Propagation of Polygonatum P. Mill. Plant
Polygonatum P. Mill. plant, also known as Solomon's seal, can be propagated through various methods including division, rhizomes, and seeds.
Division
The most common method of propagating Polygonatum P. Mill. plant is through division. This involves separating the plant into smaller sections and replanting them. The best time to divide the plant is in the fall or early spring when it is not actively growing. Carefully dig up the plant and separate the rhizomes, making sure that each section has at least one healthy shoot and root system. Replant the sections in a suitable location, ensuring that they are spaced at least 18 inches apart.
Rhizomes
Polygonatum P. Mill. plant can also be propagated using its rhizomes. This involves digging up the parent plant and carefully cutting off sections of the rhizomes. Each section should have at least one healthy shoot and root system. Plant the sections immediately, ensuring that they are spaced at least 18 inches apart and the soil is moist.
Seeds
Polygonatum P. Mill. plant can be propagated using its seeds. Collect the mature seeds in the fall and plant them immediately in a suitable location or store them for the winter and plant them in the spring.
