How to Grow Polka Dot Plant
Hypoestes phyllostachya
Polka dot plant is a compact, colourful houseplant grown for its spotted or splashed foliage in shades of pink, red, or white on green. It needs bright indirect light to keep colours vivid — too little light fades the pattern. Keep the soil consistently moist and humidity high; it wilts quickly when dry but recovers fast once watered. Pinch out shoot tips regularly to stop it going leggy. It is non-toxic to cats and dogs, making it a safe choice for pet households.

Pet Safety
Care Requirements
Light
Bright indirect light
Needs bright indirect light to keep leaf colours vivid. Direct sun scorches leaves; deep shade causes the pattern to fade to plain green. A north-facing windowsill with good sky light or a spot set back from a bright window works well.
Watering
Keep soil consistently moist
Water when the top 1–2 cm feels just dry. Does not tolerate drought — leaves droop quickly when dry but recover promptly once watered. Reduce slightly in winter but never let the pot dry out completely.
Fertilizing
Fortnightly in spring and summer
Feed every two weeks with a balanced liquid fertiliser at half strength from spring through summer. Stop feeding from autumn onwards when growth naturally slows.
Pruning
Pinch out tips regularly
Pinch out growing tips every 2–3 weeks to maintain a compact, bushy shape. Remove any flowering stems as they appear — flowering signals the end of the plant's display and energy should go into foliage.
Humidity
Prefers high humidity (50%+)
Brown leaf edges indicate dry air. Mist the foliage regularly, stand the pot on a pebble tray with water, or use a humidifier nearby. Keep away from radiators and air conditioning vents.
