I have lots of spider plants which originated a number of years ago from a very large mother plant. What I do not understand is that only three develop stems with young plants on. All the rest have very long stems full of little white flowers but they just die off and do not produce babies. I just cut them off because they are tall and ugly. Why do they not produce baby plants.
Are they all potbound? Do they all have similar growing conditions? It could be anything from cold drafts, a build up of fertilizer salts, not enough fertilizer etc. I wish I could be more help but I usually end up with a ton of babies on my spider plants when they're root bound and fertilized a little at each watering. Also a summer outdoors for these guys if you can really perks them up. Good luck, Ryan
Producing adventitious plantlets on the flower stems requires much energy. Maybe your plant needs fertilizer and more light?
