Herbs are the highest-value square foot in the garden. A few dollars of plants replace a steady stream of expensive grocery-store clamshells, most herbs thrive in a pot by the kitchen door, and they ask for almost nothing. Basil is the gateway herb, so we'll lead with it, then cover the rest.

Basil: warmth, and pinch relentlessly

Basil is a true heat-lover: it sulks and blackens in cold, so wait until nights are reliably above 50°F, well past your last frost date, before it goes outside. Give it full sun, steady moisture, and then the one trick that matters: pinch constantly. Every time you snip the top of a stem just above a pair of leaves, the plant branches into two, growing bushier and more productive. Left unpinched, basil races to flower, and once it flowers the leaves turn bitter and growth slows — so pinch out flower buds the moment you see them. The herb famously pairs with tomatoes in the kitchen and the bed alike (see companion planting).

Basil timing, from seed to bed

The catalog numbers make basil's schedule simple. Start seeds indoors 4 to 6 weeks before you intend to plant out, and plan on transplanting one to two weeks after your last frost, once the soil and nights have genuinely warmed. Basil is damaged below about 40°F — not just frost but plain cold — so err late, and give it a full 10 to 14 days of hardening off, longer than most transplants, because those tender leaves burn easily in sudden sun and wind. Space plants about 6 inches apart for steady pinching (four per square in a square-foot bed), or up to 12 inches if you want big bushy individuals. A second sowing in early summer, about three weeks after the first, keeps young productive plants coming when the first round tires — basil responds well to succession planting right up to midsummer.

Beyond sweet basil

One packet rack holds a world of basil types, all grown the same way. Genovese-type sweet basil is the pesto workhorse. Thai basil holds its anise-clove flavor through cooking, which sweet basil doesn't. Lemon basil and lime basil bring genuine citrus scent for fish and teas, and holy basil (tulsi) is the peppery, sacred herb of Thai and Indian cooking. Compact small-leaf types make tidy edging and take to pots especially well. Plant two or three types and you'll find they earn their space differently in the kitchen.

A starter herb garden that earns its keep

If you're choosing a first lineup, this five-pot kitchen garden covers most cooking:

Add dill if you pickle, and mint (in its own pot) if you drink tea. Every one of these is easier than the average vegetable.

The two herb families

Most kitchen herbs fall into two camps that want opposite things.

• Mediterranean herbs (rosemary, thyme, oregano, sage) evolved on dry, sunny hillsides. They want full sun, lean soil, and to dry out between waterings. The fastest way to kill them is rich soil and overwatering. They're tough perennials in mild climates.
• Tender, leafy herbs (basil, cilantro, dill, parsley) want richer soil, more water, and frequent harvesting. Most are annuals that bolt to seed in heat.

A few useful perennials sit outside both camps: chives are an unkillable clumping onion relative happy in ordinary moist soil, and mint is so vigorous it should live in a pot forever, never open ground.

Cilantro and dill bolt — plan for it

Cilantro is the classic frustration: it bolts to seed almost overnight in summer heat, the leaves turning ferny and the plant flowering before you've used much. Bolting isn't a sign you did anything wrong. Treat cilantro and dill as cool-season crops, sow a fresh pinch every few weeks (succession planting), and let some flower to feed pollinators and self-sow. Why heat-driven bolting happens is covered in why vegetables bolt. Both have taproots and resent moving, so direct-sow them — full instructions in the cilantro and dill guides.

Soil, water, and feeding

For the tender leafy camp, prepare soil as you would for lettuce: compost-enriched, moisture-retentive, watered before it dries out. Basil in particular grows lush with steady moisture and a monthly light feed — but stop short of heavy fertilizer, which produces big, bland leaves with less oil. For the Mediterranean camp, do nearly the opposite: no fertilizer, sharp drainage (add coarse grit to heavy ground, or grow in pots), and water only when the soil is dry an inch down. If your garden is clay, grow rosemary and thyme in containers rather than fighting the drainage.

The short trouble list

Herbs mostly look after themselves, but three problems are worth knowing. Basil downy mildew is the serious one — yellowing between leaf veins with gray fuzz beneath, arriving in warm humid weather; space plants for airflow, water at the base in the morning, and harvest hard when you see it, since it spreads fast (see the downy mildew guide). Aphids cluster on soft new tips of basil and parsley, and a hard spray of water plus the beneficial insects that flowering herbs attract usually settles them. Slugs shred young basil in damp springs. And in midsummer, Japanese beetles will skeletonize basil leaves in some regions — handpick in the morning. Fat green caterpillars on parsley or dill are swallowtail young; spare them if you can.

Harvesting is the maintenance

With herbs, picking is the care, as regular harvesting keeps plants bushy and delays flowering. Take from the top, never more than a third at once, and harvest in the morning when oils are highest. Most herbs grow happily in containers, which also lets you give Mediterranean types the sharp drainage they crave and pull tender ones indoors before frost. A 6- to 8-inch pot suits a single basil or parsley; give rosemary and sage something closer to a gallon. Indoors over winter, a south window keeps chives, parsley, and a potted rosemary ticking along, though basil really needs a grow light to amount to much — see container gardening basics for mix and drainage.

For storage, match the method to the herb. Basil hates the refrigerator (the leaves blacken) — stand cut stems in a glass of water on the counter like flowers, or turn a big harvest straight into pesto and freeze it in cubes. Tender herbs like cilantro, dill, and parsley keep a week or more wrapped loosely in the fridge, and freeze better than they dry. The Mediterranean herbs are the ones that dry beautifully: hang small bundles somewhere airy and dark, then strip the leaves into jars. However you preserve them, cut generously in late summer — a frost will take the basil overnight, and it's a shame to lose it standing. Dial in your sowing dates on the planting calendar.
