spider plants don't thrive
I'm frustrated by the fact that my spider plants are not thriving--and they're supposed to be some of the easiest houseplants to grow. Do you have any suggestions for me?
I purchased a medium sized spider plant about two years ago, which I pretty quickly browned up by watering it with municipal water (I researched and figured out the reason why the leaves were browning, and have since switched to bottled water for the spider plants). Unfortunately, the plant never recovered, and my kitty took to munching on it, further preventing its recovery.
We recently moved, and I replaced the dead spider plant with two, smaller ones, which I repotted and have only watered with bottled water. The cat cannot get to these plants, and is perfectly content with his own cat grass now (so no nibbling is going on). Nevertheless, the tips of both spider plants have turned brown and wilty.
I don't understand what is killing them. I also don't know what to do in order to help nurse them back to health. Should I prune the browned leaves so the plants don't waste resources trying to support them? Or should I leave the plants be as much as possible? Should I try giving them a boost with a bit of liquid fertilizer? Is this normal (die-off due to roots reestablishing because I repotted the plants)?
I've had luck with mother-in-law's tongue, jade trees, aloe, and devil's ivy, and the new dracaena plants I have seem to be doing fine. But this "impossible to kill" plant seems to be awfully delicate, and I don't understand what I need to do to rescue them.
Thanks for any advice.
