- Lavandin (Lavandula x intermedia): A hybrid of English and Portuguese lavender, lavandin is known for its high oil yield and strong scent. It blooms later in the summer and is often grown commercially. Lavandins are generally larger and more vigorous growers than English lavender.
- Spanish Lavender (Lavandula stoechas): This variety has distinctive bracts (petal-like structures) at the top of its flower spikes. It blooms in spring and early summer. Spanish lavender is less cold-hardy than English lavender.
Identifying Your Lavender Variety
If you’re unsure of your lavender variety, observe its characteristics. Note the leaf shape, flower color, bloom time, and overall plant size. Compare these observations with descriptions of different lavender varieties. Consulting with a local nursery or garden center can also help you identify your lavender variety accurately. Knowing the variety is crucial for determining the best harvesting time and technique.
The Optimal Timing for Harvesting Lavender
Timing is critical when it comes to harvesting lavender. Harvesting at the wrong time can result in a weaker fragrance and a less successful harvest. The optimal time to harvest lavender depends on the variety and your intended use for the blooms.
Harvesting for Culinary Purposes
For culinary use, harvest lavender flowers just as the buds are beginning to open. This is when the flavor is most potent. Harvest in the morning, after the dew has dried but before the heat of the day sets in. This is when the essential oils are most concentrated. Early morning harvests also result in less moisture in the buds, which is beneficial for drying.
Harvesting for Essential Oil Production
For essential oil production, harvest lavender when most of the buds are open. This is when the oil yield is at its peak. Again, harvest in the morning for the best oil concentration. The stage of bloom directly impacts the quantity and quality of essential oil you can extract. Harvesting at the right time ensures you’re maximizing your yield.
Harvesting for Dried Flowers
For dried flowers, harvest lavender when the flower spikes are about half to three-quarters open. This allows the blooms to retain their color and fragrance as they dry. Harvesting at this stage also helps to prevent the flowers from shattering during the drying process. Dried lavender is perfect for sachets, potpourri, and decorative arrangements.
General Harvesting Guidelines
Regardless of your intended use, avoid harvesting lavender during or immediately after rain. Water can dilute the essential oils and increase the risk of fungal diseases. Also, avoid harvesting during the hottest part of the day, as this can cause the essential oils to evaporate. The cooler morning temperatures are ideal for preserving the plant’s valuable oils.
Essential Tools for Harvesting Lavender
Having the right tools makes the harvesting process easier and more efficient. Using the appropriate tools will also help you avoid damaging your lavender plants. Investing in quality tools will ensure a successful and enjoyable harvesting experience.
Pruning Shears or Scissors
Sharp pruning shears or scissors are essential for cleanly cutting the lavender stems. Choose shears with bypass blades, which provide a clean cut without crushing the stems. Regular scissors can also work, but make sure they are sharp to avoid tearing the stems. Sharp cuts promote faster healing and prevent the spread of disease.
Harvesting Basket or Container
