Care Tips for Aglaonema ‘Siam Aurora’

To keep your Aglaonema ‘Siam Aurora’ thriving, it’s important to provide the right conditions and care. Here are some essential tips to ensure its well-being:

1. Light Requirements

Aglaonema ‘Siam Aurora’ thrives in medium to high indirect sunlight. It is important to avoid direct sunlight as it can scorch the leaves. Place the plant near a window with filtered light or in a well-lit room. If your home doesn’t receive much natural light, you can also use fluorescent lights to provide sufficient illumination.

2. Soil

Ensure that you use well-draining soil for planting your Aglaonema ‘Siam Aurora’. A high-quality potting mix formulated for indoor plants is ideal. It should be enriched with organic matter and have good drainage properties to prevent waterlogged conditions.

3. Watering

Water your Aglaonema ‘Siam Aurora’ when the top inch of soil feels dry to the touch. It is important not to overwater the plant, as this can lead to root rot. Water thoroughly, allowing excess water to drain from the bottom of the pot. Avoid letting the plant sit in standing water, as this can also cause root issues.

4. Humidity

Aglaonema ‘Siam Aurora’ prefers high humidity levels. You can increase humidity by misting the leaves regularly or placing the plant on a tray with pebbles and water. This will create a humid microclimate around the plant and promote healthy growth. However, it can also tolerate average indoor humidity levels, making it suitable for various environments.

5. Temperature

Maintain a temperature range of 65°F to 76°F (18°C to 24°C) for optimum growth. Avoid exposing the plant to cold drafts or extreme temperature fluctuations. Aglaonema ‘Siam Aurora’ is considered a tropical plant and thrives in warm and consistent temperatures.

6. Growth Rate and Size

Aglaonema ‘Siam Aurora’ has a medium growth rate and can reach a maximum height and width of 3 ft (0.91 meters). Regular pruning and maintenance can help control the size and shape of the plant, making it suitable for smaller indoor spaces.

7. Fertilization

During the growing season, fertilize your Aglaonema ‘Siam Aurora’ with a balanced liquid fertilizer. Follow the instructions on the fertilizer packaging to determine the proper application rate. It is important not to over-fertilize, as this can lead to nutrient toxicity and damage the roots. A slow-release fertilizer can also be used according to the package recommendations.

8. Pruning

Pruning is important for maintaining the health and appearance of your Aglaonema ‘Siam Aurora’. Remove yellow or damaged leaves to encourage new growth and prevent the spread of diseases. You can also perform tip-pruning to promote bushier growth and maintain a compact shape.

9. Propagation

Aglaonema ‘Siam Aurora’ can be propagated through division or stem cuttings. To propagate through division, carefully separate the root ball into smaller sections, ensuring that each section has roots and stems. Plant each division in a separate container using well-draining soil. Stem cuttings can be taken and rooted in water or directly planted in moist soil. Provide appropriate care and conditions for the new plants to establish and thrive.

10. Common Issues

Aglaonema ‘Siam Aurora’ is generally a low-maintenance plant, but it can still face some common issues. Keep an eye out for pests such as mealybugs, spider mites, aphids, and scale insects. If detected, treat the infestation promptly using appropriate methods or organic insecticides. Additionally, be cautious about overwatering, as it can lead to root rot and other fungal diseases. Ensure proper drainage and avoid allowing the plant to stand in water.

11. Pet Safety

It is important to note that Aglaonema ‘Siam Aurora’ is considered toxic to pets. Keep the plant out of their reach to prevent any accidental ingestion, as it can cause discomfort and digestive issues.
