Gerbera Daisy (Barberton daisy) care

Light

Bright but filtered. Gerbera Daisy burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Wants lots of bright light to rebloom: morning sun with shade from intense afternoon heat outdoors, or a bright south/east window indoors. At least 6 hours of light daily; too little light gives leggy growth and few flowers. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering gerbera daisy: when the top 2-3 cm (1 in) of soil is dry, roughly 1-2 times per week in active growth. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Highly prone to crown and root rot, so let the soil surface dry between waterings and never let the pot sit in water. Water at the base early in the day, not over the foliage, and keep the crown dry to avoid fungal disease.

Soil and pot

Gerbera Daisy grows best in rich, well-drained potting mix or loam high in organic matter. Sharp drainage is essential — excess moisture around the crown causes rot. Use containers or raised beds for heavy soils. Plant with the crown slightly above the soil line so it stays dry. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Gerbera Daisy sits happiest at around 40-50% humidity and 16-21 C ideal; tolerates ~7-24 C, minimum ~7 C (60-70 F ideal; tolerates ~45-75 F, minimum ~45 F). Tolerates average household humidity. Avoid high humidity combined with poor airflow and wet leaves, which encourages powdery mildew and botrytis (grey mould); good ventilation matters more than misting. If you keep the room above 16 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed gerbera daisy sparingly. 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. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on gerbera daisy in the Growli community. Each is annotated with the most common cause so you know where to start.

• Crown and root rot — The most common and serious problem, caused by soggy soil and water-mould pathogens (Phytophthora, Pythium). Plant with the crown above soil level, water at the base, and ensure sharp drainage.
• Powdery mildew — White powdery coating on leaves and stems, favoured by warm days, cool nights, high humidity, and poor airflow. Improve ventilation, avoid wetting foliage, and treat with a suitable fungicide or horticultural oil.
• Botrytis (grey mould) — Fuzzy grey mould on flowers and foliage in damp, still air. Remove faded blooms and dead leaves promptly and increase air circulation, particularly on plants grown under cover.
• Sap-sucking pests — Aphids, whitefly, thrips, and spider mites cluster on new growth and undersides of leaves. Treat with insecticidal soap or neem oil and check regularly, especially indoors and under glass.
• 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.
• Yellowing between leaf veins — Interveinal chlorosis from iron/manganese deficiency, common in pots. Use a fertiliser containing micronutrients and check that the soil is not waterlogged or too alkaline.

Propagation

Propagate by division of established clumps in early spring, by basal or heel cuttings from side shoots in summer, or from seed sown at 18-22 C (germinates in about 2-3 weeks, sometimes longer). Division is the quickest route to flowering-size plants; named cultivars are best divided rather than grown from seed, which does not come true. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Gerbera Daisy is pet-safe. The ASPCA individually lists Gerbera jamesonii (Gerber Daisy) as non-toxic to dogs, non-toxic to cats, and non-toxic to horses. Do not confuse it with toxic look-alikes such as chrysanthemums (mums), which are toxic to pets. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
