- Fertilization: Feed the plant with a balanced fertilizer every two weeks during the growing season, from spring to fall.
- Soil: Plant mandevilla in well-draining soil that is rich in organic matter. A pH level of 5.5 to 6.5 is ideal.
- Sunlight: Mandevilla plants require full sun to flower. Provide at least six hours of direct sunlight per day.

Common Pests & Diseases
Mandevilla plants are susceptible to several pests and diseases, including:
- Spider mites: These pests can cause yellowing and stippling of the leaves. Use an insecticidal soap to control them.
- Mealybugs: These pests appear as white, cottony masses on the plant. Use an insecticidal soap to control them.
- Powdery mildew: This fungal disease causes a white, powdery coating on the leaves. Improve air circulation and avoid overhead watering to prevent it.
- Root rot: Overwatering can cause root rot, which can lead to wilting and death of the plant. Allow the soil to dry out between waterings.
