Your pudica blooms are lovely. My pink pudica is finally blooming this week, almost 2 1/2 years from when it was 1st planted. My new fertilizer mix that seem to have gotten the plants blooming was 1 tbs of MG and 1 tbs of Green Light Super Bloom periodically this summer. I started off with granular Ultrabloom, and some Bayer rose fertilizer when I first brought the plants outside, but I would water them with the MG and SB fertilizer when I watered the brugs, just not as frequently. I'm planning on doing the same thing next year to get these babies going. They'll have to come inside soon, our temps are heading into the 40-50's at night.
I hope that you get a lot more blooms before your season is over.
