About Gerbera Daisy
Gerbera jamesonii · also called Gerbera daisy, Barberton daisy · flowering
Gerbera jamesonii is a clump-forming flowering perennial from South Africa, prized for big, bold, daisy-like blooms in jewel tones on tall leafless stems. Give it bright light, well-drained soil, and careful watering that keeps the crown dry. The ASPCA lists it as non-toxic to dogs, cats, and horses.
Growth habit: Clump-forming herbaceous perennial. Forms a low rosette of lobed, slightly hairy leaves, with large solitary daisy flowers held well above the foliage on long, leafless stems.
Watch for — Few flowers / leggy growth: Usually too little light. Move to a brighter spot, deadhead spent blooms to encourage more, and feed during the growing season.
What fertiliser gerbera daisy actually wants — and why
Gerbera Daisy 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 gerbera daisy: 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 gerbera daisy, 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 gerbera daisy:
Feed during the growing season with a balanced controlled-release fertiliser 2-3 times, or a liquid feed every two weeks. Choose a formula with micronutrients including iron and manganese, especially for container plants, as gerberas are prone to interveinal chlorosis without them. Ease off in winter. 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 gerbera daisy 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 gerbera daisy
Half strength is the safe default for gerbera daisy — 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 gerbera daisy first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the gerbera daisy watering schedule.
Signs you are over-feeding gerbera daisy
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for gerbera daisy:
- 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 gerbera daisy
- 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 gerbera daisy care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of gerbera daisy 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 gerbera daisy
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.
Fertilising gerbera daisy — frequently asked questions
What fertiliser does gerbera daisy need?
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. Gerbera Daisy is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
How often should I feed gerbera daisy?

Choose a formula with micronutrients including iron and manganese, especially for container plants, as gerberas are prone to interveinal chlorosis without them. Ease off in winter.

What does over-feeding gerbera daisy look like?
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. Feeding gerbera daisy year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of gerbera daisy?
Flush the pot of gerbera daisy 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.
