  First: cultivation environment. Calathea orbifolia likes a high-temperature and humid environment and has strong shade tolerance. It grows well under indoor diffused light and should be cultivated in loose, fertile, well-drained soil.


  Second: growing temperature and humidity. ① Temperature.The optimal growing temperature for Calathea orbifolia is around 22°C. When the summer temperature is above 35°C, not only does the plant stop growing, but the leaf color also turns yellow and loses its ornamental value. However, in winter, be sure to keep it warm and protected from the cold, and the room temperature should be kept above 13°C.
② Humidity.The suitable air humidity for Calathea orbifolia is 70%-75%. When new leaves are emerging, the humidity requirement is even higher, and it should be watered thoroughly to keep the soil moist. In winter, watering should be controlled, and the potting soil only needs to be slightly moist.


  Third: choosing a pot and fertilizing. ① Choosing a pot.Calathea orbifolia is a shallow-rooted plant, so the growing container should be a wide-mouthed shallow pot to help the root system extend and spread. Generally, repotting is done at the turn of spring and summer together with division propagation, once every 2 years.
  ② Fertilizing.During the peak growing season, Calathea orbifolia should be given a dilute liquid fertilizer once every half month. When fertilizing, be careful not to apply too much nitrogen fertilizer, so as to avoid the leaf markings fading.


  Fourth: propagation.Calathea orbifolia is mostly propagated by division, carried out in spring from April to May together with repotting and soil changing. If division is done too early and the temperature is too low, the wounds heal slowly, which easily causes rot and lowers the survival rate.

   The following are several situations in which yellow leaves appear on Calathea orbifolia; yellow leaves occur in these situations.
  1. Water-yellow:Tender leaves are dull yellow and lack luster, old leaves show no obvious change, stems are thin and yellow-green, and new shoots shrink and stop growing, indicating overwatering.

Scorch-yellow:When strong direct sunlight shines on some shade-loving flowers (such as spider plant, Calathea orbifolia, hosta, etc.), it easily causes the leaf tips and leaf edges of the flowers to wither, and yellow spots appear on the parts of the leaves facing the sun. Just move it to a shaded place.
  4. Fertilizer-yellow:Yellowing of flowers caused by too much fertilizer or too high concentration shows as dry brown tips on new leaves. Generally, the leaf surface is thick and lacks luster, and is uneven and not smooth, while old leaves scorch yellow and fall off. Fertilizing should be stopped immediately, and in severe cases, a large amount of clean water should be used to wash out part of the fertilizer.
