Propagating Mandevilla Splendens
- Look for a stem on the Mandevilla Splendens plant that is healthy, disease-free, and about 4-6 inches long.
- Using a clean, sharp pair of pruning shears, make a clean cut on the stem about ¼ inch below a leaf node. Make sure to use a sterile tool to prevent any potential diseases.
- Remove all but the top two or three leaves from the cutting. This will help the cutting focus its energy on growing roots instead of supporting leaves.
- Dip the cut end of the stem into rooting hormone powder, tapping off any excess powder.
- Fill a small pot with a well-draining potting mix and make a small hole in the center. Gently place the stem cutting in the hole, being careful not to disturb the rooting hormone powder. Press the soil around the stem to help it stay upright.
- Water the cutting thoroughly, making sure the soil is moist but not waterlogged.
- Place the pot in a warm, bright, and humid spot with indirect sunlight. Mist the cutting regularly to keep it humid, but avoid overwatering it.
- Roots will start to form in a few weeks, and once the roots are established, the Mandevilla Splendens cutting can be transplanted into a larger pot or directly into the garden.
Mandevilla Splendens Growing Requirements
Sunlight
Mandevilla Splendens prefers bright, indirect sunlight. It can tolerate some direct sunlight in the morning or late afternoon, but too much direct sunlight can damage the leaves.
If grown indoors, it should be placed near a bright, sunny window. When grown outdoors, it should be planted in a spot that receives partial shade to protect it from intense sunlight.
Soil
It prefers well-draining soil that is rich in organic matter. A soil mix of peat moss, perlite, and vermiculite is ideal for this plant. It also prefers a slightly acidic soil pH between 5.5 and 6.5.
Water
This plant requires moderate watering that ensures the soil is consistently moist but not waterlogged, and it should be allowed to dry out slightly between watering.
Overwatering can cause root rot and other diseases, while underwatering can cause the leaves to wilt and drop off.
Temperature and Humidity
Mandevilla Splendens prefers warm temperatures between 70-90°F (21-32°C) during the day and 60-70°F (15-21°C) at night.
It can tolerate slightly cooler temperatures during the winter months but should be protected from frost and freezing temperatures. Mandevilla Splendens prefers moderate to high humidity levels. If grown indoors, it should be placed in a room with a humidifier or misted regularly to maintain humidity levels.

Pests
This plant can be susceptible to a variety of pests, including spider mites, whiteflies, mealybugs, and scale insects.

Diseases
Mandevilla Splendens can be susceptible to fungal diseases such as powdery mildew, leaf spot, and stem rot.
To prevent these diseases, make sure to provide adequate air circulation around the plant, avoid overwatering, and remove any diseased leaves or stems promptly. Fungicidal sprays can also be used to control fungal infections.
Mandevilla Splendens Toxicity
It is mildly toxic to humans and pets if ingested, as Mandevilla Splendens contains a toxic substance called iridoid glycosides, which can cause vomiting, diarrhea, and other gastrointestinal problems if ingested.
