How often to water Ball cactus

Autumn (Oct–Nov): Every 10 days; It picks up again in cooler weather: water when the soil dries, about every ten days, spacing out from November.
Winter (Dec–Feb): Every 30 days; Nearly dry, with a light moistening about once a month on a mild day; a dry winter improves the spring flowers.

Light and placement for Ball cactus

Generally a sunny spot, though it needs less glare than desert cacti; shade it about 30 to 50 percent in midsummer to prevent scorch, and keep it under the eaves in moving air or at the brightest window indoors.

Overwintering Ball cactus

Overwintering guide: 5°C (41°F) or above

As a guide, move it to a sunny window before nights drop below about 5°C; some kinds tolerate near 0°C when dry, so rest it dry in a bright, cool spot.
