I admire your ambition. I am very unfamiliar with your conditions. Off the top of my head I would not even try to do succulents with the humidity and rainfall you have. Back when I was learning about summering my cactus outside I had to use Preen in the pots to keep the grass seed blown in the wind from sprouting. We only get something like 35" of rain a year. If you can keep the rain off your succulents you might have a chance. With your Winter temps I would imagine they will all go dormant and need no water. Gene
