Propagation of Rollandia lanceolata Gaud. var. viridiflora Rock
Rollandia lanceolata Gaud. var. viridiflora Rock is a plant species commonly found in the Philippines. It belongs to the family Asteraceae and is commonly known as "pak-aw" or "pako."
There are different methods for propagating Rollandia lanceolata Gaud. var. viridiflora Rock. These include:
Propagation by Stem Cuttings
Using stem cuttings is one way to propagate Rollandia lanceolata Gaud. var. viridiflora Rock. Simply cut a stem about 4-6 inches in length from a healthy mother plant. Remove all leaves except for the top two or three leaves. Dip the stem cutting in rooting hormone powder and plant it in a pot filled with a well-draining soil mixture. Keep the soil moist and place the pot in a shaded area. After a month or two, the stem cutting will develop roots and can be transplanted to a larger container or directly to the ground.
Propagation by Division
Another way to propagate Rollandia lanceolata Gaud. var. viridiflora Rock is through division. This method is suitable for plants that have multiple stems growing from the ground. Carefully dig up the plant and separate the stems by gently pulling them apart or using a sharp knife. Be sure to keep a portion of the parent plant attached to each stem division. Plant each division in a pot or directly to the ground. Water the new plants thoroughly and keep them in a shaded area until they become established.
Propagation by Seeds
Rollandia lanceolata Gaud. var. viridiflora Rock can also be propagated by seeds. Collect the seeds from a mature plant and plant them in a well-draining soil mixture. Cover the seeds with a thin layer of soil and keep the soil moist. Place the pot in a shaded area and wait for the seeds to germinate. After the seedlings develop two to three leaves, they can be transplanted to a larger container or directly to the ground.
