Calathea picturata Fertilizer (Feeding)

Feed Calathea picturata (Goeppertia picturata) with a balanced water-soluble fertilizer every 4 weeks through out the growing season.

Withhold feeding for Calathea picturata during the cold season as growth is minimal and feeding at this time can lead to fertilizer burn. Read more on how to feed houseplants.

Regularly, flush out accumulated chemicals (salts) from the soil by running a stream of water through the soil. Allow the stream of water to run for some time and repeat the process several times.

Repotting Calathea picturata

Repot Calathea picturata (Goeppertia picturata) every 2-3 years at the beginning of the growing season or when it becomes root-bound. Take care not to injure its delicate roots.

Use a pot one size larger than the current one and ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot and eventual death of the plant.

Before repotting, water the Calathea picturata thoroughly at least 1 day before to make it easier and also hasten establishment. A well hydrated plant suffers less repotting shock and takes a shorter time to take root.

If the plant is large and has outgrown its current pot, divide it into several sections and use the splits to propagate new plants.

Repotting may cause the leaves to droop but the plant will eventually recover once it takes root; in about 3-4 weeks.

Soil for Calathea picturata (Goeppertia picturata)

Calathea picturata (Goeppertia picturata) Propagation

Calathea picturata (Goeppertia picturata) is propagated by plant division at the beginning of the growing season during repotting. We have outlined herebelow Calathea picturata propagation by plant division. Read on.

How to propagate Calathea picturata by plant division

Water the Calathea picturata 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 out the Calathea picturata plant from its pot and divide it into several sections. Ensure each sections has adequate roots and at least 2-3 stems.

Select a 6 or 8 in. pot and ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.

Fill the pot with Calathea potting medium and make a hole in the center of the pot. Ensure that the hole is slightly wider than the root base of the Calathea picturata section.

Place the Calathea picturata section in the previously made hole and lightly firm the soil around the base while taking care not to bury it too deep; maintain the section at the same soil level it was in the previous pot.

Liberally water the soil until water comes out through the drainage holes. Cover the pots with clear polythene to create a greenhouse effect and maintain warm humid conditions which hasten establishment of the Calathea picturata plants.

Place the pots in a warm, well-lit place until new growth has emerged on the Calathea picturata sections.

Gradually remove the polythene over a period of two weeks to acclimatize the new Calathea picturata plants.

Maintain the soil moist until the new Calathea picturata plants are well established after which you can begin routine care.

Calathea picturata (Goeppertia picturata) Problems Indoors

Calathea picturata problems indoors are caused by cultural faults in lighting, humidity, watering and temperature among others. Continue reading for more on these problems, their remedies and solutions.

Calathea picturata drooping leaves

Calathea picturata drooping leaves are due to three possible causes. One possible cause of drooping leaves in Calathea picturata is too dry air (low humidity).

Calathea picturata is very sensitive to low air humidity. Use a hygrometer to monitor the humidity and maintain it at 50%-80% for optimum growth of the plant.

To raise humidity for Calathea picturata, set the pot on a wet pebble tray or use a cool mist humidifier. Read more on how to raise humidity for houseplants.

Calathea picturata can also be grown in a terrarium as a high humidity can be maintained in a terrarium. Read more on how to make a terrarium for houseplants.

The second possible cause of drooping leaves in Calathea picturata is incorrect watering; either overwatering (soggy soil) or underwatering.

Water your Calathea picturata liberally and maintain the soil consistently moist at all times during the growing season. Reduce watering during the cold season but do not allow the soil to dry out completely.

Also, ensure that the soil is free-draining and that the pot has a drainage hole to prevent the soil from getting soggy.

The third possible cause of drooping leaves in Calathea picturata is that the plant is root-bound. This means that the roots have filled the pot and there is very little soil to hold water when you water your plant. Therefore, there is no water for the plant to take up to the leaves. The leaves loss their stiffness and they droop.

Check the bottom of the pot for roots growing through the drainage hole. Repot the plant into a pot one size larger than the current one or divide it into several sections to propagate new plants.

Calathea picturata dying

Calathea picturata may die due to two possible reasons. One possible reason why your Calathea picturata is dying is root-rot which is brought about by soggy soil.

Take out the plant from its pot and inspect the roots. Brown-black mushy roots indicate root-rot, trim them off and treat the healthy roots with a fungicidal solution.

Disinfect the pot or use a fresh pot to repot the plant in fresh free-draining soil. Do not water the plant and keep it dry for some time before resuming watering. Read more on how to deal with root-rot here.

To prevent root-rot in the future, ensure that the pot has a drainage hole to prevent the soil from getting soggy. Also, do not overwater your plant during the cold season as growth is minimal at this time.

The second possible reason why your Calathea picturata is dying is pest infestations. Calathea picturata like other Calatheas is prone to 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.

Calathea picturata leaves appear washed out

Calathea picturata washed out leaves are due to exposure of the plant to hot direct sunlight. Calathea picturata grows best in medium to bright, indirect light away from direct sunshine.

Move Calathea picturata to a more shaded spot or instal a light curtain to protect it from direct sunlight to prevent its eventual death.

Calathea picturata curled, yellowing leaves

Calathea picturata curled and yellowing leaves are caused by incorrect watering; either overwatering (soggy soil) or underwatering.

Overwatering (soggy soil) causes the roots to die due to lack of oxygen in the soil. When the roots die they cannot take up water and therefore the leaves begin to curl, yellow and eventually die.

Underwatering implies that there is too little moisture in the soil and therefore, the plant has no water to take up to the leaves. Thus, the leaves begin to curl, yellow and eventually die if the situation is not corrected.

Water Calathea picturata thoroughly and keep the soil consistently moist during the growing season. Reduce watering in the cold season but do not allow the soil to dry out completely.

Also, ensure that the soil is free-draining and that the pot has a drainage hole to prevent the soil from getting soggy. Read more on how to water houseplants.

Calathea picturata brown, dry leaf tips and edges

Brown, dry leaf tips and edges in Calathea picturata are due to four possible causes. One possible cause of brown, dry leaf tips and edges in Calathea picturata is dry air (too little humidity).

Calathea picturata requires a humid environment inorder to thrive. To raise humidity for your Calathea, set the pot on a wet pebble tray or use a cool mist humidifier.

Calathea picturata can also be grown in the bathroom or other moist areas in the home where humidity is high. Read more on how to raise humidity for houseplants.

Calathea picturata is also ideal for a terrarium as a high humidity can be maintained in a terrarium. Read more on how to make a closed terrarium for houseplants.

The second cause of brown, dry leaf tips and edges in Calathea picturata which is accompanied by stunted growth is infestation by spider mites due to the air being too dry (low humidity).

Remove the dead growth and raise humidity for the plant (as outlined above) to discourage the pest infestations.

The third cause of brown, dry leaf tips and edges in Calathea picturata is watering it with hard water. Water your Calathea picturata with chlorine-free water only like rain water.

Like other Calathea, Calathea picturata is sensitive to chlorine and other chemicals dissolved in water and it responds with brown leaf tips and edges.

The fourth cause of brown, dry leaf tips and edges in Calathea picturata is accumulation of salts or chemicals in the soil. These chemicals may have originated from the water used for watering or from the fertilizers used.

Regularly, flush out accumulated chemicals (salts) from the soil by running a stream of water through the soil. Allow the stream of water to run for some time and repeat the process several times.

Calathea picturata pests

The common pests in Calathea picturata 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.

Calathea picturata diseases

Calathea picturata is prone to leaf spot disease due to the humid conditions in which it grows.

The disease is indicated by brown patches surrounded by a yellow halo. Isolate the affected plant to prevent spread to the other houseplants and treat it appropriately for the disease.
