Herbs are some of the most rewarding plants to grow, providing fresh flavors, medicinal benefits, and aromatic uses. Proper harvesting ensures maximum flavor and ongoing plant production throughout the growing season.

This guide will cover:
When and how to harvest different types of herbs
Whether the herb plant will keep producing
How to clean and store fresh and dried herbs


1. General Herb Harvesting Guidelines

Harvest in the morning – Oils are most concentrated after the dew has dried but before the heat of the day.
Use sharp scissors or pruners – Prevents plant damage and ensures a clean cut.
Harvest before flowering – Most herbs taste best before they bloom.
Never harvest more than ⅓ of the plant at a time – Allows for continuous regrowth.
Frequent harvesting promotes more growth – The more you cut, the bushier the plant becomes.


2. Herb Harvesting Guide by Type

Different herbs require specific harvesting techniques to maximize yield and longevity.


A. Leafy Herbs (Basil, Mint, Oregano, Thyme, Cilantro, Parsley, Dill)

These herbs are grown for their leaves and need frequent harvesting to prevent bolting (flowering).

Herb When to Harvest Will It Keep Producing? Harvesting Method
Basil 🌿 When plant has at least 6-8 leaves; before flowering Yes, if flowers are removed Pinch off leaves or cut stems ¼ inch above a node
Mint 🍃 Once plant is 6 inches tall Yes, aggressively spreading Cut stems just above a node
Oregano When stems are 4-6 inches long Yes, but remove flowers for best flavor Snip stems above a leaf node
Thyme Before or during flowering for best flavor Yes, cut frequently Cut entire sprigs ⅓ of the way down
Cilantro Before flowering; leaves should be bright green No, bolts quickly Snip individual stems near the base
Parsley 🌿 When leaves are large and vibrant Yes, cut-and-come-again Cut outer stems near the soil level
Dill (for leaves) Before flowering for best taste No, bolting stops leaf production Snip leaves near the base

Storage Tips for Leafy Herbs

  • Short-Term: Store fresh herbs in a glass of water (like cut flowers) or in the fridge wrapped in damp paper towels.
  • Long-Term: Dry by hanging upside down in a dark, well-ventilated space or freeze in ice cube trays with water or oil.

B. Woody Stem Herbs (Rosemary, Sage, Lavender, Marjoram)

These herbs develop woody stems and need different pruning techniques.

Herb When to Harvest Will It Keep Producing? Harvesting Method
Rosemary 🌿 Anytime, but best before flowering Yes, evergreen in warm climates Cut stems just above woody growth
Sage 🌿 Before or during early flowering Yes, but needs trimming Snip leaves or cut stems ¼ above a node
Lavender Just before flowers fully open Yes, but slows after flowering Cut stems above the woody base
Marjoram Before flowering for the best taste Yes, if cut frequently Cut entire stems to encourage bushiness

Storage Tips for Woody Herbs

  • Best preserved by drying—hang sprigs upside down in a cool, dark place.
  • Store dried leaves in an airtight container away from light and heat.

C. Flowering Herbs (Chamomile, Calendula, Borage, Chives)

These herbs are harvested for their flowers rather than their leaves.

Herb When to Harvest Will It Keep Producing? Harvesting Method
Chamomile 🌼 When flowers fully open Yes, regular picking encourages more blooms Pinch off flower heads
Calendula 🌸 When petals fully spread Yes, continuous bloomer Snip flowers at the base
Borage 🌿 When flowers are fresh and vibrant Yes, self-seeding annual Pinch flowers gently
Chives (flowers) When blossoms are fully open Yes, cut back after flowering Snip at the base

Storage Tips for Flowering Herbs

  • Fresh Use: Store in the fridge in a breathable bag.
  • Drying: Spread flowers on a mesh screen in a shady, airy location.
  • Teas & Oils: Store dried flowers in a sealed jar away from light.

D. Seed-Producing Herbs (Dill, Coriander, Fennel, Mustard)

These herbs are grown for their seeds rather than leaves.

Herb When to Harvest Will It Keep Producing? Harvesting Method
Dill (for seeds) When seed heads turn brown No, annual Cut seed heads and dry upside down
Coriander (Cilantro Seeds) When seeds turn brown and dry No, annual Shake seeds off the plant
Fennel (for seeds) When seeds turn brown and dry No, but self-seeds Clip seed heads and dry upside down
Mustard When seed pods dry out No, but self-seeds Cut seed heads and shake seeds loose

Storage Tips for Seeds

  • Air-dry completely before storing.
  • Store in sealed glass jars in a cool, dark place.
  • Can be frozen for extended freshness.

3. Cleaning and Storing Herbs

Shake off dirt instead of washing if drying herbs – Moisture can cause mold.
If using fresh, wash gently and pat dry with a towel.
For fridge storage: Wrap in damp paper towels and store in an airtight container.
For drying: Hang herbs upside down in a dark, dry area with good airflow.
For freezing: Chop herbs and freeze in oil or water in ice cube trays.

Which Herbs Are Best Fresh vs. Dried?

  • Best Fresh: Basil, Chives, Cilantro, Parsley
  • Best Dried: Oregano, Thyme, Rosemary, Sage, Lavender

4. How to Maximize Herb Yield

🌱 Pinch off flowers to extend leaf production.
🌱 Cut stems frequently to prevent plants from becoming woody.
🌱 Harvest early and often – Young leaves have the best flavor.
🌱 Mulch around herbs to retain moisture and prevent weeds.
🌱 Prune properly – Avoid overharvesting woody-stemmed herbs.


Final Thoughts

Harvesting herbs at peak freshness ensures the best flavor, fragrance, and medicinal benefits. With proper techniques for cutting, cleaning, and storing, you can enjoy fresh herbs year-round! 🌿✨
