Is it just abnormal wilting / drying?

10 years ago

Hello, guys. Again asking for your experienced opinion. Today I was checking my roses after another 100 degree day. And noticed unusually red color on one of them. Do you think it's just abnormality that can happen in these temperatures? The whole plant itself is kind of strange. Started off really good. But the bloom was tiny, and I really mean tiny, like pinky nail... Smelled nicely. Then it started growing shootings from the bottom close to bud union. But still it was looking kind of weird to me compared to other roses I have. But it's the only one bare root that survived on me. I thought it could be the reason. But now everything is dying in this or that way in the opposite order. New growth first. Now this first band with weird colors... In real those tips look brighter. Is it like simple dying or is it kind of disease?

Thank you!

It looks to me as if your rose has "heat prostration". The red parts of the leaves is just dead, fried leaf. The tiny blooms are also because of the extreme heat. If it were mine, here is what I would do:

1) Move that shiny, heat reflexive gravel away from it. Cover lots more space around it with mulch - at least 20 inches in all directions.

2) WATER it more - If it is 100 degrees and dry, dry, you might need to water it more than once a day until the heat backs off a bit. Spray it and the mulch down with the hose.

3) DO NOT spray it with anything other than water, or feed it. Don't prune it right now either.

4) Rig some sort of SHADE for it - sticks to hold up shade cloth, or an umbrella, or a turned over deck chair, or something.

It will recover if you can keep it from dying from being cooked.

Thank you, Jacqueline... I knew that with this kind of summers I would have something like that... Just wanted to make sure it's not a disease or anything :) it was too bright red... I'm watering them once or twice daily... give them shower in the evenings... And this particular rose doesn't get too much of the sun since it's on the eastern side of the fence... Seems like heat started getting to my roses no matter what I'm doing to protect them... but I'm not giving up yet! :)

Looks like heat stress to me too. I would do exactly what Jackie said and, hopefully, it will recover.

Natasha, the heat is responsible for everything you've described.

Natasha - if you would, can you pls post a pic of it after you have removed the gravel, added/extended the mulch and added some more shade (even on the Eastern side of a fence, it is probably getting direct sun part of the time)? I would love to see it after you have rescued it - then see what happens.
