How do you grow flowers on cactus plants?

Answer 1

Flowers grow, because of the appropriate fit between a plant's genetic inheritance and its environment. Specifically, a flowering plant blooms in response to necessary levels of heat, light, and moisture in its environment. That's why a cactus tends to flower after a rare desert rain event.

But not all cactus plants flower. Those that are capable of flowering may refuse to do so under certain conditions. For example, a cactus plant tends to flower more in the wild than in cultivation. In cultivation, it tends to flower more in the ground than in containers. So it also tends to flower more outside than indoors. The preceding may hold true regardless of whether the pollination is natural or gardener made.
