Propagation of Pholisma Nutt. ex Hook.
Pholisma Nutt. ex Hook., commonly known as sandfood, is a parasitic plant that belongs to the family Convolvulaceae. It does not produce chlorophyll and depends on certain host plants for survival. Propagation of Pholisma Nutt. ex Hook. is a challenging task due to its unique growth habit. Here are the common methods of propagation:
1. Division
Propagation of Pholisma Nutt. ex Hook. through division is possible but quite challenging. This method is usually done during the active growing season when the plant has developed several new shoots from the main root system. The new shoots can be carefully separated from the parent plant using a sharp sterile knife or shears. This method requires a lot of care and attention to prevent damage to the new shoots and ensure their survival.
2. Seed Propagation
Seed propagation is another common method of propagating Pholisma Nutt. ex Hook. However, seeds are not easily available since the plant produces few flowers and fruits. The seeds also have a low germination rate since they require specific conditions to germinate. They need to be in contact with certain plant roots to trigger germination. Once germinated, seedlings can be transplanted into individual pots or directly into the soil. Seed propagation is a time-consuming process, and the plant may take several years to mature to a size where it can produce flowers and fruits.
3. Grafting
Grafting is another method of propagating Pholisma Nutt. ex Hook., but it is only ideal for experienced growers. It involves grafting the Pholisma Nutt. ex Hook. onto a host plant of the same family. This method is challenging and requires a lot of care since it's tricky to keep the graft in place and to manage the compatibility between the host and scion. Additionally, the success rate of grafting is quite low, and most enthusiasts opt to use the other propagation methods.
Overall, propagating Pholisma Nutt. ex Hook. is not a straightforward process and requires patience, care, and attention to detail. Growers are encouraged to be diligent in their propagation efforts to ensure the success of their projects.
