Q.Some Impatiens Looking Sickly
I have several impatiens in my garden bed. Some are doing very well, some not. I am wondering why. I frequently sprinkle dolomite on my plants (clayish soil)… I have cut the stems of the two sickly impatiens and applied liquid Powerfeed (fish fertilizer)..see photo Any suggestion? Otherwise will buy more plants to replace those two…

Did you check for insects? It's possible they missed your other plants. Too much nitrogen in the fertilizer can slow or stop flowering.

Does your cat do her toileting near those plants? Or possibly roll on them or dig?
