I have two daisies planted 4 feet apart. I planted them last year. One is doing perfect, but the other has stems that seem to be wilting. I removed the dead stems and noticed the base(close to the root) was black and dried out. I think its insects or disease. What can i do to save it?

The black areas at the base of the plant sounds more like a disease than an insect problem. The stems are wilting because the vascular system is closed up and the stems are not getting the water they need. I'm not sure you can save the plant. Root rot, from poorly draining soils and from overwatering can completely kill a plant and by the time you notice the symptoms, it's too late. You can try digging up the plant and pruning off the blackened stems and any affected roots and then replanting what's left of your plant, or you can simply toss the plant and replace it with a healthy new plant. I'd vote for replacing the daisy. It seems that once a plant endures an attack, whether by insects or disease, it's never quite as healthy as it once was and never performs as well as it could. Best wishes with your garden.
