1. Light & Temperature

Monstera Thai Constellation might survive under low light but cannot thrive well.  

Generally, Monstera Thai Constellation needs adequate 6 to 8 hours of indirect bright sunlight at a temperature between 65°F to 70°F.  The plant growth will slow down under low light and temperatures below 64º F.

Leggy growth, a lack of split and holes with the loss of leaf variegation can result from insufficient light. And eventually, the plant stops growing below 50º F as Mosteras are prone to frost injuries.

That said, though Monstera loves warm temperatures, you should not leave your plant under 90 degrees Fahrenheit.

It will cause plants to dry up and wilt. Besides, the scorching sun can make the plant turn yellow and suffer from sunburn. 

Tips to Maintain Ideal Light & Temperature

  • Place the plant near the south or west-facing windows under bright indirect sunlight.
  • Use a curtain to reduce the light intensity by 30% to 50%, which is safe for Mostera plants.
  • You can also apply a grow light with the red-blue light spectrum instead of white. 
  • Also, you must remove the plants from the chill window during winter. 
  • You can also grow the plant in a greenhouse. Make sure you have enough heating capacity to grow the plant in winter.

2. Water & Humidity 

Though Monstera is a tropical plant, avoid watering it frequently.

Generally, Monstera Thai Constellation will need water once a week in summer and every 10 to 12 days in winter, with over 6-% % humidity.

Meanwhile, excess soil and air moisture may lead to bacterial root rot, brown spots on leaves, mould growing on soil, oedema on the leaves, and wilting and curling.

Likewise, if you forget to water the plant, spots appear on the leaves, and the plant droops.

Monstera Thai Constellation needs a tropical environment.

So, to maintain optimum moisture, bottom water the plant using rainwater or filtered water for Monstera and group it along with other house plants.

 You can fill a tray with 1-inch pebbles and water halfway up the pebbles or place the plants in the bathroom or kitchen. 

Avoid unfiltered or dirty water as it may cause the browning of tips and edges.

Further, you can use a humidifier to increase the humidity around your plant, or your plant may wilt and leaves turn crips and yellow with brown edges.

3. Soil & Fertilizer

Monstera is adaptive to a wide range of soil as long as it is well-draining with sufficient nutrients. 

Although not a heavy feeder, you need to feed the plant with a balanced fertilizer during its active growing season, ensuring the soil pH doesn’t exceed 5.0 to 7.5.

You can make DIY potting soil by mixing 1 part peat moss/coco coir, 1 part perlite, and 4 parts pine bark fines. Also, add some organic manure to support better growth. 

Keep in mind that excessive feed can cause more harm to the plant than good. The chemical burn in the soil can cause root rot and leaf discoloration. 

So, before randomly applying the fertilizers, have a look at the table for soil and fertilizer option suitable for Monsteras.

Tips for fertilizing Monstera

  • Do not apply liquid fertilizer directly to dry soil. Only fertilize your Monstera after watering it and leaving it the whole night. 
  • Dilute the liquid fertilizer to 1/4 of the recommended strength and pour it directly onto your plant’s soil.
  • Ensure the fertilizer does not directly touch flowers, fruits, leaves, or stems to avoid fertilizer burn.

Expert Tip! Combine potting soil with perlite and a few chunky pieces of bark or sphagnum moss to retain the excess moisture.

4. Potting & Repotting

Monstera Thai Constellation also needs repotting once every two years with 2 inches bigger pots in diameter unless they show the root bound sign.

General root bound sign includes roots peeking out of the drain hole, soggy soil, droopy leaves, and stunted growth. Repot the plant immediately as you notice these signs.

Terracotta would be the best choice for the plant’s root, but concrete and plastic can also do the job. But the pot should be about 2 feet wide (60 cm) to support a stake or moss pole for the Monstera to climb.

  1. Choose a good pot according to the size of your plant. Prepare the required soil mix and get a moss pole.
  2. Cautiously remove the Monstera from its pot with gentle hands. Cut off aerial roots if they are extremely long or infected and turn the pot over and gently coax the roots. 
  3. Check if the roots are too packed for this and dig a narrow, deep hole into inserting the pole if it has a similar condition.
  4. If you are repotting the Monstera with its old moss pole, hold the plant over the pot, firmly stake the pole into the pot, and narrow the roots down.
  5. Use rain or filtered water for watering. For once, water the plant until the water comes out of the drainage holes.

Pro Tip: Your plant may still appear droopy after repotting. Do not worry, as it shall start growing once it adjusts to the new home.

5. Regular Pruning

Monstera generally does not require much pruning, making it a low-maintenance plant.

Prune the plant annually, in spring or summer, and the plant is good to live for a long period.

However, you should consider pruning if you see dead and dried-up foliage attacked by pests and diseases. Monstera usually falls prey to bugs such as thrips, scale, mealy bugs, and spider mites. 

Fungal diseases, including Powdery Mildew, Anthracnose, and Monstera Leaf Blight, also disturb plant growth.

First, try neem oil or dish soap to control the pests and disease spread. If the invasion does not subside, pruning becomes mandatory.

  • Start by cutting diseased or dead plant parts first.
  • Throw the cuttings away when you’re done. If not, Monstera can easily root in the ground.
  • Do not prune too much or more than 1/3 of the plant to make the plant younger.

Monstera Thai Constellation: All About Growth Rate

Monstera Thai Constellation is a slow-growing climber that reaches maturity in about two years.

Normally, Monstera can grow from 10 to 15 feet tall outdoors and stretch 8 feet wide. Upon ambient growth environment, it can grow up to 2 feet tall annually.

But indoor Mostera Thai Constellation can only grow up to 8 feet long (2.5M). 

Regardless of the location, support the plant by using a moss pole or wooden or bamboo to stake the Monstera plant.

Foliage Profile

The plant has a signature shape of the paint strokes of Jackson Pollock on the leaves.

The leaves showcase a beautiful pattern of cream splotches against green to dark green leathery leaves.  Further, the mature foliage usually is 18 inches or more.

Flower and Fruit

Monstera Thai Constellation produces a large white flower that rarely blooms throughout spring and summer. 

Flowers are off-white in color, lightly scented, and non-showy, and the size of each flower is about 6 to 12 inches.

Monstera Thai Constellation Flower includes spadix and spathe.

Moreover, these blossoms produce a fruit that looks like an ear of a cob covered with green hexagonal scales. It can reach up to 12 inches in length and 2 inches in width.

The fruit is edible and tastes like pineapple and jackfruit, but you should not consume the unripe fruit.

Toxicity of Monstera Thai Constellation 

According to the ASPCA, Monsteras, in general, are toxic (level 3 to 4) to pets and humans, and Thai Constellation is no different.

Monstera contains calcium oxalate crystals that can be toxic to cats and dogs. Pets feel oral irritation and difficulty swallowing with excessive drooling followed by vomiting.

Avoid the pets around the Monstera plants.

You should immediately contact the nearby vet or the animal poison helpline.

Propagation Methods for Monstera Thai Constellation

Monstera Thai Constellation has multiple ways to populate itself into an entire mini jungle. 

Gardeners prefer propagating Moustera, including the mini Monstera, by stem cutting, air layering, or plant division.

Seeds can produce the plant, but variegated leaves will not come from the seeds.

They will still require parts of the stems of leaves to produce the same variegated coloring.

1. Propagation via Stem Cuttings 

To continue propagating a Monstera Thai Constellation, you must identify stem cuttings with at least one leaf and a visible aerial root.

Cuttings need to be ½ an inch to an inch below the node. You can also propagate  Monstera without a node.

  • Select a mature, healthy stem node and cut right below a node with sterilized pruning shears.
  • Remove all leaves except one or two.
  • Dip the cut end in root growth hormone to stimulate plant growth.
  • Fill the pot with potting mix, then plant the cutting with the node in the soil and lightly water them.
  • Cover the cutting with a sealable plastic bag to preserve humidity. You can also poke a hole or two to facilitate respiration.
  • Keep the pot under indirect bright sunlight and remove the bag after a week, and your plant will start rooting after 3 to 5 weeks.
  • After the root grows over 3 inches, you can transfer the plant to another pot.

The steps in growing the plant in water are similar to soil propagation, but you dip your node in water. Do not cover the plant with a plastic bag, and make sure you change the water every few days.

You can transfer the plant to the soil after 4 to 6 weeks.

2. Propagation via Air Layering

This process does not require cutting nodes and propagating in any medium. For this, you will need peat moss. 

  • Take a healthy stem and make a small cut at the node with sterilized shears or a knife.
  • Take some moss in your hand and wrap the cut with the moist peat moss, and seal it with a plastic bag. 
  • Make some holes in the bag to allow air circulation
  • Mist the area regularly; after a few weeks, you can withdraw the plastic.
  • When there is an outgrowth of roots, you can cut the new stem and plant it in a new pot.

3. Propagating via Plant Separation

Monstera Thai grows in dense, so separating the plant helps in keeping your plant a manageable size and apart from giving the free plants. 

  • Add water to the Monstera plant and let the soil dry.
  • Gently transfer the Monstera plant from the planter into an open space.
  • Grab a pair of scissors and cut the pot through the soil, and gently divide the roots into two or more new plants.
  • Make sure you perform it without cutting any stems and leaves.
  • Now take a new pot a few inches bigger than the root balls of each new plant.
  • After that, you can plant the stem cuttings into a pot with rich soil.
  • Now, place the young plants under the bright spot.
  • And water the plants regularly according to the soil condition.

FAQs about Monstera Thai Constellation

Does a Thai Constellation require a moss pole?

We recommend Moss poles, but they are not strictly required.

Moss pole does provide support to this climbing plant and may provide nutrients and moisture as well.

Why is Monstera Thai Constellation too expensive?

Monstera Thai is expensive because it is rare and highly popular with demand.

This species grows more slowly than any other standard Monstera Deliciosa and is more difficult to propagate. Thus, suppliers can run out of stock extremely fast.
