Polka dot begonia care

Begonia maculata

Thirsty’s starting schedule for Polka dot begonia: about every 7 days. Check the soil and adjust it to your home.

Watering

Keep the soil evenly moist, letting it dry only slightly between waterings, and water less in winter. Never let it sit in waterlogged soil or a saucer of water. [1]

Light

A bright spot with some gentle direct sun, such as early morning sun from an east window; cane begonias like this one do well in partial shade. [2][1]

Humidity

Needs high humidity; raise the humidity around the plant rather than misting the leaves. [2][1]

Soil and potting

A moist, well-drained, humus-rich mix. [2]

Pets

Toxic to cats and dogs (ASPCA lists all begonias); it can cause vomiting and drooling, and the underground parts are the most toxic. [3]
