Pruning
Pruning is an essential aspect of the care of Lupinus diversalpicola C.P. Sm. The plant grows tall and spindly, and if left unpruned, it can appear untidy. It is advisable to prune the plant during the fall or winter months. One should prune the plant down to the base to help create a more compact and neat plant. By pruning, the plant can grow better and develop more vigorous and healthy foliage.
Propagation of Lupinus Diversalpicola C.P. Sm.
Lupinus diversalpicola C.P. Sm., commonly known as Sierra Lupine, is a beautiful perennial plant that is native to the Sierra Nevada mountain range in California. It is a member of the legume family, and it grows up to two feet in height with clusters of purple or blue flowers. It prefers well-drained soil and full sunlight.
There are several methods used to propagate Sierra Lupine.
Propagation by Seed
The most common way to propagate Sierra Lupine is by seed. Collect mature seeds in the fall and lightly cover them with soil and water thoroughly. Germination usually takes place in the spring. This method is the easiest and most reliable if you want to propagate Lupine in large numbers.
Propagation by Cuttings
Another method to propagate Sierra Lupine is by cuttings. Cut 4 to 6 inches branches from a healthy plant using a sharp knife, ensure there is at least one node in each cutting. Plant the cut end in a container filled with moist potting soil. Keep the soil damp and in a cool, shady location until roots appear. Transplant the rooted cutting into a well-drained sunny location.
Propagation by Division
When the plant matures, you can divide its rootball to propagate Sierra Lupine. Dig around the rootball, and gently lift the plant out of the ground. Gently separate the rootball into two or three sections, ensuring you keep all the roots intact. Replant the divided sections and keep them well hydrated until they establish in their new location.
Propagation allows for the regrowth of Sierra Lupine in areas where it is becoming rare or extinct. It is essential to ensure responsible and legal collection and propagating of this plant, which is considered sensitive in some States and Nations.
