    It is better if roses don't have other vegetation growing under their drip line like I see in the second picture. It competes for nutrients and water and hinders good air circulation. Your greater problem may be rose rosette disease. The new growth in the first picture is blurry when I enlarge it so I don't know for sure but you should investigate this fatal disease of roses. I would also encourage you to look at videos of how to prune roses. Your bushes are crowded and will benefit if more sunlight gets into the middle. Air also circulates better and this helps prevent leaf diseases. Meanwhile always clean your tools after use on each rose. If you need more information, please send a close up of a leaf cluster. https://chadwickarboretum.osu.edu/sites/chadwick/files/imce/pdf/Buckeye_08August2014_Hand.pdf

    Rose trees are grafted trees. The new trunk coming up is from the roots of the grafted standard that the top desired rose was grafted onto. So that would not produce another rose tree. It is best to prune out the new trunk as it only steals nourishment from your current rose tree. Sorry to say this but eliminating the new growth is the best thing you can do for the rose tree you love. Her is a link to an article I wrote about rose trees for you: https://www.gardeningknowhow.com/ornamental/flowers/roses/learn-more-about-tree-roses.htm

    This article has information on rooting rose cuttings.
    This would be the technique we think has the most success.
    Not every cutting will take, so try not to get frustrated.

    I'm no expert on plants but i have 3 rose bushes in front of my house. They were kinda the same way so i trimmed mine down to about 2 foot tall about 2 months ago and they are coming in plump and full now and are starting to bloom. unfortnately I am at work so I have no photos to share. I don't think it would be wise to cut them back now since they are in bloom but maybe after the bloom is over trim that back

    Your roses look like others I've seen that aren't getting enough sunlight. They must have at least 6 hours of direct light daily. Another possibility is that they are getting too much nitrogen. Are you using a fertilizer meant for flowers?

    Contact J&P. They may have heard of problems with other shipments and will give you a refund. In my opinion, you should be seeing new growth by now.

    This looks like damage from sawfly larvae, also called rose slugs. Search both sides of the leaves to find the green worm-like culprit. Insecticide for rose sawfly is available. Here is more information. https://www.gardeningknowhow.com/ornamental/flowers/roses/rose-slugs.htm

    Some of what is shown is from either water or a spray of some kind sitting on the leaf structure too long. The water sitting on the leaves too long acts like a magnifying glass and burns the leaf tissues. Thus the brown spots with yellow around them at the highest moisture retaining spots, then going to more yellow, then brown. Once the tissue damage has been done there is little that can be done to stop it. I prune off the entire leaf set back to the cane. Take a look at your watering system, or if you hand water like I do, the time of day which watering is done. I suggest watering in either the early morning so any water on the foliage has time to dissipate before the suns rays get intense or early evening once temps have started to cool.
