Late summer is the most abundant time in the herbal year. Here are the plants to gather, dry, and preserve before the season turns.
Late summer is the most generous season in the herbal year. The sun has done its work — concentrating volatile oils, deepening roots, and ripening seeds. If you grow herbs or have access to wild spaces, right now is the time to fill your apothecary shelves for the months ahead.
Here's what I'm harvesting at Willow's Apothecary this August, and how I'm preserving each one.
Lemon Balm (Melissa officinalis)
Lemon balm is at its most fragrant just before it flowers. Once the tiny white blooms open, the volatile oils that give it that bright, lemony scent begin to dissipate. Harvest the top third of the plant on a dry morning after the dew has lifted.
What I use it for: Nervine support, sleep blends, digestive ease, and uplifting teas. Lemon balm is one of the gentlest herbs in the apothecary — safe for children and elders alike.
How to preserve it: Dry in small bundles hung upside down in a warm, airy space away from direct light. It dries quickly — usually 5 to 7 days. Store in a sealed glass jar away from heat.
Elderberry (Sambucus nigra)
If you have an elder tree, August through September is berry season. The clusters turn deep purple-black when ripe. Harvest the entire cluster with scissors and strip the berries at home — raw elderberries contain compounds that can cause nausea, so they're always cooked or tinctured before use.
What I use it for: Immune support syrups, oxymel, and winter wellness preparations. Elderberry is one of the most researched herbs for seasonal immune support.
How to preserve it: Simmer into syrup with raw honey, ginger, and cinnamon. Freeze fresh berries in flat layers on a baking sheet, then transfer to bags for long-term storage. Or tincture in 50% alcohol.
Calendula (Calendula officinalis)
Calendula blooms all summer long and rewards frequent harvesting — the more you pick, the more it produces. Harvest the fully open flower heads in the morning when the resin is highest. You'll feel the stickiness on your fingers; that's the medicine.
What I use it for: Infused oils for salves and skin care, wound healing, lymphatic support, and gentle digestive teas.
How to preserve it: Spread petals on a drying screen in a single layer. They take longer than leafy herbs — up to two weeks — because of their moisture content. They're ready when they crinkle completely and no longer feel soft in the center.
Tulsi / Holy Basil (Ocimum tenuiflorum)
Tulsi is a sacred plant in Ayurvedic tradition and one of my personal favorites in the apothecary. It thrives in the Georgia heat and produces abundantly through late summer. Harvest the flowering tops before the flowers fully open for the highest aromatic content.
What I use it for: Adaptogenic support, stress resilience, clarity, and daily wellness teas. Tulsi has a warming, spicy quality that pairs beautifully with lemon balm and rose.
How to preserve it: Dry quickly in a warm space — tulsi can mold if dried too slowly. Or make a fresh plant tincture in 95% alcohol to capture the full aromatic profile.
Mugwort (Artemisia vulgaris)
Mugwort is a plant of the liminal — it grows at edges, roadsides, and forgotten places. Late summer is when the leaves are most potent before the plant puts energy into seed. Harvest the silvery-backed leaves and upper stems.
What I use it for: Dream work, smudge bundles, digestive bitters, and women's wellness preparations. Mugwort has a long history of use in both Western and Eastern herbal traditions.
How to preserve it: Bundle and hang to dry, or dry flat on screens. The silvery underside of the leaves is beautiful when dried — I often use mugwort in botanical arrangements alongside the medicine.
A Few Harvesting Principles I Always Return To
Harvest with gratitude. Before I take from any plant, I pause and acknowledge what it's offering. This isn't just spiritual practice — it slows me down enough to observe the plant carefully.
Never take more than a third. Leave plenty for the plant to continue growing, for wildlife, and for the seeds to mature and spread.
Harvest in the morning. After the dew has dried but before the afternoon heat, volatile oils are at their peak.
Know what you're picking. Positive identification is non-negotiable. If you're new to wildcrafting, start with plants you're growing yourself before venturing into the wild.
Building Your Apothecary One Season at a Time
You don't need to harvest everything at once. The herbal year is a rhythm — spring greens, summer flowers and leaves, autumn roots and berries, winter rest. Each season asks something different of us.
Start with one or two plants this August. Learn them well. Dry them, smell them, taste them, work with them. That relationship — built slowly over seasons — is the foundation of real herbal knowledge.
The plants are generous. They're ready when you are.
