Q.Over Winter My Mandevilla

Zone Toledo Ohio 43611 garden zone 6 | Anonymous added on October 25, 2024 | Answered

I would like to overwinter my Mandevilla into a dormant state but I don’t want to bring the bugs in.. I read you can drench with water but my question is can I just repot it in fresh dirt and cut it back?

Yes, repotting will get rid of any eggs or bugs in the soil. And cutting back mandevilla will reduce any bugs. You may still want to spray the remaining foliage with Neem oil to get rid of anything else. Here is how:
