Harvest

When
Harvest flower stems in early–mid summer when the bottom third to half of the florets on each spike have opened — for the strongest oil and best bud retention when dried, some pick just as the buds show full color but before opening. Cut mid-morning on a dry day, after dew but before heat.
What to look for
Spikes richly colored, the lowest flowers just opening, and the whole bush humming with scent. Fully open or fading spikes shed buds when dried and have already spent much of their oil.
How to harvest
Cut stems as long as possible, down to just above the leafy growth, gathering a bunch in one hand and cutting with secateurs or a serrated harvest knife. When trimming after harvest, never cut into bare old wood — lavender will not regrow from it.
How often
Most varieties give one main flush per year; cutting the first flush promptly often earns a smaller second flush in late summer, especially from English lavenders. Annual harvest-plus-trim keeps the shrub compact and productive for many years.
Storing the crop
Hang bunches of 50–100 stems upside down in a dark, warm, airy place for 2–4 weeks; darkness preserves the color. Once dry, use stems whole or rub the buds off into jars — dried buds keep their fragrance for a year or more in airtight storage and go into sachets, baking (use culinary varieties), and infusions.

Lavender thrives on neglect — poor, dry soil gives the strongest scent.
