Water
The Dipladenia, commonly known as Mandevilla splendens, should be watered regularly during its growing season, which is from spring through summer. Its soil should be kept moist but not waterlogged, meaning you may need to water it once every week or two, depending on the climate and the plant's exposure to heat. Always allow the top inch of soil to dry out between watering sessions. When watering, use roughly 16 to 24 ounces of water for a pot with a diameter of about 10 inches, ensuring even distribution across the soil. Decrease watering in the fall and winter when the plant is dormant.
Light
Dipladenias thrive in bright, indirect light and should be placed in a location where they receive dappled sunlight or partial shade. Direct, harsh sunlight can damage the leaves, so a spot that gets morning light with afternoon shade or filtered sunlight through a curtain is ideal. They can also grow under bright artificial light if natural light is not sufficient.
Temperature
Dipladenias prefer warm temperatures and should be kept in an environment where the temperature ranges from 60 to 70 degrees Fahrenheit. They can withstand temperatures as low as 50 degrees Fahrenheit at night but should not be subjected to temperatures below that as they are not frost-tolerant. The ideal temperature range to promote flowering and healthy growth is between 65 and 80 degrees Fahrenheit.
Pruning
Pruning Dipladenias encourages bushier growth and more blooms. Prune the plant in late winter or early spring before new growth begins, removing any dead or damaged stems and shaping the plant as desired. Pruning can be done again after the main flowering period to maintain shape and size. Always use clean, sharp pruning shears for a clean cut.
Cleaning
As needed
Soil
The Rocktrumpet thrives in a well-draining, fertile potting mix with added perlite or sand for aeration. A peat-based mix works well. The ideal soil pH is slightly acidic to neutral, ranging from 6.0 to 7.5.
Repotting
Rocktrumpets should be repotted every two to three years or when they outgrow their current pot. Spring is the best time to repot to minimize stress on the plant.
Humidity & Misting
Rocktrumpets prefer moderate to high humidity levels, around 50-70%. Avoid placing in very dry environments.
Suitable locations
Indoor
Grow Rocktrumpet near bright windows; avoid direct strong sun.
Outdoor
Plant Rocktrumpet in partial sun, shelter from harsh rays.
Hardiness zone
10-11 USDA
Life cycle
Mandevilla splendens, commonly known as Rocktrumpet, begins its life as a seed, which germinates in warm, moist soil conditions. Upon sprouting, the seedling develops a root system and foliage leaves, prioritizing the establishment of a good root base and foliage for photosynthesis. As it matures into a vegetative state, the Rocktrumpet grows vigorously, climbing structures or supporting itself with twining stems. During the flowering stage, which often occurs in the warmer months, the plant produces large, trumpet-shaped flowers ranging from white to pink and red, attracting pollinators. After pollination, it sets fruit, which contains seeds, completing the reproductive cycle. The plant can then enter a period of dormancy in cooler climates or continue growing in tropical conditions, where it is often evergreen.
Propogation
Propogation time
Spring-Summer
Propogation: The most popular method of propagation for Mandevilla, often known as Rocktrumpet, is through stem cuttings. This is typically done in spring or early summer when the plant is actively growing. To propagate Mandevilla by cuttings, a gardener should select a healthy, non-flowering stem and cut a 4 to 6 inch (10 to 15 centimeters) section just below a leaf node. Itβs advised to remove the lower leaves and dip the cut end in a rooting hormone for better results. The cutting should then be planted in a pot with well-draining soil, watered thoroughly, and covered with plastic to maintain humidity. It's important to keep the soil moist, not soggy, and to place the pot in a warm place with indirect light. Roots will typically form within a few weeks, after which the new Mandevilla plant can gradually acclimate to less humid conditions.
