How to Care for Mandevilla Vines
How to Grow Mandevilla as a Houseplant
A mandevilla vine makes a lovely houseplant if you have a sunny spot. If the light is too low, your plant will produce few, if any, blooms. As an alternative you can purchase a plant light and leave it on at least 8 hours per day. Choose a pot that has good drainage and isn’t more than twice the size of the current container. Water your mandevilla plant when the soil is dry. Fertilize your plant 2 times per year with our slow release fertilizer. Keep your mandevilla vine trimmed by pinching back new shoots to encourage a less vining and more compact habit.
Repot your mandevilla into a larger pot when the roots begin to fill the pot. You will know it is time to repot your mandevilla vine when you notice roots growing out of the drainage holes or up to the top of the soil and the soil becomes unable to hold water as the roots take over.
