Thriving impatiens completely wilted!
I live in NYC and one of my potted new guinea impatiens has completely wilted. As in all the leaves are drooping downwards and look completely shriveled, but strangely only a few leaves are dry to the touch while the rest are not. I potted this and another impatiens in early spring and this one had been doing great all summer, into the fall, until just this morning! I had watered it with flowering plant food on Sunday morning, didn't water yesterday morning and it rained a little this morning so I decided to give it a little more water later in the day today, which is when I noticed how awful the plant looked. I watered it every day in warm weather and since the weather's cooled, almost every day though I very occasionally have skipped one day, but no more. And when it rains, I don't water. I also have been giving it liquid plant food for flowering every weekend, including last Sunday. The weather's been 50s - 60s, quite mild. In any case, I have had these impatiens for 5 months doing what I've been doing, have done nothing different recently and out of the blue, this impatiens is doing terribly. The other one, which is right next to it, looks just fine. Any idea what is wrong with it? And what I should do with it?
