Black spots on rose shrub leaves, leaves turn yellow, and fall off
We have tried a few different fungicides - is this the correct approach? Please help. Thank you - Stephen Nigro

Several fungicides are labeled for control of black spot on roses. All are preventative, meaning that they must be sprayed before the problem develops. You should also consider growing roses that are resistant to black spot and that would not require regular spraying to remain healthy.
