Calathea plants have various names, such as prayer plants, peacock plants, rattlesnake plants, zebra plants, and cathedral plants. These plants belong to the arrowroot family Marantaceae.

Calathea is native to tropical parts of Latin America, such as Bolivia, Columbia, Panama, and Puerto Rico, among others. They have since been introduced to Hawaii and grow well in the warm climate there.


When it comes to light requirements, Calathea prefers low to medium light. Indoors 6-8 hours of bright indirect light is perfect. Direct sunlight can be harmful and cause damage like sunburn or dullness in the color of the leaves. If you’re placing your plant near a window, make sure to use a sheer curtain or provide some kind of shade so that it doesn’t receive too much direct sunlight. Additionally, place your Calathea away from any heat sources, such as radiators and air conditioners, which can also harm the plant by drying out its leaves. With proper care and attention, this genus will thrive indoors!

Water Requirements

If you are using a Naked Root planter, you can follow a 14-day watering schedule for Calathea plants.

Calathea plants require a humid environment and are sensitive to the quality of their water. Tap water may cause their leaf tips to turn brown, so it is best to use filtered or distilled water at room temperature. If distilled water is not available, leave a container of water out for 24 hours before use. The soil should be consistently moist but not soaked. Do not wet the leaves, and only water when the top inch or two of the soil feels dry.


Calathea plants like high humidity. They live in rainforests naturally, so place them near a humidifier. If you don’t have that option, a people tray can be beneficial. It also helps to group humidity-loving plants together so they can conserve moisture.


Calathea plants will go into a dormancy stage if the temperature drops below 65°F. Because they are native to tropical regions, they are happiest at 70-75°F.


Calathea plants are non-toxic to both humans and animals. You can grow them around your kittens and toddlers without worry.

Pests and Diseases

Spider mites, aphids, mealybugs, and scale insects are the most common pests that can affect a Calathea plant. Neem oil and insecticidal soap can be used to treat these insects. To get rid of them, you can use an alcohol-soaked q-tip to remove them from the plant and then spray the plant with either neem or insecticidal soap.

Leaf spots caused by Psuedomonas and blight can manifest as water spots on the plant’s leaves. Applying a copper fungicide can get rid of leaf spot, including Alternaria leaf spot and helminthosporium leaf spot, but there is no known treatment for Psuedomonas blight. To ensure the spread of the disease does not reach other plants, dispose of the infected plant and its soil.

Calathea plants may be susceptible to Fusarium wilt, a fungal disease that leads to the yellowing and wilting of leaves, with browning of the stem veins. To slow the spread of the disease, try drenching treatments of copper fungicide. However, the only way to fully eliminate it is to get rid of the infected soil.


Adequate drainage is a must, as Calathea plants have root nodules that are fleshy and can rot in overly moist soil. They do especially well in air root pruning containers, as this environment stimulates the growth of hundreds of tiny feeder roots. This, in turn, prevents root rot and keeps the plant from becoming pot-bound.


Good soil is essential for calathea and should be kept moist but not wet and should have good drainage. African violet potting soil is a great choice for calathea, and a mix of peat moss, perlite, and potting soil/fine compost can be used as well. Avoid mulching, as this can damage the roots. Small amounts of worm castings and organic matter can help retain moisture. A drainage hole in the container is necessary.


Calathea plants don’t require a lot of fertilizing, typically only during the growing season, which runs from the beginning of spring to the end of fall. Use half a teaspoon of kelp fertilizer per 32 ounces of distilled water once each month, replacing regular watering with this solution. Distribute the liter over a period of time, not all at once.

If your plant’s leaves are becoming yellow or if it is drooping and wilting, this may be an indication that you have fertilized too much. These may also be signs of inadequate fertilizing, so use caution. If your plant’s leaves are yellowing after monthly fertilizing, reduce the frequency.

Calathea is susceptible to salt damage. If you are using a commercial fertilizer, dilute it, and at least once per season, flush the soil with several gallons of water to remove any salt buildup.


Unlike other plants in the Marantaceae family, it is not always possible to propagate calathea plants by taking cuttings from a mother plant. Additionally, since most species of calathea will not produce seeds when grown indoors, propagation by seed is not an option. Therefore, the best way to propagate calathea plants is by dividing them during repotting.

Moisten the soil in the planters you wish to use. Carefully take the calathea out of its original container and remove any extra dirt. Examine the roots and stems where they connect, then delicately separate them with some leaves. Place each new plant in a container and cover the roots with soil at the same level as before. Finish by topping off the pots with a bit more of the potting mix.


If desired, pruning is only needed for aesthetic purposes. If a leaf has turned yellow due to age or has brown edges, it can be carefully snipped off with a clean and sterile pair of pruning shears just above the soil. Do not trim the central leaves. Brown tips on leaves are a common occurrence, so trim the brown edge off the leaf, and the rest should be fine. Once the flower stalks have faded, cut them off so your plant can focus its energy on growing new flowers.

The whole plant reaches 18-22 inches tall.
  10. Calathea Roseopicta ‘Rosey’ – This cultivar is similar to its parent, but the leaves are pink! Each leaf is striped in cream and edged in dark green, with a dark purple underside. The total plant is the same size as its mother, about 20 inches tall. For optimal health of your ‘Rosey,’ ensure that the soil is consistently moist and nutrient-rich and that it offers good drainage. Maintain your home’s temperature above 65°F and make sure to avoid exposing it to any chilly drafts.

Summary of Calathea Plant Care

Calathea thrives in warm indoor temperatures ranging between 65°F and 80°F and can be damaged by temperatures that get too low. It needs consistently moist soil with good drainage and high humidity to prevent browning or curling of the leaves. Salt sensitivity is common in Calatheas, so fertilize with a half-strength, water-soluble houseplant fertilizer no more than monthly during the growing season, and flush the soil regularly to remove any salt buildup. Cold drafts should also be avoided, and bright filtered light is best for optimal growth and leaf color. Too little light can result in leggy plants, and too much direct sunlight can burn the foliage.
