Hey Cass, the fertilizers you point to here are WAY too nitrogen heavy
for roses.

The best rose fertilizers have an NPK ration of 1:2:1 Those above
fertilizers have ratios of about 4:1:2, the exact opposite of what
roses need for maximum rose production.

Those ratios would lead to maximum leaf production.

My 2 cents worth.
