How to keep my knock out rose from dying
We have a knock out rose that came out this spring with several blooms on it. After the blooms died off, there was no indication that any new buds were forming. We cut the dead roses off and I fed the bush with some Ortho rose food. That was about 2 weeks ago and we have been watering in between rain at least 3-4 times a week. Right now there no new buds forming and the plant appears to be dying. What should I do?

Check to see if anything has been inadvertently poured on the ground near the rosebushes that could have burned the root system. Be sure the rosebushes soils are not too wet. Soaked soils do not allow proper oxygen movement into the soils and will choke off and kill a rosebush. Look the bushes over well and see if there are any insects causing problems, such as Thrips or Spider Mites. Check the foliage over well to see if any funguses are attacking the foliage. Here is a link to a website where you can visually identify some of the problems with roses: http://www.missouribotanicalgarden.org/Portals/0/Gardening/Gardening%20Help/Visual%20Guides/Rose%20Problems.pdf . It is best to positively ID what a problem may be so that the right course of action is taken.
