The Core Insight
May is a critical turning point for lavender. By performing light maintenance, including strategic shaping, moisture control, and clearing the base, gardeners can ensure a more robust, fragrant, and long-lasting display throughout the summer months.

The May Turning Point: Why Your Lavender Needs You Now
What You Need to Know
Prune lightly: Only trim new green growth; never cut into old, woody stems.
Prioritize drainage: Lavender hates "wet feet", ensure soil dries out between waterings.
Skip the fertilizer: Lean soil produces more flowers; rich soil only creates excess foliage.
Maximize sun: Ensure at least 6 hours of direct light daily for optimal bloom density.
By the time May arrives, lavender has truly come into its own. The silvery foliage softens, stems stretch, and the first buds begin to form. It is a beautiful stage, but it is also a critical one. What you do in the garden right now dictates the plant's shape and bloom density for the entire summer. If you are planning your seasonal layout, check out our May planting guide to ensure your other perennials are just as successful.

Working With the Seasons
May is the prime window for shaping your lavender. In cooler climates, this is when the plant wakes up from its winter dormancy. In warmer regions, you are preparing the plant for the intense heat of mid-summer. Regardless of your hardiness zone, the goal is to establish a strong, airy structure before the heavy flowering begins.
I have learned the hard way that lavender is not a plant that appreciates "helicopter parenting." I once over-fertilized a row of English lavender, hoping for a massive bloom, only to end up with a sprawling, leafy mess that barely flowered. Lavender thrives on a Mediterranean-style "neglect." It wants sun, sharp drainage, and very little interference. This philosophy is similar to the strategic neglect method we recommend for other high-maintenance crops.
The Unpopular Opinion
Most gardeners believe that more fertilizer equals more flowers. With lavender, this is dead wrong. Feeding lavender actually stunts its natural flowering cycle by forcing the plant to prioritize vegetative growth over reproductive blooms. If your soil is poor, a light dusting of compost is the absolute maximum you should provide. For more on how to manage your soil health without over-complicating it, see our guide on long-haul garden maintenance.
Sustainability in the garden starts with choosing the right plant for the right spot. Lavender is naturally drought-tolerant, meaning it requires less water than almost any other perennial in your border. To keep your garden organic and water-wise, use gravel or grit around the base of your plants. This mimics their native rocky habitats, improves drainage, and suppresses weeds without the need for synthetic chemicals. For more sustainable practices, consider swapping out invasive species using our native plant swap guide.

The Decision Matrix
Not sure if your lavender needs attention? Use this quick check:
Is the soil damp? Stop watering. Let it dry out completely.
Are there weeds at the base? Use a tool like Grampa's Weeder to remove them without disturbing the root ball.
Is the plant getting less than 6 hours of sun? Move the container or prune back overhanging branches.
Why You Can Trust This
I have spent years working with Mediterranean perennials, observing how they respond to different soil compositions and pruning techniques. My advice is based on the biological reality of the plant, specifically its need for airflow and low-nutrient environments. I have vetted these methods against standard horticultural practices from the University of Minnesota Extension to ensure you get the best results without unnecessary labor.
The Lazy Gardener's Shortcut
If you want to extend your flowering season, don't wait for the whole plant to bloom. Start "light harvesting" as soon as the first flowers open. By snipping stems for indoor vases, you are essentially deadheading the plant in real-time, which tricks the lavender into producing a second, often more vigorous, flush of blooms.
Pairing your lavender with companions like rosemary, salvias, and echinacea creates a cohesive, low-maintenance display that looks intentional and refined. Once you have finished your light shaping and weeding, step back. Let the plant settle into its natural rhythm. By the time summer hits, you will have a fragrant, full, and resilient display.
Do you prefer the classic, uniform look of a manicured lavender hedge, or do you let your plants grow into their natural, wilder shapes? I will be in the comments for the next 24 hours to discuss your garden plans.
No. Fertilizing lavender is counterproductive as it encourages excess foliage growth at the expense of flowers. Lavender prefers lean soil.
Lavender requires at least 6 hours of direct sunlight daily to maintain optimal bloom density.
You can encourage a second flush by 'light harvesting' or deadheading the plant as soon as the first flowers open, which tricks the plant into producing more blooms.
