Hey,
I bought a band of this rose this spring, and it did wonderful until we had a bad heat wave in july. my question is she's in afternoon sun and would she do better with afternoon shade. she's still alive but completely defoliated, and she keeps trying to come back, but everytime she gets a couple of leaves we will have a hot day and she's stressing. I've been giving her plenty of water.should I move her now or next spring? since she can go down to zone 3 I figured she might like more afternoon shade.All comments,recommendations are welcome. I know she can live here I just need to find the best spot for her, because before the heat wave she was throwing up new shoots and growing like a weed, but I need a little guidence. Thanks |

| My experience with rugosa roses in general is they do NOT like heat. They are happiest with colder weather, good drainage and regular water. Can you provide it shade with something until the rains are expected? If you can, it might be safer to wait until you can expect rain to transplant it in case the roots suffer too much trauma in being moved. If you are confident you can dig it with all the roots intact, and can put it somewhere you can protect it from the hotter sun and time of day, it might work moving it now. Personally, I'm not moving anything until this heat subsides and I can be sure the weather is going to help me keep things watered. A good rain can cover a multitude of sins. Kim |

| Thanks Kim, we are supposed to get rain tomorrow, but then back in 90's again, so I don't know if it would be better to wait or not :( but we are supposed to start cooling down soon :) |

| Kim, I have another question, Sorry, how about rosa glauca, it's put on new leaves since the heat wave but no growth it gets afternoon sun as well but not as much, would it need to be moved as well or should I wait and see what happens? |
RE: Question about Rosa Rugosa Rubra

| You're welcome! Per Wikipedia, Glauca "is a species of rose native to the mountains of central and southern Europe, from Spanish Pyrenees east to Bulgaria, and north to Germany and Poland." But, some of our hotter areas could easily be too much for it due to the darker tones its foliage contains. If nothing else, I would think the foliage color would be better if grown where it receives morning sun, with protection from the hottest afternoon sun. R. Fedtschenkoana, though not darkly tinted, also prefers afternoon shade. Growing it in the hotter sun and temps, instead of being turquoise-silver-green, it's rather yellow-green. If you are likely to get back up into the heat extremes after your rain, I'd want to wait until there is moisture and cooler weather. Both of your roses may begin to lose their leaves due to their deciduous natures, so don't flip out if they start losing their foliage and looking sickly. Nearly 30 years ago, I imported Euphrates, one of the early Harkness Hulthemia hybrids. Not remembering it was deciduous, when it began turning yellow and dropping its foliage, I just KNEW I had killed the blame thing! It was the first truly deciduous rose I'd grown. Kim |

| Thanks Kim I'll wait to move them and go ahead and just look for their new home :) The funny thing is they probly would have had plenty of shade where they are now but I got my husband to cut down a couple of small trees and some of the lower limbs off the bigger trees so my roses would get more sun! We have 2 and a half acreas but we are surrounded by trees on three sides where we decided top put our house at, at the back of the property, and so I'll just have to move some a little to the front where their is no afternoon sun :) |

If I may add some information about yor "very" hot rose. A lot of people over here in Australia(Oz) place umbrelahas over their show roses to protect them from the sun, as Kim has mentioned it is the heat and afternoon sun effecting it. IMO I would try to place a shade barrier to stop the afternoon sun, not to close as this can also make it hotter.
Regards David. |

| Thanks David. That's a good tip about leaving some air space between the shade and plant to prevent trapped heat build-up. Kim |

| Another bit about rugosas in hot climates: Back in the 1980s, I was under the impression that they would not grow in hot climates, and certainly, they were not thriving for me. Then I visited Robert Basye in Texas, and he had huge, tree-like rugosas in his climate that regularly tops 100F. He said the secret was to graft them to 'Fortuniana' rootstock. I was already doing that with other roses, but had not tried putting R. rugosa or its hybrids on Fort. So I went home and tried it. Since then, they are easy roses to grow. Granted, Lakeland Florida is not "hot" by some standards -- we only reach 100F every 4-5 years. But we do have consistent heat -- often not a day with a high of less than 90 from June 1 through Sept. 30, and lots of days in the mid- to upper 90s, with high humidity (I suspect the humidity helps in this case). Yes, they do get stressed somewhat in mid-summer, but no worse than other classes of roses. And they flower pretty much continuously through the period. Ours are in all-day full sun. I've not tried afternoon shade. Now that we have chili thrips, they have become more challenging, since rugosas are so sensitive to sprays of any kind. But we've used soil drenches of imidacloprid, and at least for now, that works. We dread the day when the thrips become resistant, and while I like to rotate materials for that reason, with a rugosa, there's not much else one can use. |

| Thanks David, Kim, and Malcolm for all advice and experiences even though I just joined the forum, before I joined I always looked at what everybody said on here comparing what everyone said on different matters made what the decision was much easier, so I respect what ya'll have to say on matters very much because ya'll have a lot of experience in them. Thanks again ya'll and hopefully they will start looking better soon. |
