I’m probably just being paranoid but I would like advice please. I am new to rose gardening. About a month ago I planted two knockout rose bushes in my yard. One is doing fantastic.... the other not so much. I noticed a drainage issue where the sad one is planted so I did my best to amend the soil and raise the bush up to prevent root rot. This morning I came out and noticed some weird new growth, I am attaching photos. Hopefully I am just being paranoid, i just have nothing like this growing on my healthy knockout. Is this normal or possibly early rosette? Maybe it just needs to recover from the other issue?
