About Pelargonium 'Prince of Orange'

Pelargonium 'Prince of Orange' · also called Orange-scented pelargonium, Prince of Orange geranium · herb

'Prince of Orange' is a compact scented-leaf pelargonium whose small, crinkled green leaves release a bright, sweet orange fragrance when touched. It carries dainty pale mauve-pink flowers and makes a tidy windowsill or patio herb. Like all pelargoniums it wants bright light, sharp drainage, warmth and protection from frost.

Growth habit: Bushy, upright and relatively compact scented-leaf type; responds well to pinching, which keeps it dense and well-furnished with aromatic foliage.

Watch for — Few flowers or weak scent: Insufficient light reduces both blooming and fragrance; move to a sunnier position and feed with high-potash fertiliser.

What fertiliser pelargonium 'prince of orange' actually wants — and why

Pelargonium 'Prince of Orange' is a soft, fast leafy herb that you harvest hard — a modest balanced feed keeps tender growth coming without tipping it into bland or bolting.

A balanced general feed (even N-P-K) at modest strength — enough nitrogen to keep replacing the leaves you pick, but not so much that flavour thins or it bolts to seed.

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 pelargonium 'prince of orange': 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 pelargonium 'prince of orange', 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 pelargonium 'prince of orange':

Feed fortnightly in spring and summer with a balanced liquid feed at half strength, or high-potash feed to encourage flowers. Pause feeding through autumn and winter. In practice: a balanced liquid feed every few weeks through the main growing and harvesting season (spring through early autumn), more often the harder you are picking it.

The dormant-season rule matters more than the exact interval: skip feeding entirely when pelargonium 'prince of orange' 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 pelargonium 'prince of orange'

Half strength is a sensible default for pelargonium 'prince of orange' — enough to fuel regrowth after cutting, gentle enough that the leaves stay aromatic rather than watery.

Feeding always goes onto already-damp soil, never dry roots — water pelargonium 'prince of orange' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the pelargonium 'prince of orange' watering schedule.

Signs you are over-feeding pelargonium 'prince of orange'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for pelargonium 'prince of orange':

Fast, soft, pale growth with diluted, less aromatic flavour.
Early bolting (running to flower) and a bitter edge.
Salt crust and scorched tips on container plants.

Signs you are under-feeding pelargonium 'prince of orange'

Pale, slow regrowth after cutting and small leaves.
A tired, stalled plant that cannot keep up with harvesting.
Yellowing older leaves in a long-spent pot.

If the symptoms point at watering, light or roots rather than nutrition, the full pelargonium 'prince of orange' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Pot-grown pelargonium 'prince of orange' builds up feed salts quickly — water until it drains each time and flush the pot with plain water every few weeks, especially on a sunny windowsill.

Organic vs synthetic feeds for pelargonium 'prince of orange'

Organic options

A diluted seaweed feed or worm-casting tea keeps soft growth coming without overdoing it. UK: dilute seaweed or Westland; US: Espoma Garden-tone or Neptune's Harvest. Gentle, hard to overdo, flavour-friendly.

Synthetic / liquid feeds

A balanced liquid feed at half strength through harvesting — UK: Phostrogen, Baby Bio or Westland; US: Miracle-Gro all-purpose at half strength. Fast regrowth; just do not overdo the nitrogen.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
