When it comes to harvesting herbs, there are certain rules to follow regarding both the timing and the location where herbs should be gathered. Of course, you should always be cautious—especially if you’re a beginner or unfamiliar with certain plant species. To help you get started, here’s a simple month-by-month guide outlining the best times to harvest various herbs.
Leaves are best picked before or during flowering when their oils and flavors are strongest.
Flowers should be harvested as they begin to fully open.
Roots are usually dug in early spring or late fall, when the plant’s energy is concentrated below ground.
Fruits and seeds should be gathered when fully ripe and dry.
Avoid polluted areas like roadsides or industrial zones, and never overharvest—take only what you need.
What I learned from my grandmother is that if you’re harvesting herbs, you should pick them before noon, as that’s when their healing power is at its strongest. My favorites are St. John’s wort and mint. I also love lavender because it’s excellent for aromatherapy.. St. John’s wort is especially effective for bacterial infections, while mint has a refreshing flavor. If you enjoy iced tea, mint is a great choice. In any case, harvesting herbs is always a unique experience, no matter the time of year.
