Pam, I use Miracid because of it's higher nitrogen content (30-10-10). I've read some University studies that lead me to believe that a high Phosphorus/Potassium level is not necessary to increase flower production (Jeff Gillman Un. of Min) contrary to what some fertilizer manufacturers might advertise. Since daylilies are in pots that are continually watered, a renewal of their depleted nitrogen is nescessary however. So even though I start out with Osmocote Plus (with minors) in the spring, it has improved the performance of my container plants (including roses) to periodically water in Miracid at 1/2 strength throughout the summer when watering is at it's peak. The acidic properties in this small supplimental dose of Miracid aren't so overwhelming that it affects the plant growth. My private blend potting soil tests out at a 6.6-6.8 Ph btw....The answer is then, that Miracid works better then Miracle Gro for me mainly because of a higher nitrogen content (the micros in Miracid are an added benefit).....Hope that makes sense.....Maryl
