Rattlesnake plant care

Goeppertia insignis

Thirsty’s starting schedule for Rattlesnake plant: about every 5 days. Check the soil and adjust it to your home.

Watering

In spring and summer, water regularly to keep the soil evenly moist but not wet. Water less in winter, letting the surface dry a little but never the whole pot. [1][2]

Light

A bright spot out of direct sun; it tolerates only early-morning or diffused sun. [1][2]

Humidity

Needs high humidity; stand it on a tray of wet pebbles or keep it in a humid room. Low humidity can brown or curl the leaf edges. [1][2]

Soil and potting

A well-drained but moisture-retentive potting mix, such as a peaty mix or a peat-free compost. [1][2]

Pets

Non-toxic to cats and dogs; the ASPCA lists it as Calathea lancifolia. [3][1]
