knockout rose types - Knowledgebase Question

Winter Haven, Fl
Question by profbob

I planted 8 knockout double reds last year (bought at different times).
Two are doing really well -- nice blooms and green leaves, three have died, three more have red leaves at the moment - no blooms yet.
Are there different species of double reds to explain these differences? If so, which are most productive?

There's only one double red Knockout Rose so the behavior of your plants is more likely due to soil conditions or exposure to weather (a microclimate, perhaps) than to a difference in cultivars. The red leaves are normal. All rose leaves emerge with a reddish tinge and then turn green as the leaves mature. Pruning your roses will encourage healthy new growth and lots of flowers. I'd prune them back now and this summer they should bloom profusely for you. Hope so!
