Aglaonema 'Tricolor' is a stunning variety of Chinese evergreen, known for its gorgeous multicolored foliage. The leaves boast a combination of green, pink, and cream hues, giving the plant its 'tricolor' name. This plant adds a vibrant splash of color and is ideal for indoor settings due to its low-light tolerance.

Here is a comprehensive guide to care for an Aglaonema 'Tricolor':

1. Light: Aglaonema 'Tricolor' tolerates a range of light conditions, making it a great indoor plant. It can survive in low light but would thrive in medium to bright, indirect light. Direct sunlight should be avoided as it can scorch the leaves.

2. Water: Water the Aglaonema 'Tricolor' when the top 1-2 inches of soil are dry to the touch. Overwatering can lead to root rot. When watering, make sure to water thoroughly and allow any excess water to drain away.

3. Humidity: This plant enjoys a higher level of humidity due to its tropical origin but can also tolerate normal indoor humidity. You can increase humidity by misting the plant, placing it on a tray of pebbles with water, or using a humidifier.

4. Temperature: Aglaonema 'Tricolor' prefers temperatures between 60-80°F (15-27°C). Protect the plant from cold drafts, as it is not cold-hardy.

5. Soil: A well-draining potting mix is important for Aglaonema 'Tricolor'. A general indoor potting mix should work fine. You can also make your own mix using equal parts peat, perlite, and potting soil.

6. Fertilizer: Feed your Aglaonema 'Tricolor' every month during the growing season (spring through summer) with a balanced, water-soluble houseplant fertilizer. Reduce feeding to every other month in the fall and winter.

7. Pruning: Pruning can help to maintain the size and shape of your Aglaonema 'Tricolor'. You can also remove any yellow or brown leaves to keep the plant looking its best.

8. Pests and Disease Control: Watch out for common houseplant pests like spider mites, mealybugs, and aphids. If you notice any, use an insecticidal soap or a neem oil solution to treat the plant.

Remember that each plant is unique and may not conform exactly to general care guidelines. Always observe your plant and adjust care as necessary. Happy growing!
