The Herb Pruning Formula: When, Where & How Much to Cut

One Rule for All Herbs: Prune ⅓ Every 3 Weeks

Most gardeners under-prune. Regular cutting prevents woody stems, delays flowering, and maximizes leaf yield.

The Universal Schedule

1. Spring start: When new growth reaches 6–12 inches, cut ⅳ off the end of every stem. Spare no one.
2. Repeat every 3 weeks (or sooner if you harvest heavily). Never go more than 3 weeks without cutting—even if you don't need the herbs.
3. Use the surplus: Make herbal vinegar, freeze, give away, or dry for sachets (scented herbs in old stockings for drawers, closets, car).

Herb-Specific Nuances

• Basil: Must be pruned constantly. Pinch 3 leaf pairs below any flower bud to delay bolting.
• Cilantro: Cut flower stalk 2″ below bloom. Reseed every 2–3 weeks for continuous harvest.
• Woody perennials (rosemary, lavender, sage, thyme): Same ⅓/3-week rule. They respond with vigorous soft growth.

Why It Works

Pruning removes apical dominance, triggering lateral buds. The plant stays juvenile, leafy, and productive. Neglected herbs become woody, flower early, and decline.
