What is the Monstera Thai Constellation?

What is the Monstera Thai Constellation

Thai constellations look very much like the parent family of the Monstera, but their leaves are unique in that they are variegated. This feature makes them a beautiful adornment to most indoor and outdoor spaces.

The Monstera Thai Constellation was born in a lab! It is the result of carefully curated lab conditions, with the propagation of Monstera tissue.

The original Monstera plants originated in Thailand and are more commonly found in Panama and Mexico. The creation of this plant in the lab with unique features and tissues means that the plant’s foliage is a sight to behold.

The marbled foliage characterizes the Monstera Thai Constellation, with the plant growing up to heights crossing 20 feet! The plant is light green and dark green because the distribution of chlorophyll across the plant is unequal.

The Monstera Thai Constellation is also interspersed beautifully with holes in the leaves that may be as small as 2 inches and as large as up to 12 inches wide.

The Monstera Thai Constellation is not confused with the variegated Monstera Deliciosa Borsigiana since the variegation on the Deliciosa is very likely to reduce with time. This is not the case with the Monstera Thai.

Thai Monstera Constellation Propagation

The only preferable and less labor-intensive way of growing the Monstera Thai at home is to do it with propagation. The several methods of propagating the plant are listed below:

Monstera Thai Propagation by Air Layering

This is a generally unique propagation method, but it is easy and fail-proof. This is because the aerial roots resulting from this method increase the plant’s adaptability to both garden spaces and any new containers in which they are kept.

Firstly, select a healthy stem and use clean, sharp gardening tools to make a small cut at the node. If you are unsure of the exact process, watching a video or consulting an expert is necessary to avoid damaging your plant.

Use damp moss as a bandage, and wrap it around the cut you made, making sure it gets into place tightly. You can use a piece of plastic with some string or rope tied around it to secure the moss in place.

Next, wait a couple of weeks to remove the plastic around the cut. This time, remove the entirety of the item you selected. This stem can now be used for propagating more of the Monstera Thai Constellation plant!

Propagating Thai Constellation Monstera By Stem Cuttings

The following best method for propagation is stem cuttings from the parent Monstera Thai Constellation plant. For this, you should use the correct size of pruning shears, making sure they are sterilized, to cut a segment of the stem.

You should leave at least a third of the branch intact. The best time to undergo this process is during spring or summer, so the plant can quickly and easily replace the trimmed-out part. 

Leaving leaves and aerial roots in the plant also ensures rapid growth. Next, select the correct pot and soil mixture to plant the stem segment you took from the parent place.

You can even plant the cutting in water, wait for root development and then transfer it into a pot later. You can add seaweed and light, organic plant food to give it an edge along the growing process. 

The best location to undertake the propagation procedure is anywhere there is lots of sunshine! If you are propagating the stem in water first, change the water regularly. 

It will take the stem around 4-6 weeks to grow roots, and at this point, you can transfer it to the pot or the ground directly.

Monstera Thai Constellation Propagation by Separation

Monstera Thai Constellation can very much overtake your other bushes and is very prone to overgrowth. For this reason, propagation by separation not only ensures a good division of your plant across multiple locations but prevents it from overrunning your entire garden.

To propagate via separation, prepare beforehand by watering your plant in advance and waiting for it to completely dry. Next, if the plant is potted, use your hands to loosen the soil from the very bottom and lift the plant out from the pot. 

Make sure to do this gently and not rip up the root base in the process. Next, use a large knife to separate the soil, dividing the roots into two or more segments of the plant.

Make sure to not rip through large segments of stems and leaves. Instead just separate them from the other parts of the plant carefully, still attached to the stem.

After your segments are separated with the root ball attached, you can repot them. Make sure the soil and water conditions are ideal since the cutting needs a spurt of growth on its own, separated from the parent plant.

Watering Requirements

The Monstera Thai Constellation is a plant that doesn’t like showers of water and especially dislikes mushy, waterlogged soil. The maximum time you should be watering the Monstera Thai Constellation is once a week.

During the winters, the Monstera Thai Constellation requires fewer nutrients, so you shouldn’t be giving it any booster food or fertilizer at all. Giving it fertilizer during this time can result in fertilizer burn, and that can be deadly to the plant.

Soil Requirements

Monstera Thai Constellations are quite particular about the soil conditions they prefer to grow in. The best consistency of soil should be moist and grainy, not mushy and watery.

Soil with high organic matter and additional perlite to assist draining also keep the plant healthy and strong. Peaty soils in pots that have a draining mechanism prevent waterlogging in the plant and also ensure that nutrients in the soil aren’t run off and wasted.

The pH levels required for the soil are around 5.5-7.0, so there can be some variation from acidic soil to neutral soil.

Pruning Monstera Thai Constellation

The Monstera Thai Constellation requires less pruning, making it a convenient indoor plant. Pruning is recommended to manage the plant's size and to remove dead or damaged leaves.

Before you begin, disinfect your cleaning tool with isopropyl liquid or alcohol swabs. This prevents cross-contamination between the different plants you own and handle.

If your Monstera plant has grown too huge, you can trim it to control its growth, but be sure to cut away only what's necessary. Pruning also aids with infection management.

To regulate the health of your plants, remove diseased plant sections. Make sure to wear gloves while pruning, since the sap from the foliage can cause skin irritation.
