Alerte Jardinage

Bon, vous pouvez m'expliquer comment faire fleurir un cactus quand votre envie de bouffer mes cactus passera 

Hello, I have been growing the same San Pedro cactus for 10 years now, last winter they became so tall, and I got tied up in school, and left them to flop over and die...almost. I decided I didn't want to grow cactus anymore and got rid of the largest one that had flopped over due to lack of water, then my heart string tinged and I realized I just couldn't let them go completely after growing them from little pups.
So here we are, one large cactus that has given birth to many many cuttings, and 3 new pups for the summer.
in the 10 years I've had these cactus I've never gotten a flower!
