Propagation of Hermannia arabica Hochst. & Steud. ex Fisch.
Hermannia arabica Hochst. & Steud. ex Fisch., also known as Arabian Hermannia or Arabic Candyweed, is a shrub that is native to Africa and can be propagated through various methods:
Seed Propagation
Seeds of Hermannia arabica can be propagated through direct sowing in well-draining soil during spring. The seeds must be sown at a depth of 1 cm and watered regularly to maintain soil moisture. Germination can take place within two to four weeks, with the seedlings being ready for transplanting in individual pots in about six weeks.
Cuttings Propagation
Hermannia arabica can also be propagated through cuttings, particularly during the summer season. Softwood cuttings can be taken from the parent plant, usually measuring between 7-10 cm in length. The base of the cutting must be dipped in a rooting hormone before planting in well-draining soil. The cuttings should be watered moderately and kept in a humid environment, such as under a plastic bag or a misting system. Rooting can take place in about four to six weeks, and the new plants can be transplanted into individual pots.
Division Propagation
Propagation through division involves separating the main plant into smaller sections and planting them in individual pots. Hermannia arabica can be propagated through this method during the spring season. The shrub is carefully dug out of the ground, and the roots are separated into smaller sections, with each section having a good amount of roots attached to it. The new sections are then planted in individual pots in well-draining soil, with well-moistened soil. The plants must be placed in a shaded area to initiate the growth process.
