Best Way To Trim Lavender in Spring and Fall For More Flowers

Sharing is caring!

Lavender, with its alluring fragrance and vibrant blooms, is a staple in many gardens. However, to maintain its beauty and vigor, proper trimming is essential.

Pruning not only encourages a lush display of flowers but also prevents the plants from becoming too woody, which can diminish their health and aesthetic appeal.

In this guide, we’ll explore the best practices for trimming lavender in the spring and fall, ensuring your plants remain as captivating as they are fragrant.

Understand Lavender Growth Patterns

Understanding the growth pattern of lavender is crucial for effective pruning. Lavender is a perennial that thrives on routine trimming.

The plant typically blooms on the new shoots that grow from the previous year’s wood, making timely pruning essential to promote these new shoots.

There are several types of lavender, including English, French, and Spanish varieties, each with slightly different care requirements. English lavender is the most common and hardiest, often requiring pruning in late spring.

French lavender can handle warmer climates and might need a light trim in spring and summer. Spanish lavender prefers hot conditions and usually benefits from post-bloom pruning.

Essential Tools for Trimming Lavender

Before you begin pruning your lavender, ensure you have the right tools. A pair of sharp pruning shears is essential, as blunt blades can damage the stems and make the plant susceptible to disease.

Gloves are advisable to protect your hands from the plant’s oils and any sharp branches. Keeping your tools clean and sharp will help you make precise cuts and avoid harming the plant.

Best Practices for Spring Trimming

Spring is a critical time for pruning lavender, as it sets the stage for the growing season:


Begin pruning as soon as new growth appears at the base of the plant, typically in late spring. This timing helps prevent frost damage to new cuts and ensures the plant’s energy is directed to vibrant new growth.


When trimming, aim to remove about one-third of the current season’s growth. Make your cuts just above new shoots on the stem, ensuring you do not cut into the woody part of the plant, which can be slow to regenerate.


Maintain a rounded shape as you trim, which promotes even growth and airflow around the plant, reducing the risk of disease.

Fall Pruning Techniques

Fall pruning is geared more towards maintenance and preparation for winter rather than stimulating growth. It’s the time to tidy up the plant after the main blooming period and before the onset of winter:


Perform fall pruning after the last blooms have faded but before the first frost. This timing helps the plant to harden off and better withstand cold weather.


Unlike spring, fall pruning should be lighter. Remove any spent flowers and dead branches to prevent decay and disease over the winter. This cleanup helps maintain the health of the plant and ensures a robust start in the spring.

Seasonal Lavender Care Tips

Alongside timely pruning, proper care throughout the year can significantly influence the health and flowering of your lavender plants.

Watering needs to be handled with care; lavender prefers drier conditions, so ensure the soil has excellent drainage and water sparingly.

Over-watering can lead to root rot, which is a common issue with lavender. Feeding is another aspect to consider.

A light application of a balanced, slow-release fertilizer at the beginning of the growing season can support healthy growth without encouraging the soft, lush foliage that is susceptible to disease.

Mulching with gravel or small stones can help reflect heat back onto the plant, promoting growth and preventing excessive moisture around the base, which could cause decay.

Regularly check your plants for signs of stress, such as discolored leaves or stunted growth, which could indicate pest issues or disease. Early detection and treatment can save a plant that might otherwise succumb to illness.

Common Mistakes to Avoid While Trimming

Pruning lavender is generally straightforward, but common mistakes can hinder the health and aesthetic of your plants.

One major error is cutting too far into the woody base of the plant. Lavender does not regenerate well from old wood, so cuts should always be made above the point where there is clear green growth.

Another frequent mistake is over-pruning; removing too much foliage at once can stress the plant, leading to reduced blooming and vitality.

It’s also vital not to neglect the timing of your pruning. Late pruning in the fall, especially in colder climates, can leave new growth vulnerable to freezing temperatures, while too early spring pruning might lead to frost-damaged new shoots.

Advanced Pruning Techniques for Mature Lavender Plants

For mature lavender plants that have become woody, more intensive rejuvenation techniques may be necessary.

One effective method is coppicing, which involves cutting back the plant almost to the ground to encourage new growth from the base.

This can be risky and should only be done in early spring to give the plant the full growing season to recover.

Another technique is renewal pruning, where you selectively remove older branches over several years to rejuvenate the plant without shocking it by removing too much at once.

This gradual approach allows the lavender to maintain its shape and vigor, encouraging fresh growth from the roots up, while still clearing out old, non-productive wood.

By following these detailed care instructions and pruning techniques, your lavender will continue to thrive and embellish your garden with its iconic scent and color.

Regular pruning not only enhances the plant’s appearance but also its health, ensuring a bounty of blooms and a robust structure for years to come.

Remember, the key to successful lavender care lies in understanding its needs and responding with the right techniques at the right time.
