Spider Plant Disease?

ParisPolyphyllaOctober 10, 2012

I have two medium sized spider plants for about 1.5 years now. The past month I have noticed that entire leaves have been turning yellow and then really pale with reddish-yellow spots before wilting away. Whatever this disease/pest is it has been working from the outside leaves (the older ones) in.

I water them about once every ten days (when you stick a finger in and the soil feels dry). I don't see signs of too much chlorine in the water and the tips aren't brown. The plants are placed by a north-east facing window and they've just been repotted this summer.

Both spider plants have produced plantlets and I also see that in the plantlets (both still attached to the plant and/or repotted).

Help anyone!? These plants are losing a lot of leaves this way...

Thanks!

Have you checked for spider mites? Under the leaves, they may be hiding and they create webbing near the leaf axil.

Paris, sensitivity to fluoride is the first thing that comes to mind with leaf spotting of Chlorophytum. Unlike chlorine, which will evaporate away if you leave it sitting overnight before using it, fluoride can get even stronger. Some people see improvements when they switch to distilled water. Perlite is another source of fluoride.

I am concerned about what might be going on with the root system since your repotting. Yellowing and loss of leaves usually means that something is "off " with the root/soil system. Is the new potting mix a nice, porous medium? Do the containers drain rapidly?

Yellowing can be caused by too much or too little moisture. Be sure that the plant dries out before watering again, then do so thoroughly. If the crown has begun to experience root rot, all bets are off.
