Monstera Thai Constellation Price
Why is the Thai constellation so expensive?
The Monstera Thai Constellation is a very in-demand and expensive plant. Because of this demand it costs a lot, especially in recent times where houseplant demand in general has gone up as the hobby in general has got more popular. At the same time supply has not increased.
They go on Etsy for 250-500 euros/dollars and upwards for a relatively small but established plant. Some for over a thousand!
Costa Farms Thai Constellation
Update: Costa Farms have now officially announced that their Monstera Thai Constellation will be on sale in 2023 (source).
The Thai Constellation is very likely to come down in price soon, as an American producer, Costa Farms, is mass propagating a crop as I write. This will most likely lead to a drop in price globally, but don’t expect it to go for pennies, it will still be an in-demand plant but some should crop up in 2023 for 100 euros/dollars or a bit less if you’re lucky. Then after these come to market there will likely be more people trading the plants in plant shops and online platforms like Etsy and Ebay.
Monstera Thai Constellation For Sale
You can buy these from private sellers, plant shops and Ebay etc, I got mine from Etsy, they always seem to have some and I got mine for a good price on there.
How To Propagate Monstera Thai Constellation
These are expensive plants and you want the prop to go as well as possible, so I would use sphagnum moss, but protect against fungus gnats by covering the top surface with LECA clay balls. I would guard against over watering and root rot by using pots with holes in (like normal plant pots, por make holes in the container you have). You do not want to cut a fresh new growth off the plant immediately, but wait a month for it to get to a good size and for the left to harden a bit.
Once you take the cutting (just below the node), leave it for half a day for the wounds to callous over before potting it up in moist moss. Keep the moss moist and make sure it is kept humid and well lit but change the air daily and avoid full sun). A plant cabinet is ideal, but I use large plastic storage boxes with a cheap LED grow light on the top and a humidity meter inside, and I leave the top about 20% off so air can circulate.
They should root relatively quickly and once you see new leaf growth you can treat it as a juvenile plant. At this stage I would transfer it to LECA and then after a month or so start using semi-hydroponic fertilizers. Once you get used to using LECA it is really easy with much fewer pests than soil.

Monstera Thai Constellation Care
To care for your Monstera Thai Constellation you should keep it moist, but not waterlogged as that can lead to root rot. Let it almost dry out between waterings, especially in winter when root rot is a higher possibility.
You can treat them similarly to a normal Monstera Deliciosa. However make sure to keep it out of sunlight as it is more sensitive to burning due to the variegation, but give it plenty of indirect sunlight.
Give it indirect sunlight, it needs as much energy as it can get without burning the leaves, so a grow light or indirect sun is ideal.
How Often to Water
Water the when the top half of the soil is dry, check it once a week. Tip any excess water out from the external pot ten minutes after watering. They do not want to sit in soggy soil, but they do not want to totally dry out either, so checking them weekly is a good idea.
Use a balanced feed, well diluted, once a month in summer.
Rich, well draining aroid mix with perlite, potting compost and orchid bark in equal parts.

When To Repot
Check the roots every year at about Easter time and give the plant a new pot if they are starting to get crowded. You want it to have plenty of room to grow over the warmer growing months.
60% or more is ideal. They can get crispy leaves if not.
Tip: keep them humid or the leaves can brown, a humidity meter will help to monitor the minimum leaves so you know it is not drying out at any points.
Aim for 17-23°C (63-73°F), do not let them get below 5°C (41°F) at night
How To Increase Variegation In Monstera Thai Constellation
You cannot directly increase the variegation, but you can encourage it by giving it as much indirect sunlight as you can.
How Fast Do Monstera Thai Constellation Grow?
They grow fast for their size. Not as fast as a normal deliciosa, but they can grow 50cm in a year (almost 2 feet).
Is It Toxic To Cats?
They are toxic to cats if eaten, and can cause vomiting and numbness. So seek vets advice immediately if your pet eats any.
Monstera Thai Constellation USDA Zone
They can grow outside in zones 10-11. Keep them shaded from full sun.
Over watering is a really common issue, as well as lack of humidity, and sunburn if given direct sun. But if you give it the care already mentioned in this article you should avoid all these common issues.
Monstera Thai Constellation Vs Albo
The Thai Constellation has lots of small splashed and dashes of white and off-white variegation, almost like it has had a white paint brush flicked at it. But the Albo Variegata has bigger areas of variegation too, sometimes they have totally white leaves, (or half a leaf) which I’m sure you’ve seen all over Instagram. Both a great variegated plants, the Thai Constellation has the more stable variegation though and is less likely to revert.
Can Monstera Thai Constellation Revert?
It can revert, but it is rare as these plants are tissue cultured and tested with a stable variegation. If you get some leaves that are less variegated than normal, give the plant some more light and cut the less variegated leaves off back to the node to encourage a stronger variegation on the next growth.
How Does Monstera Thai Constellation Grow?
These plants grow 300-600 cms a year (1 or 2 feet), given the right conditions. Thai Constellation Monstera’s like these grow upright to an extent, but will spread out and hang down eventually. The best way to keep it upright is to tie it carefully to a moss pole.
Can I make my Monstera variegated?
In short, you cannot make a Monstera variegated. Naturally occurring new variegation is a very, very rare event, it is like playing the lottery. So it is much easier to take cuttings from a variegated plant.
Can a regular Monstera become variegated?
Yes – but it is about 1 in 100000 chance of a monstera becoming variegated naturally. So it is very unlikely.
The elusive Monstera Thai constellation is a rare houseplant enthusiast’s dream plant, and although expensive, is set to drop in price and become more available over the coming years.
