Frilly, this is my 2nd year with Do Tell and my first year with blooms (4 blooming stems, so not bad). I found it faded fairly quickly too, but mine is in full sun with strong afternoon sun.
Jason, I've just jumped on the alfalfa bandwagon and been using it on my roses. Too soon to see results, but I've heard enough positive reports to convince me to try. Hadn't used it on peonies yet, but will certainly give it a try!
