Stromanthe plant care: how to grow a stromanthe triostar plant

How to grow a Stromanthe triostar?

The most common question from newbies is “how do I grow a Stromanthe triostar?”

or “I want to start growing a Stromanthe triostar”. Most beginners don’t have any experience with plants so they ask their friends and family members for advice. Usually these people are not experienced at all about plants and sometimes even they don’t know what kind of plant it is! So before you go out there asking your friends and family, just think twice if you really need to grow one. You will probably regret it later.

There are many different types of plants that can be grown as houseplants. Some of them are succulents, cacti, ferns, mosses and lichens. There are also some other plants like dahlias and chrysanthemums which could be used as houseplants too but they require special conditions such as low light levels or humidity level to thrive well. So you can see that not every plant can be grown as a houseplant.

Some types of plants just don’t work well as houseplants because they need more specific growing requirements than other houseplants. Stromanthe triostar is one of these plants which require high light and humidity levels to thrive well.

Why do I want to grow a stromanthe triostar plant?

Should I grow a stromanthe triostar?”

Is another common question from people who are new to plants. It’s a good question to ask yourself because there are some factors that you should consider before growing a plant indoors. Stromanthe triostar is not the easiest plant to grow as a beginner because they need high light conditions and high humidity. If you live in an apartment or your house has low humidity then it might be very difficult to grow a stromanthe plant because many of them cannot handle low humidity well.

If you are a beginner then it is also best if you avoid growing plants that have high light requirements too. A stromanthe triostar requires a lot of light to thrive well so this type of plant would be very difficult for you if you cannot provide the proper lighting conditions.

How much light does a stromanthe triostar plant need?

Stromanthe triostar is a type of plant that likes high light conditions. If you cannot provide strong lighting for this plant then it will probably show some signs of weak growth and stretch. It will probably display some signs of yellowing or browning leaves too which is usually a sign that they aren’t receiving enough light. Overall the plant will not look as healthy and vibrant and this can also shorten the lifespan of this plant.Stromanthe triostar’s light requirements aren’t as high as other plants such as some types of cacti, succulents and euphorbias though.

If you want to know if your stromanthe is receiving enough light then just look for the following signs:

Spikes – how many spikes does it have?

Most stromanthe will have 3 spikes but some can have 5 or even 7 spikes. If you plant has 5 or more spikes then it most likely is receiving enough light.

Leaf Spots – Does it have leaf spots?

If your plant has dark leaf spots or blemishes then your stromanthe probably isn’t receiving enough light. These leaf spots are caused when the plant is either too cold or too hot.

Color – Is it a bright green?

A stromanthe that has low light conditions usually displays dull medium green leaves. If your plant’s leaves are a dark yellowish-green or a gray-green then it isn’t receiving enough light either.

Overall – Does it look vibrant and healthy?

If your plant doesn’t look very strong or vibrant then it probably isn’t receiving enough light. Most stromanthe that aren’t receiving enough light will display weak growth and stretched leaves that don’t look very firm.

How much water does a stromanthe triostar plant like?

Stromanthe plants are a little harder to kill with over watering but this can still be done easily. If you water this plant too much it will cause the roots to rot and eventually kill the plant. Stromanthe are a little more forgiving when it comes to under watering though. If you don’t water this plant for a prolonged period of time then its roots may start to suffer but unlike under watering, its leaves won’t discolor or droop as much. Stromanthe plants will typically absorb most of the water through their thick leathery leaves so watering this plant isn’t quite as important as it is with other plants.

If you do decide to water this plant, only water it when the soil dries out completely. Stromanthe can tolerate wet soil but this can cause root rot and eventually kill the plant. The best way to water this plant is to put your hands into the soil and feel how moist it is. If you think it needs water then sprinkle it with a little bit of water.

Don’t drench it though!

You can also place the pot in a tray that is full of rocks and about an inch or two of water. Allow the pot to sit in the rocks where it can catch the water as it drains. As long as the pot is catching the water and the soil is dry then your plant won’t receive too much water.

What kind of soil should I use?

Stromanthe triostar plants prefer a soil that is on the heavier side but still well draining. It can be beneficial to use a cactus and succulent potting mix because it doesn’t contain any chemicals or additives. Another good option is a regular potting soil that doesn’t contain any fertilizer or additives as well.

If you don’t have any of the above mentioned soils, just make your own by using equal parts clean sand, soil free compost and crushed limestone. Add a small handful of bone meal to help promote stronger roots as well.

This heavy soil helps to weigh down the plant’s fleshy leaves so that they can support their own weight better. If you choose to use a regular potting soil or just soil and compost then you may need to add a small handful of limestone or crushed oyster shell to the mixture in order to help weigh it down.

What is the ideal temperature for a stromanthe?

Stromanthe triostar plants can typically take a little more temperature change than most but that doesn’t mean you should expose it to extreme temperatures. This plant can typically take temperatures between 5 and 100 degrees Fahrenheit but only for short periods of time.

How far away should I place this plant from a window?

Stromanthe plants can grow to be quite large in time so you will want to start off by giving it a few feet of distance at first. A good starting point would be about 2 to 3 feet from a southern facing window. If you want to place it closer or farther away then make adjustments slowly and watch how the plant responds.

How often should I water my stromanthe?

As mentioned earlier, stromanthe plants can typically go for longer periods in between watering but you do not want its soil to dry out completely. The best way to know if it needs water is to stick your finger in the pot. If the soil feels completely dry then it’s time to water it. You can also wait for the leaves and edges of the pot to start flaking and curling which means that it is getting too dry.

If you do happen to overwater your plant then simply drain out the extra water from the bottom of the pot. It’s not good to let this sit in water for long periods of time because this can introduce disease into the soil.

What kind of sun exposure does a stromanthe like?

These plants typically enjoy more sun than they get indoors. They can typically take some shade but start to lose their vibrant color if they get too much. Since these plants are succulents, they can typically take more sun than other plants but this doesn’t mean you should place them in the direct path of the sun’s rays.

Ideally, place this plant about a few feet from a southern facing window. If you don’t have this kind of window in your home then an eastern or western facing window should work just fine as well since they still get some sun.

How can I tell if my stromanthe is root bound?

It’s very easy to tell if your stromanthe is root bound because its leaves will start curling and getting brown tips. This is a sign that the roots are being cramped and need to be pruned.

All you need to do is gently lift your plant out of its container and try to gently tease the roots apart. You don’t want to tease them too much so that they become unattached from each other but enough that they have more room within the container. This is also a good time to re-pot your plant into a bigger container.

What kind of fertilizer should I give my stromanthe?

You should only apply slow release fertilizer at half strength to your plant about once every two months. You should also avoid applying any kind of fertilizer that has copper in it since this can actually cause a toxic reaction to the plant.

How often should I re-pot my stromanthe?

Re-potting should typically be done every year or every other year. Since these plants can get so large over time you will eventually run out of space within the container. In addition, if your plant has started to grow taller rather than wider then it also might be a good idea to re-pot into a bigger pot as well.

Remember that these plants like dense soil so make sure you use a heavy soil when re-potting your plant. This will help prevent the plant from toppling over in windy conditions.

What do I do if my stromanthe gets infested with mealy bugs?

If you notice that your plant has white cotton like clusters on the top side of its leaves then it probably has an infestation of mealy bugs. These little pests are related to aphids and tend to attack plants that are weak and infested plants typically are already lacking in care.

All infested plants should be immediately isolated from all other plants so that the pests don’t spread. You will also need to wipe off the clusters of bugs with a soft cloth and a little bit of alcohol to kill them.

Since you probably also lack the care that the plant is lacking you should take extra special care of it until it starts looking healthy again. Typically the bugs will start to recede after you start taking good care of the plant.

My stromanthe’s leaves are falling off of it, what’s wrong with it?

If you notice that the tips of your plant’s leaves are starting to turn brown and they start to fall off then this is probably due to underwatering. The scales on this plant are very sensitive to any kind of moisture stress.

All you need to do is make sure that the soil is doesn’t dry out completely and keep an eye on it for a while since it may take a little while for the plant to respond to over watering.

My stromanthe’s leaves are falling off and it has brown spots on its leaves, what’s wrong with it?

If your plant has brown spots on its leaves or they are falling off completely then it probably has a fungal infection. Fungal infections typically start out as small spots but can quickly spread and destroy a whole plant if not treated.

The first thing you should do is give your plant a very thorough spray from top to bottom with a water misting can. Then put on some gloves to protect your hands and gently wipe off the scale insects that are cuddled up in the folds of the leaves with a Q-Tip. Be sure to dispose of the Q-Tip and any infected leaf that falls off in the trash, do not put them down the drain!

After you have removed as much as you can with your hands, use a cotton swab dipped in alcohol to get out any additional pests. Dispose of the swab in the trash as well as alcohol might be flammable, but it is great at killing off pests.

In order to address the fungal infection you will need to use two different solutions. Mix up a solution of water and bleach and spray the plant thoroughly with it. Be sure to protect your hands and eyes during this process and don’t breathe in the fumes either!

After the plant dries, mix up some fresh lemon juice (about 1 tsp) with a quart of water and pour it slowly over the scale insects. The lemon juice will help to disfigure them and also make them more vulnerable to your bleach attacks since they won’t be able to hold on as well.

Once they have been weakened you should be able to easily wipe most of them off the plant with your gloved hands. Be sure that the plant dries completely after this treatment, so you may want to prop it up so that all the leaves are exposed.

My stromanthes is yellowing, what’s wrong with it?

It sounds like your plant is lacking in magnesium. Stromanthe’s are really sensitive to this and it causes the yellowing of the leaves as well as the curling in on itself that you mentioned. It gets worse over time and can cause permanent damage. If you don’t want to replace the plant then your only option is to try to give it a good dose of Epsom salt. (Google it).

I hope this information helps you with your plant. If you need any more help just let me know!
