4" Thai Constellation

Monstera ‘Thai Constellation’ – Care Guide

Overview

Monstera ‘Thai Constellation’ is a variegated cultivar of Monstera deliciosa, featuring creamy-white marbled splashes and speckles across its large, fenestrated leaves. Named for its constellation-like speckling, this cultivar was tissue-cultured in Thailand and is more stable than many other variegated Monsteras (like Albo Variegata), making it a bit easier to care for — though still rare and pricey!

Key Characteristics

Botanical Name: Monstera deliciosa ‘Thai Constellation’
Common Name: Thai Constellation Monstera
Plant Type: Tropical evergreen aroid
Growth Habit: Climbing/vining, with aerial roots
Mature Size (indoors): 4–8 feet tall and wide
Leaf Size: Up to 18–24 inches across with mature fenestrations and splits
Foliage: Deep green with stable creamy-white marbling, speckles, and sectors

Light Requirements

Bright, indirect light is ideal to maintain variegation
Tolerates some filtered sunlight, but avoid harsh direct sun, especially on the white parts which are more prone to scorching
Low light will reduce variegation and slow growth

Watering Needs

Water when the top 2 inches of soil are dry
Likes consistent moisture but hates soggy roots
Ensure excellent drainage and never let it sit in water
In winter, water less frequently as growth slows

Soil & Potting

Needs a well-aerated, chunky, fast-draining soil mix

• Ideal mix: potting soil + orchid bark + perlite + a bit of coco coir or peat
  

Use a pot with drainage holes
Repot every 1–2 years or when root-bound

Temperature & Humidity

Temperature: 18–27°C (65–80°F); avoid temps below 15°C (59°F)
Humidity: Prefers 60–80% humidity

• • Mist lightly or use a humidifier in dry environments

  • Benefits from being grouped with other plants

Fertilizing

Feed every 4 weeks during spring/summer with a balanced liquid fertilizer
Reduce or skip feeding in fall/winter
White parts of leaves don’t photosynthesize — overfeeding can lead to leaf burn or stress

Support & Growth

Provide a moss pole or trellis to mimic its natural climbing habit
Encourages larger, fenestrated leaves with maturity
Slow to moderate grower indoors — faster with warmth, light, and humidity

Common Problems

Root rot: from overwatering or compact soil
Crispy leaf edges: often due to low humidity or inconsistent watering
Pests: Watch for spider mites, thrips, mealybugs, and scale

• • Treat early with neem oil, insecticidal soap, or horticultural oil
    

Yellowing leaves: Often caused by overwatering or too little light

Toxicity

Toxic to pets and humans if ingested (contains calcium oxalate crystals)
Keep away from cats, dogs, and children

Special Notes

More stable variegation than Monstera albo — less likely to revert
Slower growth than regular Monstera deliciosa
Large, white areas are more delicate and prone to damage — treat with care
Considered a "collector's plant", often priced higher than standard Monsteras
