How to Dry Lavender and Rosemary at Home

The best way to dry lavender and rosemary at home is to bundle small bunches with string, hang them upside down in a dark, dry, well ventilated space such as a shed or airing cupboard, and leave them undisturbed for roughly two to three weeks until the stems snap rather than bend.

This is one of the quieter, more repetitive rituals of my whole year, and it happens to matter enormously for what ends up in my soap.

Why drying method actually matters

Rushing the process, or drying herbs somewhere warm and bright like a sunny windowsill, tends to fade colour and burn off scent before you have even finished the job. Slow, dark, airy drying preserves both far better than anything fast.

The bundling method, step by step

Gather small bundles rather than large armfuls, since thick bundles trap moisture in the centre and risk mould. Tie each bundle firmly near the cut end with string or a rubber band, allowing for slight shrinkage as the stems dry. Hang each bundle upside down, which helps the oils settle toward the flower or leaf rather than draining down the stem.

Where to hang it

A dark shed, a garage, or an airing cupboard all work well. The key requirements are darkness, to protect colour and oil content, and good airflow, to prevent mould. Direct sunlight is the enemy here, however tempting a sunny windowsill looks.

How long it actually takes

Roughly two to three weeks for most bundles, depending on humidity and airflow. The reliable test is the stem itself. If it snaps cleanly rather than bending, it is properly dry. If it still has any flex, it needs longer.

What happens after drying

Once dried, lavender flowers are gently stripped from the stem for use, while rosemary can be left as small sprigs or crumbled depending on how it will be used. In my case, dried lavender becomes part of the botanical element of my fragrance free range, while rosemary, grown steps from where I make soap, sometimes goes from allotment bed to soap mould in the very same afternoon rather than being dried at all, depending on what I am making.

Frequently asked questions

How do you know when dried herbs are ready to use?

The stem should snap cleanly rather than bend. Any flexibility left in the stem means it needs more time.

Can you dry lavender and rosemary in the same space?

Yes, provided bundles are kept separate enough for good airflow around each one, and neither is exposed to direct light.

Does drying lavender reduce its scent?

Properly dried, slowly and in the dark, lavender retains a good amount of its scent. Fast drying in heat or light is what causes the real loss.

Dried lavender from my own allotment is one of the botanicals in my fragrance free range, and you can read more about how that range is built on my website.
