I've had these lovely white pelargoniums for 4 years in a pot with bacopa and white allysum. I've never fed them any other year than this and each year I just scrape away the top couple of inches of compost and replace this couple on inches with new multi-p. They always come up nicely.
A week ago they were budding nicely on nice fresh new shoots with buds. For some stupid reason, as I was going around feeding potted plants with liquid tomato feed and without thinking poured some (highly diluted) also into the white pelargonium pot.
Now, the flowers are mis-shapen and are opening with green veins on them all, as you see in the photo. The whole pot photo is July 2013 and the green veined flowers photo was taken today.
Do you think this has happened due to the erroneous tomato feed - or is this some other condition which I could possibly rectify? Or not?
