Will my cactus bloom if I keep it in a dark corner?

No, this plant requires intense, direct sunlight to store enough energy for flowering. A dark corner will only lead to weak, etiolated growth.

How big does the cactus need to be to flower?

While it varies, these plants typically need to reach a height of at least 3 to 4 feet before they are mature enough to bloom.

Check these first

Measure the amount of direct sun the plant receives each day.
Check the overall height and maturity of your cactus.

Likely causes

Insufficient light
Most likely
How to tell: The stems may look thin or stretched, and the plant remains strictly vegetative. It needs at least 6 to 8 hours of direct, unfiltered sunlight daily to bloom.
What to do: Move your cactus to a south facing window or an outdoor patio that receives full sun. If you cannot provide enough natural light, consider using a high output LED grow light for 12 hours a day.
Lack of maturity
Possible
How to tell: The plant is healthy and growing well but is simply too young to reach reproductive age. Peruvian apple cacti often need to be several feet tall before they produce flowers.
What to do: Continue providing consistent care and patience. Keep the plant in a stable, sunny spot and wait for it to reach a larger size.
