I know I complain a lot about none of my plants putting out spikes. But I wonder if perhaps it's because they're too happy in my care. They get strong light, get fertilized weekly without fail, watered every time they're dry with no long gaps etc. All seem perfectly content getting bigger and bigger, and putting out roots like there's no tomorrow but it almost seems like they're saying "Why should we flower? What's the point? This is just fine." I'm thinking about cutting them off of all fertilizer or some kind of change for a couple of months just to see what happens.
