Hydrangea 'Pinky Winky' (Pinky Winky hydrangea) care

Light

Most houseplants will scorch where hydrangea 'pinky winky' thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Full sun to part shade; 6+ hours of direct sun produce the strongest two-tone effect and most blooms. In hot regions afternoon shade reduces flower scorch. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.

Watering

Aim for when the top 5 cm of soil is dry, about 1-2 times per week for hydrangea 'pinky winky', but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Keep evenly moist while establishing and through bloom; about 2.5 cm (1 inch) of water weekly. Fairly drought-tolerant once established but flowers best with steady moisture. Mulch to conserve water.

Soil and pot

Hydrangea 'Pinky Winky' grows best in moist, fertile, well-drained loam. Adaptable, fertile, well-drained soil over a wide pH range. Flower colour is not affected by soil pH. Enrich poor or heavy soils with compost. 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

Hydrangea 'Pinky Winky' sits happiest at around Ambient outdoor humidity and -34 to 30°C (-30 to 86°F). A hardy garden shrub with no special humidity needs; thrives in normal seasonal outdoor air in temperate climates. If you keep the room above 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 hydrangea 'pinky winky' sparingly. One application of balanced slow-release shrub fertiliser in early spring. Limit nitrogen, which encourages floppy growth and fewer flowers. 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 hydrangea 'pinky winky' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Weak two-tone colour — The pink tones deepen in cooler weather and good sun. In heavy shade or very hot conditions blooms stay paler and less distinctly two-tone.
• Flopping stems — Excess nitrogen or heavy blooms after rain can bend stems. Feed lightly and prune in late winter to build thicker, more rigid wood.
• Poor flowering — Results from pruning at the wrong time. It blooms on new wood, so prune in late winter/early spring only.
• Powdery mildew — White coating in humid, still air. Improve airflow, avoid overhead watering, and remove affected foliage.

Propagation

Softwood cuttings in early summer root readily. Patented cultivar ('DVPpinky') — propagation is restricted to personal, non-commercial use. 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

Hydrangea 'Pinky Winky' is toxic to pets. ASPCA lists Hydrangea as toxic to dogs, cats, and horses, with cyanogenic glycoside as the toxic principle. Ingestion typically causes vomiting, depression, and diarrhoea; serious cyanide poisoning is rare and usually limited to GI upset. Keep clippings and fallen blooms 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.
