Propagation of Thelypteris ×incesta W.H. Wagner
Thelypteris ×incesta W.H. Wagner, also known as Incestuous Marsh Fern, is a hybrid species that belongs to the family Thelypteridaceae. This plant is most commonly propagated through spores, although it can also be propagated through division.
Propagation through spores
The spores of Thelypteris ×incesta W.H. Wagner can be collected from mature fronds that have developed spore cases. These fronds should be harvested in the morning when the spores are dry and easily shaken from the cases. The spores can then be sown onto a moist and sterile growing medium, such as a mix of peat moss and sand. The container with the spores should then be covered with a plastic bag to maintain humidity and placed in a bright location that is out of direct sunlight. After several weeks, the spores will germinate and small green plants, known as prothalli, will emerge from the growing medium. These prothalli can be carefully removed and transplanted into individual pots with a well-draining soil mix to continue their growth.
Propagation through division
In addition to propagation through spores, Thelypteris ×incesta W.H. Wagner can also be propagated through division. This method involves separating the plant into smaller sections that can be individually potted and grown into new plants. To propagate through division, the mature plant should be carefully removed from its container or garden bed and shaken gently to remove excess soil. The roots of the plant can then be separated into smaller sections using a clean and sharp knife or scissors. Each section should have a good portion of roots and several fronds that will help the plant establish itself in its new environment. The divided sections can then be individually potted into well-draining soil mix and watered thoroughly. These new plants should be placed in a bright location with indirect sunlight and kept moist until they have established new roots.
