Begin pinching back tips to encourage bushiness; reduce watering frequency; apply balanced fertilizer every 3-4 weeks
Flowering

Deadhead spent flowers to extend leaf production; harvest leaves before heavy flowering for best culinary flavor
Active Harvesting

Never remove more than 1/3 of the plant at once; harvest in morning after dew dries; deadhead flowers if leaf flavor is priority
Dormancy/Winter
4-6 months depending on zoneCold-hardy perennials die back; tender annuals must be replaced or brought indoors

Harvest Tips
Begin harvesting leaves once plants establish (4-6 weeks). Pick leaves in morning after dew dries for best flavor and oil content. Remove no more than 1/3 of plant at once to maintain vigor. Pinch off flower buds on culinary herb borders to extend leaf production. Most herbs are best harvested before flowering for maximum flavor concentration.
Fun Facts

- 🌱 The practice of companion planting with herbs dates back thousands of years; ancient Romans planted herb borders around vegetables to improve soil fertility and deter pests.
- 🌱 Many culinary herbs contain volatile oils whose concentration is highest just before flowering, which is why experienced gardeners harvest in early morning on sunny days.
