How long to dry out lavender depends on the method you choose, but most bundles take about two to four weeks to fully dry when hung in a cool, dark, and well-ventilated space.
If you’re using a dehydrator or oven, you can cut that drying time down to just a few hours.
Either way, the goal is the same: dry out your lavender slowly enough to keep its color, scent, and shape intact.
In this post, we’ll walk through exactly how long to dry out lavender, the best ways to do it, and how to tell when your lavender is fully dried.
Let’s get into it.
How Long to Dry Out Lavender
So how long to dry out lavender really comes down to your drying method.
Air drying is the most traditional approach and usually takes two to four weeks from harvest to fully dry.
Here’s a closer look at each method and how long each one takes.
1. Air Drying Takes 2 to 4 Weeks
Air drying is the classic way to dry out lavender, and it’s also the slowest.
When you hang bundles in a dark, dry room with good airflow, expect to wait about two to four weeks before the lavender is completely dry.
Humidity plays a big role here, so if you live somewhere damp, it may take closer to four weeks to dry out lavender fully.
2. Dehydrator Takes 2 to 4 Hours
If you’re wondering how long to dry out lavender using a dehydrator, the answer is much faster.
Set your dehydrator to around 95°F to 115°F and let the lavender dry for two to four hours.
Check on it every hour, because it can go from perfectly dry to brittle pretty quickly.
3. Oven Drying Takes 1 to 3 Hours
You can also dry out lavender in the oven on the lowest setting, usually around 100°F.
Keep the oven door slightly open so moisture can escape, and expect drying to take one to three hours.
This method works, but it’s easy to overdry lavender and lose some of that wonderful scent.
Best Way to Dry Out Lavender
Now that you know how long to dry out lavender, let’s talk about how to do it right so you get the best results.
1. Harvest at the Right Time
The best time to cut lavender for drying is in the morning, right after the dew has dried but before the sun gets too hot.
Choose stems where the buds are still closed or just starting to open, since these hold their scent best.
2. Bundle and Hang in a Dark Space
Gather a small handful of stems and tie them together with twine or a rubber band.
Hang the bundles upside down in a dark, dry, well-ventilated room, and let them dry out lavender naturally over the next couple of weeks.
3. Keep Them Out of Direct Sunlight
Sunlight fades lavender’s color and breaks down its oils, so avoid hanging bundles near a bright window.
Keeping them in the dark helps you dry out lavender while preserving that lovely purple hue and fragrance.
4. Give Them Plenty of Airflow
Good air circulation is key, so don’t cram bundles too close together.
A small fan on low nearby can help speed things up, but you still want to dry out lavender slowly for the best quality.
How to Tell When Lavender Is Fully Dried
It’s not just about timing, it’s also about learning to spot when your lavender is truly done.
1. Stems Snap Instead of Bend
The easiest test is to bend a stem.
If it snaps cleanly, your lavender is fully dry, but if it still bends like a rubber band, it needs more time to dry out lavender completely.
2. Buds Feel Dry and Crumbly
Rub a few buds between your fingers, and if they fall apart easily and feel dry, you’re good.
If they feel soft or cool to the touch, keep drying, since moisture left inside can lead to mold.
3. The Scent Is Still Strong
Properly dried lavender should still smell sweet and floral.
If the scent has faded, you may have waited too long or dried it out too quickly, so pay attention as you dry out lavender next time.
So, How Long to Dry Out Lavender?
How long to dry out lavender depends on your method, but air drying usually takes two to four weeks, while a dehydrator or oven can finish the job in just a few hours.
No matter which route you choose, the key is to dry out lavender slowly, keep it out of direct light, and make sure it’s fully dry before storing it.
With a little patience, you’ll have beautifully dried lavender ready for sachets, teas, and homemade crafts.
