Calathea Sanguinea Features

Foliage and Stem

The leaves of Calathea Triostar Pink are the beauty of this plant. It has large exquisite green leaves with pink and creamy variegations and purple undersides. What a lovely combination! One cool feature of the leaves is that they fold at night and uncurl back at dawn.

Evergreen

Calathea Sanguinea is an evergreen plant that stays fresh and green throughout the year. Its foliage does not shed all at once in autumn; it sheds its leaves randomly all year round.

Calathea Sanguinea Height

This plant can attain a height of 2 to 3 feet at most; it happens in the ideal conditions only. Its foliage occupies about 1-2 feet in width.

Temperature Tolerance

Like other houseplants, this Calathea plant does not like temperature extremes. It is cold-hardy to some extent, but it should not be left outdoors in extreme winters in frost. Your plant is winter-hardy but not frost-hardy at all.

In the same way, higher temperatures also harm the beautiful foliage of this appealing plant. Extreme heat burns its leaves and damages the vibrant colors of this plant. You can grow it in a bathroom where the temperature stays lower than in the other rooms.

Humidity Tolerance

Calathea Sanguinea can tolerate high humidity. But too much high humidity or low humid environments are intolerable by this plant. In low humidity, its leaves start to get dry and brown edges, while in high humidity, its leaves get fungal diseases.

Drought Resistance

This lovely species is not much tolerant of droughts. If it does not get regular watering, its leaves start to lose their freshness and become floppy. This is why you should keep watering the plant regularly to prevent it from any period of droughts.

Disease and Pest Resistance

Luckily, Calathea Sanguinea Triostar is resistant to diseases. It is a robust plant that stands stronger in the face of many bacterial or infectious diseases. However, it is susceptible to fungal diseases. If it is grown in higher humidity than its optimum needs, it gets fungal diseases. Also, avoid misting this plant as it also welcomes fungus. If your plant gets any such disease, remove the infected part to prevent the disease from spreading to other healthy parts.

Aphids are the only pests that can attack this plant. You should use insecticide, bacterial soaps, or neem oil to get rid of these pests.

Calathea Sanguinea Growth

This plant grows at a moderate rate. It still grows faster than other houseplants. Its growth rate greatly depends on the conditions in which it is grown. If you want to increase its growth rate, you must grow it in ideal conditions.

The ideal USDA plant hardiness growth zones are 10 to 12.

Toxicity

One of the great features that we love about this plant is that it is a non-toxic species. Its foliage and stem are completely harmless to any pet or humans. You can easily handle this plant without wearing gloves, as the leaves do not cause any irritation like some other houseplants.

Maintenance

This beautiful species is loved as a houseplant because it is a low-maintenance plant; you need not look after it every day. It just asks for its basic needs. If you provide it with the bare minimum care needs that it asks for, it is good to go! It thrives and grows on its own.

Dormancy

If your Calathea Triostar Pink stops growing in winters and is not producing any new leaves, then do not worry. It is just in its resting stage. In winters, this plant goes dormant and has stunted growth. These days, its watering needs to decrease, and it does not need any fertilizer either.

Calathea Sanguinea Care

The care routine of the Calathea Sanguinea plant involves watering it thrice a week and fertilizing it thrice a year with a liquid fertilizer. It should be grown in a well-draining potting mix (pH 6.0-8.0). The temperature must be kept around 64-81°F for this plant.

Water Requirements

It should be watered thrice every week. Calathea Sanguinea loves moist soil, so you should water it more often in summers and spring. As soon as its topsoil gets dry, give it a thorough watering using lukewarm water. In winters, its watering frequency must be cut down to once per week or once every ten days.

If you keep this Calathea plant over a pebble tray to increase humidity for it, never let the water level reach its drainage hole. This is because this plant hates standing water, and it will easily get root rot.

Calathea Sanguinea Soil

Calathea Stromanthe Tricolor must be grown in well-draining soil that has good aeration and more organic content. The soil pH could be slightly acidic to slightly alkaline. The preferred pH range is 6.0-8.0. The soil type that stays in this pH range can retain more nutrients and minerals for the plant.

For the potting mix, you can use a mixture of perlite and peat moss. These two ingredients are great for increasing drainage and aeration. Peat moss also maintains the pH of the potting soil. Use two parts of peat moss and one part perlite to make the perfect potting mix for this beautiful Calathea plant.

Calathea Sanguinea Sunlight

To find the perfect spot to place your Calathea plant’s pot, you must examine its light exposure in its natural habitat. This plant grows under the many trees in the forest, where sunlight is filtered through their thick canopy. This is the clue; this plant loves dappled shade. You should place it in a spot in your home where it receives dappled sunlight, or you can say bright, indirect sunlight.

An east or north-facing window is the best place for its placement. If you want to grow this plant outdoors, you must protect it from the direct sun through a shade cloth. If the pretty foliage of Calathea Triostar is exposed to direct sunlight, brown spots start to appear on its leaves.

Temperature Requirements

As this lovely species is a tropical plant, it prefers warmer temperatures. The ideal temperature range for this plant is from 65°F (18°C) to 80°F (27°C). We recommend you to grow this tropical plant indoors where the temperature does not fluctuate much and stays in this ideal range. If you live in a colder region, where the temperature stays lower than average, you can grow this beauty in a greenhouse or a terrarium.

Humidity

Just like every other tropical, rainforest-native, greeny plant that loves high moisture in the air, Calathea Sanguinea also loves to grow in high humidity. The humidity level must be kept above 50% to provide this plant with the ideal growing conditions. A high moisture level is necessary for this plant for the bright, vibrant colors of its foliage. If the humidity drops below the optimum level, the edges of its leaves start to turn brown and lose their beautiful shades.

You can increase the humidity for this plant by trying different methods. You can either install a humidifier in your room or place this plant over a pebble tray. Grouping it with other houseplants also helps in increasing the moisture level around this plant.

Fertilizer

Calathea Sanguinea is not a heavy feeder. It does not need to be fertilized occasionally. It should be fertilized only thrice a year with a slow-release, liquid fertilizer. Liquid fertilizer is available to the plant’s roots for an elongated period so no need for occasional fertilization.

You can also use the regular houseplant fertilizer to feed this plant. This fertilizer must be added every month. But never fertilize this plant in winters. This is because this plant is dormant in winters, and any extra nutrients will cause salt build-up in the soil and kill the plant eventually.

Grooming and Pruning

This plant does not necessarily need any pruning. It maintains its gorgeous appearance and shape all year long. However, you still have to remove any dead or old leaves now and then. Before every growing season or at the beginning of spring, cut its leaves from the bottom part of its stem. This practice will also encourage more growth and more branching. Keep in mind to always disinfect your pruning shears before using them on your plant. Non-sterilized scissors can make this plant susceptible to infectious diseases.

Repotting

Calathea Stromanthe Sanguinea needs repotting when it has outgrown its previous pot, or when its roots start to grow out of its drainage hole. This does not happen every year. Whenever you re-pot your plant, make sure you move it to a pot that is not so much bigger than the previous one. A pot that is only one size bigger than the old pot would be enough. The best time for this plant repotting is late spring to early summer.

Calathea Sanguinea Propagation

Propagation of Calathea Sanguinea feels obligatory as this plant is so pretty to be kept alone. It must be propagated to increase its collection and adorn indoors with those small babies. You should propagate this plant from mid-spring to late summer. If you have never propagated a plant before and have no idea what to do, we are here to help.
