Preparing Your Lavender for Drying
Drying lavender plants is a rewarding process that allows you to capture the plant's characteristic perfume and beauty for months, even years, after harvest. Whether you've grown your own lavender or purchased fresh stems, proper preparation is key to ensuring a successful outcome. The goal is to remove moisture without diminishing the essential oils responsible for the scent, or fading the vibrant colour of the flowers. This initial step sets the foundation for whatever drying method you ultimately choose.
Begin by selecting the right time to harvest your lavender. For drying, it's generally best to cut the stems when the buds are mostly formed but before they have fully opened. The plant's oils are most concentrated at this stage, promising the strongest fragrance. Use clean secateurs or sharp scissors to make cuts, taking care not to damage the foliage. Aim to harvest in the morning, after the dew has evaporated but before the midday sun becomes too intense, as this is when the plant's volatile oils are at their peak.
Once harvested, remove any leaves that sit below the lowest flower buds. These lower leaves are more prone to mildew when drying and do not contribute to the visual appeal once the stems are bundled. You should also inspect the stems for any signs of pests or disease. It is crucial to work with clean, healthy plant material to prevent mould or spoilage during the drying process. If you are using lavender grown for culinary purposes, ensure it is from a source free from pesticides and that you have thoroughly rinsed and dried the exterior surface, though for pure fragrance drying, this rinsing is often omitted.
Choosing the Right Lavender Variety
While most lavender varieties can be dried, some are better suited than others due to their oil content and bloom structure. English lavenders, such as 'Hidcote' and 'Munstead', are exceptionally popular for drying. Their compact flower spikes hold their shape and fragrance well. French lavender (Lavandula dentata) and Spanish lavender (Lavandula stoechas) have more delicate structures and often lose their bracts more easily, making them less ideal for traditional drying methods, though they can still be used for decorative purposes if handled carefully.
When harvesting, consider the length of your stems. For bundling and hanging, longer stems are preferable. If you plan to use the dried flowers in potpourri or sachets, shorter stems might be more manageable. Ensure you have enough material for the chosen drying method; larger bundles can sometimes lead to mould if air circulation is poor, while individual stems might require more space.
The moment of harvest dictates the potency of the dried product.
Effective Methods for Drying Lavender
Several tried-and-tested methods can be employed to dry lavender plants, each offering slightly different results in terms of colour retention, fragrance intensity, and time taken. The most traditional and often preferred technique is air drying, which relies on low humidity and good ventilation to slowly remove moisture from the plant material.
Air Drying (Hanging Method)
This is the classic approach. Gather your prepared lavender stems into small bundles, typically no more than ten to twelve stems per bundle. Secure the base of each bundle with an elastic band or twine. Using elastic bands is advantageous as they contract as the stems dry and shrink, maintaining tension and preventing the bundles from loosening, which could lead to dropped flowers. Hang these bundles upside down in a dark, dry, and well-ventilated location. A shed, attic, or spare room with minimal light exposure works well. Light can bleach the colour, while high humidity can encourage mould. Allow 7 to 14 days, or sometimes longer, for the lavender to dry completely. The flowers should feel dry and papery, and the stems should be brittle.
Oven Drying
For a quicker result, oven drying can be an option, though it requires careful monitoring to avoid 'cooking' the lavender and losing its precious oils. Preheat your oven to its lowest possible setting, ideally between 75°C and 100°C (165°F and 210°F). Spread the lavender stems in a single layer on a baking sheet lined with parchment paper. Place the baking sheet in the oven. You will need to prop the oven door open slightly to allow moisture to escape. This method typically takes 2 to 4 hours, but you must check the lavender frequently, turning the stems occasionally, until they are dry and brittle. This technique can sometimes result in a slightly less vibrant colour and fragrance compared to air drying.
Microwave Drying
Another rapid method is microwave drying. Place a layer of lavender stems between two sheets of paper towel on a microwave-safe plate. Microwave on a low power setting (e.g., 30-second intervals) until dry. This method is very fast, often taking only a few minutes, but it requires extreme vigilance to prevent scorching. It's best suited for small quantities and can be unpredictable.
Ventilation is paramount for preventing mould during any drying process.
Implement a preliminary drying period for very moist stems by laying them out on trays in a warm room for a day or two before bundling for air drying, especially if your ambient humidity is high.
Post-Drying Care and Storage
Once your lavender plants are thoroughly dried, the next crucial step is proper storage to preserve their quality. Incorrect storage can lead to loss of fragrance, colour fading, or even pest infestation, undoing all your hard work. The aim is to keep them protected from light, moisture, and strong odours.
Stripping the Flower Heads
For many applications, you'll want to separate the dried flower heads from the stems. This is easily done by gently running your fingers down the stem, stripping the blooms into a clean container or a tray. Alternatively, you can place the dried bundles in a large paper bag and shake gently to dislodge the flowers. The stems themselves can also be saved for decorative purposes or to infuse sachets with a more subtle scent. Store the stripped flower heads separately from the stems.
Storage Containers and Conditions
Store your dried lavender in airtight containers. Glass jars with tight-fitting lids are ideal, as they are non-porous and prevent moisture and odours from entering. Large ziplock bags can also be used, but ensure all air is expelled before sealing. The key is to keep the dried flowers in a cool, dark place. A cupboard or drawer away from direct sunlight and heat sources will help maintain their colour and fragrance for longer. Avoid storing them in plastic containers that may 'sweat' and introduce moisture, which can lead to mould or degradation.
Light exposure is the primary enemy of dried lavender's vibrant hue.
If you are drying lavender for culinary use, it is vital to ensure it was grown specifically for consumption and has not been treated with any chemicals. Store culinary-grade dried lavender in separate containers from ornamental dried lavender to prevent cross-contamination of scents and potential allergens.
Maximising Fragrance Longevity
To enjoy the scent for as long as possible, handle your dried lavender gently. When using lavender in sachets or potpourri, a gentle squeeze can release more fragrance. If the scent begins to fade, you can sometimes revive it by adding a few drops of pure lavender essential oil to the dried flowers, though this alters the natural aroma. For ornamental displays, simply keep them out of direct sunlight and humidity.
The quality of your initial harvest and drying process will directly impact how long your dried lavender remains potent.
Creative Uses for Dried Lavender
Once you have successfully dried your lavender plants, a world of creative possibilities opens up. Dried lavender is incredibly versatile, lending its aroma and visual appeal to a wide array of projects, from home decor to personal well-being and even culinary creations. Exploring these uses ensures your efforts are well rewarded and your home is filled with the calming scent of lavender.
Home Fragrance and Decor
Perhaps the most popular use for dried lavender is in sachets. These small fabric bags, filled with dried lavender flowers, can be placed in drawers, wardrobes, or linen cupboards to impart a fresh, calming scent and deter moths. They make delightful handmade gifts. Lavender also features prominently in potpourri mixes, where its strong fragrance complements other dried flowers and spices. Bunches of dried lavender stems can be used in vases as a beautiful, natural arrangement that requires no watering and continues to offer a gentle perfume. Wreaths and garlands made from dried lavender add a rustic, fragrant charm to any home.
Culinary Applications
Certain varieties of lavender, particularly English lavender, are safe and indeed delicious for culinary use. Dried lavender buds can be incorporated into baked goods such as shortbread, cakes, and cookies, imparting a subtle floral note. They can also be used to flavour syrups, teas, and jams, or infused into oils and vinegars. When using lavender in cooking, a little goes a long way; it’s wise to start with small quantities to avoid an overpowering taste. Ensure you use lavender specifically grown for culinary purposes and dried without any additives.
Dried lavender flowers can infuse liquids or solids with their unique flavour and aroma.
Well-being and Aromatherapy
The therapeutic properties of lavender are well-documented. Dried lavender can be used in warm baths, either in a sachet or loose (though loose buds may require a sieve for removal), to promote relaxation and improve sleep. It's a key ingredient in DIY bath bombs and soaps. For a simple aromatherapy experience, place a small amount of dried lavender in a bowl near your bedside or desk. The gentle release of its scent can help reduce stress and anxiety, contributing to a more peaceful environment. This makes the process of drying lavender plants a direct pathway to enhanced personal well-being.
Crafting with Lavender Stems
Don't discard the stems! Dried lavender stems can be incorporated into various crafts. They can be woven into small decorative items, used as natural embellishments for greeting cards or gift wrapping, or even fashioned into wands or dreamcatchers. The woody nature of the dried stems makes them surprisingly durable for many crafting projects.
When creating lavender sachets, mix dried lavender buds with a small amount of rice or dried orris root to help absorb moisture and fix the fragrance for extended periods.
