Lavender is a strong, fragrant plant that makes any garden look and smell better. Pruning is necessary to keep it growing well and producing plenty of flowers. If not trimmed regularly, lavender can become woody and stop producing new shoots. The proper methods will help the plant stay healthy, grow fresh stems, and bloom every season. This guide will show you how to prune lavender correctly to remain whole, fresh, and strong for many years.
Understanding Lavender Pruning
How to Prune Lavender
Pruning helps lavender keep a neat shape, grow more flowers, and stay strong. Use sharp garden scissors or pruning shears to remove about one-third of the plant’s growth yearly. Never cut into old, thorny stems because lavender does not grow back from them. The goal is to keep the plant compact and round. Regular trimming also helps air move through the plant, keeping it dry and preventing disease.
Why Pruning is Essential for Lavender Health
Pruning is more than just making the plant look nice. It helps it stay healthy. Here’s why trimming your lavender is essential:
- Encourages Bushy Growth: Cutting the plant correctly makes it fuller and helps prevent gaps.
- Increases Flower Production: Regular pruning helps the plant focus on growing more flowers instead of stems.
- Stops the Plant from Becoming Woody: If lavender is not trimmed, it develops thick, hard stems that do not produce leaves or flowers.
- Prevents Disease: Trimming lets air circulate through the plant, reducing the chance of mold and mildew.
- Keeps the Plant Alive Longer: A well-maintained lavender plant can live for more than 10 years, while an untrimmed one may stop growing well after just a few seasons.
When to Prune Different Types of Lavender
How and When to Prune Different Types of Lavender
Different lavender types need different pruning schedules. Knowing which kind you have will help you trim it correctly.
How and When to Prune English Lavender (Lavandula angustifolia)
- Best time to prune: Late summer or early fall, after the flowers have faded.
- How to prune: Cut back about one-third of the plant, shaping it into a round form. Leave some green growth to help it grow back.
- Why it matters: English lavender is slow-growing. If not pruned regularly, it becomes woody and produces fewer flowers.
How and When to Prune English Hybrids (Lavandula x intermedia)
- The best time to prune is mid to late summer, once the flowers begin to fade.
- How to prune: Remove about one-third of the plant, keeping its natural shape.
- Why it matters: English hybrids are larger than other lavender types, so shaping them helps control their size and prevents thick woody stems from forming.
How and When to Prune Non-English Lavender (French, Spanish, Wooly, etc.)
- The best time to prune is in early spring and lightly after flowering in summer.
- How to prune: Trim gently to keep the shape, but avoid cutting too much because these plants are more delicate.
- Why it matters: These types do not respond well to aggressive pruning. Light trimming encourages new growth without harming the plant.
Step-by-Step Guide to Pruning Lavender
When and How to Prune: Essential Techniques
- Use Sharp, Clean Shears: Dull scissors can damage the stems, which may slow down growth. Always use clean, sharp pruning shears.
- Prune at the Right Time: Each lavender type has its best pruning season, but most should be trimmed after flowering.
- Shape the Plant: Trim it into a rounded shape to keep it neat and help it grow evenly.
- Avoid Cutting into Old Wood: Lavender does not grow back from thick, hard stems, so always leave some green growth.
- Remove Spent Flowers: Cutting off faded flowers can encourage a second round of blooming in warmer climates.
