After your lavender plants finish flowering, you should prune them to keep the plants healthy and encourage more blooms next season.
Once the flowers fade, deadheading and trimming back the foliage helps lavender stay bushy instead of getting woody and leggy.
Knowing what to do with lavender plants after flowering is actually one of the most important things you can learn as a lavender grower.
Get this step right, and your lavender will reward you with fuller growth and a bigger harvest next year.
In this post, we’ll walk through exactly what to do with lavender plants after flowering, from deadheading to pruning to overwintering.
Let’s dig in.
What to Do With Lavender Plants After Flowering
What to do with lavender plants after flowering comes down to three simple jobs: deadheading, pruning, and preparing the plant for the colder months.
Each one matters, and doing them in the right order keeps your plant thriving.
1. Deadhead the Spent Blooms
The first thing to do with lavender plants after flowering is remove the faded flower spikes.
Use clean snips to cut each stem back to just above the first set of leaves.
Deadheading stops the plant from wasting energy on seed production.
It also keeps your lavender looking tidy and encourages a second flush of blooms in some varieties.
If you’re wondering what to do with lavender plants after flowering when you want more flowers, this is your answer.
2. Give the Plant a Light Prune
After deadheading, you can lightly prune the whole plant to shape it.
The goal here is to trim the soft green growth without cutting into the old woody stems.
Lavender won’t regrow from old wood, so stay in the leafy zone.
A good rule is to remove about one-third of the green growth.
This keeps the plant compact and prevents that floppy, sprawled look.
Timing matters too: prune right after the main bloom finishes, usually late summer.
That gives new growth time to harden off before winter arrives.
3. Save the Flower Stems
Here’s a bonus when you’re deciding what to do with lavender plants after flowering.
Those cut stems aren’t waste.
Bundle them and hang them upside down in a dark, dry spot for a week or two.
Once dried, you can strip the buds for sachets, teas, or bath salts.
Dried lavender buds are also great for repelling moths in closets.
So part of what to do with lavender plants after flowering is simply harvest and enjoy what you already have.
How to Care for Lavender After Flowering
Once the pruning is done, your lavender still needs a bit of attention to stay strong.
How you water, feed, and position the plant now sets up its next season.
1. Ease Up on Watering
Lavender hates wet feet, so after flowering you should water less often.
Let the soil dry out between waterings.
In containers, this matters even more because pots hold moisture longer than garden beds.
Too much water now can lead to root rot during the damp months.
2. Skip the Heavy Fertilizer
Lavender doesn’t need much food, especially late in the season.
Feeding it now pushes soft new growth that won’t survive the cold.
If your soil is poor, a light sprinkle of compost is plenty.
Otherwise, leave it alone until spring.
3. Make Sure It Gets Full Sun
Lavender thrives in at least six to eight hours of direct sun.
Good light helps the plant dry out after rain and keeps the foliage dense.
If yours is shaded, consider moving it in fall so it settles in before winter.
4. Mulch With Gravel or Sand
A layer of gravel or coarse sand around the base keeps moisture away from the crown.
This mirrors what lavender loves in its native Mediterranean climate.
It also suppresses weeds that compete for nutrients.
Pruning Lavender After Flowering for Winter
As autumn rolls in, what to do with lavender plants after flowering shifts toward winter protection.
1. Do a Final Tidy-Up
Before the first frost, trim any stray stems and remove dead or damaged leaves.
Don’t cut hard, though, because the plant needs its foliage for insulation.
2. Improve Drainage in the Soil
Winter kill usually comes from soggy roots, not cold air.
Mix grit into the soil around the plant if drainage is poor.
Raised beds and slopes work well for lavender too.
3. Protect Potted Lavender
If your lavender lives in a pot, move it against a sunny wall or into a cold frame.
Wrap the pot in bubble wrap or burlap to insulate the roots.
And raise it on feet so water can drain freely.
4. Hold Off on Watering in Winter
Lavender goes semi-dormant in the cold, so it needs very little water.
Only water if the soil is bone dry and the temperature is above freezing.
So, What to Do With Lavender Plants After Flowering?
What to do with lavender plants after flowering is simple: deadhead the spent blooms, give the plant a light prune, and prep it for winter with good drainage and less water.
Do this each year, and your lavender will stay healthy, bushy, and generous with its flowers.
And the dried stems you save?
They’re a little reward that keeps giving long after the garden has gone quiet.
So now you know exactly what to do with lavender plants after flowering, go grab those snips and give your plant the care it deserves.
