Placing a humidifier in the same room with the plant can also be beneficial especially during the winter months when the home environment may become drier.

Calathea lancifolia prefers well-draining soil that is slightly acidic and high in organic matter. A good potting mix for Calathea lancifolia will contain a combination of peat, bark, and/or compost. A soil pH of about 5.5 is ideal for this plant.

Fertilizing your Calathea lancifolia is essential to keep it healthy and growing. Fertilize your plant during the spring and summer months using a balanced fertilizer that has equal amounts of nitrogen, phosphorus and potassium. A liquid fertilizer such as compost tea, fish emulsion and/or seaweed extract is ideal. Dilute the solution to half-strength and use it every two weeks during the growing season.

Calathea lancifolia are generally quite pest free, however mealybugs can be a problem for these plants. Mealybugs are sap-sucking insects and can be easily identified by their white, cottony masses. Mealybugs can be removed by wiping the leaves with a cotton ball moistened with rubbing alcohol. Insecticidal soap can also be used, and it is recommended to monitor the plant closely to see if there is any further infestation.

Regular repotting helps your Calathea lancifolia stay healthy and thrive. Repot every two to three years during the spring in a pot that gives the plant plenty of space. Make sure to loosen the roots before repotting, pruning can be done during this time. Use loose, fertile soil and be sure to keep the out of direct sunlight for a few days after repotting.

Calathea lancifolia require minimal to no pruning. When pruning is necessary, only use pruning scissors to adjust the shape of the plant. Prune the plants in late spring or early summer and remember to cut the old leaves just above the soil. Pruning any old or damaged leaves will help to keep the plants looking healthy and robust.

Mulching is not necessary for Calathea lancifolia but it will help retain moisture in the soil and it will also help suppress weeds. Use a lightweight mulch such as bark chips or shredded leaves. Make sure to keep the mulch away from the stem of the plant.

Calathea lancifolia can easily be propagated by division. This is a method of propagation that involves taking a healthy, mature plant and dividing it into two or more parts, each with its own roots. Choose a healthy, mature plant, dig up the root ball and use a sharp knife to divide it into two or more sections. Replant each section in fresh potting soil.

Calathea lancifolia may benefit from a wooden stake or moss pole for support. This will help keep the plant upright and prevent it from becoming overgrown or leggy. The plant can also be trained to grow up the pole to create an interesting look.

Calathea lancifolia does not need a rest period, however, it will benefit from a few weeks of slightly decreased care. This means that you can reduce the amount of water and light that you provide to the plant. You should also reduce fertilizer and humidity if possible. This will allow the plant to rest and become more tolerant of stressors.

Calathea lancifolia is not particularly toxic to pets, however in rare cases, it can cause irritation of the mouth, lips, tongue and eyes if ingested. It is recommended to keep pets away from this plant.
