Geranium problem
 

I bought 2 beautiful pink geraniums hanging baskets. One is doing fine but
the other seems to have a problem. The leaves are turning yellow and
curling up. It appears the basket contains 3-4 individual plants and they
are bending over. I live in Western Pennsylvania, the past few nights have
been chilly (near 30) but I have covered them at night with a light cotton
sheet. The problems seems to have started before the chilly nights however.

Any suggestions?
Thanks,
Stell
