Monstera Constellation (a.k.a. ‘Thai Constellation’) is one of the most eye-catching houseplants you can grow, but it also comes with special care needs. From its slow growth to its sensitive variegation, there are many things to know before bringing one home. This plant is not just about looks; it requires time, attention, and the proper setup to stay healthy. Knowing what to expect helps you avoid mistakes and gives your plant the best chance to thrive. If you consider adding this rare beauty to your collection, here are the key things to remember.
1. Expect a Higher Price Tag
Monstera Constellation is not cheap. Because it is rare and slow to grow, prices tend to be high. Even small cuttings can cost more than mature common Monsteras. If you find one for a low price, make sure it is healthy and labeled correctly. Buyers should be ready to invest not just money, but also time and effort. This plant is often seen as a collector's item.
2. It Grows Slowly Compared to Other Monsteras
Do not expect quick growth from this plant. Unlike regular Monstera deliciosa, the Constellation takes its time. It may take several months to see new leaves, especially in lower light or dry air. This slow pace means every leaf is more valuable, but it can also test your patience. Tracking progress with photos can help you appreciate the subtle changes.
3. It Needs Bright, Indirect Light—No Direct Sun
Bright, indirect light is best for this plant. Direct sun can burn its leaves, especially the white parts. If you place it near a sunny window, use a sheer curtain to protect it. Without enough light, the plant may lose variegation or stop growing. Finding the right light balance is key to healthy, happy leaves. Rotate the plant every so often to help it grow evenly.
4. Variegation Can Be Unstable
Not every new leaf will look the same. Some may have lots of white, while others have very little. This is normal with variegated plants. The amount of white can change due to light, nutrients, or just plant genetics. Sometimes, a plant may even revert and lose its variegation over time. While you cannot fully control it, proper care helps encourage better coloring.
5. Humidity Plays a Big Role in Its Health
This plant prefers a humid environment. If the air is too dry, its leaves may get crispy edges or brown spots. Aim for humidity above 50 percent, especially in winter when heaters dry out the air. A humidifier or pebble tray can help boost moisture around the plant. Grouping it with other plants can also raise local humidity. Consistent levels help the plant thrive.
6. Use a Chunky, Well-Draining Potting Mix
Monstera Constellation needs soil that drains fast and has lots of air pockets. A mix of orchid bark, perlite, and potting soil works well. This keeps the roots from sitting in soggy soil, which can cause rot. Avoid dense or compact mixes that hold too much water. Repotting every couple of years helps refresh the mix and encourage new growth.
7. Don’t Let the Roots Sit in Water
Overwatering is a common mistake with this plant. Its roots do not like to be wet for too long. Let the top few inches of soil dry out before watering again. Make sure the pot has drainage holes. Sitting in water can lead to root rot, which is hard to fix once it starts. Always check the soil moisture with your finger before adding more water.
8. Fertilize Lightly but Regularly During Growing Season
This plant benefits from regular feeding, but only in small doses. Use a balanced, water-soluble fertilizer every 4 to 6 weeks during spring and summer. Too much fertilizer can damage the roots or cause leaf burn. In fall and winter, reduce feeding or stop altogether. Healthy plants with enough nutrients tend to show better growth and coloring.
9. Propagation is Possible but Tricky
You can propagate this plant, but it is not always easy. Cuttings need at least one node and a good chunk of stem. Because of its slow growth and high value, many owners are careful with pruning. Rooting in water or moss can work, but it takes time and close monitoring. Be patient and expect a slow process. Not all cuttings will survive.
10. Watch for Pests Like Spider Mites and Thrips
This plant can attract pests, especially if kept indoors. Spider mites, thrips, and mealybugs are common issues. Check under leaves and along stems often. Signs of trouble include spots, webbing, or deformed leaves. A quick response with insecticidal soap or neem oil can help stop pests before they spread. Keeping the plant clean also helps prevent problems.
11. Leaf Fenestration Doesn’t Always Happen Early
Fenestration is when the leaves get holes or splits, but this takes time. Young plants may grow full, solid leaves for many months. Light, age, and plant health all affect when fenestration appears. If your plant has solid leaves, be patient. Over time, with good care, the splits will come. Do not cut healthy leaves just because they look plain.
12. Rotate the Plant for Balanced Growth
This plant tends to lean toward the light. To keep it growing straight and full, rotate the pot every week or two. This helps each side get enough light. Without rotating, one side may become long and leggy while the other stays short. Even light exposure keeps the plant balanced and attractive from all angles.
13. Be Patient—It Takes Time to Thrive

This is not a fast-growing or low-maintenance plant. It rewards long-term care and patience. You may not see big changes for weeks or even months. Stick to a routine and give it time to adjust. With steady care, it will develop into a stunning, mature plant. Do not rush the process.
14. It’s Sensitive to Temperature Swings

Sudden changes in temperature can stress this plant. Cold drafts, hot air from vents, or quick drops in room temperature can lead to damage. Try to keep it in a room with steady temps between 65 and 80 degrees Fahrenheit. Avoid placing it near windows or doors that open often in winter. Stable conditions help it grow strong and steady.
15. Not Ideal for Beginners Without Aroids Experience
This plant is best for people who already care for aroids. It needs more attention than basic houseplants. If you have grown Monsteras, Philodendrons, or Anthuriums before, you will be better prepared. Without that background, it might feel tricky to manage. Learning with easier plants first helps build the skills needed for success.
16. Leaf Damage Is More Noticeable on Variegated Plants
Because the leaves have white or cream patches, any damage stands out more. Brown tips, pest marks, or tears are very easy to see. Gentle handling, good humidity, and regular checks help keep the leaves clean and bright. Treating the plant with care helps preserve its beauty.
17. It May Require Support as It Matures
As this plant grows larger, it may need help staying upright. A moss pole or plant stake gives the stems something to climb. This support helps the plant grow stronger and more stable. It also encourages bigger, more dramatic leaves. Without support, it may lean or tip over.
18. Shipping Can Be Risky for This Variety
This plant does not always travel well. Long trips or poor packaging can damage its delicate leaves. It also takes time to bounce back after shipping. If you order one online, check for reviews and seller policies. When it arrives, let it adjust before repotting or moving it around too much.
19. Rarely Found at Big-Box Garden Centers
You are unlikely to find this plant at your local big-box store. It is more common at specialty nurseries or from private sellers. Sometimes, you may need to join a waitlist or watch for restocks. Be prepared to shop around or check online plant communities. Getting one may take time, but it adds something rare to your collection.
What to Keep in Mind Moving Forward
Adding a Monstera Constellation to your space is a big step, but it can also be rewarding. This plant offers a stunning look, but only if you are ready to meet its care needs. From humidity and light to pests and patience, each detail plays a part in helping it grow well. It is not the easiest plant to manage, but with steady care, it becomes a true standout. If you love learning as you grow, this plant will be a good match for your collection.
