Propagation of Raphionacme Excisa Schltr.
Raphionacme Excisa Schltr. can be propagated through various methods:
Seed propagation
The preferred method of propagation is through seeds. It is recommended to collect the seeds during the dry season. The seed pods should be left on the plant until they turn brown and begin to split open. Once the seeds have been collected, they can be sown immediately or stored in a cool, dark place until ready to be sown. The seeds should be sown in a well-draining soil mix and kept moist. Germination can take anywhere from 1 to 3 months. Once the seedlings have reached a suitable size, they can be transplanted into individual pots.
Cuttings
Raphionacme Excisa Schltr. can also be propagated through stem cuttings. Cuttings should be taken during the growing season from healthy, mature plants. The cutting should be around 10cm in length and should have at least two nodes. The cutting should be left to dry out for a day or two before being planted in a well-draining soil mix. The cutting should be kept moist and placed in a warm, humid location. Rooting should occur within a few weeks, and once the cutting has established roots, it can be transplanted into an individual pot.
Division
Raphionacme Excisa Schltr. can also be propagated through division. This method is best suited for older, more established plants. The plant should be carefully dug up and divided into smaller sections, each with its own set of roots. The divided sections can then be replanted into individual pots, each with a well-draining soil mix. It is essential to keep the newly transplanted plants moist and in a warm, humid location until they have established roots.
