General Caring Instructions for Rio Dipladenias
Planting and Light Requirements
In USDA Zones 9-12, plant Rio Dipladenias at the same depth as in their original pots, spacing them 8 to 12 inches apart. These plants grow 12 to 24 inches tall and bloom best with at least four hours of direct sunlight daily.
Watering and Feeding
Rio Dipladenias are relatively low-maintenance when it comes to watering and feeding. These plants prefer to have their soil dry out between waterings, making them well-suited for gardeners who might occasionally forget to water. During the growing season, feed them every two weeks with an all-purpose fertilizer to support their growth and flowering.
Pruning and Maintenance
No deadheading is needed; spent blooms naturally fall off, allowing new ones to flourish continuously. This low-maintenance feature makes Rio Dipladenias perfect for busy gardeners who want vibrant, easy-care plants. Keep an eye on the overall health of the plant, but otherwise, these hardy plants require very little intervention to thrive in warm climates.
Caring for Rios in Cooler Climates
Rios produce beautiful bright blooms and lush foliage yet are hardy enough to thrive in non-tropical climates all season long, from mid-May to mid-October. During this time, You can take care of your Rios as outlined above in warmer climates. Allow the soil to dry out between watering, and fertilize with all-purpose fertilizer every 2 weeks. Don’t forget, more sun equals more blooms. We recommend a minimum of 4 hours of direct sunlight per day.
The only thing that differs when caring for Rios in cooler climates is that they will need to be brought indoors before the frost.
Overwintering Your Rip Dipladenias
If you live in a cooler climate, particularly below USDA Hardiness Zone 9, your Rio Dipladenia will need some extra attention during the winter months. As the temperature drops, it’s essential to bring your plant indoors to protect it from frost. Place your Rio Dipladenia in a sunny spot, ideally a south-facing window, to ensure it receives ample light. Maintaining a warm environment is crucial, as Rio Dipladenia thrives in temperatures above 45°F (7°C).
Watering and Feeding Your Rios in the Winter
You can reduce watering over the winter. Dipladenias only need watering when the top 2 inches (5cm) of soil begin to dry. Rio Dipladenias come pre-fertilized but plants that have been over-wintered can be fertilized once in May and once in August, with slow-release 18-6-12 fertilizer. Do not fertilize during winter as dipladenias’ natural rest period lasts from October to April.
