Maintaining the beauty of your Allamanda plant is relatively straightforward. Here’s a quick guide:

1. Light: Provide full sunlight for at least 6 hours a day. Allamandas thrive in bright, sunny conditions.
2. Soil: Use well-draining soil rich in organic matter. A slightly acidic to neutral pH is ideal.
3. Watering: Keep the soil consistently moist, especially during the growing season. Allow the top inch of soil to dry out before watering again. Reduce watering in winter.
4. Temperature: Allamandas prefer warm temperatures above 60°F (15°C). Protect them from cold drafts and frost.
5. Fertilization: Feed with a balanced, slow-release fertilizer during the growing season (spring and summer). Reduce or stop fertilizing in fall and winter.
6. Pruning: Trim to shape the plant and remove spent flowers. Prune after the flowering season to control size and encourage branching.
7. Support: Provide support for climbing varieties. Allamanda vines can be trained on trellises or arbors.
8. Pest Control: Watch for aphids, scale insects, and spider mites. Treat infestations promptly with insecticidal soap or neem oil.
9. Caution: Handle with care due to the toxic sap. Wear gloves when pruning or handling the plant.

By attending to these aspects, you’ll foster a thriving and visually appealing Allamanda, showcasing its vibrant trumpet-shaped flowers in your garden or landscape.
