What Makes a Deliciosa Thai Constellation Monstera so Special?
Other than the uniqueness of each of the leaves of Monstera Thai Constellation featuring variegation, the rare qualities of this plant also extend to the way it is cultivated. It is set apart from other Variegated Monstera varieties because it is produced in a laboratory in Thailand.
Unsurprisingly, production of a Thai Constellation plant is limited, so when these plants – usually a cutting – come onto the market, they are always sold to the highest bidder and usually only to collectors. In terms of value, it is not uncommon for a Monstera Thai Constellation cutting to fetch an eye-watering four-figure sum at auction.
Monstera Thai Constellation is also the only variety of Monstera Deliciosa Variagata that is known to not lose its variegation once propagated. In essence, it is 100% stable. Whereas, the seeds of other varieties do not always mutate upon germination.
When you add up their cult status and rarity, along with the unique properties of their foliage and photogenic attributes, it is easy to see how demand for these beauties has sky-rocketed in recent years. Factor into that how relatively easy to care for a Thai Constellation can be, it is no wonder that they are the most popular variety of Variegated Monstera available.
In this article we share all the tips and tricks you’ll need to care for your own Thai Constellation Monstera. Read on to find out more.
Monstera Thai Constellation Care
Most plants have chlorophyll-rich green leaves that are able to effectively absorb light. Through the process of photosynthesis, this light becomes energy that supports the growth and health of the plant.
However, as with all variegated plants, Monstera Deliciosa Thai Constellation has to work much harder in order to photosynthesize. This is because the yellow and white areas of the leaves contain no chlorophyll.
For this reason, a Variegated Monstera needs plenty of bright natural light to enable it to thrive.
If you are one of the lucky few to own Monstera Deliciosa Thai Constellation or are looking to add one to your house plant collection, then keeping it in tip-top condition will undoubtedly be a priority. In most respects, it needs the same care and attention as a standard Monstera. However, to enable it to thrive it does need a sweet spot with maximum natural light to give it a helping hand with light absorption. Here are our recommendations for meeting all the care needs of a Thai Constellation plant.
Monstera Deliciosa Thai Constellation Position
No Monstera Variegata will thank you for a position in direct sunlight. Their delicate leaves can easily become irreversibly damaged and burned. They do need a bright, naturally well-lit spot and somewhere away from draughts in order to thrive. It’s also beneficial to rotate your plant often. This will provide each leaf with the opportunity to absorb as much light as possible.
Humidity also plays a big part in growing a healthier and stronger Monstera Thai Constellation plant. Ensure that humidity levels are switched up to 60% or above. A greenhouse or warm conservatory is a great spot but if that’s not an option then find a warm, sun-facing room that benefits from plenty of natural light (the bigger the window the better) such as a kitchen or bathroom.
Variegated Monstera Thai Constellation Height And Spread
These plants are typically slow growers when compared to standard Monstera plants. With just a little patience, good light and humidity conditions, well-draining soil, and good watering habits the vining stems of an indoor-grown Monstera Deliciosa Thai Constellation can reach 8 ft long. Individual leaf length ranges from 3 inches to 12 inches depending on the maturity of the plant and the conditions it is kept in.
Watering A Monstera Thai Constellation Plant
The watering needs of Monstera Deliciosa Thai Constellation are no different from other Monstera plants. They need a thorough soak when the soil is nearly dry and not to be given an opportunity to stand in damp soil for prolonged periods as this could encourage root rot. It’s best to use a long spouted watering can that can get between foliage and reach directly into the soil.
A common mistake that is often made and one which can lead to over-watering is sticking rigidly to a regular watering schedule. This is because there are a number of variables that will affect how often you need to water your Thai Constellation Monstera. Changes in temperature, the amount of light your plant is getting and seasons of the year all play a part.
A far better method to understanding your plant’s watering needs is to be guided by the amount of moisture in your plant’s soil. You can test moisture levels either by using a soil pH tester kit or by placing your finger 2 inches below the level of the soil. If the soil is dry on the surface and slightly damp when your finger is fully immersed in the soil, then it is time to water your plant. If the soil feels damp both above and below the surface then hold off watering your plant and test again in 2-3 days.
In addition to watering, you may need to mist the leaves of your plant every 3-4 days to help with humidity. If you live in a particularly dry area or if it is not possible to achieve 60% plus levels of humidity then it is worth investing in a humidifier. It’s also a good idea to group your Thai Constellation Monstera with other humidity-loving plants as the moisture that evaporates via each plant’s leaves will help to bring up humidity levels slightly.
Choosing the Right Soil For a Monstera Thai Constellation
Monstera Deliciosa Thai Constellation needs to be planted in a well-draining potting mix that is rich in nutrients. Opt for a peat-based and coconut coir mix combined with perlite and bark for best results. Roots need to be free from excess moisture in order to encourage healthy growth and to avoid root rot.
All Monstera plants do well in a slightly acidic pH level soil. A range within 5.5 to 6.5 is ideal and will promote healthy growth throughout the growing season. Using a soil pH tester will provide you with quick and accurate results to make sure you have the right soil balance for your plants.
You can buy good quality potting mixes from any decent garden supply retailer or online store and there are plenty of options available. You may need to add more grit or perlite to further encourage drainage.
It’s also easy and cost effective to make your own well-draining potting mix at home. You will need one-third organic matter such as peat-based soil and coconut coir mixed with one third of minerals such as grit or perlite and four parts pine or orchid bark.
It is also well worth having a conversation with the seller to find out what soil mix they use for their Monstera Thai Constellation cuttings.
Fertilizer for Monstera Thai Constellation
Use best quality liquid fertilizer you can find with a 10-10-10 ratio once per month from Spring until the end of the growing season in Autumn.
Your Monstera Thai Constellation plant will thank you for an extra boost of nutrients on a regular basis throughout the growing season but won’t need feeding during the winter dormant period.
As a slow grower, a Thai Constellation plant should only need pruning annually and this is best done in Spring or Autumn. Trimming back any unruly, damaged, or discolored leaves should be sufficient to keep your plant looking healthy and to promote new growth.
Always use a sterile and sharp knife or pair of scissors and cut just above a node or as close to the main stem as possible.
A little extra care and attention is needed when repotting Monstera Thai Constellation because like all varieties of Monstera they are prone to stress and damaged roots during the repotting process.
You can mitigate this stress somewhat by re-potting during the growing season when your plant is in its growing prime. Summer is ideal and will give your plant the best chances of recovering.
Always re-pot two days after you last watered your plant. The moistened roots will come away from the sides of the pot easier than if you are pulling at dry roots that can easily fracture and become damaged.
Ease the plant from the pot being careful not to pull on the stems as these can become easily damaged. It’s best to tip the pot on its side and loosen the soil around the edges of the pot with your finger. This will make it easier to slide the plant from the pot or container.
When the plant has been lifted out of the pot, remove as much soil as possible from the roots by carefully brushing it away. With your fingers
While the roots are exposed, now is a good time to give them a thorough inspection. You’re looking for roots that are firm to the touch and cream or white in color. Roots that are brown or black and are soft and mushy need to be trimmed away as this is a sure sign of root rot.
When it comes to repotting, choose a pot or container that is just slighter larger than the previous pot. It needs to have good-sized drainage holes and you should always use fresh well-draining potting soil.
Bury the roots and just enough of the stem to enable the plant to stand upright. Press the soil around the stem gently but avoid covering it too much. Use a moss pole or trellis to wrap the stems around and with a short time the ariel roots of your plant will re-establish themselves in order to secure the plant to the supporting structure.
Monstera plants notoriously need a little adjustment time in new pots so expect a slightly hindered growth rate after repotting. Fear not! After about 4-6 weeks your plant will recover and you will begin to see new growth again.
Common Problems With Monstera Deliciosa Thai Constellation Plants
Monstera Deliciosa Thai Constellation plants can be prone to the occasional infestation from Whitefly, Mealybugs, and Scale. This is largely due to the humid environment they need to survive. These pests are unsightly and inconvenient but they are unlikely to cause long-term damage to your plant provided you act quickly as soon as you spot them.
To treat an infestation in the early stages, use a wet cotton tip, cotton pad or clean cloth to gently dab away all visible traces of these pests. Take time to check under leaves and between leaf and stem nodes for any stubborn bugs that may be lurking.
Follow this up by using neem oil, soapy water, or if you prefer a watered-down household insect spray or detergent to wash as much of the remaining infestation away.
You can repeat step one daily but only repeat step two every 4-5 days. Do this until all signs have subsided.
You should also move your infected plant away from all your other plants. Keep them separated until all signs of infestation have been cleared. Once you’ve treated the main problem check your other plants for signs of an infestation too.
