- Remove dead or damaged growth - If you notice any dead or damaged stems or leaves, you can carefully prune them back to help the plant focus its energy on healthy growth.
Propagation of Navarretia jaredii Eastw.
Navarretia jaredii Eastw., commonly known as Jared's Pincushion, is a delicate, annual plant that belongs to the Phlox family. It is mainly found in California and is known for its beautiful, pink flowers that bloom in the spring and summer months. If you want to propagate Navarretia jaredii Eastw., you can use a few different methods.
Seed Propagation
The most common method of propagating Navarretia jaredii Eastw. is by seed. You can collect the seeds from the plant as soon as they are ripe. The seeds are small and delicate, so handle them carefully. Once you have collected the seeds, you need to plant them in a well-draining soil mix. Cover the seeds with a thin layer of soil and water them gently. Keep the soil moist and in a warm place until the seeds germinate.
Division
Navarretia jaredii Eastw. can also be propagated by division. This method is best used on established plants that have multiple crowns.
