Use room-temperature water and let any excess drain. Never leave the pot sitting in standing water.
Adjust the timing for the light at the plant, the pot’s size and material, and the humidity indoors. Terracotta dries faster than glazed ceramic.

Light and placement
Bright / direct light
Peruvian apple 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 peruvian apple cactus every 30 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.
