Monstera Thai Constellation

Monstera Thai Constellation

The Thai Constellation Monstera has become one of the most highly sought-after plants in recent years. Due to the rare mutation which is responsible for the stunning pattern and colors, they are difficult to mass produce using the same means of cultivation used for most plants.  

  • Light

Bright light is incredibly important with the Thai Constellation. Not only will insufficient light cause poor growth, but in rare cases, the Thai will 'revert', causing the mutation to go dormant and it will start putting out leaves which look like an ordinary Monstera.

Bright, indirect light is best. While low-light conditions will result in the aforementioned issues, excessive direct-light can cause leaf scorching, especially apparent in the variegated leaves. If you do not have the ideal light conditions in your home, using a high quality grow light like Soltech will be the best way to provide your Thai with optimal light conditions.  

  • Water 
Similar to the light needs for your Thai Constellation, watering must be just right. A concern for most Philodendron, Thai's are susceptible to root rot and it's crucial that it has the opportunity to dry out in between waterings. Assuming proper, bright-indirect lighting, a weekly watering over the spring and summer months will be suitable, with less frequent watering over the winter months. Your growing medium will greatly impact the watering needs so be mindful that a coco coir / perlite mix will dry out faster than a peat-based potting mix. 

  • Humidity

Given the delicate nature of Thai leaves, ambient humidity will be crucial to facilitate healthy new growth, as well as the plant's ability to maintain the integrity of existing leaves. 

50% relative humidity is the absolute minimum required, however it will be happiest at levels closer to 60%. A humidifier is an absolute must to achieve these levels of humidity outside of the naturally humid summer months. 

  • Soil
While a high-quality potting mix such as Fox Farm Ocean Forest will work nicely, many growers will choose to create a mix of coco coir and perlite to manage the nutrient uptake entirely through watering. While a high-quality potting mix comes rich in nutrients like worm casings or bat guano, coco/perlite mixes do not contain any medium-based nutrients and as such, will require their nutrients by mixing appropriate supplements into each watering. 

  • Fertilizer 

If growing in a coco/perlite medium, fertilizer is administered in every watering. If, however, you are growing in an all-purpose soil, fertilizing every other watering during the spring and summer months will be best to keep your Thai happy and healthy. 



  • Pet friendly? 
No, the Thai Constellation, like all Philodendron, are toxic to pets if consumed.
