Mandevilla Red Care Guide for Alans Garden

Botanical Name: Mandevilla spp.
Common Name: Red Mandevilla
Plant Type: Tropical flowering climber

Light

• Thrives in bright sunlight with at least 6 hours of direct sun daily.
• In very hot climates, provide light afternoon shade to prevent leaf scorch.
• Insufficient light results in fewer flowers and leggy growth.

Watering

• Water thoroughly when the top 2–3 cm of soil feels dry.
• Keep the soil slightly moist but never waterlogged.
• Reduce watering during cooler months.
• Overwatering can cause yellow leaves and root rot.

Soil

• Use a well-draining, fertile potting mix rich in organic matter.
• A mix containing potting soil, compost, and coarse sand or perlite works well.
• Ensure pots have good drainage holes.

Temperature & Humidity

• Prefers warm temperatures between 21–32°C.
• Protect from temperatures below 10°C.
• Enjoys moderate to high humidity but adapts well to typical outdoor conditions in tropical regions.

Fertilizing

• Feed every 2–3 weeks during the growing and flowering season.
• Use a balanced liquid fertilizer or a bloom-boosting fertilizer for abundant flowers.
• Reduce feeding during winter.

Support & Training

• Mandevilla is a vigorous climber and performs best with a trellis, arch, or support structure.
• Regular training helps create a fuller, more attractive display.

Pruning

• Trim long vines after flowering to maintain shape.
• Remove dead, damaged, or weak growth regularly.
• Light pruning encourages branching and more blooms.

Common Problems

• Yellow leaves: Usually caused by overwatering or poor drainage.
• Poor flowering: Often due to insufficient sunlight or lack of fertilizer.
• Pests: Watch for aphids, mealybugs, whiteflies, and spider mites. Treat early with neem oil or insecticidal soap
