Hoya care

Hoya carnosa

Thirsty’s starting schedule for Hoya: about every 10 days. Check the soil and adjust it to your home.

Watering

Let the soil dry out between waterings and never leave it waterlogged; overwatering is the most common problem and often leads to root rot. Water less from October to February. [1][2][3]

Light

Bright, indirect light, such as near an east, west or south window; hot summer sun can scorch the leaves. [1][2][3]

Humidity

Likes high humidity; a humidifier or a tray of wet pebbles helps. [1][2]

Soil and potting

A loose, fast-draining mix, such as potting mix with orchid bark and perlite, in a pot with good drainage. [1][2][3]

Pets

Non-toxic to cats and dogs. [4]
