Care at a glance
Light
Aim for at least 4-6 hours of direct sun on the leaves. Demands full sun, 6-8 hours daily, for strong upright stems and concentrated fragrance. In poor light it grows sparse, soft and prone to disease. If your only bright window faces south, that's perfect for barbecue rosemary — same window any aroid would fry on.
Watering
Watering barbecue rosemary: when the top 4-5 cm of soil is dry, roughly every 10-14 days. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Drought-tolerant once rooted. Water deeply but infrequently and let soil dry well; overwatering is the leading cause of rosemary decline. Minimal water in winter.
Soil and pot
Barbecue Rosemary grows best in sandy, gritty, well-drained neutral to alkaline soil. Sharp drainage is critical; amend with sand or grit. Rosemary hates wet roots and heavy clay, so raised beds or terracotta pots help excess water escape. 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
Barbecue Rosemary sits happiest at around 30-50% humidity and 15-29°C (59-84°F). Prefers dry air and good airflow. High humidity with crowding promotes powdery mildew and root issues; space plants for ventilation. 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 barbecue rosemary sparingly. Light feeder. A single balanced or low-nitrogen feed in spring is sufficient; over-feeding gives soft, floppy stems with diluted aroma. Lean soil yields tougher, tastier 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 barbecue rosemary in the Growli community. Each is annotated with the most common cause so you know where to start.
- Root rot — Wet, heavy soil rots the roots and yellows the plant. Use gritty, free-draining soil and water only when dry, especially in winter.
- Powdery mildew — White coating appears in humid, crowded growth. Increase spacing and airflow and avoid overhead watering.
- Winter cold damage — Hard frost browns or kills stems. Mulch the base, choose a sheltered spot, or pot up and shelter in cold regions.
- Woody, bare base — Old plants get leggy and sparse below. Trim lightly after flowering, never into bare old wood, to keep it bushy.
Propagation
Propagate from semi-ripe stem cuttings in summer, which root readily in gritty mix, or by layering low branches. Cuttings keep the cultivar's upright skewer habit true to type. 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
Barbecue Rosemary is pet-safe. ASPCA-listed as non-toxic to cats, dogs and horses. Rosemary (Salvia rosmarinus, formerly Rosmarinus officinalis) is classified non-toxic; fresh or dried sprigs are safe if nibbled, though concentrated rosemary essential oil should never be given to 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.
Barbecue Rosemary care — frequently asked questions
What is Barbecue Rosemary?
Barbecue Rosemary (Salvia rosmarinus 'Barbecue') is a culinary herb with a vigorous, strongly upright evergreen shrub with stiff, tall, straight stems and narrow resinous needle-like leaves, more vertical than typical rosemary. growth habit, reaching 120-180 cm tall, 60-90 cm wide at maturity. Barbecue Rosemary is an upright rosemary cultivar bred for long, straight, sturdy stems that strip clean to make natural skewers for grilling. Aromatic and resinous, it is a sun-loving Mediterranean evergreen wanting sharp drainage and dry conditions, and it tolerates drought once established while resenting wet, heavy soil.
How much light does barbecue rosemary need?
Barbecue Rosemary grows best in direct sun (at least 4-6 hours). Demands full sun, 6-8 hours daily, for strong upright stems and concentrated fragrance. In poor light it grows sparse, soft and prone to disease.
How often should I water barbecue rosemary?
Water barbecue rosemary when the top 4-5 cm of soil is dry, roughly every 10-14 days. Drought-tolerant once rooted. Water deeply but infrequently and let soil dry well; overwatering is the leading cause of rosemary decline. Minimal water in winter. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.
Is barbecue rosemary toxic to cats and dogs?
Barbecue Rosemary is pet-safe. ASPCA-listed as non-toxic to cats, dogs and horses. Rosemary (Salvia rosmarinus, formerly Rosmarinus officinalis) is classified non-toxic; fresh or dried sprigs are safe if nibbled, though concentrated rosemary essential oil should never be given to pets.
What USDA hardiness zone does barbecue rosemary grow in?
Barbecue Rosemary is rated for USDA zone 7-10 (evergreen perennial; protect in colder zones) and RHS hardiness H4. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
