Q.Can I plant knockout roses in late September?
I have a flower bed about 8 feet long. It does not have anything yet. I want to grow knockout roses there. I am not sure if I should wait for spring or can I grow knockout roses at the end of September? I live in Houston, TX.
Kindly reply back. Thanks
Kay

Yes you can but be sure to water them in with some super thrive and root stimulator in the water. Spring is truly always best but it can be done this late in your area. Be very sure to keep a close eye on the soils moisture over the winter months. Here is an article for you to check out on this too:
