Since there are both perennial and annual flowering plants, if you don’t know Rio Dipladenia belongs to which category, it may intrigue you to learn about whether Rio Dipladenia is a perennial plant or an annual plant.
Also, before starting to grow Rio Dipladenia in your garden, another common query of yours can be wanting to learn about how to care for Rio Dipladenia. Therefore, read further to get to learn explanations given for both of your queries.
Is Rio Dipladenia Perennial Or Annual?
Rio Dipladenia is basically perennials that remain evergreen throughout the year in frost-free weather in the USDA regions 9 through 11. However, Rio Dipladenia now can be grown in colder regions like an annual plant in gardens or pots but the plants need to be shifted to safe places during winter.
Naturally, Rio Dipladenias are perennial tropical flowering plants that are evergreen and blossom during all most times throughout the year if they are cultivated or planted in the USDA hardiness regions 9 through 11 and get full sunlight.
Because the average lowest temperature of the USDA zones 9 through 11 is suitable for Rio Dipladenias to grow as perennials.
However, Rio Dipladenias can act like annuals too if they are being cultivated or planted outside in regions with colder weather and in the USDA region 8 where the temperature falls below 45° F.
Because Rio Dipladenia can’t withstand cold and might lose life unless they are properly overwintered in winter.
Rio Red Dipladenia:
Rio Dipladenias are perennial plants that will stay alive and green all year round if you grow them in frost-free weather and provide them with full sun.
But if you want to grow Rio Red Dipladenia in cold regions, know that they will behave as annuals.
Rio Pink Dipladenia:
Just like Rio Red Dipladenias, Rio Pink Dipladenias are perennial plants too and will thrive and blossom all season if they get warm weather. And they will turn into annual plants as well if planted in freezing weather.
Does Rio Dipladenia Come Back Every Year?
As long as you are cultivating or growing Rio Dipladenias in frost-free weather in the USDA regions 9 through 11, they are supposed to be come back every year.
Because while being grown up within these regions and climates, Rio Dipladenias behave like perennial flowering plants.
However, if you have planted Rio Dipladenias in the USDA region 8 and that too outside, they may not come back. As these regions are too cold for Rio Dipladenias to survive so they are likely to lose life unless you overwinter them indoors.
How To Care For Rio Dipladenia?
The caring for Rio Dipladenia should be started with planting the plant in well-drained soil. Rio Dipladenia should be provided with bright sunlight, frequent watering, occasional fertilizing, and a temperature between 65°-70° F at the night and must be overwintered indoors before colder seasons.

You either can fertilize Rio Dipladenia’s by applying a slow-release fertilizer earlier in spring or you can apply a good liquid fertilizer once or twice every month, especially when it is growing season. But don’t fertilize in winter.
Groom For Encouraging Growth:
As a part of caring, you have to chop the tops at the leaves’ offtips to stimulate Rio Dipladenias for having bushier growth.
Late wintertime or earlier in the spring is the perfect time for grooming Rio Dipladenias as they start blooming from June to October.
But never do this when the plants are blooming.
Overwinter Them to Protect:
Rio Dipladenias are not cold tolerant, so to protect them and keep them alive for the next years, you must overwinter the plants by allowing them to stay in dormancy indoors before winter hits the plants.
Keep In A Warm Temperature:
Even at night, Rio Dipladenias need a warmer temperature, thence, try to keep the temperature around the plants between 65°-70° F at night.
Can Rio Dipladenia Survive Winter?
Rio Dipladenias are not likely to survive the harshness of cold winter. Especially, they will not survive in places where the temperature in winter drops below 45° F (7° C) because below 45° F temperature is considered too cold for Rio Dipladenias to withstand.

Do not apply fertilizer on Rio Dipladenia during overwintering time because your goal is to keep the plant alive indoors not growing them.
Overwintering In Dormancy:
Tips for overwintering Rio Dipladenias by allowing them to go dormant.
Prune The Plant:
After transplanting the Rios Dipladenia in another pot in the same way as overwintering indoors, prune back the plant hard and cut about 12 inches of its vines.
Keep Outside Until Becomes Dormant:
You should keep the plant outside as long as it goes to dormancy and the vines get cool, then move to a cool place like your home’s basement or garage.
Keep Temperature Above Freezing:
Make sure that the place you are keeping the plant has a temperature of around 50° F which is above freezing level.
Don’t Water Or Fertilize:
During dormancy, do not water or fertilize the Rio Dipladenia plant.
How Long Does Rio Dipladenia Last?

Rio Dipladenias are mainly perennial flowing plants that thrive the best in frost-free weather, keep coming back every year, and bloom all season long. However, if Rio Dipladenias are cultivated/planted in colder regions, they behave like annuals and require to be
