Planting, Growing, and Caring for Mandevillas

With huge tropical-looking flowers and evergreen glossy foliage, flowering mandevilla vines are perfect for a trellis, arbor, or post. While the plants are only cold-hardy in zones 9 and warmer, these brightly-hued blooms are enjoyed as annuals in the rest of North America.

Today, mandevilla comes in two types: climbing and mounding. 

  1. Climbing mandevilla is a traditional tropical vine with long tendrils that wrap around a column to create bright colors around any vertical feature.
  2. Mounding mandevilla is perfect for large containers on your deck or patio or bringing splashy color to garden beds. They have all the beautiful colors and tropical vibes but are semi-upright.

These bright beauties will provide colorful blooms from summer until frost. You can also bring them indoors for the winter if you wish.

They are easy to care for and need little maintenance. As long as you give them what they need (as described in this guide), they provide big results with little effort.

Most mandevillas are grown as annuals in pots. Select a location with full sun, protection from the wind, and, for climbing types, something nearby to swarm up. Good drainage is necessary. If planting mandevillas in the garden, soil pH should be slightly acidic to neutral. 

When to Plant Mandevilla

How to Plant Mandevilla

Mandevilla plants are normally grown in containers except in the far South, and many of us won’t bother moving them from the pot we bought them in at the nursery. 

If you transplant them, either to another pot or into a garden bed, treat them like any other large plant.

  1. Water thoroughly a few hours before transplanting.
  2. Gently rock or squish the sides of the container to help the roots release.
  3. Cut any circling or girdling roots, and score the sides of rootbound plants to aid growth.
  4. Use fresh, well-draining potting mix, or prepare the garden bed with some finished compost worked in.
  5. Transplant the mandevilla, keeping the depth at the same level on the plant as in the old container. Firm up the soil and water again. 

Don’t forget the stakes or trellis if that is what it will climb. Putting them in at planting time is much easier for you and the plant than waiting until it has sprawled all over and is asking for help. 


Mandevilla, especially the long vining types, are excellent climbers, but you can still help it find the trellis or arbor. Use biodegradable twine and tie a loose loop around the support and the vine, then gently twist the vine around the support structure. Tie a loop with some extra space, and you won’t have to remove it later. 

Mandevilla enjoys moist soil, but allow the top inch or two to dry out between waterings. Too much water can provide ideal conditions for root rot, even in tropical plants.

A general-purpose or bloom-booster slow-release fertilizer applied in early summer will meet any feeding needs for the season. 

Overwintering Mandevilla

Mandevillas can be expensive, and buying new ones every year adds significantly to the cost of the spring garden center run. Fortunately, with some care, you can overwinter these beauties and enjoy them again next year.
Mandevillas have a natural dormant period from late fall into April. They’ll stop growing and may even drop their leaves, but don’t panic.

You’ll want to give your mandevilla a pretty drastic haircut before bringing it inside for the winter. Trim it back to about 12 inches from the base. It will look like savagery, but the alternative is cleaning up all that mess inside your house when it gets dropped anyway.

Once you’ve trimmed it back with your clippers, bring it inside and store it in a basement, garage, or other cool location. You’ll need a location that doesn’t dip below about 45F. If you don’t have one, you can store it in an out-of-the-way location in the house, but the cooler, the better. 

In mid-spring, bring your mandevilla out of storage and place it in a warm location with bright light. A sunny south-facing window will be fine. Check the soil moisture and add water if dry, but don’t go overboard. The plant takes a while to “wake up” and won’t use much water until it does.

Set your mandevilla back outside when all danger of frost has passed, and nighttime temps are warming up. Wait to fertilize until you see growth starting again.

Wit and Wisdom
  • Mandevilla and Dipladenia are often confused, and they look very similar. The gist is that mandevillas are upright climbers, and dipladenias are trailers–they grow down and are more suited to hanging baskets.
  • When pruning mandevilla, wear gloves. The milky sap is a bit sticky.
  • Tall mandevillas can act like sails in heavy wind. If your mandevilla is portable, such as in a container, move it to a more sheltered position before high winds or storms.
