Propagation Methods for Calathea lutea (Aubl.) G.F.W. Mey.
Calathea lutea (Aubl.) G.F.W. Mey. is a perennial evergreen plant that belongs to the Marantaceae family. It is native to the tropical forests of Central and South America. The plant is popularly grown indoors because of its unique foliage patterns, which makes it an ornamental houseplant. Propagation of Calathea lutea can be done by several methods.
Propagation through Division
Division is the most common method of propagating Calathea lutea. The plant can be easily propagated through this method because it naturally produces offsets. It is best to divide the plant during the early spring or summer. Select a healthy and mature plant, loosen the soil around its rootball, and gently pull it out. Carefully separate the offsets, making sure that each division has an equal portion of rhizome and roots. Plant the new divisions in individual pots with well-draining soil to avoid root rot.
Propagation by Seeds
Propagation by seeds is another way of multiplying Calathea lutea, but it can be challenging. The plant's inflorescence produces small fruits that contain seeds. Seeds can be extracted and sowed in a potting mix. Keep the soil moist and place it in a warm and bright area, but avoid direct sunlight. Germination can take several weeks to months, and transplants should be done when the plant has reached maturity.
Propagation through Rhizome Cuttings
Propagation through rhizome cuttings requires careful handling because the plant's rhizomes are fragile. Select a healthy plant and carefully remove part of the rhizome. Cut the rhizome vertically into two or three sections, making sure each section has at least one bud and an adequate amount of roots. Plant each section in a pot with well-draining soil, and place it in a bright, but indirect sunlight location. Water the new plants sparingly to avoid the development of root rot.
