Propagation of Stipa occidentalis Thurb. ex S. Wats. var. minor sensu C.L. Hitchc., non (Vasey) C.L. Hitchc.
Stipa occidentalis Thurb. ex S. Wats. var. minor sensu C.L. Hitchc., non (Vasey) C.L. Hitchc. can be propagated through seed or vegetative means in order to establish new plants. However, the species does not reproduce readily and can be difficult to propagate.
Seed Propagation
The use of seed is the most common method of propagating Stipa occidentalis Thurb. ex S. Wats. var. minor sensu C.L. Hitchc., non (Vasey) C.L. Hitchc. The plants produce seeds that can be collected in the fall when the seed heads are mature. The seeds should be planted in the spring in a well-draining soil mix. The flats containing the seeds should be kept moist and placed in a cold frame or other protected area with filtered sunlight. The seedlings can then be transplanted to their permanent location after they have reached a suitable size. Germination rates can be low, and the seeds may require stratification or scarification before planting to improve germination.
Vegetative Propagation
Stipa occidentalis Thurb. ex S. Wats. var. minor sensu C.L. Hitchc., non (Vasey) C.L. Hitchc. can also be propagated vegetatively through division or root cuttings. Division should be done in the spring, when the plants are actively growing. The plant should be gently lifted from the ground, and the crown should be carefully divided into sections. Each section should have at least one viable shoot and a portion of the root system. The new plants should be planted in a suitable location and kept moist until established. Propagation through root cuttings involves collecting roots from healthy plants and planting them in a well-draining soil mix. The cuttings should be watered lightly, and the flats should be covered with plastic to maintain humidity. The new plants should be kept in a protected area until established.
Disease Management
Stipa occidentalis var. minor sensu C.L. Hitchc. is not known to be highly susceptible to diseases; however, it may be vulnerable to fungal diseases, including rust, smut, and leaf spot. Regular inspection of plant foliage can help detect these diseases at their earliest stages. The following measures can be employed to manage fungal diseases:
- Pruning and removing affected plant parts
- Proper plant spacing to enhance air circulation
- Maintaining dry foliage by avoiding overhead watering
- Applying fungicides with active ingredients such as copper or sulfur
Pest Management
Stipa occidentalis var. minor sensu C.L. Hitchc. may attract a few pests like aphids, spider mites, and grasshoppers. These pests may cause damage to the plant by feeding on its foliage and stems. The following measures can be employed to manage these pest infestations:
- Pruning and removing affected plant parts
- Introducing natural predators such as ladybugs, spiders, and praying mantis
- Using insecticidal soap or horticultural oils to control insect pests
- Using neem oil or insecticides with active ingredients such as pyrethrin to control spider mites
- Employing mechanical barrier methods to prevent grasshoppers from reaching the plant. This can be done through physical barriers such as mesh or row covers or through trapping.
