1. Indirect Bright Light
The light has a huge role in Monstera Thai Constellation as the cream-colored parts of their leaves cannot photosynthesize.
Monstera Thai Constellation needs adequate 6 to 8 hours of indirect bright sunlight.
However, do not keep your Monstera Thai under direct sunlight as the plant usually does not tolerate it.
As Monstera Thai can not absorb enough light, they need to work hard for preparing their food so low light is not recommendable.
The entire plant’s body survives on sunlight utilized by chlorophyll in those leaves. Hence, the plant requires a higher intensity of filtered sunlight.
Dangers of Improper Lighting Condition
Monstera Thai Constellation might survive under low light, but it will not be thriving. The plant develops the following symptoms.
- The plant shows leggy growth as it stretches its stems to reach a brighter area.
- As Monstera Thai is a climber, it has aerial roots. Low light conditions result in poor development of aerial roots.
- Monstera Thai Constellation is popular for its big green-creamy patches of leaves but not enough light results in small, green leaves.
- Low light conditions result in a lack of split and holes in the loss of leaf variegation.
The scorching sun can make your monster suffer from sunburn and the following will be symptoms if goes unanswered!
- Too much bright sunlight can cause overheating of the plant pot. Hence, it results in the drying of soil and the plant. Keep in mind that Monstera Thai thrives in moist soil.
- Bright sunlight for hours results in low humidity. Monstera Thai Constellation requires higher humidity.
- With bright sunlight ultimately resulting in dryness and low humidity, your Monstera will lose that beautiful foliage, and all the leaves will gradually turn yellow.
- Likewise, the leaves lose all their chlorophyll, and photosynthesis terminates. Thus, the plant gradually dies.
Tips to Maintain Ideal Light Condition for Monstera Thai Constellation
- Keep your Monstera near the west or south-facing window for 6 to 8 hours.
- You can also apply a grow light with the red-blue light spectrum instead of white. However, if you are growing other plants together, consider getting a white grow light bulb.
- You can also keep your Monstera outdoors under a shade cloth to ensure it does not get bright sunlight.
- Place the plant near the south or west-facing windows under bright indirect sunlight.
- Also, if there is a window crowed with unfiltered light, you can cover the plant with a curtain.
- Misting with a cup of water can be another way to neutralize the effect of the excess light.
2. Moderate Watering
As Monstera Thai are tropical plants, meaning that they enjoy quite a lot of water but an overflood of water can let your monster develop wet feet.
It would be best if you only rewatered your Thai Constellation when the top 2 inches (about five cms) of the soil is dry. If the soil looks moist, leave it be.
Monstera Thai Constellation will need water once a week in summers and once every 10 to 12 days in winters.
This ensures that your Monstera is not too dry or soggy.
Effect of Improper Watering in Monstera Thai Constellation
Overwatering of Monstera poses several dangers to the plant, including decaying of its roots and stems. Too much moisture makes the plant roots soggy, creating a favorable environment for bacteria.
The most common signs and symptoms of an overwatered Monstera include bacterial root rot, brown spots of leaves, molds growing on soil, Edema on the leaves, and wilting.
When you start noticing the pot getting wet and perspiration in the leaves, back off watering.
Underwatering Monstera causes drying out of the plant.
Hence, the plant loses its beautiful variegation in leaves. Likewise, spots appear on the leaves, and the plant starts to droop.
The solution to prevent underwatering is simply checking moisture levels and water accordingly.
Tips for Watering Monstera Thai Constellation
- Most professional gardeners and plant lovers recommend rainwater or filtered water for Monstera. Unfiltered or dirty water can cause the browning of tips and edges.
- Properly aerate the soil before watering the plant.
- It is also wise to use a moisture tracker to know exactly when to water your plant. Products like Soil Moisture Meter and Water Checker are pretty helpful.
Expert Tip! Combine potting soil with perlite and a few chunky pieces of bark or sphagnum moss to retain the excess moisture.
- Likewise, I would recommend nitrogen-rich fish tank water. Mix some clean fish tank water with double the amount of filtered water.
3. Warm Temperature
Monstera Thai Constellation grows in tropical climates.
Thus, the optimum growth temperature for Monstera Thai Constellation needs ranging from 64°F to 70°F (18 to 21 degrees Celsius)
The Monstera Thai is not frost-hardy, meaning it can not survive in freezing temperatures. However, it can tolerate temperatures lower or higher than optimal growth temperatures short term.
Any temperature lower than 18 degrees celsius will slow down the plant’s growth, while temperatures lower than 10 degrees will eventually stop its growth.
Likewise, higher temperatures also have adverse effects on photosynthesis.
Symptoms of Unfavorable Temperature in Monstera Thai Constellation
When your plant is too cold, root and stem rot might occur. Frost adds excess moisture so the plant pot might be too soggy and wet, causing rotting.
Besides, very low temperatures can also cause yellow patches on the leaves.
Though Monstera loves warm temperatures, you should not leave your plant under 90 degrees Fahrenheit. It will cause plants to dry up, and wilting to occur.
Also, leaves can curl and roll up in high temperatures.
Tips to Maintain Ideal Temperature for Monstera Thai Constellation
- By installing HVAC (Heating, Ventilation, and Air Conditioning) system, you can easily control air temperature and humidity.
- Make sure you use the right size HVAC, depending on the area of your room.
- You can also grow the plant in a greenhouse. Make sure you have enough heating capacity to grow the plant in winters.
- Likewise, make sure there is a proper cooling system.
- Install Horizontal Air Flow (HAF) fans to make sure the area is properly ventilated and cooled. However, do not place the fan too close to the plant to make sure that the plant retains moisture.
- You can also use shade curtains to block excess light and heat from the sun. Shade curtains reduce 30% to 50% light.
- You can also use temperature control sensors to make sure the temperature is optimum for plant growth.
- Use gas or electric artificial heaters if the temperature goes down.
- Also, you need to remove the plants from the chill window during winter.
4. High Humidity
As a tropical plant, Monstera Thai Constellation loves a humid environment.
Usually, Monstera Thai Constellation grows well in humidity of over 60%. However, it can tolerate up to 40% humidity.
Low humidity causes the plant to wilt, and the leaves turn crisp and yellow with brown tips. It may also slow down the plant’s growth.
Likewise, too high humidity causes perspiration in leaves. The leaves become excessively damp and start to form closely together.
As Monstera Thai usually start their lives in a lab, in ambient humidity and temperature, it is necessary to maintain that throughout their lives.
Tips to Maintain Ideal Humidity for Monstera Thai Constellation
- Group your plants together: In this way, a humid microclimate can be created by transpiring plants. It is wise to keep Monstera together as they have the same moisture requirements.
- Use a pebble tray: Fill a tray with 1-inch pebbles and fill with water halfway up the pebbles. Then keep the plant pot above the pebbles. This ensures that there is proper moisture.
- Use a humidifier: A humidifier is an extremely convenient option. They are not only good for plants, but also for your skin and allergies.
- Place it in the bathroom or kitchen: Your Monstera Thai will love the ideal ambient humid condition of the bathroom.
- Regularly Misting: Misting is very helpful during winters and the dry seasons with clean water.
- Make a Terrarium: It is a sealed, indoor garden. The plants transpire water droplets and the droplets gather on the walls of the terrarium. Hence, the same transpired droplets fall back into the plant like a real water cycle.
5. Well-draining Soil
A good soil mix provides plants with proper nutrients, proper gas exchange, and optimum temperature, and also acts as an anchor.
Normally, Monstera Thai Constellation grows best in well-aerated or draining soil with a pH of 5.0 to 7.5.
Monstera Thai loves moist soil with high organic matter and nutrients but you need to avoid soggy soil. You can select a peat-based soil mix in cold months for this.
If you have compost excessively dry, the Monstera leaves will start turning brown.
DIY Potting Mix: 1 part peat moss/coco coir, 1 part perlite, and 4 parts pine bark fines.
You can either make your own potting mix or you can get the readymade mix in stores and shops online. Here are a few recommendations.
|Soil Sunrise Potting soil||Hand blended, contains natural,organic components|
|Rooting For You Monstera Potting Mix||Locally Sourced, Pest Free Contains natural ingredients: Pumice, Coco Coir, Coco Husk, Bark Nuggets, BioChar, & Worm Castings|
|Premium Monstera Potting Soil||Natural and Gentle Formula, especially composed for Monstera|
|Miracle-Gro Indoor Potting Mix||Protects against gnats, helps plants grow up to six months|
|Miracle-Gro Potting Mix||Prevents underwatering and overwatering, grows fed plants twice as big as unfed|
6. Monthly Fertilizer
Monstera Thai Constellation is a slow-growing plant so it does not need a heavy food supply.
So, you can spray your moss with a small portion of fertilizer to give your Monstera a boost without shocking it with chemicals directly into its soil.
Like other Monstera plants, Monstera Thai Constellation can grow with the monthly general-purpose fertilizer.
The growing seasons including spring and summer will be best to fertilize the plant so you need not feed your monster in the winter.
Following are the commercial fertilizer recommendations for your Monstera’s needs.
|The Grow Co Organic Monstera Plant Food||Made specially for Monstera's needs, organic an environment friendly|
|Houseplant Resource Center Monstera Plant Food||Perfect NPK ratio, encourages plant growth|
|Fiddle Leaf Plant Fertilizer||Made exclusively for indoor plants. Best NPK ratio for Monstera growth|
|Fast Growing Trees Monstera fertilizer||Easy application, right nutrients specific to Monstera Thai|
|Espoma Organic Indoor Plant Food||Organic, easy application, and fast result|
Besides these, you can also use an organic, all-natural fertilizer or Worm Castings. This compost is the closest Monstera can get to its natural environment.
Use Hack: Simply layer the castings about 1/4 to 1/2 inch on top of the soil and water it. The worms will work on their magic by adequately airing and enriching the soil.
However, you need to avoid overfertilization of your Monstera, and like other gardeners who want the plants to grow quicker.
The most common condition is fertilizer burn after this. The symptoms include white crust on top of the soil, yellowing of leaves, stunted growth, and wilting leaves.
However, you can wash away the excess fertilizer with water.
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.
- Do not fertilize during the winter season.
- Slow-release and granular fertilizers should be kept directly in the soil and then watered.
- Organic Fertilizers are always better than synthetic ones when it comes to Monstera Thai Constellation.
- Also, dilute the liquid fertilizer to 1/4 of the recommended strength and pour it directly onto your plant’s soil.
- Likewise, you can use 1/4 of the recommended amount of granular fertilizer.
- Make sure the fertilizer does not directly touch flowers, fruits, leaves, or stems to avoid fertilizer burn.
7. Extended Repotting
Monstera needs a pot with a proper draining system. Likewise, the pot should be big enough to support a stake or moss pole for the Monstera to climb up.
The pot size depends on the size of the Monstera plant.
If you have a baby Montera, consider getting a pot no more than 8 inches(20 cms). A mature Monstera may require a pot that’s about 2 feet wide (60 cms).
You can plant your Monstera plants in pots of any materials such as ceramic, plastic, concrete, clay, and wood.
When the plant grows adult, it will need a new home.
Thus, Monstera Thai Constellation needs repoting once every two years with 2 inches bigger pots in diameter.
You can know the repotting time considering the following signs.
- When a healthy Monstera grows too small for its original pot
- When the soil has a fungal or bacterial infection
- When the water drains out quickly as you water the plant
- If the plant is rootbound
- If the plant’s growth stops
Do not re-pot your Monstera for a few months after purchasing. Monstera Thai should be well-acquainted with its environment before repotting.
Remember, repotting puts a lot of stress on the plant, thus, you should not do it frequently.
Steps to Repot Monstera Thai Constellation
Step 1: Preparation
Choose a good pot according to the size of your plant. Prepare the required soil mix and get a moss pole.
Step 2: Removal of Plant from the Old Pot
Cautiously remove the Monstera from its pot with gentle hands. Cut off aerial roots if they are extremely lengthy or infected and turn the pot over and gently coax the roots.
Step 3: Potting the Monstera
If you have a moss pole, arrange the plant around the pole. Check if the roots are too packed for this and dig a narrow, deep hole to insert the pole if it has a similar condition.
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.
Step 4: Watering the Monstera
Use rain or filtered water for watering. For once, water the plant until the water comes out of the drainage holes.
Tips to Repot Monstera Thai Constellation
- Choose the best time: Usually, spring is the best time to repot your Monstera as the Monstera will probably hit a growth spurt at this time.
- Use a suitable pot and soil mix: A good pot has a proper drainage system so choose a good soil mix that provides proper aeration, nutrition, and drainage.
- Use sterile shears: Sometimes, cutting a tiny portion of root might be required. Make sure you use sterile scissors or shovels, etc to handle the plant to avoid infection.
- Use filtered water: Tap water might be harmful to plants as they contain chlorine. Bacteria in tap water may also cause infection.
- No fertilizer: Avoid using any fertilizer for at least 4 weeks after the transplant.
8. Occasional Pruning
Monstera does not require much pruning in general, making it a low-maintenance plant. However, you should consider pruning if you see dead and dried-up foliage.
You can prune once every two years, especially in spring or summer for better growth.
Also, pruning of underground roots is necessary if you are transferring your Monstera into a new pot. If you want growth, cut the part you want to grow.
Steps of Pruning Monstera Thai Constellation
- Firstly, choose the plant parts to be cut. This ensures that you have your Monstera in your desired size.
- Put on your gloves as Monstera sap could irritate your skin and could be toxic.
- Take a sterile and sharp pruning tool. A sterile tool prevents infection while if the tool is sharp, you can cut the plant with one snip preventing infections.
- Cut below a node if you are propagating the plant. However, if you are cutting to just reduce the size, do not worry about this.
- Sterilize the shears or clean other pruning essentials to use for the next time.
Things to Consider While Pruning Monstera Thai Constellation
- The sap of Monstera could be toxic and/or irritating. Make sure you wear gloves and do not allow kids or pets to come near the plant.
- Do not go back and forth while pruning. Try to cut the plant tissue with one snip.
- 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. Avoid accidental propagation.
- Do not prune too much or more than 1/3 of the plant to make the plant younger.
Monstera Thai Constellation: Growth Rate
Monstera Thai Constellation is a slow-growing climber that reaches maturity in about two years.
Monstera can grow reach anywhere ranging from 10 to 15 feet tall indoors and stretch 8 feet wide.
It gets an ambient growth environment and can grow up to 2 feet tall per year.
When kept indoors with proper care, the Thai Constellation can grow up to 8 feet in length (2.5M).
The most attractive and desirable part of the Monstera Thai plant is its variegated foliage. The plant has a signature shape of the paint strokes of Jackson Pollock on the leaves.
Monstera Thai Constellation gets its name because the plant was first grown in a lab in Thailand.
The scientists harvested the cells of a variegated Monstera deliciosa and created an even more variegated pattern.
Thus, the leaves showcase a beautiful pattern of cream splotches against green to dark green leathery leaves. The size of the leaves varies, but usually, mature foliage is 18 inches or more.
Flower and Fruit
Monstera Thai Constellation produces a large white flower that rarely blooms if grown indoors. The flowers develop throughout summer and spring.
They are off-white in color, lightly scented, and non-showy, and the size of a flower is about 6 to 12 inches.
Monstera Thai also bears a fruit that looks like an ear of 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
Monstera Thai Constellation is mildly toxic to both humans and pets.
According to ASPCA, Monstera deliciosa contains calcium oxalate crystals that can be toxic to cats and dogs.
The toxicity levels of the Monstera Thai plant reach 3 or 4, which shows slightly toxic and slightly irritating.
Following will be the symptoms developed if the pets consume.
- Oral irritation
- Intense burning and irritation of the mouth, tongue, and lips.
- Excessive drooling
- Difficulty swallowing
In this case, you should contact the animal poison helpline immediately.
Propagation Methods for Monstera Thai Constellation
Monstera Thai Constellation has multiple ways to populate itself to be an entire mini jungle however, it can not be like a plaything or the propagation happens in other plants.
I have explained some methods you can try to perform your best and gift a new Monstera Thai to your dear ones or keep for yourself.
1. Propagation via Stem Cutting
To continue propagating a Monstera Thai Constellation, you need to identify stem cuttings having 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 know about what happens when Propagating Monstera Without Node.
You can propagate Monstera Thai Constellation in two different mediums through stem cuttings.
1. Propagation in Soil Medium
For soil propagation, remember that your soil must not be too wet and soggy. You need a plant pot, pruning shears, potting mix, plant root growth hormone, and a sealable plastic bag.
Follow the following steps to continue the propagation.
- Select a mature, healthy stem with nodes 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.
- Water the cutting and cover it 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.
- 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.
2. Propagation in Water Medium
Water Propagation is favorable if you do not want a mess and want to see your plant’s roots grow.
However, it takes a longer time and the plant might not grow well when transferred into the soil.
The steps 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. Following are the steps to perform air-layering:
- 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 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 into a manageable size and apart from giving the free plants.
Follow the steps to continue the propagation.
- 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.
4. Propagation via Seed
As Monstera Thai is among the slow-growing indoor plants, it takes the plant to take up to 2 years to fully mature. However, variegated leaves will not come from the seeds.
Seeds can produce the plant, but they will still require parts of the stems of leaves to produce the same variegated coloring.
The most preferable method for seed propagation is the Paper towel method. Here is how you can do it.
- Spread the seeds on a paper towel.
- Lightly cover the seeds with another layer of paper towel.
- Spritz with water until the towel and seeds are moist.
- Put it in a bright area, avoiding direct or prolonged sunlight.
- Spritz the seeds daily and you will see growth within 3-6 days.
- The seeds are ready to be transferred and planted in a pot.
Here is a video if you need visual guidance for propagation.
Common Problems in Monstera Thai Constellation
Thai Constellations can have difficulty growing for a number of reasons and a few reasons are underwatering, overwatering, overfeeding, a lack of nutrients, and sunlight.
However, these beautiful Monstera species will turn ugly and leggy if pests and diseases come into contact.
1. Common Pests
Monstera usually falls prey to bugs such as thrips, scale, mealy bugs, and spider mites.
These pests become active in warm environments and cause much damage to plants as they directly attack plant tissues.
|Thrips||Holes in leaves and stems|
|Mealy Bugs||Spotting, discoloration, sticky residue on plant parts, black mold growth over the residue|
|Spider Mites||Discoloration of leaves, small brown or red spots, webbing all over the plant|
|Scale bugs||Yellowing and wilting of leaves, eventual death of the plant|
|Fungal gnats||Wilting of leaves, poor growth of the plant, loss of vigor|
- You can easily remove pests like scale insects with a toothpick or a butter knife.
- Spider Mites can easily be washed away with a stream of water.
- To get rid of mealy bugs, simply dip a cotton ball in alcohol and swab leaves.
- You can also mix liquid dish soap with water and spray on the bugs.
- Or, add 1 part vinegar with 3 parts water and spray!
- Isolate new plants from your existing houseplants for at least 30 days.
- Clean the leaves of your plants as pests thrive in dirty leaves. Thus, you need to clean the plant leaves once every 3 days with a clean, damp cloth.
- Use neem oil. Add 1 tbsp neem oil to 1 liter of lukewarm water and 1 tbsp insecticidal soap. Spray the mixture on the plant surface.
- Remove weeds from the plant pot soil. These weeds are the perfect source of food and shelter for various pests.
If your Monstera is infested despite all your efforts, I can suggest to you some products available for purchase across the internet to get rid of them!
|Products||Effective For||Product Images|
|Neem Oil||Scale bugs, Mealy bugs, Thrips|
|BTI Spray||Fungus Gnats, Black flies|
|Leaf Armor||Spider Mites and some fungi and bacteria|
|Garden Safe Houseplant Insect killer||Fungus Gnats, leaf hoppers, white flies|
|Gro-Sure Houseplant Insect Control Spray||Fungus Gnats, scale bugs, and most other pests|
2. Horticultural Diseases
Bacterial and fungus infections in Thai Constellation are quite common, especially in overwatered plants and in winters.
Some Fungal Diseases include Powdery Mildew, Anthracnose, and Monstera Leaf Blight.
Most of these fungal infections or diseases occur when the environment is favorable for fungus. That is when you overwater your plant and keep it in a damp or cold place.
Look at the table to know how these diseases affect the Monstera Thai Constellation.
|Powdery Mildew||Podosphaera xanthii||Appearance of grayish-white fluff on the leaves|
|Monstera Leaf Blight||Helminthosporium turcicum||Brown spots surrounded by yellow rings in plant parts near soil|

|Bacterial Leaf Spots||Xanthomonas campestris||Appearance of pale halo around a black or brown spot, sap oozing around the spots, black and distorted leaves|
|Root Rot||Erwinia chrysanthemi||Black or Brown leaves, distorted growth|
- Apply neem oil as it is the most popular antimicrobial agent used in the treatment of fungal and bacterial diseases in plants.
- For treatment of bacterial root rot, dip the root in an antibiotic like oxytetracycline before repotting it on fresh soil.
- Wash the infected pots with a bleach-water solution.
- You can also use mancozeb, Anilazine, or copper octanoate for fungal control.
- Also, snip off the infected plant part to treat Powdery Mildew.
- Make sure you irrigate your plant with rain water, treated water, or filtered water.
- Do not overwater your Monstera. Provide the plant with enough sunlight, especially when it is damp.
- Make sure to use only sterile tools while pruning.
- Quarantine any new plants for at least 3 weeks before adding them to your plant collection.
Monstera Thai Constellation Vs. Albo
Monstera Thai Constellation and Monstera albo might look the same. But to the real plant lovers, these two varieties of Monstera have some striking differences.
The main difference between these two Monstera plants is the variegation in leaves. Thai Constellation has evenly scattered creamy yellow variegation, while Albo has a huge white spot covering one half of a leaf.
Let’s look at the different features of Monstera Thai in comparison to Albo.
|Monstera Thai Constellation||Monstera Albo|

|Leaves can easily reach 2 feet or more in length.||Leaves do not grow more than 12 inches long.|
|Short internodes, thus more bushy||Nodes are 6 inches apart, so the plants have an elongated look.|
|Easier to propagate||Harder to propagate|
FAQs about Monstera Thai Constellation
Does a Thai Constellation require a Moss pole?
We recommend Moss pole, 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 it is also more difficult to propagate. Thus, suppliers can run out of stock extremely fast.
Growing Monstera does not require anything fancier than your average houseplant, but you might need adequate space as it grows a lot bigger.
If you already have a healthy plant collection, you will do great! You can easily grow Monstera as it is low maintenance.
I hope this article is helpful to keep your Monstera Thai healthy and thriving. Happy gardening!
