How to plant
Consult species-specific guidance. Most benefit from good drainage, patience, and matching zone.
Grower's tip
Mediterranean evergreen — aromatic leaves, white flowers, blue-black berries. Culinary and symbolic.
Soil preferences
Light, well-drained loam. Most culinary herbs suffer in soggy soil.
6.0–7.5 (neutral)
A single fork of finished compost at planting is plenty — over-feeding weakens flavor.
Watering
Consistent moisture while young; let the top inch dry between waterings once established.
Water at the base in the morning to keep leaves dry and prevent mildew.
Overwatered: yellow lower leaves, damp-smelling soil, wilt that doesn't rebound. Underwatered: crispy tips, purple stems, sudden bolting.
Prefers top-watering — Trees are always top-watered — deep slow soak at the drip line, never at the trunk. Bottom-watering only makes sense for nursery seedlings.
Temperature tolerance
65–85°F (18–29°C) ideal
55–65°F (13–18°C)
Most annual herbs are frost-tender; perennial herbs (sage, thyme, oregano, mint) tolerate frost once established.
Container growing
Yes — great in containers
6–10 in (15–25 cm) wide, minimum 6 in deep
Herbs thrive in pots — group by water needs (Mediterranean herbs on the drier side, basil/parsley/cilantro on the wetter).
Succession planting
Sow leafy herbs (basil, cilantro, dill, parsley) every 3–4 weeks for a steady supply.
Detailed harvesting
Pinch or snip stems just above a leaf pair — never strip a plant of more than one third at a time. Harvest before flowering for peak flavor.
Post-harvest storage & preservation
Air-dry small bundles upside-down in a dark airy spot, or freeze chopped in olive oil in ice-cube trays. Store dried leaves whole in a jar; crush just before use.
Culinary, medicinal & other uses
Culinary flavoring — fresh in salads and finishing, dried in slow cooks and rubs. Many herbs (basil, mint, chamomile) also infuse oils, vinegars, or teas.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Mostly insect-pollinated; some (basil, mint) self-pollinate.
Isolate different varieties of the same species by 150 ft or cage/bag flower heads to keep strains true.
Let one plant flower fully; harvest brown, dry seed heads into a paper bag; rub free and store dry.

From your kitchen — grow common myrtle from what you already have
Most annual and biennial herbs give seed if you stop harvesting one plant and let it flower.
- 1Choose your best-flavored, latest-to-bolt plant to be the seed parent.
- 2Let it flower, then wait for the seed heads to dry brown and papery on the plant.
- 3Cut whole stems into a paper bag before they shatter.
- 4Rub or crumble the heads to release seed; sieve out the chaff and store dry in an envelope.
Storage: Most herb seed stays viable 2–4 years dry.
