What is a Monstera Thai Constellation?

Monstera Thai Constellation is a stunning, rare variety of the Monstera species. Similar to appearance as the Monstera Deliciosa, the thai constellation differentiates itself through its beautifully variegated foliage. 
As the Thai Constellation matures, it produces wide, fenestrated green leaves with splashes of cream throughout the foliage. These creamy specks are due to the lack of chlorophyll in the leaves which gives plant foliage its green color.

NEVER buy Monstera Thai Constellation seeds!
Be wary of anyone trying to sell monstera thai constellation seeds! It’s impossible to grow variegated varieties from seedlings (but you can grow regular monstera deliciosa from seed!).
Similar to Monstera deliciosa, Monstera Thai constellation has a more upright growth habit and can be trained up moss poles as they mature. They make great options to fill large spaces or corners in a living room or an office. 
Despite the lack of chlorophyll, Monstera Thai constellations can be a fairly forgiving rare plant variety. Most rare plants come with difficult care needs, but as long as you provide proper bright light and warm temperatures, you’ll be able to make this rare Monstera thrive.
In this guide, we’ll cover how you can purchase and care for your Monstera Thai Constellation as well as how to propagate through stem cuttings.

If you’re looking to snag a variegated Monstera, you’ve probably come across both Monstera Thai Constellation and Monstera Albo Variegata. They are both rare varieties producing variegated leaves with a green base and creamy to bright white colors intermixed. 
The main difference between the two is the aesthetics of the variegation. Monstera Thai constellation has a more creamy white variegation with speckles throughout the leaves (just like a star constellation!). The Monstera albo features more blocky, bright white variegation on its leaves producing a much more dramatic difference. Both have generally similar care needs and need more light than your fully green Monsteras.

Purchasing Monstera Thai Constellation Online (and affordably)

Mature Monstera Thai Constellation plants can go for thousands of dollars. These plants, because they don’t occur naturally, are extremely rare and have high demand. Although growers like Costa Farms have tried to make Thai Constellations more accessible by mass producing them, they are still hard to find online on the cheap.
If you’d like to get your hands on this rare plant, but don’t have thousands to shell out, we recommend purchasing nodes or wet sticks online. You can often purchase a stem with a node online for 100-200 or less. You’ll want to make sure you find a reputable retailer online and inspect the variegation on the photos of the node. The more variegation on the stem and node, the more likely your Monstera Thai Constellation will have variegation as it matures.

How to Care For Monstera Thai Constellation

Once you’ve gotten your hands on this rare plant, proper care and maintenance is critical. Because this is a variegated variety, it’ll need proper light and soil to thrive well. Just like other tropical plants, Monstera Thai Constellation prefers high humidity and warm temperatures.
It’s best to place this beauty near a source of bright indirect light for 4-6+ hours and make sure you keep its soil moderately moist. You’ll want to allow the soil to dry out a few inches in between waterings.

As long as you follow a proper watering schedule and provide your Thai Constellation plant enough light, you’ll have a thriving, lush vine in no time.
In this guide, we’ll cover plant care for your Monstera Thai Constellation from proper watering needs to light requirements, and lastly how you can properly propagate your tropical plant.

💧 Water

Being tropical plants, your Thai Constellation prefers moderately moist soil. You will want to allow the top few inches of soil to dry in between waterings. Don’t let the soil get consistently soggy, otherwise, this will lead to fungal diseases like root rot which can kill your (very expensive!) plant. 
Keep in mind your local weather and climate as that will play a part in your watering schedule. If you live in a dry, arid region, you’ll want to water your Monstera more frequently to upkeep its growth.
We recommend you plant your Thai constellation in a pot with a drainage hole to allow any excess water to drain. If you’re planting your constellation monstera in a pot without a drainage hole, you’ll want to measure out the exact amount of water you are using. We recommend about half the size of your pot.

We don’t generally recommend misting unless you are located in an arid region where misting is a must to mimic natural jungle climates.
How often should I water my Thai Constellation Monstera?
As a general rule of thumb, we recommend you water roughly 1-2x a week during its active growing season in Spring and Summer. During its dormant months in fall and winter, slow down to once every 7-10 days. Like most tropical aroids, you’ll want to keep its soil moderately moist only allowing top few inches to dry in between waterings. Never let your soil become soggy for a long period of time which can lead to root rot. 
What are signs of an overwatered Thai Constellation Monstera?
If you’re starting to see yellow leaves, it may be a sign of overwatering especially if you’ve noticed that your soil has been consistently soggy.
How do I know I need to water my Monstera Thai Constellation?
If you’re starting to see brown or crispy leaves and your plant is wilting, this is a sign that your Monstera Thai Constellation isn’t receiving enough water or its getting too much direct sunlight. Adjust your watering schedule accordingly.
Should I mist my Monstera Thai Constellation?
If you live in an arid region, we recommend misting to mimic a tropical environment. However, you can safely grow you Thai Constellation without regular misting. Moisture buildup can cause issues like fungal diseases if not managed carefully.

☀️ Sunlight

Unlike green varieties of Monstera Deliciosa which can tolerate moderate to low light conditions, your Monstera Thai Constellation needs more bright light to thrive. This variegated variety lacks chlorophyll and needs more light to make the same amount of energy and nutrition as its solid-colored sisters. 
We recommend you place your Thai Constellation Monstera in a space that receives 8-12 hours of bright, indirect sunlight. A few feet away from a South-facing window to avoid direct sunlight will work well. You can also place it near an east or west-facing window, but we recommend supplementing it with additional light.

If you don’t have access to proper natural light, really consider investing in a proper grow light
If you’re starting to see your leaves turn crispy, this could be a sign of overexposure to direct sunlight. Move your Monstera Thai Constellation away from a direct light source into a partially shaded area to help recovery.

🌡️ Temperature and Humidity

Monstera Thai Constellation is a tropical plant used to growing in warm temperatures and humid environments. Most room temperatures will work and the most ideal ranges are between 60 and 85 degrees Fahrenheit. Don’t let temperatures drop below 50 degrees Fahrenheit and move your plant indoors during cooler months if you’re growing outdoors on a patio space.
Avoid placing your Monstera Thai Constellation near air conditioners or exterior doors and windows or heaters to avoid cool and hot air drafts. This can burn the plant creating crispy, brown leaves. 
If your space is dry, we recommend you invest in a small humidifier or group your houseplants together to encourage proper humidity levels. You can also place a pebble tray filled with water near your plant.

🌱 Best Soil for Monstera Thai Constellation

Monstera Thai Constellation is an aroid that required well-draining, organically rich soil. If you’re able to get your hands on a specialty aroid mix, we recommend you do so. 
Commercial houseplant potting mix will work as well, but we recommend supplementing with sphagnum moss or coco coir for moisture retention and perlite for extra drainage support.
 Avoid potting mixes with any water-retentive gels to avoid water build up which can lead to root rot.
It’s critical to have proper drainage for your Monstera to prevent fungal diseases like root rot. Always make sure to plant your aroids in containers with drainage holes.

🌻 Fertilizer

Monstera Thai Constellation is a slow grower but can do well with some regular fertilizing. We recommend you supplement it once a month with a regular, liquid houseplant fertilizer (10-10-10, 20-20-20) during its growing season in the Spring and Summer.
We recommend holding off on any fertilization if you recently repotted your plant. Allow for 6 months for the plant to settle in before feeding it.

☢️ Toxicity

Like other monstera plants, Monstera Thai Constellation is toxic to pets (dogs and cats). We recommend you keep your furry friends away from this plant!

How to Propagate Monstera Thai Constellation From Stem Cuttings

The easiest way to propagate your Monstera Thai Constellation is through stem cuttings. As long as you have access to either water, soil, peat moss, or LECA, you can have a new Monstera Thai Constellation in no time.
Proper propagation will ensure that you’re able to have a healthy new Monstera Thai Constellation in no time. Being a variegated variety, it’s a bit more difficult to propagate and you can’t guarantee that your plant will have the level of variegation as it matures.

Stem Cuttings Propagation Step By Step:

  • Prepare a new container, gloves, sterilized shears and, sphagnum peat moss, or leca depending on your medium of choice.We don’t recommend using soil because there’s a higher susceptibility to build up of moisture leading to root rot of your cuttings! Key drainage and aeration is important. We recommend using peat moss paired with perlite or leca.
  • Take your mother or parent plant and find a stem that has at least 1-3 nodes (where leaves attach to the stem and aerial roots will appear). It’s critical to find a stem with a node, otherwise roots will not form.
  • Use your sterilized shears to cut off a section of the stem including those nodes
  • Place your new cutting with node down into the growing medium. 
  • Make sure to cover your container to generate a mini-greenhouse and create humidity. Use a plastic wrap or bag and cut a slit or two in the bag to add aeration. 
  • Place in a warm, sunny spot. Make sure to keep consistently moist.
  • It’ll take 4-8 weeks  for your stem cuttings to root. Once you start to see new growth and new leaf emerge, you can transplant your new plant into a new container.

How to Repot Monstera Thai Constellation

Monstera Thai Constellation is a very slow growing plant, so you’ll likely need to repot it every 2-3 years. You’ll know you need to repot your Thai Constellation plant if you start to see roots coming out of the drainage hole of your pot.
To repot your Thai Constellation:
  • Prepare gloves, a container 2” larger in size to allow room for root growth, well-draining soil mix
  • Gently remove your Thai Constellation from its container and ruffle away remaining soil
  • Inspect the roots for signs of root rot. If you see mushy or brown roots use sterilized shears to cut them away
  • Prepare your new container and fill with soil ⅓ of the way through.
  • Place your plant into the new container and backfill with soil
  • Water thoroughly and follow proper care instructions.

Common Monstera Thai Constellation Pests & Diseases

You probably spent a pretty penny on your Monstera thai constellation, so you’ll want to really take care of it carefully and trouble shoot issues. Like other aroids, this variegated plant is susceptible to common issues like root rot and pests like thrips.

Root Rot

If this is your first time experiencing root rot, read our full guide on root rot.
Root rot is a common issue with most houseplants including Monstera Thai Constellation. It’s usually caused by moist or waterlogged soil for prolonged periods of time. Symptoms can include rapidly yellowing leaves, stunted growth, and a rotten brown base. If you’re seeing these symptoms, here’s how to treat root rot.
  • Remove the plant from the pot and gently remove the soil so you can see the root system.
  • If the roots are brown and mushy, you must take action immediately.
  • Clean off the roots with sterile water.
  • Take sterilized scissors and trim any mushy roots.
  • You can use a diluted hydrogen peroxide solution to disinfect the roots.
  • Once cleaned up, repot your plant in fresh houseplant soil mix.
Like other aroid plants, Monstera Thai constellation can be susceptible to common houseplant pests like spider mites, fungus gnats, and thrips.
Read about how to treat spider mites (orange pests), and fungus gnats (flying, annoying pests).

Thrips

These pesky, tiny pests can infiltrate your Monstera if there’s improper light or water care. These small insects suck out the sap of the leaves taking away its nutrition.
They reproduce rapidly laying larvae once they infest a plant. We recommend isolating and treating your plant immediately once you spot an infestation.
Thrips are tiny brown, white insects that can be found on top or undersides of leaves. They are hard to spot, but if you see tiny specs on your leaves, it’s likely a sign of a thrip infestation.
Why is my Monstera thai constellation turning yellow?
There can be several reasons why your Monstera thai constellation is developing yellow leaves. If you’re seeing older leaves turn yellow, it may be a sign of a nutrient deficiency. When was the last time your repotted or fertilized your plant? It may be a sign that you need to refresh your soil and give your monstera a boost of plant food. If on the other hand, you’re seeing more foliage turn yellow and notice that the soil has been consistently moist, it may be a sign of overwatering. Pause watering and let the soil dry out, and resume on a slower schedule than usual.
Why is my Monstera thai constellation turning brown?
If your Monstera leaves are turning brown, it may be a sign of lack of water and moisture. Are you growing in a dry environment and forgetting to water often? Increase your watering frequency. At times, this can also be a sign that your plant is experiencing root rot. If you feel like you *have* been watering enough, but haven’t been allowing your soil to dry, we recommend checking your plant’s root system to ensure there’s no signs of root rot.
Why is my Monstera thai constellation not growing?
If you’re seeing dramatic decrease in your Thai constellation’s growth, it may be a sign of root rot or your monstera’s roots being root bound. Either way, we recommend you repot your plant and inspect the roots in the process. Outside of that, slower growth can be a result of improper light in particular. Make sure that your Thai constellation is receiving 8-10 hours of light every day.
