MANDEVILLA TRELLIS IDEAS

Whether you have your plants in the ground or in pots, here are some Mandevilla trellis ideas. I’ve grown Mandevilla plants for many years and I’m sharing with you some photos from my own garden.

1. Create a support structure out of bamboo

In this raised bed, I planted some Mandevilla plants in the middle and surrounded them with impatiens. I simply inserted six, 6 foot tall pieces of bamboo into the soil and tied them on top. Super easy!

If you look closely in the photo, I also took clear fishing string and tied them horizontally (like rungs on a ladder) across the bamboo in order to provide additional locations for the vines to climb.

Right after planting, I manually took each vine and gently wrapped it around the bamboo to get it started. Eventually, the plant will naturally wrap itself around the structure.

2. Place a horizontal support between 2 pots to make an arch

In this case, I purchased two Mandevilla pots that already had 3 bamboo stakes inserted in them and tied on top. You can also insert them on your own if your plants didn’t come with them. You will need them for this project.

At this point, I simply laid a piece of bamboo on top to connect the pots, and tied them together securely with twine. Take a look at the photo below.

After 3 months, this is what this setup grew into. The vines completely covered the horizontal bamboo support.

As the plants grow, you’ll have to help them along occasionally by manually wrapping the vines around the support, and tying them if needed.

3. Grow up a post and use fishing string for additional support

In this example, I have another Mandevilla plant with bamboo stakes inserted into the pot and tied on top like in the previous example.

In this case, however, I placed the pot right up again a wooden support of a pergola structure. As the plant grew, I tied the vines with clear fishing string to support and contain the plant.

Once the vines reach the top, I started to train the plant horizontally by using clear fishing string.

You can see in the photo below, I have a pink Mandevilla on either side of the pergola.

In the top horizontal wooden face of the pergola, I simply hammered some small nails and ran clear fishing string along the top.

As the vines grew, I would wrap them around the fishing string. This creates a beautiful floral arch! You can really get creative with clear fishing string.

I hope this has sparked some ideas for your own garden, so get creative! Now let me talk a bit about Mandevilla care and what they like so you can keep them blooming and happy.

MANDEVILLA CARE

Here are some basics of Mandevilla care.

LIGHT

Mandevilla plants are sun-loving, so be sure to give your plant at least a half day of direct sun (more is better) wherever you put them outdoors.

If you have them in too much shade, blooming will be compromised and no one buys these plants just for the foliage.

POTTING MIX

Freely draining potting mixes are very important for these plants. A good mix to use would be 2 parts all-purpose potting mix and 1 part coarse sand.

Excellent, sharp drainage is a must for this plant.

WATER

Regular watering is important, especially during hot, dry, summer days. Always feel the soil though before watering. I like to allow the top couple inches of soil to dry out before watering again thoroughly.

Never water if the surface of the soil still feels moist.

FERTILIZER

Mandevillas grow quickly and need plenty of fertilizer for best performance.

I’d recommend regularly using a good fertilizer like Miracle Gro Bloom Booster for an abundance of flowers all summer long.

TEMPERATURE

When purchasing Mandevilla plants, resist the temptation to buy them when temperatures are still cold. Wait until minimum nighttime temperatures are at least 50°F (10°C) before purchasing them.

ROUTINE CLEAN UP

Remove any spent flowers regularly. Once flowers are done, they often fall off onto the foliage, and can create quite a mess.

In order to keep the foliage in good health and help deter pests and diseases, be sure to regularly remove any fallen, spent flowers from the foliage.
