About Nicotiana × sanderae 'Starmaker Lime'
Nicotiana × sanderae 'Starmaker Lime' · also called Starmaker Lime Nicotiana, Lime-green Flowering Tobacco · flowering
A compact bedding flowering tobacco bearing masses of upward-facing, star-shaped flowers in a fresh lime-green that pairs with almost any colour scheme. From the well-branched Starmaker series, 'Starmaker Lime' is bred for tidy mounds, weather tolerance, and non-stop bloom in beds and containers. It performs in sun to part shade and draws pollinators through summer.
Growth habit: Compact, well-branched bedding annual forming a neat mound of sticky, hairy foliage topped with abundant outward- and upward-facing star-shaped flowers.
Watch for — 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.
What fertiliser nicotiana × sanderae 'starmaker lime' actually wants — and why
Nicotiana × sanderae 'Starmaker Lime' is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for nicotiana × sanderae 'starmaker lime': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed nicotiana × sanderae 'starmaker lime', and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For nicotiana × sanderae 'starmaker lime':
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. Treat that as every 2-4 weeks between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when nicotiana × sanderae 'starmaker lime' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for nicotiana × sanderae 'starmaker lime'
Half strength is the safe default for nicotiana × sanderae 'starmaker lime' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water nicotiana × sanderae 'starmaker lime' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the nicotiana × sanderae 'starmaker lime' watering schedule.
Signs you are over-feeding nicotiana × sanderae 'starmaker lime'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for nicotiana × sanderae 'starmaker lime':
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding nicotiana × sanderae 'starmaker lime'
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full nicotiana × sanderae 'starmaker lime' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of nicotiana × sanderae 'starmaker lime' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for nicotiana × sanderae 'starmaker lime'
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
