Stromanthe Triostar Care: Tips and Tricks

The Stromanthe Triostar, alternatively known as Stromanthe sanguinea ‘Triostar’, is a captivating houseplant from Brazil. This striking specimen, growing naturally on the rainforest floor, belongs to the Marantaceae family.

This family features several noteworthy members, such as marantas, calatheas, and tanates, commonly called the prayer plant family.

A Common Mislabeling: Calatheas or Stromanthe Triostar?

Prospective buyers should be vigilant, as this plant is frequently mislabeled and sold as a calathea due to its similar appearance. If you’re considering adding this captivating addition to your indoor plant collection, it’s important to be aware of this common mislabeling mistake that often occurs in local nurseries.

A Radiant Beauty

Possessing exceptional beauty, the Stromanthe Triostar could easily be regarded as one of the most visually pleasing houseplants. But beauty doesn’t come without its challenges.

The Finicky Nature of Prayer Plants

Much like its prayer plant relatives, the Stromanthe Triostar can be somewhat demanding to cultivate. Despite its lush and attractive appeal, it is infamous for its finicky growth habits. This trait makes it a challenging endeavor for even seasoned indoor gardeners. As such, be prepared to provide it with the appropriate care and attention that this plant demands.

Proactive Learning: The Journey to Mastering Prayer Plant Care

Even as I share some invaluable tips today, I’m still in the process of deepening my own understanding of prayer plant care. These plants are notoriously finicky, necessitating significant time to acclimatize to our home environment. The key takeaway here is the necessity for patience. These plants have evolved to thrive in rainforests and our homes present an incredibly different setting.

The Challenge of Adjusting to New Environments

The distinct disparity between a plant’s natural habitat and our homes means it takes time for them to adjust. Despite the challenge, with the right care, these exotic beauties can flourish.

Light Requirements: Understanding the Low-light Houseplants

As you might infer from their origins in the rainforest floor, these houseplants are low light tolerant. Direct sunlight could harm these plants, causing their leaves to curl up. Interestingly, the colors of these houseplants play a crucial role in their ability to photosynthesize in low light conditions.

The sunlight bounces off the pigments on the underside of the leaves, reflecting back through the leaf to optimize photosynthesis.

A Safe Choice for Pet Owners: Non-toxic Houseplants

Pet owners can breathe a sigh of relief. Both Stromanthes and prayer plants across the board are pet-friendly and non-toxic. That’s one less thing to worry about when adding these houseplants to your collection. So, if your pet, like my cat Muffin, develops an affinity for these plants, rest assured, they’re safe.

In conclusion, these low-light houseplants, despite their need for specific care and attention, are an excellent choice, particularly for pet owners. Their ability to thrive in less sunlight and their non-toxic nature add to their appeal.

However, remember to exercise patience, as acclimatizing these plants to your home environment can be a slow and meticulous process.

Tending to Your Prayer Plants

Prayer plants, owing to their rainforest origins, appreciate a moist environment. As a rule of thumb, they are accustomed to frequent rainfall and hence require consistent moisture. If you notice your prayer plant’s leaves curling inward from the edges, not to be confused with a new leaf unfurling, this could indicate insufficient water.

A Plant’s Call for Help

When you see your prayer plant leaves curling inward, check the soil. If it’s dry, watering the plant should rectify the issue. If the soil is still wet, consider assessing the amount of light your plant is receiving.

Reducing the exposure to light could help the leaves open back up, as they tend to curl inward to protect themselves from harsh sunlight. These plants are highly sensitive to direct sunlight, and their foliage can burn very easily.

Choosing the Right Soil

To ensure your prayer plant receives the necessary hydration, consider using a soil mix that’s moisture-retentive. A soil rich in coconut coir or peat moss could be ideal for retaining moisture, and limit the use of perlite or orchid bark to prevent excessive water drainage.

Selecting the Appropriate Pot: Terracotta vs. Plastic or Ceramic

Though I have my prayer plant in a terracotta pot, which suits my regular watering habits, it’s essential to remember that terracotta pots dry out quicker than ceramic or plastic planters.

If you struggle to keep up with watering your prayer plants, opt for a planter that retains more moisture, especially if you intend to place the plant in a less visible spot.

Best Water for Prayer Plants: Distilled or Filtered

When it comes to watering these houseplants, distilled or filtered water is the recommended choice. Tap water often contains additives such as fluoride and bromine, which can accumulate as these plants have a harder time transpiring these additives.

In conclusion, the watering needs of prayer plants can seem intricate, but with attention and regular care, it’s a task that can be mastered. Keeping an eye on the curling of leaves and adjusting light exposure and watering schedules accordingly can go a long way in ensuring your plant’s healthy growth.

Choosing the right soil and pot, along with using appropriate water, can help mimic the moist environment these plants naturally thrive in.

Dealing with Water Additives

In addition to fluoride and bromine, chlorine in tap water can also lead to detrimental effects on prayer plants. These elements don’t easily transpire out, which often results in brown leaf tips. While I personally don’t mind a few brown tips and usually use tap water, striving for perfection in your plants would necessitate the use of distilled or filtered water.

Humidity Preferences

Being native to rainforests, prayer plants naturally favor high humidity. While they can adapt to typical household humidity during summer, they might face challenges during the winter when heating systems dry out the indoor air. I personally struggle with maintaining high humidity during winter and tend not to supplement it much.

This, however, is not ideal for these plants.

Recognizing Humidity Problems

One easy way to discern if your plant is unhappy with the humidity level is the appearance of brown edges on the leaves. If you notice this, it’s a clear sign your prayer plant could do with more humidity.

In conclusion, attention to details like the type of water and humidity levels can play a huge role in successfully caring for your prayer plants. The use of distilled water and maintaining a humid environment, particularly during dry winters, can significantly enhance the health and appearance of these plants.

Remember, if brown tips or edges appear, it’s time to reassess your plant’s care.

Recognizing and Treating Brown Leaves

If you’re noticing brown leaves on your prayer plants, it’s time for a quick assessment. Brown leaf tips can indicate a need to change the type of water you’re using, whereas brown edges may suggest the need for additional humidity.

Acclimating Your Plant

For a quick fix, you can use a large clear plastic bag. Cover your planter with this bag to create a micro-environment with higher humidity, replicating the conditions the prayer plant is accustomed to. It’s advised to keep the bag vented to provide a balanced humidity level.

After a few weeks, you can remove the bag, and your plant should have acclimated to its surroundings and be able to cope with standard household humidity. While this method does mean covering your plant for some time, the end result is well worth it.

Dealing with Pests: The Spider Mite Issue

One downside to prayer plants is their susceptibility to spider mites. Some varieties, especially those with thinner leaves, seem to attract these pests. While the thicker-leaved Stromanthe sanguinea isn’t typically the first to get infested, if you already have spider mites in your home, they are likely to find their way to these plants.

Typically, these mites will make their home on the undersides of the leaves. You’ll spot them as small specks, possibly accompanied by some webbing. While they won’t cause immediate harm, a significant infestation can start to sap your plant’s vitality, leading to speckled yellow spots and an overall less healthy appearance.

The beauty of these plants lies in their vibrant foliage, which is undoubtedly their main appeal. Maintaining this appeal means vigilance against pests and keen attention to their water and humidity needs. By following these guidelines, you can enjoy the stunning beauty of the prayer plants in your home.

Avoid Repotting During Winter Months

While it’s tempting to repot your Stromanthe or other prayer plants during the winter, it’s best to avoid doing so. The shorter, colder days are not conducive to plant adaptation, especially after being uprooted from the comfortable greenhouse conditions they’re accustomed to.

Waiting for longer, warmer, and more humid days will give your plant a better chance to acclimate to its new surroundings.

To Propagate or Not to Propagate?

Propagating these plants is possible, but not necessarily recommended. Given their finicky nature, if your plant is thriving in its container, it might be best to leave it alone. However, if the plant has overgrown and is producing numerous pups or offshoots, propagation by division could be an option.

This process involves separating the offshoots from the soil, similar to how you would with a snake plant. While it is doable, remember to proceed with caution as the plant can be sensitive to changes. For instance, this Stromanthe plant I received from a friend was propagated from an offshoot.

Initially, it looked great, but soon the leaves turned yellow and brown as the plant struggled to acclimate to its new home.

Understanding the Plant’s Resilience

One notable characteristic of this houseplant is its resilient, tuberous root system. The roots contain rhizomes, potato-like structures that store a significant amount of energy. So, if your plant appears to be dying back rapidly after bringing it home, or it suddenly declines during the winter months despite your best efforts, don’t panic.

The energy stored in the rhizomes may give the plant a second life, even if you have an empty planter for a month or two. Patience is key when dealing with these striking, yet sometimes challenging, houseplants.

Embrace New Growth and Acclimation

It’s important to remember that if you continue to provide proper care for your prayer plant, it will likely generate new growth from its rhizomes. This is precisely what happened with the Stromanthe plant I received as a gift from a friend. Initially, the plant seemed to decline rapidly, but with time and care, it put forth new shoots that have fully acclimated to my space.

Even though we’re currently in the midst of winter in Philadelphia, and I’m not providing any additional humidity, the leaves show no signs of browning at the edges. This is a testament to how well they’ve acclimated to my home conditions.

Final Thoughts

One crucial piece of advice I’d like to leave you with is that patience is paramount when caring for prayer plants. There may be times when the plant doesn’t look its best, tempting you to give up on it.

However, if you remain patient and consistent in your care, you might end up with a remarkably vibrant plant. This is a lesson I’ve learned from my own experiences with various prayer plants.
