What is this and how do I treat it?
I've got some store bought spray I can use on the aphids but I might need to buy some more to take care of the hordes!
The ants is another clue of aphids. The ants milk the aphids kind of like dairy cows are milked for their milk. Where there are lots of aphids, there will usually be lots of ants sooner or later.
Thanks for this, it was what I thought but I got confused by the colour of the bugs, i.e. white instead of green. Also, the plants are covered in ants!
It looks like you have an Aphid Convention going on there on your rosebush!! With that many of them, I recommend getting a good insecticide and spraying your roses down well with the insecticide at least twice. Many insecticides will take out aphids so read the label on those available at your local garden center or nursery. If there were just a few, a stiff spraying with water for 3 to 5 days would send them packing too.

Can I safely use dry horse manure around rose bushes? If I do use this organic form of fertilizer on established roses now, how much should I use? I have an ample supply available.

Iceberg blooms droop and then drop after a couple of days. How do I get longer lasting blooms?
If you are having some high heat days and very warm nights, there is not much you can do. Keep them well watered and fed and they will do the best they can. Doing things to keep their planting area cooler will allow the blooms to last longer.
I heard it is in the soil. If so, how do I treat that?

My rose plant leaves are shrinking, another two roses are not growing new leaves and another one has new leaves that are falling in alternate stages.
If you are in a colder climate area, the colder nights could cause this. If not, the rosebushes may need more water to help get them going well. There could also be a fungus at work on them, spraying the rosebushes with a goof fungicide could be in order.

My bush was old when I moved here in 1974. Do not know name or type. Red in color and not real full with many hips after blooming, one big bloom in spring early summer and then a constant small bloom until late fall. It was under a white pine until about 2010 and then tree pruned back and it came to life and grew to twice its size and many more flowers. Would like to get starts to give kids who grew up here (3) so they could plant at their new homes. I have spent 10 min trying to send picture but cannot - it should be under my e bob2skoge@gmail.com Picasso 3 web album ,but they make it too hard for people like me.
Here is also an article on growing roses from seed. However the seeds will not give you exactly the same rose due to the pollen mixing by the bees. Link: https://www.gardeningknowhow.com/ornamental/flowers/roses/growing-roses-from-seed.htm
Wonderful story on your rosebush Bob. Here is a link to an article for you on taking cuttings and starting new rosebushes from them. It can be a tough process, so take plenty of cuttings and be patient with them.
