In a quiet spot in my garden accompanied by St. Francis, patron saint of animals and the environment, I have two rows of Provence lavender growing. For my lavender, it is usually the end of June, beginning of July, when the lavender spikes begin to flower and it is time to harvest for drying. I don’t harvest all the lavender, so as to save some of the lavender for the bees, butterflies, and pollination.
Lavender spikes are ready to harvest when the bottom third of the spike starts to bloom. Make sure lavender spikes are totally dry and not wet from morning dew. Gather your lavender spikes in bundles, tie together with twine, and hang upside down on a wire hanger. I use a simple paperclip to secure my lavender bunch to the hanger. For a small amount of lavender bundles, hang in a dark, dry place with air circulation, like a guest bedroom closet. Place a towel or cloth under your lavender bunches to catch any lavender that drops. Drying in a dark space or closet will preserve the color of the lavender flowers, which will dry in 8 to 10 days. Rub your dried flower heads together over a sieve to separate anything other than your prized lavender buds. Store in an airtight glass jar, either tinted or in a dark pantry. Dried lavender will keep their flavor for culinary use, for many years, but I try and harvest enough lavender buds to last me until next year.
Lavender plants need to be cut back to beautiful mound shapes each year once harvest and their bloom time is over. Cut back your lavender plants by about one half in size and just above their woody stems. This will rejuvenate your lavender plants for the following year.
