How To Grow Mandevilla Vines

How To Grow Mandevilla Vines
Mandevilla are vining tropical plants that boast phenomenal flowers in red, pink, and white. Mandevilla Vines are native to the southwestern United States, Mexico, Central America, the West Indies, and South America.
 
These spectacular bloomers are immensely popular throughout the US as a patio plant. They don’t tolerate freezing temperatures but can be grown almost anywhere as an annual or a perennial that you move inside in winter.
 
These climbers look stunning growing up a trellis, arbor, mailbox, balcony, or front porch or flowing over a hanging basket. If you have a sunny spot indoors a mandevilla can make a beautiful houseplant.
 

Mandevilla Vines Care

Mandevilla Vines can be grown outdoors in the ground in zones 9 to 11. In zone 9 they usually go dormant or semi-dormant in winter where in the most tropical growing zones they tend to be evergreen. For cooler zones mandevilla can be grown as an annual or in a pot to be moved inside in winter.

These plants thrive in hot, sunny climates. Plant them in full sun for the most abundant blooms.

They are adaptable to any well-drained soil. Allow the soil to dry out between waterings. Mandevilla Vines likely a slightly moist soil, but do not tolerate wet soil.

Prune your plant back anytime to control growth and promote a bushier habit.

Feed your plant with a slow release fertilizer in spring.

Overwintering Mandevilla Vines

When temperatures are getting close to 50 degrees F it is time to move your vine inside.

Be sure your plant is free of pests. Some safe and easy options if you aren’t sure are neem oil and insecticidal soaps. (You can make your own soap spray by adding a few drops of Dawn dish detergent to water in a spray bottle.)

Cut your plant back by at least ⅓. If you have a very large plant go ahead and prune it back even more. These plants tolerate heavy pruning.

Place your mandevilla in a sunny spot.

Whether your plant is dormant or semi-dormant you still want to water it, but not as often as during the growing season. Allow the plant to dry out completely before watering it.

*Do not fertilize in winter. Even in climates where mandevillas are evergreen year-round they still do through a semi-dormant resting period in winter where they don’t flower and grow slower. So give your plant some much needed rest so it can explode with growth in spring.

Overwintering Mandevilla Vines

A mandevilla can thrive as a houseplant, but you will need a nice sunny spot, preferably a south facing window, in order to get flowers indoors. If you don’t have a bright spot you can purchase a basic plant light.

Make sure your container has good drainage and isn’t much larger than the pot it came in.

Water your mandevilla vines when the soil becomes dry to the touch. (Checking down 1 or 2 inches into the soil with your finger is ideal.)

Feed twice yearly with a slow release fertilizer preferably in early spring and mid to late summer.

Pinch back or trim new shoots to encourage a bushier shape for your indoor mandevilla.

Move your plant into a slightly larger pot when the roots start to fill the pot. Signs of this are roots growing out of the drainage holes or to the soil surface and an inability to hold water as the roots takeover the soil.
