Philodendron Monstera Thai Constellation (also known as Monstera Thai or just Monstera Thai Constellation) is relatively easy if you provide the right conditions. Here's a guide to help you keep your plant healthy: 

Lighting

• Bright, Indirect Light: Monstera Thai Constellation thrives in bright, indirect light. Avoid direct sunlight as it can scorch the leaves and damage the plant.
• Low to Moderate Light: It can tolerate lower light conditions but will grow more slowly and may not develop its signature variegation.

 Watering

• Moderate Watering: Water your plant when the top 1-2 inches of soil feel dry to the touch. The Monstera prefers to dry out a bit between waterings.
• Drainage: Ensure that the pot has good drainage. Overwatering or letting the plant sit in water can cause root rot.
• Humidity: This plant loves humidity, so if your home is dry, mist the leaves occasionally or use a humidifier to maintain moisture in the air.

 Soil

• Well-Draining, Aerated Soil: Use a potting mix that is light and well-draining. A peat-based mix with perlite or orchid bark added works well to keep the soil airy.
