Q.Survival Of Dipladenia After One Night Of 32 Degrees.

Zone 55391 | Anonymous added on October 23, 2021 | Answered

My dipladenia suffered through one 32 degree light frost. We brought them inside within a few hours; leaves dried up but soil not frozen. If we remove all dead leaves and cut back stems, will it regenerate in a 70 degree environment in a southwest window?

It won't hurt to try. You can check for stem damage by scraping off some of the stem. If it is green below, the stem survived, but if not, trim till you reach green stem. If needed, you can cut it all the way back to about 6 inches. Water sparingly for the winter and hopefully, you will see some new growth (may not regrow till spring).
