Hanging baskets with trailing petunia, and lobelia were planted in late May (after frosts) and were thriving initially. In last few weeks leaves have gone pale green and flowers have a faded 'washed out' look, but are not falling off. Baskets have been kept watered and fed with tomato feed (maybe too much?) from the start. I have been growing baskets successfully for several years and never saw this problem before.
