收割薰衣草。 将薰衣草放在一块木头上。 把薰衣草放在阳光充足的地方。 让阳光将薰衣草彻底晒干。

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
Harvest lavender just before the buds open. Cut at the base of the stems to preserve as much stem as possible. A cutting board or another large piece of wood is perfect for drying lavender in the sun. If you use a metal tray, the lavender will get too hot; if you use plastic, you might have a melted mess on your hands. Move the cutting board or wood block to a place that gets plenty of sun, either indoors or outdoors. Drying lavender this way is a much quicker process than drying it in the dark,
