Propagation Methods of Astragalus beckwithii Torr. & Gray var. weiserensis M.E. Jones
Propagation of Astragalus beckwithii Torr. & Gray var. weiserensis M.E. Jones, also known as Weiser milkvetch, can be achieved through both sexual and asexual means.
Sexual Propagation
The preferred method of propagation for Astragalus beckwithii Torr. & Gray var. weiserensis M.E. Jones is via seed. Seeds should be collected in the fall once the seed pods have matured and have begun to dry. The seeds can be stored in a cool and dry location until they are ready to be planted in the following spring. Stratification can be used to increase germination rates, with seeds being moistened and kept in a cold location for several weeks prior to planting.
Asexual Propagation
Astragalus beckwithii Torr. & Gray var. weiserensis M.E. Jones can also be propagated asexually through division. This method involves digging up an established plant and separating the root ball into multiple sections. Each section should have enough roots and foliage to sustain itself. The new plants can be replanted at the same depth as the original plant and watered regularly until they establish.
Overall, both sexual and asexual propagation methods can be successful for producing new plants of Astragalus beckwithii Torr. & Gray var. weiserensis M.E. Jones.
