About Leucanthemum × superbum 'Silver Princess'

Leucanthemum × superbum 'Silver Princess' · also called Silver Princess Shasta daisy, Silberprinzesschen daisy · flowering

'Silver Princess' is a dwarf, compact Shasta daisy smothered in classic white single daisies with bright yellow centres from early summer to autumn. At roughly 25-40 cm it suits border edges, containers and cut flowers. Long-flowering if deadheaded, it forms tidy mounds, asks only for sun and good drainage, and is among the freest-blooming of the dwarf selections.

Growth habit: Compact, mound-forming herbaceous perennial with a low rosette of toothed dark green leaves and short, sturdy stems carrying flowers just above the foliage.

What fertiliser leucanthemum × superbum 'silver princess' actually wants — and why

Leucanthemum × superbum 'Silver Princess' 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 leucanthemum × superbum 'silver princess': 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 leucanthemum × superbum 'silver princess', 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 leucanthemum × superbum 'silver princess':

Modest needs. Top-dress with compost or apply a balanced fertiliser in early spring, with an optional light feed after the first flush. Skip heavy nitrogen, which causes lax growth and fewer flowers on this compact selection. Treat that as sparingly through the growing season 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 leucanthemum × superbum 'silver princess' 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 leucanthemum × superbum 'silver princess'

Half strength is the safe default for leucanthemum × superbum 'silver princess' — 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 leucanthemum × superbum 'silver princess' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the leucanthemum × superbum 'silver princess' watering schedule.

Signs you are over-feeding leucanthemum × superbum 'silver princess'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for leucanthemum × superbum 'silver princess':

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 leucanthemum × superbum 'silver princess'

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 leucanthemum × superbum 'silver princess' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush the pot of leucanthemum × superbum 'silver princess' 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 leucanthemum × superbum 'silver princess'

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.
