Care for Monstera deliciosa 'Thai Constellation'

Keeping 'Thai Constellation' in perfect condition is easier than with many other rare aroids, but its amazing panoramic leaves with creamy variegation require a specific approach to maintain their beauty.

💧 Watering

• When to water: Water only when the substrate is approximately 1/2 to 2/3 dry. Unlike common monsteras, 'Thai' is more susceptible to root rot (due to its laboratory origin in tissue cultures).
• Warning signs: If the leaves noticeably droop their long petioles, it's high time to water. Conversely, brown, "soggy" spots on the creamy parts indicate overwatering.
• Water quality: Use room temperature, settled or rainwater. Too cold tap water can cause shock and browning of the light variegated areas.

☀️ Light

• Ideal conditions: Requires bright indirect light (filtered). Sufficient light is crucial for maintaining a contrasting creamy color and promoting the formation of fenestrations (holes in the leaves).
• Lack of light: The plant will grow very slowly, stems will be "leggy" and stretched, and leaves may remain small and without holes.
• Beware of sunburn: Direct midday sun can irreversibly burn the sensitive chlorophyll-free (creamy) parts of the leaves. Ideal placement is near an east-facing window or further away from a south-facing one.

🌡️ Temperature and air

• Temperature: Standard room temperature of 18–27 °C is ideal. It does not tolerate drafts and temperatures below 15 °C.
• Air humidity: The goal is 60% and above. If the humidity in the apartment drops below 40%, the tips and edges of the leaves will start to brown and dry out.
• Humidity tips: It thrives best near a humidifier or on a saucer with moist LECA. Misting the leaves is not recommended for this monstera, as standing water on the leaves can promote mold growth in variegated areas.

🌿 Fertilization

• Season: Fertilize once every 14–21 days from spring to autumn.
• Concentration: Use a quality fertilizer for aroids or ornamental plants, but at half concentration. This monstera grows slower, and excess salts in the substrate could damage its more sensitive root system.

🧽 Substrate

• Composition: Requires a so-called "Aroid mix". It must be extremely airy and well-draining so that the roots can breathe.
• Recommended recipe: A mixture of quality substrate, pine bark, perlite, coco coir chips, and a little charcoal (acts as a rot preventative).
