Pelargonium x domesticum 'Hazel Carey' (Hazel Carey regal pelargonium) care

Light

Bright but filtered. Pelargonium x domesticum 'Hazel Carey' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright light plus gentle morning sun brings out the petal markings and full trusses; protect from harsh midday summer sun, which scorches leaves and shortens flowering. 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 pelargonium x domesticum 'hazel carey': when the top 2-3 cm of soil is dry, about every 5-7 days in 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. Water thoroughly, let the surface dry, then repeat; cut back after flowering and keep almost dry in winter. Water at the base to keep the dense foliage dry.

Soil and pot

Pelargonium x domesticum 'Hazel Carey' grows best in free-draining loam-based potting mix. John Innes No. 2 with grit supplies steady drainage and weight. Avoid moisture-retentive composts that invite black-leg. Neutral to slightly alkaline pH suits it. 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

Pelargonium x domesticum 'Hazel Carey' sits happiest at around 30-50% humidity and 10-21°C (50-70°F). Average to dry air is fine; airflow is the key concern, since still, humid conditions promote botrytis and rust on the bushy crown. If you keep the room above 10 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 pelargonium x domesticum 'hazel carey' sparingly. Apply a balanced liquid feed every 1-2 weeks in spring, moving to high-potash as buds form; stop feeding once flowering finishes and through 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 pelargonium x domesticum 'hazel carey' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Single short flush — Regals flower mainly in spring; a cool winter rest at 7-10°C and bright spring light support the strongest display.
• Pelargonium rust — Concentric brown pustules under the leaves spread in humid air; remove infected foliage and ventilate well.
• Botrytis — Grey mould on fading flowers and crowded leaves in damp conditions; deadhead and keep the plant airy.
• Whitefly — A persistent glasshouse pest weakening growth with honeydew; treat with insecticidal soap or Encarsia parasites.

Propagation

Root 8-10 cm semi-ripe cuttings from non-flowering shoots in late summer. Remove the lower leaves, let the cut callus, and insert into gritty, just-moist compost at about 18°C; rooting takes 3-4 weeks. 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

Pelargonium x domesticum 'Hazel Carey' is toxic to pets. The ASPCA classifies Pelargonium species (geranium) as toxic to cats, dogs and horses. Toxic principles are geraniol and linalool; ingestion can cause vomiting, anorexia, depression and dermatitis. Keep this plant out of pets' reach. 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.
