Propagation of Crinum strictum Herbert var. traubii Moldenke
Crinum strictum Herbert var. traubii Moldenke, also known as Traub's River Lily, is a plant species that belongs to the Amaryllidaceae family. The plant is native to South America and can be found in areas with high rainfall and near rivers or swamps. Propagating Traub's River Lily can be done through different methods, which are:
Propagating by Division
Propagation by division is the easiest way to propagate Traub's River Lily. This method involves separating the plant's offset from the parent plant and planting it in a new pot or area. The offset should have its roots already formed or be big enough to develop new roots after planting. It is important to ensure that the new pot or area has fertile moist soil and receives indirect sun. The planting depth for Traub's River Lily should be at least 3 inches, and the plant should be watered thoroughly after planting.
Propagating by Seeds
Propagation by seeds is another method to propagate Traub's River Lily. This method will require more time and patience than propagation by division. The seeds should be planted in spring or early summer, in a pot or area with fertile moist soil, and placed in a sunny location. The seeds should be covered with a thin layer of soil and watered thoroughly. It is essential to maintain the soil moist during the germination period, which can take from a few weeks to a few months. Once the seedlings are big enough to handle, they can be transplanted to a new area or pot with fertile soil.
Propagating by Bulbs
Propagation by bulbs is another method that can be used to propagate Traub's River Lily. This method involves planting a bulb that has already formed by the parent plant. The bulb should be planted in a pot or area with moist fertile soil, and the planting depth should be at least 6 inches. The bulb should be watered thoroughly after planting and maintained moist until the plant starts to sprout. Traub's River Lily can grow from bulbs for several years, and it is essential to ensure that the soil is well drained to avoid causing root rot.
