These roses can take the Texas heat, and neglect, too!
Texas is notorious for climate extremes, from high heat and humidity to frequent droughts. So what better place to test roses for their ability to withstand utter neglect?
That’s what the Earth-Kind Roses program from Texas A&M’s AgriLife Extension Service set out to do. Researchers tested roses for survival with minimal maintenance—limited watering, no added fertilizer, and no treatment for diseases or insects.
Some of the top performers (recommended for Texas and similar climates) included ‘The Fairy’, ‘Perle d’Or’, Knock Out roses and ‘New Dawn’.
Earth-Kind Roses trials are now being conducted at a number of other sites around the country.

I have several Knockout roses. They are doing very well in our extreme heat and water restrictions North of Austin Texas However so far I have only found the red rose. I would like to know if there are more currently available or must I wait until the current trials are completed.

I love roses, and have been trying to find one that will survive the extreme heat we have been experiencing in the midwest.

In what part of South Carolina did you purchase the knock out roses? Do they take the extreme heat and humidity that we have here and to what degree of cold do they take? I live in Cayce,SC which is about 5 miles from Columbia if that far. I love roses but finding one that will thrive in extreme humidity is hard.

the knock outs are doing GREAT here in south west louisiana, and my summers have been extremely hot recently. we also have high humidity normally. i've got 2 sunny knockouts (the yellow ones) 2 pink double knockouts, and 3 red knockouts in addition to my many other roses. the knockouts bloom profusely and almost endlessly! i completely love them. whenever i can find one, i'm going to purchase one of the newer multicolored knockouts, too!

Responding regarding care of "knock out " roses in AZ. What zone in AZ do you live in? I have pink and red in the high mts (7200 ft) which freezes in winter and is dry most of the summer except in "monsoon" months of July, Aug, usually.Last winter was extremly cold and my red one is barely alive. The pinks did very well and both bloomed all summer. I never cover them in the winter, just spread 2-3in. of mulch, keeping about 2in from the stem, they are dormant, then come to life in late spring. I do fertilize them during blooming season and water during dry spells. I have only 1 living rose at my desert home (zone 8-9) and 2200 ft. elevation. This area requires some shading in the afternoon from hot summer sun ( which I learned after losing 3 others) and they have their last blooms about this time of the year and all spring and summer. Most hybrid teas will be fragrant and do very well in this area. No winter protection is needed. Plants in AZ do need different care than most other areas due to alkaline soil, dry, and temp extremes. Good luck. Sandra

I live in central North Dakota, the Rainbow Knockout I purchased from Lowes is WONDERFUL,it blooms vigoriously all summer,I don't cover it in winter. The Fairy is equally wonderful.Our weather is very cold in winter and has serious heat in summer.

i was wondering if anyone had trouble with deer eating their knockout roses. I have some planted at my house in ne ga, they do very well up there, but the deer seem to eat them down to just branches.

I have been growing roses for over 35 years in many parts of the country. The one thing that is constant is the need for adaptation to the climate. Not an easy thing for such a finicky flower. In Texas I had to plant in a partly shaded area to grow hybrids and double blooms, in upstate new york it was hay mulch in winter and cut backs in late fall. I now have lived in Florida for many years and am only 4 blocks from the ocean. The growing of roses here has been the trickiest. You have to allow for salt, heat, hurricane and drought. Good well drained soil is great but you have to built it yourself because of the sand. Manure and good potting soil mixed with sand 1 part each is great. Also do not cut too far back until very late fall. Trim dead heads and spindly limbs in th meantime. Happy Growing

I live in Kansas and 2 yrs ago, planted 19 Knock Out roses, both single and double blooms....they have done so well that after two years, they went from less than 2 ft high to over 5 ft high! I had to seriously prune them back this year; they bloomed until November and were absolutely beautiful. Very heat tolerant, disease free, and I live in an urban area w/lots of deer and they did not bother them. I do wish they smelled more like roses....some of them have a faint smell, but most do not. Small trade off though for an otherwise easy-care rose as compared to other types.

Yes, I am having trouble with deer eating my roses! I've have marigolds planted around them now and hope that the smell may deter them. Time will tell. I've noticed that the deer don't bother my herbs so I'll be interplanting more herbs around the roses next spring.
