Oh wait!!! I actually did one overhead watering recently... maybe a week ago? Maybe more? To try out feeding them with silicon (Protekt). Maybe I did the damage!

Wait no... I didn't do any overhead watering for Pretty Lady Rose so that can't be the only thing going on here. It's probably a combo of me overheard watering that once, the heat and flower thrips. What do you think?

And if that's the case... when should I overhead water if I want to continue feeding with silicon (Protekt) every few weeks or so? At night?

Thank you!

Been going through that here...Too much rain and I found thrips inside blooms...Shake the blooms over a white piece of paper the thrips will fall out and scamper if you have any... Those things are small...

I wouldn't think that only watering overhead every few weeks would cause that....Wouldn't think so anyhow... Unless the water laying on the blooms caused frying from your intense sun...???

"Unless the water laying on the blooms caused frying from your intense sun...???"

That's what I was thinking Jim. They're not really fried... they look kind of steamed. But the ones in the front yard, like Pretty Lady Rose, don't have that same look. Just little brown edges. That looks like regular flower thrips.

On the others, I think it has gotta be a combo of regular flower thrips, the overhead watering and sun... I think. That's probably why it looks different than what I'm used to seeing.

Oh well. Nothing to do about that I guess, except figure out a different way or different time to do the overhead watering with the silicon (Protekt).

Some of the sprays cannot be used once temperatures hit around 90 degrees, Cori-Ann. I do not have a lot of experience with spraying, as the only thing I have sprayed, with no real regularity is an insecticidal soap, and I sometimes use neem during the Winter. Use during certain temperatures for at least one of the products was cautioned and I think that holds true for other products too....just thinking about info. I have encountered regarding sprays over the year. The result will be fried petals/blooms

Also, Love Song looks like thrip damage... which culprit.. I haven't a clue. I get thrip damage when it becomes Summer hot (now), but I do not know which one. There is a post regarding identifying Western, vs. Chili... etc. I will see if I can find it or maybe someone with a lot of thrip experience/knowledge will chime in.

Desertgarden that makes a lot of sense. I didn't think about that, since Protekt is a "liquid fertilizer" instead of a typical spray, but I did do overhead watering for foliar application... which basically makes it into a spray. The spec sheet didn't say not to apply when it is above 90, but even just plain water when it is hot makes the flowers steam up. I should have thought of that!

Maybe from now on when it is hot if I want to keep feeding with Protekt I will make sure to just get the soil.

If anyone is interested in silicon, It seems like some research shows promise that silicon like Protekt makes the cell walls thicker, making the plants stronger against heat, sucking insects, etc. Here's the main spec sheet: https://dyna-gro.com/wp-content/uploads/2016/07/Pro-TeKt-Sheet.pdf 

The research may show promise, but they had better tell users not to apply their product in temps over 85F, I would think. Even under 90F seems too high for me. Fertilizer can certainly burn. I occasionally use Miracle Grow hose end sprayer stuff, and I wait until the cool of the evening on a cooler day to apply it, and have never had a problem. Diane

Thanks Diane. Yes... application instructions instructing people not to apply over 85 would be helpful. I know better and I wish I would have thought of that. It's such a low number 0-0-3... that it didn't even dawn on me. But the silicon is about 8% I believe... and of course I didn't even think about that either. I will only apply in the evening from now on.

Oh well... only one application for the roses so far and not that much damage. Luckily I have all of you to be my brain when mine doesn't put things together. ;-)

Yup! Looks like I caused the look of Yves Piaget. There are definitely some regular flower thrips here too... but that steamed, rotted look of Yves Piaget and a few others looks like it was caused from me with the overhead watering to feed them silicon. Looking much better now!

I will definitely make sure to only do that in the evening from now on. Thanks everyone!

Great, Cori Ann! Now if thrips were only easy to get rid of. Diane
