I have some knockout yellow roses. What do I need to fertilize them with and when? Do I cut them back like other roses?

You can prune your roses now. Then start fertilizing 2 weeks after they start growing in spring and repeat the fertilizer application according to type of fertilizer that you use. (Example): Miracle Grow liquid can be used every week, an Osmocote 4-6 month product can be used 1 maybe 2 times per year.
