Stromanthe triostar (Stromanthe sanguinea) thrives in bright, indirect light, warm and humid conditions and consistently moist, rich, well-drained soil coupled with monthly feeding during the growing season.
Stromanthe sanguinea requires regular pruning to keep it neat and tidy as well as rejuvenate growth. Repotting is only necessary when it becomes pot-bound as it grows best when slightly root-bound. Keep reading for more on these growing conditions and how to achieve them.
Stromanthe triostar grows best in bright, indirect light. Too little light will result in loss of the beautiful variegation.
Keep it away from direct sunlight as it can lead to sunburn on leaves and washed out leaves.
Regularly turn the pot to ensure that the plant receives light on all sides for uniform growth and prevent leggy growth.
Triostar Stromanthe will also grow under a grow light where natural light is inadequate.
Water Stromanthe triostar thoroughly and keep the soil moist at all times during the growing season. Reduce watering in the cold season as growth is minimal at this time.
Being a tropical plant, water the Triostar Stromanthe with water that is at room temperature to avoid shocking the plant which can result in reduced growth.
This plant is sensitive to chemicals dissolved in water, therefore, water with water that is free of chlorine and flourides.
Ensure the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot.
Avoid wetting the foliage during watering or water from the bottom instead to prevent fungal infestation.
Stromanthe triostar prefers average warmth with a minimum of 130C. Protect it from cold draughts and sudden changes in temperature.
Stromanthe triostar requires high humidity inorder to thrive. To raise humidity, set the pot on a wet pebble tray or use a cool mist humidifier.
You can also grow Triostar Stromanthe in a terrarium as a high humidity can be maintained in a terrarium.
Clean the leaves of Stromanthe by damp-wiping with a soft cloth to keep them clean and neat.
Feed Stromanthe triostar with a balanced, liquid fertilizer once monthly through out the growing season for lush growth.
Withhold feeding during the cold season as growth is minimal and feeding at this time can lead to fertilizer burn.p>
Repot Stromanthe triostar the beginning of the growing season only when it has become root-bound. Use a pot 1 size larger than the current one.
Stromanthe does not like to sit in soggy soil, therefore, ensure the soil is free-draining and the pot has a drainage hole as soggy soil can lead to root-rot.
The large Stromanthe plants can be divided at the time of repotting and the splits used to propagate new plants.
Pruning Stromanthe triostar is easy as it involves removal of dead and yellow foliage to maintain the plant neat and attractive.
Cut back the stems at the beginning of the growing season to rejuvenate growth.
Stromanthe sanguinea propagation can be done at the beginning of the growing season by plant division.
Water the Stromanthe triostar thoroughly at least 1 day before to make it easier to divide and also hasten establishment. A well hydrated plant suffers less shock and takes a shorter time to take root.
Take the Stromanthe triostar out of its pot and divide it into several sections. Ensure each section has some roots inorder to hasten rooting.
Pot the sections into individual pots in moist, free-draining soil. Ensure the pots have a drainage hole to prevent the soil from getting soggy as it can lead to rotting.
Cover the pots with clear polythene to create a greenhouse effect and maintain warm humid conditions which hasten establishment of the plants.
Place the pots in a warm, well-lit place until new growth has emerged in the sections.
Gradually remove the polythene cover over a period of two weeks to acclimatize the new plants.
Then move the set up to a cool, shaded place and maintain the soil moist until the new Stromanthe sanguinea are well established after which routine care can begin.

Stromanthe sanguinea problems indoors include brown leaf tips and edges, rotting, discolored leaves, stunted growth, pests and diseases among others. Keep reading for more on these problems and how to fix them.
Stromanthe triostar brown leaf tips and edges is due to too dry air (low humidity) as it is very sensitive to low air humidity.
To raise humidity, set the pot on a wet pebble tray or use a cool mist humidifier. Check out these techniques on how to raise humidity for houseplants.
Stromanthe triostar can also be grown in a terrarium where high humidity can be maintained easily. Read more on how to make a terrarium for houseplants.
Stromanthe triostar limp and rotting stems are due to too cold air and or too wet soil. At this point, the plant may be too far gone to be saved.
To prevent limp and rotting stems in Stromanthe triostar, maintain an average warmth with a minimum of 130C. Protect your plant from cold draughts and sudden changes in temperature.
Also, avoid soggy soil by ensuring that the pot has a drainage hole and that the soil is free-draining.
Stromanthe triostar discolored or scorched leaves are due to exposure to direct sunlight on your plant. Move the plant to a shaded spot or protect it from direct sunlight to prevent eventual death.
Stromanthe triostar curled, spotted leaves and lower leaves yellowing are due to underwatering.
Water Triostar Stromanthe thoroughly and keep the soil moist at all times during the growing season. Do not let the soil dry out between waterings but reduce watering during the cold season.
Stromanthe triostar brown and dry leaf tips accompanied by stunted growth are an indication of spider mite infestation due to the air being too dry.
Remove the dead growth and set the pot on a wet pebble tray to raise humidity. Check out these techniques on how to raise humidity for houseplants.
Common pests in Stromanthe triostar are mealy bugs, aphids, scale insects and spider mites. Isolate the affected plant to prevent spread to the other houseplants and treat it appropriately for the pests. Read on how to treat root-rot in houseplants.
Stromanthe triostar is prone to leaf spot disease due to the humid conditions that it prefers. Isolate the affected plant to prevent spread to the other houseplants and treat it appropriately for the disease.
Stromanthe sanguinea (Stromanthe triostar) is non-toxic to both humans and pets. They are safe to grow indoors.
