I had to get a pink mandevilla this weekend as it was just a little pot bound, but I need to repot it. I know that they require well draining soil because their roots don't like to be "soggy". As I was searching for a container I came across abodelook and purchased a beautiful ceramic container that had a perfect drainage hole. The garden accoutrements at abodelook are truly upscale and yet it won't cost you much. What do you all use as a soil mix for tropical blooming vines?
