    Dipladenia Features

    🐝 + 🐦: Attracts Bees & Hummingbirds
    These flowering plants are evergreen perennials that are easy to grow. They grow in a shrub-like growth habit with bushy leaves with trumpet-shaped flowers that bloom in the summer to early fall with a variety of colors ranging from red to yellow.
    They are commonly used in pollinator gardens because they produce fragrant flowers that attract pollinators like bees and hummingbirds. They also thrive in full sun and are drought tolerant making them a favorite due to their low maintenance watering requirements.
    They also make for great container plants as a spiller or thriller.

    When & How to Plant Dipladenia

    🌻: Transplant in spring after last frost.
    When growing outdoors, if you’ve just purchased a young dipladenia from your local garden center, the best time to transplant your seedlings is typically in the spring after the sign of last frost. This will ensure you get full blooms by midsummer to early fall.
    Pro Tip Icon
    Find a bright, sunny spot to plant your Dipladenia.
    Since Dipladenias prefer at least 6-8 hours of bright sunlight a day, you’ll want to find a sunny spot in your garden. Since these tropical vines love to climb, you can also plant them near a fence or a trellis. This will also shield them from any rough winds.
    When you’re ready, dig a hole up to 8-10 inches in depth creating loose soil around the hole to allow roots to form. Place your seedling in the hole and backfill with soil. You can also amend with organic mulch, compost, or peat moss to encourage moisture retention and nutrition.
    You will want to space your transplanted seedlings about one foot apart to allow enough room for the plant to develop.
    After you’ve planted your seedlings, make sure to water them deeply to allow the transplants to settle in.
    If you’re growing in a pot, dipladenia can stay in the same pot for a long period of time. They are resilient plants and prefer being pot-bound.

    Companion Planting: What to Plant with Dipladenia
    Dipladenias grow best with other annuals or perennials that love full sunlight like Fox Tail Fern, Ipomea, Ixora, Sweet Potato Vine, Annual Phlox, and Bidens. In containers or planters, they pair well with Sansevieria and Sweet Potato Vine for a solid thriller-filler-spiller combo.

    Dipladenia vs. Mandevilla: What’s the Difference?

    Dipladenia belongs to the Mandevilla species. But their growth pattern is different. 
    Mandevilla vs. Dipladenia - What's the difference?
    Image Source:Dipladenia is subspecies of Mandevilla, but they do differ in their appearance and care. Dipladenia prefers growing in hanging pots while Mandevilla is more of a climber. Dipladenia is hardy and enjoys full sun.

    • Though both Dipladenia and Mandevilla are vines, the way the vine grows is different. Mandevilla is a climbing plant that grows vertically -- great for polls and trellises. In contrast, Dipladenia is a bushy plant that grows down and hangs from the pot. 
    • Mandevilla plants have larger flowers, whereas Dipladenia has small flowers. 
    • Mandevilla prefers partial sun and fairly low maintenance. Dipladenia are super hardy plants and can enjoy hot, full sun and even take some wind! Dipladenias are drought and heat tolerant.
    • Dipladenia leaves are delicate and pointed and comes in dark green color. On the other hand, Mandevilla leaves are broad and large in size. 

    How to Care Dipladenia

    The growing season of Dipladenia is summer to early fall. During this season, you should give proper care to ensure that the plant gives a full bloom. You can have a garden full of Dipladenia flowers through propagation and proper care. Let us look at the proper care to be given to Dipladenia for its healthy growth. 


    The peculiarity of Dipladenia is that it can tolerate some amount of dryness. Thus, providing one inch of water per week is enough for the plant. As a general rule of thumb, let the top few inches of soil dry in between waterings.
    If you’re growing outdoors, make sure you let the soil dry out after rainfall before watering again. Having consistent wet soil is not good for the plant and can lead to root rot and other fungal diseases.
    It’s important that you follow a proper watering schedule and plant your Dipladenia in well-draining, but moisture-retentive soil. If you’re planting in a container, make sure that it has drainage holes to wick away excess moisture and prevent wet feet.

    ☀️ Light Requirements

    Dipladenia requires 6-8 hours of direct sunlight for healthy growth. But in a sweltering climate, you can provide some light shade.
    If you are growing the plant indoors, you can keep it on a sunny window sill where ample sunlight is available. We recommend placing your Dipladenia near a South-facing window that receives the most amount of bright sunlight a day. You can also consider West or East-facing windows which receive bright to moderate light for half of the day. Avoid North-facing windows as they receive the least light.
    You can always supplement with grow lights indoors if you don’t have much light.

    🌡️ Temperature and Humidity

    🌎: USDA ZONE 9, 10 ,11, 🔥: ~65+ degrees Fahrenheit
    Dilpadenia requires a warm climate for its growth. Thus, it grows well in USDA hardiness zones 9 to 11. The plant requires a daytime temperature of above 70 degrees and a nighttime temperature between 65 and 70 degrees. 
    Dipladenia can grow in humid conditions, but humidity is not very important for the plant’s growth. However, you should take care to maintain a temperature above 70 degrees during the daytime. 
    If growing outdoors, placing Dipladenia in a greenhouse would make a suitable location. It’d also be ideal for overwintering.
    Overwintering Dipladenia: Protect during cold weather.
    If the nighttime temperature falls below 50 degrees Fahrenheit, it is best to protect the plant with a frost blanket. In the case of extreme winter, you can bring the plant indoors. Place it in an area where sunlight is available so that it can survive the late winter cold.  
    You can place it again outdoors once the dangers of the last frost have subsided in mid to late spring depending on your region.

    🌱 Soil

    Diplaneia requires sandy or loamy well-draining soil. Well-draining potting soil is more than adequate for the plant.
    If you use regular garden soil, mix it with some agricultural soil before planting. You can also amend your potting mix with peat moss, sand, or perlite to encourage drainage.
    For container plants, you should change the soil every year to keep up a healthy and bushy appearance of your Dipladenia. Ensure that the container is large enough to accommodate the root ball. 

    🌻 Fertilizer

    You should fertilize Dipladenia with liquid plant food during its blooming period. This helps the plant produce more flowers. A fertilizer with an NPK mix of 10-30-20 is ideal during the flowering season. It is best to re-pot the plant every growing season to ensure consistent fertilizing. 
    You can also opt for manure tea or compost to provide more organic nutrition.

    ✂️ Pruning and Training

    To promote new growth in the plant, you should pinch off a few inches of the plant above the leaf node. Once the flowers die, you should deadhead them to encourage new growth.
    You can slowly train them if you want to grow them on a trellis. But it would be best if you pruned the ends that droop downwards. 

    Propagation from Cuttings

    Cutting is the easiest way to propagate the plant. When propagating, always make sure to check whether your Dipladenia is patented. Commercially patented dipladenias are not allowed to be propagated, especially for commercial or re-seller use.
    When you're ready to propagate via cuttings, follow these steps:


    Wearing garden gloves and using sterilized shears, cut 4-6 inches of the plant below a leaf node. 


    Remove the leaves and flowers from the bottom part of the cutting. Dip in rooting hormone if you have some.


    Plant your new cutting into a small pot with an appropriate, well-draining potting mix with perlite or vermiculite. Deeply water after planting.


    Place in a well-lit, warm location. To encourage humidity and warm temperatures, you can wrap your cutting with a plastic bag.


    After roughly three weeks, when your cutting roots, you can transplant into a new container or outdoors.

    Propagation by Layering

    In this propagation method, the new plant is fed all the nutrients by the parent plant until it grows on its own. It typically requires you to bend the vine down so that it contacts the soil in order to root or you can take the path of air layering.


    Always wear garden gloves and use sterilized knife or shears. Find a stem that you can easily bend to meet the soil (lower part of Dipladenia). Sand or a small cut halfway into the plant’s stem around the stem. Do not detach the stem from the parent plant. 


    Apply rooting hormone to the cut area. This allows a new plant to grow from there.  


    Bury the cut area in the same soil as the parent plant. Keep a stone on top of the soil to prevent the stem from popping out. Once the root appears in the new plant, you can remove it from the parent plant. 
    If air layering, cover the cut area with sphagnum moss and plastic wrap. Wait for it to root after 2-3 weeks and then cut below the rooted portion and replant into a new container.

    Propagation from Seeds

    Propagating Dipladenia or Mandevilla from seed is fairly easy and is best done with fresh seed pods. You will want to allow the seedpods to dry before removing them off of the mother plant. Once seed pods are dry, they will turn brown and being to split open revealing fuzzy seeds which can be collected.
    Once you collect the seeds, soak them in water overnight before sowing them in well-draining soil with perlite and/or vermiculite. Plant them 1/4-1/2 inch below the surface and keep in a humid, warm environment. Use a seed heating pad if one is available. Place them in a spot that receives lots of bright sunlight such as a South-facing window.
    Similar to cuttings, it'll take 3-4 weeks for the seeds to germinate.

    Common Dipladenia Disease and Pests

    Dipladenia plants requires proper care to protect them from disease and pests. Here are some of the common problems and how you can overcome the same. 

    Leaf Spots & Botrytis

    Leaf spots are fungal infections that appear in warm and wet conditions. These are brown or yellow spots that grow to form more spots on the leaves. The best way to control leaf spots is to prune the leaves before the disease spreads. You can also use fungicide spray or neem oil to control the disease. 

    Botrytis, also commonly known as gray mold, is a condition in which the foliage turns brown and wilts. It is caused by water molds that grow in cool temperatures. The best way to control this disease is to spray copper fungicide or a neem oil treatment all over the plant. You can reapply the fungicide every 7-10 days. 
    You want to also ensure your space has enough air circulation and that you've given enough spacing between your dipladenia and surrounding plants.

    Powdery Mildew

    These are powder like mildew that appears on the Dipladenia vines. The fungus spread fast through the wind. The best way to prevent this condition is to provide good air circulation. Placing the plant in full sun also helps control powdery mildew. 

    Fusarium Wilt

    This is a fungal disease caused by Fusarium oxysporum that grows in warm and wet conditions. It causes the foliage in select sections to wilt off. The main drawback of this disease is that you can save the plant only when the condition is diagnosed in the early stage.
    If diagnosed later, you need to remove and dispose of the plant as the condition is not treatable. 
    If you catch Fusarium wilt early, you can spray with a fungicide like myclobutanil, triadimefon as soon as you notice symptoms.

    Root Rot

    Root rot is a condition that causes the rotting of the plant’s root usually due to overwatering or clogged soil. The main sign of root rot is a mushy vine base, slow growth, leaf drop, etc.
    Repotting in well-drained soil or replanting Dipladenia after trimming away rotting roots with sterilized scissors is the only way to save the plant.

    Spider mites, mealybugs and aphids are a few pests that grow in the Dipladenia plant. All these pests feed on the sap of the vine and leaves. This weakens the plant and affects its ability to produce more blooms. 
    To get rid of the pests, you should first spray the plant with a strong stream of water from a sprayer. Once the plants are cleared off the pests, spray insecticidal soap or neem oil every 7-10 days until the problem is resolved. Always remember to wear gloves while spraying insecticide.
