Calathea is a very popular indoor potted plant with beautiful leaves and good ornamental value. However, for many beginners, caring for Calathea can be quite challenging. In this article, we will introduce you to the care techniques for Calathea in detail, allowing you to easily cultivate healthy Calatheas.
Choose suitable soil.
Calathea needs to grow in nutrient-rich and well-draining soil. When planting Calathea, we can choose a soil mixture with good permeability, such as one mixed with peat moss and perlite, to ensure that Calathea can grow smoothly.
Maintain appropriate moisture levels.
Although Calathea requires a relatively moist environment to grow, overwatering can damage its roots. When caring for Calathea, we need to control the frequency and amount of watering, and increase watering during summer to ensure that Calathea can grow in a moist environment.
Control fertilizer usage.
Calathea has a relatively low demand for fertilizer, so we need to pay attention to the dosage when fertilizing. We can choose fertilizers containing elements like phosphorus and potassium to help Calathea grow better.
Control room temperature.
The optimal room temperature for Calathea growth is between 18-25°C. Both excessively high and low temperatures will affect its growth. We can control the room temperature by adjusting air conditioners or heaters to ensure that Calathea grows at an appropriate temperature.
Properly trim leaves.
During the growth process of Calathea, leaf density often becomes excessive. At this time, we can appropriately prune the leaves to make the branches more spread out, which also promotes its growth.
Maintain good ventilation.
Calathea needs a well-ventilated environment to grow. When caring for Calathea, we should frequently open windows for ventilation to ensure that Calathea can grow in a well-ventilated environment.
Avoid direct sunlight.
Calathea cannot tolerate direct sunlight, so we can place it in a semi-shaded location. We can also adjust its placement during summer to keep it away from direct sunlight and protect its leaves.
Pay attention to pest and disease prevention.
Calathea is susceptible to some pests and diseases, such as aphids and spider mites. When caring for Calathea, we need to prevent pests and diseases, and we can use biological or chemical pesticides for control.
Regularly replace soil.
Calathea needs regular soil replacement to remove residual nutrients and bacteria, ensuring root health. Soil replacement can be done in spring or autumn.
Avoid frequent movement.
Calathea is very sensitive to environmental changes, and frequent moving will have a certain impact on its growth. Be extra careful when moving Calathea and try to minimize the number of moves.
Pay attention to moderate shading.
Calathea needs a moderately shaded environment to grow, but excessive shading will affect its photosynthesis. When providing shade for Calathea, we need to properly control the density and height of the shading objects to ensure normal growth.
Keep the potting environment clean.
Calathea needs to grow in a clean environment. When caring for Calathea, we should regularly clear fallen leaves and weeds around the pot, and promptly remove accumulated water on the soil surface to maintain a clean growing environment.
Avoid exposing Calathea to cold air.
Calathea is not tolerant of cold, and if exposed to cold air, its leaves may wilt and turn yellow. During winter, we need to move Calathea to a warm indoor environment to protect its healthy growth.
Control Calathea's growth rate.
Calathea grows quickly. If not pruned or controlled in a timely manner, its shape will become unattractive. When caring for Calathea, we need to prune its branches appropriately to control its growth rate, ensuring a beautiful and healthy shape.
