Question: 325-5201
Is Mandevilla perennial and can I leave it outdoors? Madeline, East Lyme, CT.

Mort's Answer:
It is perennial in zones 9 and 10. In zone 6, you will have to bring the plant indoors in October or earlier, if there is the threat of frost. Mandevilla was named after the minister of Buenos Aires and is native to Argentina. It requires a peaty and sandy soil. It should be allowed to go into dormancy. Cut it back and keep it barely alive , preferably in a cooler spot. Next spring , you can bring it out again. I'm tempted to tell you to cover it in the winter with mulch. We don't have enough information on this beautiful woody vine yet. I would make cuttings from it and try leaving out an older plant, when I have a half dozen to back it up.

Question: 640-4411
What should I do with my Mandevilla for the winter? It is really tall. Bruce, Norwich, CT

Mort's Answer:
Mandevilla suavelons is a tropical woody vine that can get really big outdoors. Unless you have a greenhouse or similar environment, you will need to rest this beauty for a month or two indoors. Cut it back to three to four feet and store it in the cellar until January. If you have a partly heated garage that will work. It needs to be between 40 and 50 for that time. Water the plant just enough to keep it alive. As the days get longer the house plant will start to throw out new shoots. At that time you can add some liquid fertilizer to the water and water more frequently. If you have a greenhouse, you need not cut it back. It is best planted in the ground in the greenhouse.

Question: 942-2113
I got a Mandevilla for Mother's Day. I do not know hope to care for it? Mary, Sophia, WV

Mort's Answer:
This tropical beauty loves heat. You can get best results for this vine by putting it in the ground for the summer. In the fall, bring the plant indoors and treat it like a houseplant. You can also rest the plant by letting it stay in a basement where the temps do not go below 40. Some folks like to keep it in a pot as a patio plant. Those funnel shaped pink and white flowers are quite fragrant. It is a climber but can be maintained as a shrub . You might consider using a trellis if you plant it in the ground.

Question: 1174-4014
I plan on bringing my 12 inch hanging Mandevilla into the house soon. Can it last the winter? Edna, Mansfield, CT

Mort's Answer:
Mandeville can be rested in a basement with very little water to be placed outdoors in the spring. Many folks keep them as a houseplant in a sunny warm place. I would suggest repotting the plant into a two inch larger clay pot for the winter. Use a potting soil with a third coarse sand. I would place it on a small table instead of hanging it for the winter months. You can use a light liquid fertilizer every other watering or a one time tablespoon of 5-10-10. When spring arrives, you will need a stronger apparatus to hold the heavier plant for the spring hanging.
