Herb garden (kitchen herbs) care

mixed culinary herbs

Also called kitchen herbs, culinary herb garden.

Light

Herb garden is a sun-lover and needs the brightest spot in the home to thrive. 6+ hours of direct sun for most culinary herbs; parsley and mint tolerate a little less. Indoors that almost always means a south or west-facing windowsill in the northern hemisphere. Plants moved abruptly from low light to direct sun will scorch — acclimate them over 7-10 days by giving a little more sun each day.

Watering

Water herb garden depends on the herb. The actual day count varies with pot size, light level, and the season — the finger test (or, better, lifting the pot to feel its weight) is more reliable than a calendar. Empty any drainage saucer after watering so the pot is never sitting in water. Mediterranean herbs prefer dry, sandy soil with infrequent deep watering. Tender herbs need consistent moisture. Group by water need.

Soil and pot

Herb garden grows best in free-draining mix. Mediterranean herbs prefer lean, gritty soil; tender herbs prefer richer compost-amended mix. Containers let you give each its own conditions. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Herb garden sits happiest at around 40-60% (outdoor) humidity and 15-29°C (60-85°F). Most herbs prefer dry air; basil and parsley tolerate humidity. If you keep the room above 15 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed herb garden sparingly. Light feeding only — over-fed herbs lose flavour. A half-strength balanced feed every 4-6 weeks during growth. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on herb garden in the Growli community. Where a problem matches one of our diagnostic guides, click through for the full step-by-step recovery plan written for herb garden specifically.

Leggy herbs — Insufficient light or skipped pinching.
Bolting (flowering) — Heat or day length triggers flowering; pinch buds and replant.
Powdery mildew — Common on mint and sage in humid weather; improve airflow.
Aphids — Most common on basil and parsley; rinse off with water.

Companion plants

Herb garden pairs well with Tomato (basil), Strawberry (thyme), and Carrot (parsley). These are species with similar light and water needs, so you can grow them in the same bed or container without conflict.

Propagation

Mediterranean herbs root well from softwood cuttings; tender herbs are usually grown from seed. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Herb garden is pet-safe. Most culinary herbs are pet-safe (basil, parsley, dill, thyme, rosemary). Chives, onion, and garlic are toxic to cats and dogs. Check each herb individually. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
