Soil & Fertilizer
Rio Dipladenia does well in well-draining, loamy, and sandy soils. General houseplant potting mix works well. Preferred pH levels are 6.5 to 7.5.
You should feed it fertilizer every two weeks. The best fertilizer to use is an all-purpose houseplant fertilizer. Don’t fertilize the Rio Dipladenia in the winter, as this is the plants resting time.
As the plant can tolerate drought, it won’t be a big deal if you forget to water it for one or two days. You’ll know when to water by touching the soil. If the first two inches of the soil are dry, then you can water it.
Do let the soil dry out between watering. Some of the leaves might die but the plant will grow new ones in the summer.
The Brazilian Jasmine can survive any season outside, except for winters when the degrees may drop below 45 °F (7 °C). You can bring the plant inside to protect them from frost. Bring the plant indoors before frost to overwinter. Rio Dipladenia can grow outside during winter in USDA Hardiness zones 9-12.
You can take the plant back outside after the frost has passed. If the leaves start turning yellow, then the climate is too cold for it. The yellow leaves will fall off and new healthy leaves will grow instead.
Propagating Rio dipladenias is not difficult, here’s how to do it via stem cuttings:
- Choose a mature vine, then cut it off with a slant cut.
- Remove the leaves around the lower half
- Dip the lower part in the rooting hormone to speed up the root formation.
- Plant it in potting soil and water it well.
- Place it in a place with plenty of sunlight and warmth.
- Roots should develop in 3 weeks
An important part of caring for the Rio dipladenia is repotting. This flower should be repotted every spring. Increase the pot size only by one, when repotting. If the plant gets repotted into a pot that’s too big, then it’ll spend more time growing roots and less time growing flowers.
It’s best to prune the plant in very early spring to spur on blooming. Pruning can also be done after repotting. Best to use clean and sharp scissors. To maintain its size, cut back all the flower shoots from the main drive. Don’t forget to cut near the base.
The biggest issue with Rio Dipladenia can be root rot. If the soil stays very wet, you can see white mold on the top layer. If leaves have brown spots on them and stems turn blackish or brown, root rot is possibly the explanation.
In this case, stop watering and change the substrate if the plant is in a pot. Use a fungicide that contains copper. Dilute the fungicide in 15 liters of water before use.
If white or grayish mold appears on the leaves or flowers, then the best thing to do is to cut the infected parts off with disinfected sharp scissors and apply polyvalent fungicide.
Rio Dipladenia can be affected by mealybugs, scale insects, spider mites, and whiteflies. Although this plant is a tough one it can still attract these pests. Best to keep an eye on the plant to spot the pests early.
To get rid of these pests you can spray the plant with neem oil or with insecticidal soap. After spraying the plant keep an eye on it. If the plants’ leaves are still turning yellow and dropping do spray them weekly until it’s healthy again.
Rio Dipladenia is an easy-to-care-for plant that will brighten up any room, office, or garden. It’s perfect for a beginner to care for. The varieties of colors make it easy to fit into any scenery. This plant will bring out the magical yet elegant aspects of any environment.
