Have I caught your attention? Let’s find out more captivating facts about Cigar Calathea!

Does This Plant Have Any Specific Light Requirements?

Calathea Lutea is a species that grows up to 13 feet in nature. With their extremely large leaves, they can absorb a larger amount of sunlight. They can be stored as houseplants, but only if you can provide extremely bright conditions.

Leaves can often grow unevenly or at strange angles, depending on how they face the light source. It is best to have a light source from above, like from ceiling windows.

In the jungle, this species grows under other trees so their light source has to pass through dense tropical canopies. This creates naturally filtered light and prevents leaf burns on Calathea Lutea.

Calathea Lutea likes partial sunlight

It is recommended to grow a Cuban Cigar in the garden, positioned in soft light or partial Sun. They can tolerate bright suns well in the first half of the day, but if you leave them for too long it could be harmful. In areas with high humidity, Calathea Lutea can stay in almost full Sun. The upper surface of the leaves is green, but the lower is whitish and slightly waxy for the protection of the heat.

If you have left it in the Sun for too long, and the climate is not so humid, don’t worry! Like most Calatheas, these species can regenerate and easily recover if they have been damaged under the Sun. Of course, try to prevent this by placing your Calathea Lutea in the right spot!

What are the Optimal Temperature and Humidity Levels?

Calathea plant comes from the tropical parts of the world and enjoys temperatures ranging from 65 to 80 degrees Fahrenheit. Slightly twisted leaves will be the first sign that your plant isn’t enjoying current conditions. Most often, this issue occurs when temperatures vary too much. With a thermometer, you will have no problem keeping conditions for your Calathea Lutea stable.

This species feels best in warm and humid weather. The indoor room temperature should not be lower than 60 ºF, and the plant should not be kept in rooms with a lot of drafts. Tropical and subtropical climatic conditions are the most suitable for growing this plant. It usually blooms from spring to summer, but in warmer regions, you can expect flowering throughout the year.

It is sensitive to low temperatures, so if you live in a changing climate, this plant must spend the winter indoors, with lots of light and moderate watering. Feel free to mist these plants regularly to maintain high humidity. This will prevent the edges of the leaves of your Calathea Lutea from turning yellow and keep the whole stem healthy and hydrated.

Cuban Cigar prefers moist areas. With their broad, rich, and green leaves, they absorb moisture through the air. It is necessary to maintain the humidity level above 70%. If you maintain at least 50% relative humidity during the year, the plant will grow successfully. If the leaves darken at the tops or start to fall off in the worst case, it means that the air conditions are too dry.

How to Propagate Successfully?

The easiest way to propagate Calathea plants is by dividing. These houseplants tend to grow better when divided and transplanted in early spring before the growing season.

Calathea Lutea is not propagated by stem or leaf cuttings. These species are not suitable for this method of reproduction. Stem cuttings do not contain the necessary plant tissue for the growth of new roots and the development of an individual plant.

A few days before you plan to divide, water the soil thoroughly. Remove the whole Calathea Lutea from the pot and gently clean the soil from the roots. Carefully separate the root system and divide it with a sharp incision with pruning shears. Make sure that each cluster has its root system and that the leaves are still on the stem. If everything seems fine, you are free to transfer the new plant into a separate pot and take proper care of it.

The adjustment period after the propagation of Calathea Lutea is crucial. Keep the soil moist but don’t make it soggy. Maintain steady conditions, warm and humid environment. Cover the new seedlings with a plastic tent to create a greenhouse effect and increase the humidity.

Add nitrogen fertilizer to the previously moistened soil to encourage growth. Use a diluted mixture every two weeks or once a month. Within a few weeks, you will be able to proudly show off your new Calathea Lutea.

Fertilization Do’s and Don’t’s

Calathea Luthea requires regular nutrition. To encourage growth in the early spring, feed your plant once a month with liquid fertilizer.

An aggressive influx of fertilizer at that time can damage the roots and make it difficult for your plant to re-establish itself.

Use a balanced fertilizer in an equal ratio of phosphorus, nitrogen, and potassium. Before fertilizing, be sure to water the plant to protect the roots, the first 3 inches of the soil should be moderately moist.

Watch out for the accumulation of excess salt in the soil. If you notice some damage along the edges of the leaves, stop feeding immediately. Eliminate excess salt by rinsing the entire soil of the plant and then lightly dry it. Place the plant in fresh, new soil and avoid feeding for some time.

As for trimming, this plant does not require routine pruning. Damaged or aged leaves that have turned yellow should be cut off for the Calathea Lutea to develop new healthy leaves more easily. Damaged leaves slow down the general growth, and at the same time, they are not aesthetically pleasing.

Common Problems and Solutions

Calathea like many tropical plants can occasionally have uninvited guests. The most common are spider mites, fungal mosquitoes, scale, and mealybugs.

Spider mites are big fans of Calatheas in general, and Calathea Lutea is not an exception. They appear mainly in winter due to dry air. Fortunately, you can easily remove them by increasing the humidity by misting your plant more frequently. Humidity levels above 50% will ensure they don’t come back.

Unlike spider mites, soggy soil can invite fungal mosquitoes. On the surface of the soil, you will notice tiny pests that feed the root of the plant. Stop watering immediately and allow the soil to dry well. You can also add 3% hydrogen peroxide diluted by water to the substrate.

Beware the mealybugs!

These tiny pests are difficult to eradicate because they sneak into the soil or tiny cracks in the stems. Calathea will suddenly begin to lose vitality and energy, so it is important to react quickly when you notice these pests. Use Neem oil as a natural alternative or insecticide to make sure it won’t come back.

Yellow leaves are a common occurrence in the Calathea plant and can have a variety of causes. One of the issues that cause this phenomenon is leaf chlorosis.
