Care at a glance

Light

Aim for at least 4-6 hours of direct sun on the leaves. Full sun to very bright light gives the most aromatic, compact growth and the best flowering. It tolerates a little shade but becomes lax and less fragrant in poor light. If your only bright window faces south, that's perfect for pelargonium 'lara starshine' — same window any aroid would fry on.

Watering

Watering pelargonium 'lara starshine': when the top 2-3 cm of compost is dry, roughly every 5-10 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, then let the surface dry before watering again; it dislikes constantly wet roots. Reduce sharply in winter, keeping the rootball just short of dry.

Soil and pot

Pelargonium 'Lara Starshine' grows best in free-draining, loam-based compost. John Innes No. 2 or a peat-free multipurpose mix with added perlite or grit suits it. Like all pelargoniums it needs sharp drainage rather than rich, moisture-retentive soil. 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 'Lara Starshine' sits happiest at around 30-50% humidity and 10-24°C (50-75°F). Prefers dry to average air with good airflow. Do not mist; the soft, divided foliage is prone to grey mould and rust in humid, stagnant conditions. 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 'lara starshine' sparingly. Feed every 2-3 weeks in spring and summer with a balanced liquid feed; scented-leaved types need only modest feeding, as too much nitrogen produces lush leaves at the expense of fragrance and flowers. Stop feeding in autumn and 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 'lara starshine' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Lax, weak-scented growthToo little light or over-feeding with nitrogen. Grow in full sun and feed sparingly to keep growth firm and aromatic; pinch tips to encourage bushiness.
  • Pelargonium rustBrown pustules in rings on leaf undersides. Remove affected leaves, improve airflow, and avoid wetting the foliage.
  • Botrytis (grey mould)Grey mould on soft foliage and spent flowers in damp, crowded conditions. Thin growth, deadhead, and ventilate well.
  • Overwatering / root rotSoggy compost yellows leaves and rots roots. Let the surface dry between waterings and use free-draining pots and mix.

Propagation

Take softwood or semi-ripe stem cuttings 8-10 cm long in spring or late summer; remove lower leaves, let the cut callus briefly, and root in gritty, just-moist compost in good light. Scented pelargoniums root readily in a few weeks without hormone. 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 'Lara Starshine' is toxic to pets. The ASPCA lists Pelargonium species (geranium), which includes scented-leaved pelargoniums, as toxic to cats, dogs, and horses. The toxic principles are geraniol and linalool, and ingestion can cause vomiting, anorexia, depression, and dermatitis. Although the leaves are used to flavour culinary preparations for people, keep the plant out of reach of 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.

Water pelargonium 'lara starshine' when the top 2-3 cm of compost is dry, roughly every 5-10 days in growth. Water thoroughly, then let the surface dry before watering again; it dislikes constantly wet roots. Reduce sharply in winter, keeping the rootball just short of dry. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is pelargonium 'lara starshine' toxic to cats and dogs?

Pelargonium 'Lara Starshine' is toxic to pets. The ASPCA lists Pelargonium species (geranium), which includes scented-leaved pelargoniums, as toxic to cats, dogs, and horses.
