What can I use to make my knockout roses more vibrant?

Seems like all of our neighbors roses bloom much longer than ours.

They look very healthy and we use Seven Dust for bugs. But the roses die out very quickly and I am left with a green bush with lost of dead roses.
Should I dead head the roses?

    take some fresh baked cookies to the neighbors and ask for their secret..lol---actually depends on location mostly...brighter sun, less wind, better soil....all make a difference...try sprinkling some epsom salts near the bush, but not touching it, then apply rose food

    You may also want to be sure to prune them back to about a third of their size in March (for NJ anyway...I'm not sure about TN) After pruning, cover the ground around the base of the plant with rich cow manure.

    Use Bayer 3-n-1 granulated fertilizer, and dead head spent blossoms.

    I deadhead my knockout roses on a daily basis. I also take my banana peels and dig them in around the base of each plant. Keep your eggshells and crush them and place them around the base of the roses also. Roses need 6 hours of sun per day to flourish. Mine bloom from spring through fall. Hope this helps!

    Roses need a lot of sun- about 6 hours. You should probably also feed them a couple of times over the summer. Roses like tea- same family! Use your leftover teabags to make a weak solution and give them a drink. Jerry Baker says put the teabags right on the soil, but I don't like to do that because of mold. I make tea for my azaleas and roses. You can do the same thing with coffee. Make a second pot with the used coffee grounds and pour the weak coffee on your plants. These are just easy ways of acidifying the soil.
