Bay laurel (sweet bay) care

Light

Bay laurel is a sun-lover and needs the brightest spot in the home to thrive. 6 hours of direct sun. 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 bay laurel weekly watering in pots. 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. Drought-tolerant in the ground; pots need regular water.

Soil and pot

Bay laurel grows best in free-draining loam. pH 6.0-7.5. 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

Bay laurel sits happiest at around 40-70% (outdoor) humidity and 13-26°C (55-80°F). Outdoor humidity rarely matters. If you keep the room above 13 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 bay laurel sparingly. Balanced feed monthly in pots during growing season. 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 bay laurel in the Growli community. Each is annotated with the most common cause so you know where to start.

• Yellow leaves — Overwatering or magnesium deficiency.
• Bay sucker (Trioza alacris) — Curled yellowed leaf edges; cut off affected leaves.
• Winter cold damage — Browning leaves after frost; wait and trim damaged growth in spring.
• Slow growth — Normal; bays add 15-30 cm a year.
• Scale insects — Brown bumps on stems; treat with horticultural oil.

Companion plants

Bay laurel pairs well with Rosemary, Sage, and Thyme. These are species with similar light and water needs, so you can grow them in the same bed or container without conflict.

Propagation

Semi-ripe cuttings in summer root slowly under mist. 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

Bay laurel is mildly toxic to pets. ASPCA lists Laurus nobilis as toxic to cats and dogs due to eugenol and other essential oils. Large ingestions cause vomiting and diarrhoea; tough leathery leaves rarely tempt pets. 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.
