Water your golden barrel cactus when the soil has dried out completely, typically every 17 to 25 days while it grows. In winter it rests: keep it almost dry and water only sparingly until new growth starts in spring, because wet roots can rot during the rest. Let any excess drain and never leave the pot sitting in water.

Light and placement
Bright / direct light
Golden barrel cactus needs several hours of direct sun. Turn the pot every week so it grows evenly. Place it directly in front of a south- or southwest-facing window.
Feeding
Feed your golden barrel cactus every 90 days while it’s actively growing. Use a cactus and succulent fertilizer, which is lower in nitrogen, at half the strength on the label, and only on soil that’s already damp.
When growth pauses, skip the fertilizer and let it rest.
Temperature & humidity

During leafy growth, aim for 10–30 °C (50–86 °F). For routine indoor care, keep it above about 8 °C (46 °F) and avoid cold drafts. This is a care guideline, not an exact damage threshold. Cooler overwintering depends on the species and its rest conditions.
It does best at 20–50% humidity. It doesn’t need misting.
