If it is thrips, you will be able to see damage in the white part of the rose. That is where it shows up most clearly. You will see brown streaks or tiny brown spots. In your case I would be tempted to leave it for a few days just to find out for sure which one is causing it. Once you know you can remove any damaged roses promptly. This may reduce (but not eliminate) the spread of the thrips. You'll probably take the proliferating ones off as well but it's not so important in that case. Rosefolly

MANY THINGS.. THAT ARE LITERALLY... crikey ... growing.. IN A FENCE ... are carp plants.. planted by bird droppings ... when they sat on tyhe fence and deposited them ... odds are ... your instinct is right.. and they all should go ... personally.. it would be a summer job for me ... so in the mean time.. i would let them leaf out.. get the IDs .... and have at them ... however ... if your motivated now ... it will be much easier.. to simply get rid of them ... and then.. once its all cleaned up ... then design and plant your own future nightmare.. lol .. like we all did ... that bath tub or whatever ... i know a lot of gardeners who would die for that in there yard .. so much design potential ... heck.. you could even make a fish pond out of it with a pump ...and im just talking 10 cent goldfish ... be done with it.. clean it all out.. and by fall .. you will be happy with it all ... ken

I’m starting to think there might be an insect issue however. One of my other cuttings has an inflo on it and has begun dropping buds like crazy all of a sudden :( They go from healthy looking to turning black and falling off within what seems like hours. I’ve lost 3 already this morning.

Jena, my Perle d’Or did the bud drop thing it’s first year, the whole year. A lot of my roses also had chlorosis, including Perle d’Or, even though they were getting regular Magnesium-sulfate and I was alternating between Miracle Grown and a seaweed fertilizer, all in the hopes of curing them of chlorosis. Mostly it was the Polyanthas and Multifloras that had this problem. Finally I sent in a sample for a soil test. I had plenty of all the minerals and nutrients except for Nitrogen (which I already knew since its obviously devoid of any organics and so I was fertilizing) and absolutely zero Manganese (Mn) detected. Once I put a teaspoon of Manganese Sulfate dissolved in a gallon of water on each rose last fall the chlorosis completely disappeared and Perle d’Or stopped dropping buds. I will now do this once or twice a year; not too often since Mn is a minor nutrient and too much can be toxic. The Miracle grow I was using did have trace Mn, but somehow it wasn’t enough. I wonder if my soil was just binding it up? This just demonstrates that bud drop could be due to lack of an essential nutrient. It might not necessarily be Manganese for you. But since you mention the Kellogg soil might not be that great, I would give it a nice dilute liquid fertilizer once a week and see if it cures it.
