I got several Pels from a co op last year, and managed to keep most of them alive through the winter. I hadn't really tried my hand at Pels, I used to think of them as too common, but have done a turn around on lots of plants as I've gotten older. I'm loving them now, especially some of the modern varieties with mottled and variegated foliage.
I used MG potting soil, and added some grit and fine mulch to give it sharper drainage. I added some Osmocote this spring when repotting them and that seems to have made them happy. They're all in clay pots, and this year I've got them in quite a bit more sun than last year, and I'm seeing lots more blooms.
Vicky, are those in the hanging baskets ivy leaved? I have a bit more trouble with those.
