Donald, do you overwinter your mandevilla 'Alice Dupont' in the ground? I did so successfully last year here in zone 8a. But have yet to cut it back this year or to mulch it, as it's still blooming. But we might get frost this week, so I'd better get that done tomorrow. As for my dipladenias, they come indoors or stay dormant in the garage over the winter. I nearly lost mine last year, as I don't think it liked being kept dormant in the garage. So, I'm bringing all dipladenias inside.
