Hmm, I've used it for years on my own roses, and I think it makes the blooms brighter, although not necessarily more beautiful. I used it in the Garden where I volunteer at last fall, and this spring, as well as using an organic fertilizer rather than inorganic like normal (for this garden anyways), and the bushes look healthier than they did last year, that is, greener leaves, more blooms. In fact, I would say the Garden looks twice as healthy as last year. And there have been more basal breaks. But I don't know if the Epsom salts helped, or the organic fertilizer which I applied twice, once in liquid form, and once just sprinkling it around the base, or because they have been watered most of this summer with a drip system, and probably got more water than before when I hand watered 1-2 times a week.. The water is hard, and the soil perfect as far as not being clayey or having hard pan some of us have in this area.
