Knock Out Roses by hozn
TheGardenLady received this question from Mary Jane about a problem she was having with her knock out roses.
I planted eight knock out roses in the sun last year and they bloomed. After blooming the first year I put mulch on the base of the rose bush and the ground was not frozen. This spring I cut them back slightly the first bloom was great. We went on vacation and had a bad rain storm and the roses stopped. What am I doing wrong.
Here is an answer to your question from the experts:
Knock OutÂ® roses will go through a blooming cycle. In the northeast they typically come into their first flush of flowering around Memorial Day weekend. They may not bloom as much for a few weeks, but will then flush another round of flowers in two to three weeks. The can be in bloom all the way up until Thanksgiving depending on the weather.
