Rhizome Division
Elytrigia pontica propagates naturally through rhizomes, which can be used for vegetative propagation. In spring or autumn, the rhizomes can be dug up and divided into smaller sections, making sure each section has at least one growing point. The divided rhizomes can then be planted in prepared soil, making sure the growing point is facing upward and covered with soil. It's essential to keep the soil moist during the establishment phase.
Vegetative Propagation
Elytrigia pontica can also be propagated through vegetative means such as stem cuttings or tissue culture. Stem cuttings can be taken in the spring or early summer from the new growth. The cuttings should be around 10 cm in length, with the leaves removed from the lower part of the stem. Insert the cuttings into a rooting hormone and place them in prepared soil. Tissue culture propagation is a more advanced method that requires sterile conditions and specialized equipment.
Overall, Elytrigia pontica (Podp.) Holub, is a hardy plant that can be propagated through various means such as seeds, rhizomes, and vegetative methods. Each method has its advantages and disadvantages, and the propagation method used will depend on the specific purpose and resources available.
