Nicotiana × sanderae 'Starmaker Lime' (Starmaker Lime Nicotiana) care

Light

Nicotiana × sanderae 'Starmaker Lime' needs sun on the leaves, not just bright ambient room light. Full sun to part shade. Full sun gives the fullest flowering and best branching, while light shade is tolerated and helps in hot-summer regions without sacrificing much bloom. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water nicotiana × sanderae 'starmaker lime' when the top 2-3 cm of soil is dry, roughly every 4-7 days. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Keep evenly moist; flowering tobacco wilts quickly when dry. Water at the base to keep foliage dry, and monitor containers closely as they dry faster than beds.

Soil and pot

Nicotiana × sanderae 'Starmaker Lime' grows best in fertile, moisture-retentive but well-drained soil or quality potting mix. Likes humus-rich, compost-amended loam or a free-draining container mix at a near-neutral pH. Reliable drainage prevents root and stem rot while still holding steady moisture. 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

Nicotiana × sanderae 'Starmaker Lime' sits happiest at around 40-65% humidity and 16-27°C (61-81°F). Prefers moderate humidity and stays lush where summers are not arid. In dry heat the foliage wilts and blooms fade faster, so keep soil moisture consistent. If you keep the room above 16 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 nicotiana × sanderae 'starmaker lime' sparingly. Feed every 2-4 weeks with a balanced liquid fertiliser during growth and flowering, or mix slow-release feed into the soil at planting. Container plants benefit from more frequent feeding to sustain the continuous Starmaker bloom. 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 nicotiana × sanderae 'starmaker lime' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Wilting when soil dries — Flowering tobacco droops fast in dry conditions. Keep soil evenly moist, mulch beds, and check containers daily during hot, sunny spells.
• Sticky foliage — Glandular hairs make leaves naturally tacky; this is normal and not a problem, though it can trap dust and small insects, which a gentle rinse removes.
• Aphids and tobacco budworm — Aphids gather on tips and budworms damage flowers and buds. Hose off or use insecticidal soap for aphids; hand-pick budworms during evening feeding.
• Powdery mildew and grey mould — Damp, crowded plantings encourage fungal disease. Space plants for airflow, avoid wetting foliage, and remove affected leaves promptly.

Propagation

From seed. Start indoors 6-8 weeks before the last frost; surface-sow the fine seed without covering, as light is required for germination at around 20-22°C over 1-3 weeks. Pinch young plants for bushiness and transplant after frost danger has passed. Being an F1 hybrid, saved seed will not come true. 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

Nicotiana × sanderae 'Starmaker Lime' is toxic to pets. ASPCA-listed as toxic to cats, dogs, and horses (the Nicotiana genus is listed as toxic). Like all flowering tobaccos, it contains nicotine and related pyridine and piperidine alkaloids (anabasine, nornicotine). Ingestion causes hyperexcitability then depression, vomiting, incoordination, rapid heart rate, and potentially paralysis or death. Keep away from pets and seek veterinary help immediately if eaten. 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.
