My African Violet plant went brown over the weekend.?

Question

It's a concord blue - streptocarpella for you plant people. And it looked like it was doing great. I watered it before I left Friday and when i came back into work it was all brown and dead looking. I should note that my office is usually extremely hot - around 90 degrees. Could it have gotten too hot over the weekend? Or maybe it was the opposite -the heat was off and it got too cold??
I trimmed most of the brown stuff off and am left with a sad looking plant. Is there any way I can revive it? Any ideas on what happened so I can prevent it?

Answer 1

Water it from the bottom, not the top. Water on the leaves kills them.

Answer 2

Its an African plant, its SUPPOSED to go brown!
