SOS my Senetti is struggling
I bought this gorgeous purple Senetti from Homebase about a month ago. It didn't come with many instructions. Firstly I potted it and put it in my front garden where it quickly became battered by the wind. So I moved it to a sheltered area and all seemed to be well. But now a month on the flowers seem to be struggling. I keep it well watered and have been regularly feeding with a general npk. No signs of slug attack although I did notice a few ants on the flowers and some of the petals have dark spots on them.
I've been dead heading the unhealthy looking flowers but if I carry on its going to look like Morticia Addams' plants on the Addams family
Will post some pics.
Appreciate any advice you have guys.
