
This spacing allows enough room for the plants to grow and fill in the gaps, creating a dense and visually pleasing hedge. However, if you’re using a larger variety of lavender or want a more substantial hedge, you may need to increase the spacing to 18 to 24 inches (45 to 60 cm) to accommodate their growth potential. Keep in mind that lavender plants will naturally spread out as they mature, so it’s important to consider their final size when determining the planting distance.

3. Important considerations when planting lavender hedges

When planting lavender for a hedge, there are several important considerations to ensure the success and longevity of your fragrant border. First and foremost, lavender thrives in well-drained soil with good air circulation. It’s important to choose a location that receives full sun for at least six to eight hours a day.

In terms of soil, lavender prefers a slightly alkaline pH between 6.5 and 7.5. If your soil is acidic, you may need to add lime to raise the pH. Also, make sure the soil is loose and not too compacted, as lavender roots require good drainage to prevent waterlogging, which can lead to root rot.

4. Planting and Care Tips for Lavender Hedges

When planting lavender for a hedge, follow these tips to ensure healthy establishment and continued growth:

– Prepare the soil by removing any weeds or grass and loosening it with a garden fork or tiller.

– Dig a hole slightly larger than the root ball of the lavender plant.

– Place the plant in the hole, making sure the top of the root ball is level with or slightly above the surface of the soil.

– Backfill the hole with soil, gently compacting it around the plant.

– Water thoroughly after planting and keep the soil moist for the first few weeks.

– Once established, lavender is drought tolerant and requires minimal watering. Water deeply but infrequently to encourage deep root growth.

– Prune your lavender hedge in early spring or after flowering to maintain shape and encourage bushier growth.

5. Enhancing the Fragrance of Your Lavender Hedge

To fully enjoy the intoxicating fragrance of your lavender hedge, consider adding companion plants that complement the scent. Herbs such as rosemary, thyme, and sage not only share similar growing conditions, but also enhance the overall scent of your garden.
In addition, interplanting lavender varieties with different bloom times can provide a continuous display of color and fragrance throughout the growing season. Varieties such as Lavandula angustifolia ‘Hidcote’ and Lavandula x intermedia ‘Grosso’ can be combined for a stunning and aromatic effect.

In conclusion, creating a lavender hedge requires careful consideration of planting distance, lavender varieties and growing conditions. By following the guidelines outlined in this article, you can create a beautiful and fragrant lavender hedge that will bring joy to your garden for years to come. Remember to choose the proper spacing based on the lavender variety and desired hedge size, provide optimal growing conditions, and implement proper planting and maintenance techniques. With a little patience and attention to detail, you’ll soon have a captivating lavender hedge that not only adds visual appeal, but also fills the air with its delightful scent.


How far apart do I plant lavender for a hedge?

When planting lavender for a hedge, it is recommended to space the plants approximately 18 to 24 inches (45 to 60 centimeters) apart. This spacing allows the plants to grow and fill in the gaps, creating a dense and uniform hedge.

What factors should I consider when spacing lavender plants for a hedge?

Several factors should be considered when spacing lavender plants for a hedge. These include the specific lavender variety, the desired height and width of the hedge, and the growing conditions in your area. It’s important to choose a variety that is suitable for hedging and to provide enough space for each plant to grow and thrive.

Can I plant lavender closer together for a denser hedge?

While it may be tempting to plant lavender closer together to achieve a denser hedge more quickly, it is generally not recommended. Lavender plants need proper air circulation and room for their roots to spread out. Planting them too closely together can lead to poor airflow, increased risk of disease, and competition for resources, which can negatively impact their growth and overall health.

How long does it take for lavender to form a hedge?

The time it takes for lavender to form a hedge can vary depending on several factors, including the lavender variety, growing conditions, and care provided. Generally, it takes about 2 to 3 years for lavender plants to grow and fill in the gaps, forming a solid hedge. Regular pruning and maintenance can help promote bushier growth and faster hedge formation.

Can I trim my lavender hedge to maintain its shape?

Absolutely! Trimming your lavender hedge is an important part of maintaining its shape and promoting healthy growth. It is best to prune lavender in early spring, just as new growth begins. Trim back the previous year’s growth by about one-third, cutting just above a pair of healthy leaves. Regular pruning helps keep the hedge compact, encourage new growth, and prevent the plants from becoming woody and leggy.
