Hi there, I bought 3 Chrysanthemum plants a few weeks ago. They were all pretty root bound in their pots so I transplanted them immediately, (2 into separate pots and 1 in a hanging basket). They've all been doing reasonably well, until about a week ago, the 2 in pots have started wilting a bit. Their flowers are slowly wilting too and losing their colour. They get over half a day of sunlight, and I've only been watering them when the soil is bone dry - every few days. I've found no rust or possible symptoms of fungi, the leaves and stems seem to be healthy (besides the wilting), and theres no infestation that I can see..... I'm not quite sure what I'm doing wrong, I would greatly appreciate some help and advice
