Answer: You can cut the vine back to about 6 inches to encourage healthy new growth. Wait until the weather warms - about mid-April in your region - to place it outdoors again. Mandevilla flowers best when it receives 6-8 hours of direct sunlight. It likes moist but not soggy wet soil and can be fed every 3 weeks with a half-strength dilution of liquid fertilizer. Enjoy your mandevilla!
