Seedling
2-4 weeksSmall plants with 2-4 leaves emerging from seed, tender and delicate
Keep soil consistently moist but not waterlogged. Provide bright light (12-16 hours if indoors). Thin seedlings to proper spacing once true leaves appear.
Vegetative Growth
3-8 weeksPlant develops multiple leaves and stems, establishing a bushy structure with increasing foliage
Pinch back growing tips to encourage bushiness. Maintain consistent moisture and provide full sun. Apply balanced fertilizer every 3-4 weeks.
Establishment
4-12 weeksPlant becomes robust with well-developed root system and substantial leaf production
Begin harvesting outer leaves regularly to promote bushiness. Reduce fertilizer frequency. Ensure good air circulation to prevent disease.
Flowering
2-6 weeksPlant produces flower buds and blooms; foliage may become less tender and flavor may concentrate
Pinch off flower buds if tender leaves are desired. Allow flowers to develop if seeds are desired. Flowering reduces leaf quality in some herbs.
Maturity/Harvest Ready
Until frost or plant declinePlant is fully developed with abundant foliage or seeds ready for collection
Continue regular harvesting to extend productivity. Deadhead spent flowers unless collecting seeds. Some herbs decline after flowering; plan for succession planting.

Uses
Fresh cooking and flavoring
CulinaryMost herbs are used fresh in cooking to add flavor, aroma, and color to dishes. They can be added at different cooking stages: hardy herbs (rosemary, thyme) during cooking; tender herbs (basil, cilantro, dill) at the end or as garnish. [source]
Drying and preservation
CulinaryMany herbs dry well for year-round storage and use. Dried herbs are more concentrated in flavor and work well in sauces, teas, spice blends, and long-cooking dishes. [source]
Herbal teas and infusions
MedicinalCulinary and medicinal herbs are steeped in hot water to create soothing teas that support health and digestion. Common tea herbs include chamomile, peppermint, sage, and ginger. [source]
Traditional and folk remedies
MedicinalMany herbs have been used for centuries in traditional medicine to support health, boost immunity, aid digestion, and reduce inflammation. Examples include ginger, turmeric, echinacea, and elderberry. [source]
Aromatics and fragrance
HouseholdDried herbs and herb-infused products provide natural fragrance for homes. Lavender, mint, and rosemary are popular for sachets, potpourri, and essential oil applications. [source]
Crafting and decorative purposes

Harvest Tips
Most herbs produce best with regular harvesting of outer leaves and stems. Begin pinching leaves once plant has 6-8 leaves; never remove more than 1/3 of plant at once. Harvest in morning after dew dries for best flavor and oil content. Cut stems above leaf nodes to encourage branching. Many herbs are best harvested just before flowering for peak flavor. Tender herbs (basil, cilantro) are harvested continuously; woody herbs (rosemary, thyme) can be pruned more aggressively.
