Well. Monardas are one of the few plants I dont grow.....I know several on the forum do. I have avoided growing them because they are susceptible to mildew. However, I intend to grow a few varieties next year....buy them over winter now.
I do know how to grow them though........they need good soil, soil that doesnt dry out too much and they will grow in sun or light shade. I think mildew is not a problem if you can provide comditions Monardas need.
They are tough hardy plants and should not need protection over winter. I sense though you have tried to grow them in heavy moist soil.....? They will not like that ESP over winter. If you have heavy soil grow them in the sunniest, warmest,spot you,have.
