The Monstera Thai Constellation is a stunning variegated variety of the popular Monstera deliciosa, known for its beautiful cream-colored splashes across its lush green leaves. Caring for this plant requires a bit more attention compared to other Monstera varieties, but the rewards are well worth it. Here’s a complete guide to keeping your Monstera Thai Constellation thriving.
Monstera Thai Constellation thrives in bright, indirect light. Due to its variegated leaves, it requires more light than the typical Monstera deliciosa to maintain its unique pattern. However, avoid direct sunlight, as it can scorch the delicate white and cream portions of the leaves. A location close to a window facing east or north is perfect, as it allows the plant to get ample diffused light.
This plant prefers consistently moist soil but doesn’t like to sit in water. Water your Monstera Thai Constellation once the upper 1-2 inches of the soil appears dry. If watering into a pot without drainage holes be sure to discard any excess water in the outer pot to prevent root rot.
Throughout the growing period (spring and summer), it might be necessary to water more often. In the winter, when growth slows down, reduce watering. Always use well-draining soil and a pot with drainage holes to prevent root rot.
Monstera Thai Constellation loves high humidity, as it mimics its natural tropical habitat. Aim to keep the humidity levels around 60-80%. You can increase humidity by placing a humidifier nearby, grouping plants together, or placing your Monstera on a pebble tray with water. Regular misting can also help, but avoid letting water sit on the leaves to prevent fungal issues.
This plant thrives in temperatures between 65°F to 80°F (18°C to 27°C). It doesn’t tolerate cold drafts or sudden temperature changes, so keep it away from windows or doors during winter months. If the temperature drops below 60°F (16°C), growth may slow down, and the plant may become stressed.
Use a well-draining potting mix that retains moisture but doesn’t stay soggy. A combination of peat, perlite, and orchid bark is effective. You can fertilize your Monstera Thai Constellation every 4-6 weeks during the growing season with a balanced, water-soluble fertilizer. Decrease the amount of fertilization in the autumn and winter seasons when the plant's development slows down.
Pruning helps maintain the shape and size of your Monstera Thai Constellation. Use clean, sharp scissors to trim any yellow or damaged leaves. You can also prune to encourage bushier growth or remove any leggy stems. If your plant is growing too large, it’s easy to propagate new plants by taking cuttings with at least one node and placing them in water or moist soil until they root.
As a climbing plant, Monstera Thai Constellation will benefit from some support as it grows. A moss pole or trellis allows it to climb naturally, mimicking its growth habit in the wild. The aerial roots will latch onto the support, encouraging larger and more mature leaves.
Like other houseplants, Monstera Thai Constellation can be prone to pests such as spider mites, mealybugs, and scale. Regularly inspect your plant for signs of pests, like tiny webs, sticky residue, or discolored spots on the leaves. Should you notice any pests, immediately address them using insecticidal soap or neem oil. Good air circulation & avoiding overwatering can help prevent fungal issues.
Replant your Monstera Thai Constellation every one - two years, or when you observe that it has become root-bound. Choose a container that is 1-2 inches wider in diameter than the current one. The ideal time to repot your plant is during the spring, when the plant is in its active growth phase.
To propagate a Monstera Thai Constellation, start by selecting a healthy parent plant with at least one node and aerial root on the stem you plan to cut. Use a clean, sharp knife or pruning shears to make a cut just below the node, as this is the point where roots will develop. Allow the cutting to callous for a day or two to reduce the risk of rot. Once the cutting is ready, place it in water, ensuring the node is submerged but the leaves remain above the surface. Keep the container in a bright, indirect light location, and change the water weekly to maintain freshness. Roots should begin to develop within a few weeks. Once the roots are 2–4 inches long, transfer the cutting to well-draining soil, such as a mix of peat, perlite, and orchid bark, to provide the necessary aeration and moisture balance. Keep the soil slightly moist and place the plant in a warm, humid environment with indirect sunlight to encourage healthy growth.
Monstera Thai Constellation grows slower than its non-variegated counterparts due to the reduced chlorophyll in its leaves. Patience is key; new growth might take time, but each new leaf will be a beautiful work of art.
- Yes, it’s a climbing plant by nature, and providing a moss pole or trellis encourages it to grow upright and develop larger leaves. A moss pole also mimics its natural habitat and helps with aerial root attachment.
- Ensure it’s getting bright, indirect light, optimal watering, and high humidity. You can also repot into slightly larger pots as needed and use a balanced fertilizer regularly during the growing season.
- Smaller leaves may result from lack of light or nutrients. Increase the amount of indirect light it receives and ensure proper feeding during its growing season. Larger leaves with more fenestrations (splits) develop when the plant is older and in good conditions with high humidity.
- While it prefers to climb vertically, you can train it to grow horizontally by pinning the stems to a trellis or horizontal support, though this may limit the size of the leaves.
- The white parts of variegated leaves contain less chlorophyll, making them more susceptible to sunburn or dry air. Brown edges can also be a sign of inconsistent watering or low humidity. Keep the plant away from direct sunlight and increase humidity.
- Aerial roots are natural for Monsteras, and you can either tuck them back into the soil or attach them to a moss pole. If they’re too long, you can trim them without harming the plant
- Use the soak and dry method: water the plant thoroughly until water drains from the bottom, then allow the top few inches of soil to dry out before watering again. Make sure the pot has excellent drainage, and use a chunky, well-aerated soil mix.
- This is often due to insufficient light. Move the plant to a brighter spot, ensuring it gets enough indirect sunlight. Leggy growth may also result from lack of pruning or insufficient nutrients.
- Like other Monsteras, the Thai Constellation is toxic to pets (cats and dogs) if ingested. It contains calcium oxalate crystals, which can cause irritation in the mouth and digestive issues. Keep it out of reach of pets.
- Variegation is genetically determined, but strong, consistent lighting can help the plant maintain its striking patterns. However, avoid overexposing it to direct sunlight as the white parts are more prone to burning.
- Wilting can occur due to overwatering or underwatering, root rot, or transplant shock if recently repotted. Check the soil moisture and root health. Ensure you aren’t using too large of a pot, as it may retain excess moisture.
- Yes, it can be grown in hydroponic setups or in water for an extended period, but it may need liquid fertilizers for nutrients. However, it’s important to monitor water levels and change the water regularly to prevent root rot.
- While rare in Monstera Thai Constellation, some leaves may lose variegation due to low light. Ensure the plant is in a well-lit area to preserve the variegation. Variegation might also decrease as the plant ages, but this is not typical for this species.
- It can survive in low-light conditions but will grow slower, and the variegation may not be as vibrant. Ideally, provide it with bright, indirect light to maintain healthy growth and patterns.
