Propagating Mandevilla: Using Mandevilla Cuttings Or Seeds To Propagate Mandevilla Vine

Mandevilla vine is known for its showy blooms. Largely grown in containers or hanging baskets, this tropical vine is generally treated as a houseplant, especially in cooler regions. In southern climates, it can be set outdoors in spring but returned inside prior to winter. Learning how to propagate mandevilla is easy. Mandevilla propagation is accomplished by seed or cuttings.

How to Grow Mandevilla Seeds

Propagating mandevilla from seed isn’t difficult, though it is best achieved with fresh seeds. Seedpods should be allowed to remain on the plant to dry before removing them. These can be easily recognized by their inverted v-shaped appearance.

Once the mandevilla seed pods have dried, they will turn brown in color. They will also begin to split open, revealing fluffy, dandelion-like seeds. At this time the seeds are ready to be collected.

For better results, soak the mandevilla seeds in water for about twelve hours prior to sowing them in well-draining soil. Mandevilla seeds require shallow planting, only covering them slightly with soil. Keep these moist and warm (about 65-75 F./18-24 C.) and place them in bright, indirect light. The seeds should germinate within a month or so.

How to Propagate Mandevilla Cuttings

Mandevilla vine is very easy to propagate from cuttings. While the best time to take cuttings is in spring, you can also take them in late summer or fall with some success. Cuttings should be made from tips or side shoots and about 3 inches (7.5 cm.) long. Remove all but the top two leaves. If desired, dip the mandevilla cuttings in rooting hormone and then stick them in a sandy peat mix.

Place the mandevilla cuttings in a somewhat shady area and keep them warm, moist, and humid. In fact, it may be helpful to place them in a plastic bag (with small air holes to release excess moisture). Once roots develop within a month or two, you can pinch back new growth to promote bushier growth if desired.

Mandevilla propagation is just that easy. Now that you know how to grow mandevilla seeds or root mandevilla cuttings, you can grow this lovely vine year after year.

Mandevilla is one of my favorite container plants.
I have had this one for years – so long that I can’t remember when I got it. I love the tropical look. It reminds me of Hawaii.

Many people buy a new one every year, not realizing it will keep through to the next year. I’ve done this two ways. With both methods the important thing is to bring it in before the first frost.
Method 1 – Put it in a crawl space or basement for the winter and forget about it. The plant goes dormant. It looks dead. Then in the spring, even though it was never watered, little pale green shoots start coming out. After the last frost, put it out. At first, put it in a less visible location. It’s not exactly pretty at this point. Then sometime around June, put it where you want it to stay for the rest of the summer.

Method 2 – In our new house, we have lots of sunny south windows. The last two years I brought the mandevilla inside before the first frost and put it in front of a sunny window. The first year, I was hoping it would bloom all winter. It didn’t. But it did stay green. When I put it out in the spring, it wasn’t as unattractive as with method 1, so I didn’t need to hide it away. It flowered just a little sooner than with method 1. If you use this method, it is recommended that you cut the plant way back to about 12 inches. I didn’t do that these last two years, but this year, I will. Note: If you don’t have room in your house, some people have had luck putting the plant inside of a clear plastic bag and placing it in their garage.
It does best in a location that gets plenty of sun. It can take full sun, but is also fine with a little shade.
It will need something to climb. I usually put it near a fence or rail. My pot has a trellis in it as well, but I didn’t pinch back so it outgrew the trellis. I wanted it to climb up my deck rails – and it did as you can see in the photo. You can (and should) pinch off shoots to make a bushier plant. That won’t affect the flowering. Next year, I’ll probably put it in a different location and I’ll pinch it back to keep it short and bushy.
Sometime around June or July, it will begin to flower. When the heat of summer is cooking everything else in sight, the mandevilla is happy as can be.
I have thought about getting another mandevilla, but they have become fairly pricey. I love to propagate plants from cuttings so it should have occurred to me that I could do this with the mandevilla. Then last week, while looking up something on the computer, I came across an article on rooting mandevilla. Yippee!
I got three little starters by cutting the tips off three new growth branches on the plant I have. I put them in a very beat up pot which I hope to soon place inside of something more attractive. What can I say? I was in a hurry. According to what I read, I need to keep in a shaded area and keep it moist and humid. It will take 20 to 70 days to root. When it looks like it’s growing, I’ll move it to a brighter location. Hopefully, it can be put into a larger (and nicer) pot in the spring. We’ll see. This is my first time rooting mandevilla. I hope to get a few more cuttings started in the next few weeks.

Saving Container of Mandevilla Over Winter

I received a Mandevilla vine for Mother’s Day. It is growing outside in a large container on a chainlink fence. I know it is not hardy in my area and would like to save it for the winter. But I don’t have room for this big container. Is this possible?

Mandevillas are difficult to propagate. Take 4 to 6 inch long cuttings in summer. In the future try taking softwood cuttings in spring to increase your chance of success. Let the cuttings dry for an hour. Stick them in water over night. Next dip them in a rooting hormone and place in moist vermiculite, perlite or peat moss mixed with perlite or vermiculite. Loosely cover the pot with a plastic bag and keep it in a warm location out of direct sun. Plant rooted cuttings in a well-drained potting mix. Grow these small plants as houseplants throughout the winter. Artificial lights will increase your chance of success. Those with smaller containers can move their plants indoors for the winter. Grow the plant in a sunny window or under artificial lights. Keep the soil moist but not wet. The plants usually lose all their leaves while adjusting to their new home indoors. They will soon sprout new leaves and the plants will struggle through the winter indoors.

Dipladenia (dy-pla-DEE-nee-uh) the rocktrumpet or Brazilian jasmine is an older classification for plants now commonly falling under the genus Mandevilla.

The difference between Dipladenia and Mandevilla is in their growth habit.

The spring favorite Mandevilla vine has a vertical growth habit. The Dipladenia plant is a bushy plant with downward, hanging growth.

Dipladenia is an evergreen, flowering plant and a member of the Apocynaceae family (Dogbane).

These flowering tropical vines originate from Brazil – specifically Rio de Janerio and is found in South and Central America, Southwest United States, West Indies, and Mexico.

The most popular species is Dipladenia sanderi (Mandevilla sanderi). It is a woody climbing plant with shiny, opposite, elliptic leaves, trumpet-shaped flowers, pink with orange throat.

The bright, colorful appearance and attractive growth habit make the Dipladenia plants an ideal choice for your garden or as a houseplant.

Dipladenia Plant Care

Size and Growth

Due to its tropical nature, it can flower for most of the year even in cooler areas.

But it will have a shorter flowering period in such temperatures.

Dipladenia bush, has an upwards growth to a certain level after which it droops over the side of pots or hanging baskets and begins to trail downwards.

You can train your plant to have a bushy growth by giving the plant support at the base and pinching out new growth.

Encourage the climbing growth habit by winding the plant around a taller structure like a trellis as it grows.

Rio Dipladenia is a hardy plant and recommended for USDA hardiness zones 10 to 12. It can also be overwintered indoors.

Flowering and Fragrance

Dipladenia Rio plants are bushy plants characterized by small, pointy leaves with a slight, gloss-like sheen to them and are a shade of deep green.

It also has smaller, tube-shaped flowers in comparison to Mandevilla flowers that blooms in a number of different colors ranging from pink and red to orange with a soft fragrance.

Light and Temperature

Rock trumpet plants are not one to shy away from the full sun. However, in extremely hot climates they will benefit from some light shade over direct sunlight.

If growing dipladenia flowers indoors keep the plant in a sunny window.

It is not a very cold hardy plant. It requires warmer temperatures ranging from 65° to 70° degrees Fahrenheit.

It can be overwintered indoors if the temperatures are falling too low.

Watering and Feeding

These tropical plants require frequent watering in the summer months. Be careful not to overwater or else you will risk root rot setting in.

Let the soil dry out between watering and apply a layer of mulch for extra drainage.

This plant is also tolerant of some occasional droughts due to the roots’ ability to store water.

Dipladenia does not require a lot of feeding. Feed with a slow-release fertilizer in the early spring.

Or feed once or twice a month at most during the growing season using a good liquid plant food.

It should not be fed during winter.

Soil and Transplanting

Mandevilla Dipladenia will require a good, well-drained potting soil.

A potting mix with good insulation and moisture will keep the plant from needing frequent transplanting.

When transplanting Dipladenia Mandevilla, try to retain as much of the roots as you can.

If transplanting a fully grown plant, ideally use a larger container, so the plant has more space to grow.

In the case of transplanting in the garden, the hole should be as deep as the plant’s root ball but much wider.

This allows the roots ample space to spread.

Grooming and Maintenance

Cutting back the tips of plants will encourage them to have a bushier growth.

This should be done when the plant is not in full flowering mode.

Late winter or early spring is best.

How To Propagate and Grow Dipladenia

Dipladenia propagation is done from vine cuttings.

  • Remove a mature vine and strip off the leaves around it.
  • Wash off the sap that may leak from the cutting
  • Dip the cut vine stem into rooting powder
  • Once the cut drys, place it into a prepared container or pot.
  • Position the newly planted vine in a warm location with plenty of light.

If outdoors, a greenhouse is an ideal location or an eastward facing window if it’s being kept indoors.

Make sure to keep the soil moist by spraying it lightly until the plant takes root.

Dipladenia Pest and Disease Problems

Dipladenias are susceptible to spider mites and aphids.

These can be handled through spraying insecticide soap on the pests.

There is also a chance your plant will develop fungal diseases.

These can be handled fairly easily by using a fungicide to contain the spread.

Be careful when handling Dipladenia as their vines contain a skin-irritating sap.

Wear gloves while handling the plant.

Suggested Dipladenia Uses

Rio flowers are great plants to use both as an ornamental indoors plant or as a garden accent for container gardening.

Its bright colors are conducive to attracting hummingbirds and bees.

Mandevilla, now botanically known as Dipladenia, is a popular vine with shiny green leaves and trumpet shaped flowers in red, white, pink, yellow or apricot. This tropical vine is only hardy in frost-free areas. That means the rest of us need to overwinter it indoors if we want to save the plant for next year’s garden.

If indoor growing space is limited, consider taking 4 to 6” cuttings. Dip the cut end in a rooting hormone and stick it in moist vermiculite or a well-drained potting mix to root. Then plant it and grow it like a houseplant.

Or move the whole plant indoors in front of a sunny window and grow it like a houseplant. Water thoroughly when the top inch of soil is starting to dry.

A third option is storing it in a cool dark location. Water just often enough to keep the roots from drying out.

A bit more information: Be sure to quarantine any plants you move indoors before adding them to your indoor garden. Monitor the plants for several weeks, watching for any pests that may have hitched a ride inside on the plant.
