About Mandevilla
A tropical twining vine producing large, showy trumpet flowers (8-10 cm) in vivid pink, red, or white against glossy dark green leaves. Blooms prolifically in warm weather and adds dramatic vertical color to trellises, arbors, and container supports. Mandevilla belongs to the Apocynaceae family and originates from Brazil; cultivated throughout tropical and warm temperate regions..
Mandevilla is gaining popularity in Philippine gardens as an alternative to the more common alamanda. Its large, elegant flowers and manageable vine habit make it perfect for trellis gardening on small urban lots. Performs best in the Philippine dry season (March-May) when flowering is most prolific. Available at premium nurseries in Antipolo, Silang, and Tagaytay.
Also known as: Brazilian Jasmine, Dipladenia, Rock Trumpet.

Care Guide
Sunlight
Full sun to partial shade (needs at least 6 hours of sun for good flowering). Position your mandevilla where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Regular watering — keep soil moist but not waterlogged. Reduce in cooler months. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity
Ideal temperature range: 22-35°C (thrives in Philippine warmth; cold-sensitive below 15°C). Moderate to high — naturally suited to Philippine conditions The warm, humid Philippine climate is well-suited for growing mandevilla outdoors or indoors.
Fertilizer
High-phosphorus fertilizer every 2 weeks during blooming season.
Pruning
Prune in early growing season to control size and encourage branching. Provide a trellis or support.
Toxicity & Safety
Milky sap is mildly toxic and can irritate skin. All parts are toxic if ingested. Keep away from pets and children.
Common Problems & Solutions
Few or no flowers
Cause: Insufficient sunlight or too much nitrogen fertilizer
Solution: Move to sunnier location. Switch to high-phosphorus (bloom-boosting) fertilizer.
Yellow leaves
Cause: Overwatering, poor drainage, or nutrient deficiency
Solution: Check drainage. Let soil dry slightly between waterings. Feed with balanced fertilizer.
Aphids on new growth
Cause: Soft new shoots attract aphids
Solution: Blast with water. Apply neem oil or insecticidal soap.
Vine not climbing
Cause: Needs a support structure — mandevilla twines around supports
Solution: Provide a trellis, obelisk, or strings to climb. Guide young stems onto the support.
