What size is the pot?

You may have too much nitrogen which would burn the leaves or make them look off-color.

I'd say, 'First Prize' is not a rose that will succeed long-term as a pot plant. It probably needs to be in the ground. Then, it will need time to establish itself, and grow good roots, before it is pushed to bloom a lot.

The plant is in 15gallon container and does have dolomite lime and controlled release osmocotes fertilizer in it. I do agree roses do much better in ground than in pots but I am re-doing my yard and will have to maintain this plant in pot until I find a location in ground for it. I am not concerned for the bloom but the leaves coloration and why this specific rose it not taking the nutrients correctly. I have other roses in containers too and I do not see the same problem on those plants. Thanks

I would go on line and google images of rosé deficiency or problems. You could find something g that matches what you are seeing with a diagnosis. description and suggested treatment.

Ortho and others have "growing roses" books that can be helpful too.

I think Jerijen is right. Of my first 6 roses planted a little over a year ago, First Prize is the only one not gorgeous, healthy, and reaching for the sky. It is coming along VERY slowly. It is planted in the ground with everything wonderful that I can give it. The others have responded very well....First Prize. I wouldn't buy again. It had BS the worst and just looks puny. Since the others are so happy and healthy, I can only surmise that this rose doesn't like me OR where we live.

You should at least, get it into the ground.
