Recommended Potting Mix

potting mix

Monstera deliciosa ‘Thai Constellation’ should be planted in a nutrient-rich, well-draining potting mix. Remember to maintain a 70/30 ratio in mind. With that being said, use around 30% potting mix and 70% free-draining soil. It’s essential to keep the soil moist but not soggy or mushy!

A high-quality indoor potting mix with bark and perlite will assist greatly improve drainage. Remember that these plants are prone to root rot, so dense, heavy soil is a big no-no! To promote healthy growth, roots must be free of excess moisture.

Watering Needs

The Monstera ‘Thai Constellation’ has a very sensitive root system. So, when watering your Monstera, make sure to water well and adequately drain the water after. Allow the soil to never dry out or become soaked with water. Neither is good for the plant’s health. During the spring and summer, you should water your Thai Constellation about once a week and less in the winter.

Pro tip: The moisture level in your plant’s soil is a considerably better guide to knowing your plant’s watering demands. Moisture levels can be measured with a soil pH tester kit or by inserting your finger 2 inches below the soil’s surface.

Ideal Lighting

The more white variegation there is, the harder it is for a plant to photosynthesize. And that’s the reality for this Monstera Thai. Because light is so essential for photosynthesis, your Thai will require more light than the all-green Monstera. So, choose a location with a lot of bright indirect light. Enough lightning must be filtered or dispersed through transparent curtains or windows with some texture on the glass.

The leaves of your Thai Constellation should be kept out of direct sunlight to avoid harm. This can be remedied by moving your plant to a location that better meets its light requirements.

Requirements for Temperature & Humidity

Thai Constellation thrives in temperatures between 68 and 86 degrees Fahrenheit (20 and 30 degrees Celsius). Because Thai Constellations are not frost-hardy, keeping them outside of this temperature range for an extended length of time can harm them. If you reside in a colder region, keep it indoors as much as possible.

Keeping your Thai Constellation happy and healthy requires a medium to the high humidity level. They are accustomed to high humidity levels due to their upbringing in a laboratory and restricted environment, especially as young plants. So you can mist your Thai Constellation once or twice a week, but don’t overwater it. Fungus gnats can be attracted to a persistently damp soil surface. You can also use a humidifier or even a pebble tray to assist in creating such proper humidity.

Need for Fertilizer

The Thai Constellation is a slow-grower than all-green Monstera deliciosa. So, that means they are also light feeders. But that doesn’t mean you should starve them. Don’t forget to feed your Thai, but don’t overdo it. You don’t want to expose the Monstera Thai to fertilizer burn.

liquid fertilizer

During the growing season (Spring/Summer), your Thai Constellation should be fed moderately with an indoor plant fertilizer every 4-6 weeks. Indoor plant fertilizers in liquid form are a convenient way to give your plant the nutrition it requires. Follow the instructions carefully so that you are well-guided.

Fertilizing is not necessary during the colder months because this can cause health problems. Overfertilization during this season causes burned leaves, wilting, and stunted development.

Propagation Methods

Now, we are here in the most exciting part: propagation! Stem cuttings are the most excellent way to propagate your Monstera Thai Constellation. The procedure is nearly identical to that of reproducing a typical Monstera deliciosa plant. Here’s you will propagate this Monstera:

  • During the growth season, cut a plant stem from your healthy, mature Thai Constellation. At least one node and leaf should be present in the stem cutting.
  • You don’t want to use anything too heavy medium because the Thai Constellation is prone to decay. Use a combination of good soil, sphagnum moss, and perlite instead.
  • Make sure the stem isn’t buried too deeply in the soil. However, make sure the node is completely covered. Maintain a humid, warm, and light atmosphere for the plant.
  • The rest is up to you: frequent watering, appropriate light and humidity conditions, and patience coupled with optimism that it will grow into a beautiful new Monstera thai!

Growth Zone

The Monstera Thai Constellation is ideally grown in USDA growth zones 9b through 11.


You may grow your Variegated Monstera in large, deep pots with plenty of support. They may become leggy vines if not supported. Ensure that the pots have drainage holes at the bottom. Given that Thai Constellation grows more slowly than its full-coloured siblings, there is no need to regularly move the plant from one pot to another.


To maintain your plant looking healthy and promote new development, just trim back any unruly, broken, or discoloured leaves. Because it is a sluggish grower, a Thai Constellation plant should only be pruned once a year, in the spring or autumn.

Pro tip: Always cut slightly above a node or as close to the main stem as possible with a sterile and sharp knife or set of scissors.

Monstera Thai Constellation Plant Diseases & Pests


Whitefly, Mealybugs, and Scale can infest Monstera deliciosa ‘Thai Constellation’ plants regularly. This is owing to the humid climate in which they must exist. These pests are unsightly and bothersome, but they are unlikely to harm your plant in the long run if you act early when you notice them.

To treat an infestation in its early stages, carefully dab away all visible evidence of these pests with a moist cotton tip, cotton pad, or clean towel. Check under the leaves and between the leaf and stem nodes for any bugs that may be hiding.

After that, wash as much of the remaining infestation away using neem oil, soapy water, or, if you prefer, a watered-down household insect spray or detergent. Re-do this treatment until these bugs are out of sight.


When it comes to diseases, the first major problem is most frequently associated with root rot. This terrible occurrence’s main indications and expressions are yellow, droopy, wilting, and eventually falling off leaves. It could be caused by overwatering, in which the root does not obtain adequate oxygen due to being submerged for too long. So the first thing to keep in mind is that you don’t overwater your Monstera thai.
