- Dispose of the pruned material immediately as it can attract pests and diseases.
Propagation of Navarretia Prolifera Greene
Navarretia prolifera Greene, commonly known as the branching navarretia, is a wildflower native to western North America. It is an annual plant that blooms from spring to early summer and can be easily propagated by several methods.
Seed Propagation
Seed propagation is the most common and easiest way to propagate Navarretia prolifera. The seeds are small and can be collected from mature plants after their blooming period. The collected seeds should be stored in a dry and cool place until they are ready to be sown. Seedlings can be started indoors in trays or directly sown in the ground after the last frost.
Division Propagation
Division propagation can be used for mature Navarretia prolifera plants. The plant can be divided carefully by digging around the root ball. Once dug and lifted, the plant should be carefully divided into several sections, ensuring that each section has healthy roots. Each section should be replanted in well-draining soil and kept moist until it establishes roots. Division propagation should be done during the fall season, after the plant has finished blooming.
Cuttings Propagation
Cuttings propagation can be done by taking stem cuttings from a mature plant in the summer season. Cuttings should be about 4-6 inches long and should be planted in moist soil. Cuttings should be kept in an area that is partially shaded or sheltered from direct sunlight until they establish roots. Once rooted, the cuttings can be transplanted to their final location.
