I have a gerber Daisy plant that was beautiful. The first blooms died, and the new blooms I now have have what seem to be underdeveloped petals. They fall off with the slightest touch and are a brown orange color (the gerber Daisy is a light orange). What could be the problem? I have done so much research and can't find any answers. The plant gets a fair amount of sun each day, but is not in full sun all day. I water when it wilts and fertilize regularly.
