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.

Mature size: Around 25-40 cm tall and 25-35 cm wide; a dwarf, container-friendly hybrid far more compact than tall species nicotianas.

How to tell nicotiana × sanderae 'starmaker lime' needs repotting

Repotting on a calendar is less reliable than reading the plant. For nicotiana × sanderae 'starmaker lime', watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot nicotiana × sanderae 'starmaker lime' on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot nicotiana × sanderae 'starmaker lime'

Pot on seedlings as they grow; not a perennial repot. Nicotiana × sanderae 'Starmaker Lime'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Compact, well-branched bedding annual forming a neat mound of sticky, hairy foliage topped with abundant outward- and upward-facing star-shaped flowers..

What size pot to step nicotiana × sanderae 'starmaker lime' up to

Pot nicotiana × sanderae 'starmaker lime' on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot nicotiana × sanderae 'starmaker lime'

Pot nicotiana × sanderae 'starmaker lime' on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting nicotiana × sanderae 'starmaker lime'

Pot on before it is root-bound. Check nicotiana × sanderae 'starmaker lime' regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh fertile, moisture-retentive but well-drained soil or quality potting mix at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water nicotiana × sanderae 'starmaker lime' in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for nicotiana × sanderae 'starmaker lime'

Nicotiana × sanderae 'Starmaker Lime' wants 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. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting nicotiana × sanderae 'starmaker lime' — frequently asked questions

How often should you repot nicotiana × sanderae 'starmaker lime'?

Pot on seedlings as they grow; not a perennial repot for nicotiana × sanderae 'starmaker lime'. Nicotiana × sanderae 'Starmaker Lime' is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into fertile, moisture-retentive but well-drained soil or quality potting mix so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does nicotiana × sanderae 'starmaker lime' need?

When is the best time of year to repot nicotiana × sanderae 'starmaker lime'?

Can you put nicotiana × sanderae 'starmaker lime' straight into a much bigger pot?

No. Even a fast-growing nicotiana × sanderae 'starmaker lime' should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise nicotiana × sanderae 'starmaker lime' after repotting?

Not immediately. Wait about 1 week after repotting nicotiana × sanderae 'starmaker lime'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
