I think this is could possibly be a magnesium deficiency. My source is "Compendium of Rose Diseases (1983) APS Press. I also wonder if this is not last years leaves getting ready to drop since the Florida growing season probably is not cold enough to make a rose drop all of its foliage in the winter. The new growth looks healthy and vigorous with no signs of distress. Even here in Oregon I see those kind of old leaves in spring on the hardiest roses which did not drop foliage I doubt it to be RMV. All own root roses of this variety sold through 2017 originated from virus indexed mother block from Germany and all own root propagation was from the original stock. No licensed producer used cuttings from budded roses; so while it is impossible to say it does not have RMV, it is unlikely. If you bought the rose locally in Florida it was grown in fields in in Arizona where there is RMV, but it is usually passed on through the root stocks and from infected grafting materials. It typically does not spread to the own root roses unless cuttings were taken from infected plants - from budded plants. I would watch the plants and see if any more mature foliage develops these symptoms, if so, I would think about adding some micro elements to the fertilizer. My guess is these leaves will drop and your rose will look great. Looks like you have a lot of buds coming.

I’m also thinking that they may need pruned again. The green canes look a bit on the yellow side. This is some thing that you will see in a winter killed cane. In a good cane the inside well be white to apple green. Even a damaged cane can produce growth it just won’t be healthy. It’s a bit scary to prune to much right now as the rose may have used a lot of energy leafing out on bad canes. If it were mine I’d prune again to clean white center even if it goes to the ground because it looks as if those cane are not going to make it. Keep in mind that it is only what I would do. Others may disagree. I also agree that maple trees are hard to plant around they have a very shallow root system. It is possible that the tree has starved the poor rose to death.

Lovemycorgi, so funny. I bought mine as a second choice as well. I think I went to get Empress Wu and the only one left was hail damaged. I have resisted dividing it because it just looks so perfect and it was always off to the side. I’m not sure if I should do it early spring or what.

where are you in z5... its about half the US and very divergent ....does your ground freeze?? in my z5 MI.. i would have to cut it to about 6 to 8 inches.. bury it in mulch and cover with a rose cone .... watch for very warm zone suggestions.. if you dont cut it back.. winter winds will most likely kill it back to snow cover.. or lower... hence the rose cones and mulch ... your plant looks like its planted very deep... cant really see properly in the pix... if so.. it might not thrive properly... why it MIGHt be struggling... the usual suspect for winter problems in colder zones .... is prevailing winter winds.. and sun.. the canes thawing during warmish winter sunny days.. and refreezing ... even freeze drying during the night... i used to say.. a plant has a sense of humor about it the first time it happens.. is rather upset the second time it happens showing significant damage.. and will just about outright die the third time... and it seems you do not have some little winter wind free micro climate.. in that first pic.. looks sorta prairie like... i bet the winds whip thru there when the corns gone.. if in fact that is corn over there... fertilizer is never really a remedy for anything.... applied properly.. it rarely hurts.. as long as you stop by 9/1 in z5.. but it seldom ever fixes a problem ... ken
