However, when growing it indoors, watering is a crucial part if you want the Calathea majestica to look good. So how do you water a Calathea majestica? How often should a Calathea majestica be watered?

I. How to Water a Calathea majestica

The Calathea majestica has very broad leaves and a high water requirement, and once watering is insufficient, the leaves will wilt. So when it comes to how to water a Calathea majestica, you should water frequently to keep the potting soil moist, and the number of waterings should also change accordingly with the seasons: in spring and autumn, water once a day; in summer, water 3-4 times a day; in winter, water once every 2-3 days.

II. Watering Methods for the Calathea majestica

(1) Watering Principles for the Calathea majestica

The Calathea majestica likes a humid environment and is not drought-tolerant. Once watering is insufficient, it will cause the leaves of the Calathea majestica to curl; at the same time, the Calathea majestica is very afraid of waterlogging. Once overwatered, it can easily cause the leaves of the Calathea majestica to turn yellow, or even kill the plant. So when watering a Calathea majestica, you should follow the principle of “water when dry, and water thoroughly when you do.”

(2) How Often to Water a Calathea majestica

In the process of growing a Calathea majestica, as the temperature changes, the speed of water evaporation and the growth rate of the plant will slow down, so watering a Calathea majestica needs to change according to the seasons. As for how often to water a Calathea majestica, it can be divided by season, as follows:

1. Watering in Spring and Autumn, Once a Day

The Calathea majestica likes a warm environment. Late spring and early autumn are its fast growth periods, when it has a relatively high water requirement, so watering should be frequent, preferably once a day, to prevent water shortage.

2. Watering in Summer, 3-4 Times a Day

In summer, as the temperature rises, water evaporates faster, so the number of waterings for the Calathea majestica should be increased. As for how often to water a Calathea majestica, at this time it should be watered 3-4 times a day. The times can be chosen in the morning, at noon and in the evening, among which the morning is for cleaning the leaves, noon is for replenishing water, and evening is for caring for the plant.

3. Watering in Winter, Once Every 2-3 Days

After winter arrives, the growth of the Calathea majestica will slow down, and watering should be reduced at this time. As for how often to water a Calathea majestica, at this time, depending on the weather conditions, you can choose to water once a day.

Overall, the growing methods for the Calathea majestica are not difficult, but if you want to grow it well, watering must be done with proper methods. Watering is a technical skill, and if you want to become an experienced grower, you should practice it more. I believe it won't be long before you master it.

Can the Calathea majestica Be Grown in Water? Home Hydroponic Growing Methods and Precautions for the Calathea majestica

Most people like to grow some green plants at home, whether for decorating the home environment or for cultivating the mind, all of which are values brought by green plants. However, quite a few plant enthusiasts are no longer limited to soil potted plants; hydroponics is even more attractive. This is because hydroponic plants have high ornamental value, and mainly because they are also relatively simple to care for. So can the Calathea majestica be grown hydroponically? Today the editor will introduce it to everyone.

Can the Calathea majestica Be Grown in Water?

The Calathea majestica can be grown hydroponically.

Home Hydroponic Growing Methods and Precautions for the Calathea majestica

I. Home Hydroponic Growing Methods for the Calathea majestica

1. Hydroponic Preparation

The container can be a plastic pot, a ceramic flower pot, or a glass product. Choose a plant with robust growth, no dead leaves or yellow leaves, glossy leaves with bright colors, and no pests or diseases. The nutrient solution used for hydroponics can be a special nutrient solution for foliage plants or a compound flower fertilizer, used after dilution with water.

2. Hydroponic Method

Before hydroponics, first wash the roots of the Calathea majestica. Soak the plant in water close to the ambient temperature, with the water reaching about one-half or two-thirds of the root system. After the potting soil loosens and falls off, change to clean water and gently wash away the fine soil sticking to the root hairs.

Then remove the dead leaves from the plant, cut off the old roots or rotten roots, and soak in a 1% potassium permanganate aqueous solution for one hour. This not only disinfects and sterilizes, but also promotes the plant to grow new roots early. After taking it out, rinse it clean with clean water, then plant it in the container, add clean water and leave 1/3-1/2 of the root system exposed above the water surface.

Precautions

1. In the early stage after hydroponics, the leaves of the Calathea majestica may curl. Place the container in a ventilated and shady place, and spray the leaves with water appropriately. Change the clean water once every 1-2 days, and new roots will grow after about 10 days.

2. When the plant has adapted to the hydroponic environment and the leaves no longer curl, you can add nutrient solution for care. The first time you apply nutrient solution, dilute it 3-5 times. Replace the nutrient solution once every three to four weeks, and usually you only need to replenish water.

3. During the care process, if you find rotten roots on the Calathea majestica, cut them off in time and rinse the roots with water to prevent the breeding of pathogens.

What Are the Values of the Calathea majestica?

1. Greening Value

The Calathea majestica can be planted under trees in parks and along roadsides. In South China, the Calathea majestica has already been used on a large scale in landscaping, while in North China it is mostly planted in greenhouses for garden landscaping.

2. Decorative Value

The Calathea majestica can be planted in hotels, shopping malls, conference venues and other places by means of mass planting, clump planting or combined arrangement with other plants, and used for permanent arrangement in corner areas of public places.

But when planting indoors, pay attention to replenishing light in time, and spray water on the leaves on schedule to increase the air humidity in the environment.

3. Purification Value

As a leafy plant, the Calathea majestica also has a certain effect on purifying the air. It can absorb impurities and dust in the air and purify particulate matter, so it is one of the best choices for home growing.

4. Potted Value

Because the plant has a relatively beautiful appearance, many leaf colors and many colors, and relatively strong viability, it is relatively easy to cultivate and manage. It is often used for indoor potted ornamentation and is one of the most famous indoor foliage plants in the world.

For home growing, it can be placed on the balcony, in the living room, bedroom, etc. During cultivation, every once in a while, place the Calathea majestica in a place with relatively strong sunlight such as a balcony or outside a window, so that it can absorb scattered light, which is conducive to vigorous plant growth and convenient for long-term viewing.

How Often to Water a Calathea majestica

I. Watering Time

Generally, water three times a day, once each in the morning, at noon and in the evening.

II. Watering Methods

1. From March to October each year is the vigorous growth period of the Calathea majestica. The most suitable relative air humidity for its growth is 75%-85%. Higher air humidity is extremely beneficial to the leaf growth of the Calathea majestica, so it needs frequent watering.

2. In summer, water 3-4 times a day. It is best to spray the leaves in the morning, water the soil surface at noon or in the afternoon, and water the whole plant in the evening, and spray the leaves frequently.

3. In autumn and winter, the growth rate of the Calathea majestica slows down, and the amount of watering should gradually be reduced. Depending on different weather conditions, you can choose to water once a day or once every 2 or 3 days.

III. Precautions for Watering

1. When the Calathea majestica grows new leaves, if it is too dry, the edges of the leaves will curl and later become deformed, seriously affecting the ornamental effect, so be sure to pay attention to watering.

2. Watering in summer should also be moderate, following the principle of “small amounts, many times.” The soil should not be too sticky or too wet, otherwise the Calathea majestica is prone to root rot and disease.

3. When the temperature is relatively low, keep the soil dry to avoid the Calathea majestica being damaged by frost.

As mentioned above, the Calathea majestica can be grown hydroponically, and plant enthusiasts who need it can try the hydroponic method above. During hydroponics, root rot may be relatively likely, so plant enthusiasts should not forget to deal with rotten roots in time to avoid breeding bacteria.

Is the Calathea majestica Toxic? Can the Calathea majestica Be Placed in an Indoor Bedroom?

People nowadays all pursue health, so most of those who can will grow one or several pots of green plants at home to decorate the home and purify the air. Generally, green plants grown mainly for foliage have a very strong ability to purify the air, and the beautiful Calathea majestica has become the first choice for most people. But recently there have been rumors that the Calathea majestica is toxic, causing many people to worry. Today the editor will take everyone to learn the truth.

Is the Calathea majestica Toxic?

The Calathea majestica is not toxic. So far there is no clear information that can show it is a toxic plant. And according to veterans with many years of growing experience, the plant does not contain any toxin. However, apart from eating it, because no one has experimented with this. I think friends also have no intention of eating it.

Now let's talk about its smell. For many plants we cannot smell their scent, but this does not mean that the plant does not give off any smell. But the smell of this plant is not toxic; on the contrary, it can also purify our environment.

Can the Calathea majestica Be Placed in an Indoor Bedroom?

The Calathea majestica can be grown indoors. The benefit is that it can provide oxygen during the day, beautify the room, cultivate the mind, and increase indoor air humidity. The harm is that at night it competes with people for oxygen, but because the Calathea majestica is not large in plant size, its “harmfulness” is not high. In addition, the Calathea majestica likes a warm, humid and brightly lit growing environment, so when planting indoors, pay attention to replenishing light in time, and spray water on the leaves on schedule to increase the air humidity in the environment.

Growing Methods and Precautions for the Calathea majestica

I. Growing Methods

1. Temperature

The Calathea majestica likes a warm environment. The suitable growing temperature is 20℃-30℃, the best growth temperature during the day is 18℃-21℃, at night 16℃-18℃, and above 10℃ it can safely overwinter.

So in summer, prevent high-temperature sun exposure and place the Calathea majestica in a shady place. In winter, pay attention to cold protection and move the plant indoors.

2. Watering

The vigorous growth period of the Calathea majestica is from March to October. The air humidity should be maintained at 75%-85%. High air humidity is beneficial to leaf unfolding, so during the growth period it should be watered more and the leaves should be sprayed frequently. The suitable watering method is to spray the leaves in the morning, water the potting soil in the afternoon, and water the whole plant in the evening.

3. Light

The Calathea majestica is not tolerant of direct sunlight, so shade work should be done well in summer. Let the Calathea majestica absorb scattered light.

4. Soil

The Calathea majestica likes fertile, loose soil and does not like soil compaction or waterlogging. Generally, fertile humus soil and porous coarse media are used as the substrate.

5. Fertilization

Fertilization of the Calathea majestica should follow the principle of “small amounts, many times.” During the peak growth season, apply a mixed fertilizer of peanut bran and compound fertilizer or decomposed compost once every 2 weeks.

II. Precautions for Growing

1. Control the Amount of Watering According to the Season

In summer, plants have a high demand for water, so they should be watered 3-4 times a day. In autumn and winter, as the temperature drops, the growth rate of the Calathea majestica slows down, and the amount of watering should be reduced. You can water once a day or once every 2-3 days, and try to keep the soil dry.

2. Avoid Leaf Scorching

In summer, the sunlight is strong, and the leaves of the Calathea majestica are easily scorched under direct sunlight, so place the plant in a place without direct light. If you find that the leaves are scorched, cut off the leaves immediately to avoid the invasion of pathogens.

3. Reduce the Concentration of Fertilizer Solution

Stop fertilizing during the winter dormancy period and the hot summer period. The concentration of fertilization should not be too high, otherwise it will cause leaf scorching, and in severe cases the plant will die.

Reasons for Curling Leaves of the Calathea majestica

1. Too Much or Too Little Water

The Calathea majestica is relatively sensitive to water. If watering is too little or the air humidity is not enough, the leaves of the Calathea majestica will curl. During the new leaf growth period, if there is a lack of water, dry air will make it difficult for the new leaves to unfold, the leaf edges will scorch and turn yellow, and the leaves will be small and lack luster, seriously affecting the ornamental effect.

But if watering is too much and water accumulates seriously in the flower pot, the leaves of the Calathea majestica will also curl, the roots will rot, and the plant may even die.

2. Direct Sunlight

The Calathea majestica likes a semi-shady environment. Too strong light or direct sunlight will make the leaves of the Calathea majestica curl.

3. Invasion of Pests and Diseases

When the Calathea majestica is invaded by pathogens, the leaves will gradually curl and wither, and in severe cases the leaves will also fall off.

The Calathea majestica is not toxic. At least for now there is no clear information that can show it is toxic, so plant enthusiasts do not need to worry. The Calathea majestica is a plant very suitable for greening the home environment, but if you want it to grow well, you need to supplement its light in time.
