Magnesium does work well on the roses, though.

Are you suggesting that roses are sensitive to magnesium?


I am saying that when I occasionally put a magnesium sulfate solution
on the soil near the base of the roses that I notice the leaf color
appears to be a darker green and the bloom color is more intense.
(well, on the yellow rose, anyway, I haven't tried it on the others.)

And I only do it once a year.
