Wintering mandivilla vine

Yes, yes, & no. :) Here's an article to read about bringing them in. The second option listed in this article is really not good in MA weather.

Good luck!

Re-pot in the next size container with fresh soil,spray the entire plant down with horticultural soap.Keep the soil moist not saturated.Do not prune it as as it over winters some of the will die back.Do not fertilize until next year when it re-adjusts being outside.Keep a eye on it as they tend to get spider mites in the winter months.

the hibiscus needs the brightest light you can provide.the temperature cannot be below 55 ,if you see webbing you will spray it down with horticultural oil

I cut mine back to about 6 in. before it frost. I put the pot in the cool basement. Since I do not have a dark place, I cover it with a black garbage bag. I do not water so the plant will go dormant. Next spring I uncover, water and proceed as if it were a new plant. My vine is now 7 years old and has been beautiful ever year! I live in central Virginia.

I also bring my mandivilla in for the winter. I repot it with fresh soil, then mix according to package directions Dyna-Gro 100% natural Neem oil, I first spray it, including underside of leaves, then water it with remaining Neem oil, as it also works systemically. Neen oil is a insecticide, fungicide, & bactericide all in one & is completely organic. Then put it in a sunny window & water it as you would a house plant. 3-4 times during the winter water it with the Neem oil, that will keep the spider mites away. Happy over wintering.
