Choosing the right time to harvest lavender plays a key role in preserving its fragrance. The best time to cut the flowers is during active blooming, when the buds have already opened but have not yet begun to fade. The ideal moment is in the morning, after the dew has evaporated from the plants. At that time, the concentration of essential oils in the flowers is at its highest, which ensures a rich aroma after drying.
When harvesting lavender, it is important to use sharp garden scissors or pruning shears so as not to damage the plant. The stems should be cut to a length of at least 20–30 cm, leaving some foliage for convenience during drying. If the lavender is intended for decorative purposes, longer stems can be cut, as they will look more attractive in bouquets or arrangements once dried. It is important not to pull the plant out by the root, so that it can continue growing in the next season.
Immediately after cutting, the lavender should be prepared for drying. The leaves on the lower part of the stem can be removed if they are not needed. It is also worth checking the stems for damaged or wilted flowers and removing them. The better the quality of the harvested material, the better the lavender will retain its scent after drying.
One of the most effective methods of drying lavender is air-drying it while hanging. This method helps preserve both the fragrance and the natural shape of the plant. To do this, lavender is gathered into small bunches of 10–15 stems and tied with natural string or an elastic band. It is important not to tie them too tightly, because as the stems dry out, they shrink slightly and the bunch may fall apart.
The bunches are best hung upside down in a dry, dark, and well-ventilated room. Direct sunlight speeds up fading, which can cause lavender flowers to lose the richness of their color. The ideal drying temperature is around 20–25°C.
The drying process takes from one to two weeks, depending on the humidity level in the air. To check whether it is ready, gently bend a stem: if it snaps easily, the lavender is fully dry. After that, it can be carefully taken down and prepared for storage or further use.
If hanging is not suitable, lavender can also be dried by laying it out on a flat surface. A wooden tray, baking sheet, cardboard, or cotton cloth will work well for this. The lavender should be spread in a thin layer so that air can circulate freely between the stems.
It is important not to place the plant in areas with high humidity, as this can cause mold to appear. From time to time, the stems should be turned over so that the drying process happens evenly.
This horizontal method is convenient because lavender keeps its structure and color well. However, some of the flowers may shed slightly during drying, so it is worth sorting through them once again before storage.
For those who want to speed up the drying process, special dryers such as dehydrators can be used. They allow temperature and humidity levels to be controlled, making it possible to dry lavender in just a few hours.
Lavender can also be dried in an oven at the lowest temperature, around 40–50°C. To do this, the flowers are placed on a baking sheet lined with parchment paper and left in the oven, slightly open, for 1–2 hours. It is important to make sure the lavender does not overheat, since that can cause the essential oils to evaporate and the fragrance to be lost.
This method is less desirable than air-drying, but it works well for anyone who needs to dry the plant quickly without a major loss of its qualities.
Once the drying process is complete, it is important to store lavender properly so it does not lose its fragrance. The best option is airtight glass jars or fabric sachets. Plastic containers are best avoided, since they can trap moisture and cause the plant to spoil.
If the lavender is being used for decorative purposes, it can be left in bunches and placed indoors or set in a vase without water. This storage method helps preserve its scent for a long time.
Dried lavender can be used not only in décor, but also for making aromatic sachets, brewing herbal tea, creating cosmetics or soap, and even in cooking by adding it to baked goods or desserts.
A proper drying process helps preserve all the beneficial properties of lavender, its pleasant fragrance, and its attractive appearance, allowing it to be used in many different ways.
