Deadheading Lavender for Continuous Blooms
Want to enjoy waves of lavender flowers all summer? Deadheading—the simple act of removing spent flower spikes—can coax your plants into repeat blooming and keep your lavender looking tidy. Here’s how, when, and why to deadhead lavender for the longest, most vibrant flowering season possible.
Why Deadhead Lavender?
- Stimulates new blooms: Removing faded spikes encourages the plant to send out new flower stems.
- Neater plants: Deadheading prevents a scruffy look and helps maintain that classic lavender mound shape.
- Fewer seeds, more flowers: Instead of setting seed, lavenders redirect energy into blossom production—especially in reblooming types.
When to Deadhead Lavender
- First major deadheading: As the initial flush of flower spikes fade and begin to brown (typically July or early August).
- Continue every 1–2 weeks: Remove spent flowers as you spot them to promote ongoing rebloom in summer and into early autumn (particularly for English and lavandin hybrids).
How to Deadhead Lavender
- Use clean, sharp scissors or garden snips.
- Snip individual spent flower stems just above the first set of new, healthy leaves or tiny side shoots below the faded flower.
- In large plantings or hedges: Gather several faded stalks at once and trim with hedge shears—always take care not to cut into brown, leafless wood.
- Remove cuttings from the bed to avoid disease and keep beds tidy.
Which Lavenders Benefit Most?
- English lavenders (“Munstead,” “Hidcote,” “Lady”): Respond brilliantly with a second bloom after deadheading.
- Lavandin hybrids (“Grosso,” “Provence,” “Phenomenal”): Often rebloom if deadheaded and kept watered in dry spells.
- French/Spanish lavenders: May rebloom, but less reliably; deadheading still improves appearance and prevents woody seed heads.
Aftercare: Don’t Skip the Big Prune!
- At the end of summer or after second flush (usually August/September), prune plants back by a third to maintain neat, bushy growth through winter.
Pro Tips
- Deadhead on dry days to avoid spreading disease.
- Pinch off new faded blooms every garden walk—your lavender will reward you with constant color!
- Don’t let plants go to seed if you want maximum flowers; if you want seeds, let some spikes develop fully at summer’s end.
Wrapping Up
Regular deadheading is the secret to continuous lavender flowers and a tidy scented garden. With a few snips a week, you can enjoy extended blooms, stunning borders, and all the pollinator action your garden can handle.
