Knockout Rose Sunny
Yellow / Rosa 'Radsunny'
( No Longer an Item that we stock)
Knockout Rose Origins:
- The Knockout is a carefully bred rose that was a result of crossing old heirloom
roses with more modern roses on a quest for a care free rose for all of us modern gardeners with little time and
no knowledge of what roses need and how to take care of them....and that is exactly what William Radler got when
he bred the Knockout line of roses. Thanks to his painstaking efforts you don't have to be an expert rosarian to
have a beautiful and healthy Knockout Rose bush in your front yard landscape. You don't even have to be much of
a gardener at all! Its the rose for the rest of us...so we can look like we know what we are doing without
actually having to know what we are doing. Its my kind of rose... Try it you wont believe how well they thrive
- A little side note that maybe not all roses in the Knockout family are
created equal. don't get me wrong, I'm a Knockout fan, but for some reason I have found that the sunny knockouts
aren't quite as hardy or rebloom as readily without a light trimming as the other Knockout roses
in the North Florida | Jacksonville | St. Augustine area landscapes. Not really sure why the variation in
hardiness and growth habit but there sure seems to be one with the sunny, the white and the rainbow. SO for the
rest of the country I'm sure these are stunning and carefree, but here in our North Florida gardens they
need a little more TLC than the rest.

down to 12" each spring and lightly as needed for rebloom through the growing season. .
- Add compost or cow manure yearly as a surface treatment pulling back the mulch and
spreading it around under the foliage of the plant on top of the existing soil. don't forget to remulch around
the plants to help them stay cool and help them to retain moisture in our hot sunny North Florida gardens.
- Plants respond well to applications of rose food and Milorganite or fish
emulsions each month in the spring summer and fall, sprinkling the fertilizer around the mulch circle
underneath the foliage of the plant.
