Mandevilla - cut back to allow dormancy in house?

graywings123November 7, 2012

I did a search of threads on Mandevilla in this forum and didn't see this addressed, so:

I was given a bloom Mandevilla late in the season for Zone 7 Virginia. I now have it in the house and plan to let it go dormant. Should I keep it as is or cut it back? Will it bloom on these existing vines next summer?

I've never heard of "cutting back to allow dormancy". Plants will become dormant if the temperature is low and/or they are suffering from drought. Pruning will not make any difference. Generally the right time to cut back is in the spring, if you have to, though with Dipladenias (Mandevillas) I find they need very little pruning. If I were you I'd leave it alone. The danger with autumn pruning is that you introduce disease when the plant is in a weakened state. Good luck. - Ian.

Thanks! I will just leave it as is, cut back on water and see how it goes.
