Care Guide for Aglaonema pictum tricolor
Light Requirements
 
Needs bright, indirect light for 8–10 hours daily to maintain strong variegation.
Avoid direct sun, which can burn and fade leaves.
Watering
 
Allow the top 50–70% of the soil to dry before watering.
Use soft or filtered water to prevent mineral buildup on leaves and roots.
Humidity and Temperature
 
Thrives in 70–85% humidity. Use a terrarium, humidifier, or plant cabinet for best results.
Ideal temperature: 18–24°C. Never expose to temperatures below 15°C.
Soil and Potting
 
Best grown in a loose, airy aroid mix with orchid bark, perlite, and coconut coir.
Repot every 2–3 years, preferably in a breathable pot with excellent drainage.
Fertilization
 
Feed monthly during the growing season with a balanced, diluted liquid fertilizer.
Semi-Hydroponics
 
Adapts well to semi-hydro setups with LECA or pon if high humidity and careful nutrient management are provided.
Pruning
 
Remove yellow or damaged leaves to redirect energy to healthy growth.
Encourage branching by pruning top shoots carefully.
Common Issues and Troubleshooting
Browning Tips or Edges
 
Low humidity or hard tap water are frequent causes. Increase humidity and use filtered water.
Yellow Leaves
 
Usually signals overwatering or poor drainage. Adjust watering frequency and soil quality.
Pest Problems
 
Watch for thrips, spider mites, and root mealybugs. Treat early with neem oil or insecticidal soap.
Fungal Infections
 
Caused by stale air and excess moisture. Improve airflow and reduce watering if needed.
Special Growing Tips for Success
 
Keep it in a stable, warm environment — this species dislikes fluctuations.
Consider terrarium cultivation for maximum color intensity and steady growth.
Rotate regularly for symmetrical leaf development.
