I've been using Miracid 30-10-10 on my Sarracenia every two weeks for the past 2 months. My flava are making leaves continuously. They are larger and larger. Usually the plants just make one or two flushes of pitchers for me, the first flush being the largest. Scarlet belle is making larger leaves too.
I use 1/3 teaspoon per quart in a sprayer. I mist to wet the leaves being careful not to make puddles on the lids or run off any into the media.
