Answer: A gro-light would certainly remedy the lack of sunlight for your mandevilla. Keep the light on 14-16 hours a day and your mandevilla should grow and bloom as if it were outdoors in a tropical paradise. Since you've recently dug your plant and taken it indoors, it is probably going through an adjustment period (different temperatures, humidity and light). You can prune it back, keep it in damp but not wet soil and place it under (or near) a grow light and it should perk right up for you. Best wishes with your mandevilla!
