Propagation of Psoralea latestipulata Shinners var. appressa D.J. Ockendon
Psoralea latestipulata Shinners var. appressa D.J. Ockendon can be propagated through several methods:
Seed Propagation
The easiest method of propagating Psoralea latestipulata Shinners var. appressa D.J. Ockendon is through seed propagation. Seeds can be collected in the fall or winter and sown immediately or stored in a cool, dry place until spring. To improve germination rates, seeds can be soaked in water for 12-24 hours before sowing. Cover the seeds with a thin layer of soil and keep them consistently moist until they germinate, which can take up to several weeks. Once the seedlings have grown to a sufficient size, they can be transplanted to their permanent location.
Cuttings
Psoralea latestipulata Shinners var. appressa D.J. Ockendon can also be propagated through stem cuttings. Take stem cuttings in the spring or summer from the current year's growth. Cuttings should be approximately 4-6 inches long and have at least two nodes. Remove the leaves from the lower half of the cutting and dip the cut end in rooting hormone. Plant the cutting in well-draining soil and keep it moist. Cover the cutting with a plastic bag or humidity dome to retain moisture and improve the chances of rooting. Roots should develop in 2-3 weeks, after which the cutting can be transplanted to its permanent location.
Division
Psoralea latestipulata Shinners var. appressa D.J. Ockendon can also be propagated through division. This method is best done in the spring as new growth begins. Carefully dig up the plant and separate the roots into sections, ensuring that each section has at least one growing point. Replant the sections in well-draining soil and keep them consistently moist until they establish themselves.
Disease Management
