Hi-- I have two large flowerpots that each have an osteospermum and a tickseed planted in them. They are at the end of my driveway and get full sun. They were planted at the same time with soil from the same bag. Both pots have been watered the same. They looked great last Monday when I left to go out of town for a week. I came home on Sunday and found that one osteospermum is wilting and one is flourishing. Both tickseed plants look great. I watered both before I left, and I believe we got rain one day mid-week while I was gone. I am not an expert gardener and am trying to figure out if the wilting one is overwatered, underwatered, or if it has some kind of rot or fungus. I do not see any spots or mold on it, and it seems to be firmly planted within the soil. I watered it when I got home and it seemed to perk up slightly, but the next morning it was back to looking quite wilted. Any advice is appreciated.

This is most likely a watering issue, one of your containers may be draining water more quickly. Soil can dry out at different rates.
Container plants may need additional watering when days are hot, even twice a day in some cases.
