I am in Temecula and have an ADPM in a large pot, w it trained around a stucco column under my front porch (frost protection). It is evergreen, although it does drop some leaves & gets a little bit raggedy/yellowish & no blooms when it is very cold. As soon as warm weather returns in spring, it perks right up though. Hint: When the temps dip, be sure it is kept on the dry side, AND keep it out of frost (ie under an eave or overhang). It will not survive cold and wet (root rot will set in) Becky

I have my Mandevilla outside the greenhouse. Pruning is up to you.

I prune mine back when I bring it inside for the winter, so I can't imagine that it will be a problem to prune yours relatively hard. Mine have regrown from stem buds.

Hello! I live in coastal southern California's Zone 10. I have a pink mandevilla vine (not sure whether it's possibly a pretty pink or an Alice Du Pont), that's a little over a year old, in my balcony. I had bought the vine during fall of last year, and brought it with me when I moved to my new apartment. It already had about 3' long branches when I moved it into my new balcony, and it grew and bloomed profusely over the last year. Right now, it has 6'-8' long branches everywhere, and looks quite messy. My question is, can I prune the branches back close to the ground, maybe a foot from the base? That way, I can better train them when they grow back, and I also want more branches to grow out from the base itself. But I don't know whether this would be okay, since it would mean trimming into old wood. Would really appreciate any suggestions!
