Light: Sisyrinchium apiculatum Bickn. is a sun-loving plant and grows well in bright to full sunlight. The plant requires at least 6 hours of direct sunlight per day for optimal growth. In shady areas, the growth is limited, and the plant may not produce enough flowers.
Temperature: The ideal growth temperature for Sisyrinchium apiculatum Bickn. ranges from 15°C to 30°C. The plant cannot tolerate freezing temperatures, and frost may damage the leaves. Therefore, it is best to grow the plant in regions with moderate temperature conditions.
Soil: The plant prefers well-drained soils with neutral pH levels ranging from 6.5 to 7.5. The soil must be rich in organic matter, and the plant is sensitive to soil salinity. Sisyrinchium apiculatum Bickn. can tolerate dry soil conditions but does not thrive in waterlogged soils.
Water: Sisyrinchium apiculatum Bickn. is a drought-tolerant plant and does not require frequent watering. The plant can survive in areas with low rainfall. However, for optimal growth, it is recommended to keep the soil moist during the growing season.
Fertilizer: The plant does not require heavy fertilization, but regular feeding can promote blooming. Use a balanced fertilizer with a ratio of 10-10-10, and apply it once a month during the growing season. Avoid over-fertilizing the plant, as it may damage the roots.
Propagation: The plant can be propagated by seeds or division of mature plants. Plant the seeds directly in the soil during spring, or indoors during winter. Division of mature plants should be done during the dormant season. Plant the newly divided plants in well-drained soil and water thoroughly.
Cultivation Methods
The Sisyrinchium apiculatum Bickn., commonly known as blue-eyed grass, is a perennial plant that thrives in sandy or well-draining soil. It is important to ensure the soil is well-draining because this plant does not do well in overly wet soils. When planting, ensure that the planting hole is slightly wider than the root ball to avoid damaging the roots. Plant the blue-eyed grass in a location with bright and direct sunlight since it requires a minimum of six hours of direct sunlight daily for optimal growth.
Watering Needs
Typically, watering needs for the blue-eyed grass are low, so it survives well in drought conditions. However, adequate moisture is still necessary to achieve optimal growth and attractive blooms. Water the plant only when the soil gets dry to about 1-2 inches deep. When watering, consider watering the roots and not the foliage to avoid fungal diseases.
Fertilization
Fertilizing is not necessary for the blue-eyed grass. However, you can provide a small amount of balanced fertilizer to improve the plant's growth and add to its longevity if necessary. It's advisable to apply the fertilizer early in spring when the plant is actively growing and using energy optimally. Use a balanced 10-10-10 fertilizer at a rate of one pound per 100 square feet.
Pruning
Pruning the blue-eyed grass is straightforward and requires you to trim the foliage to a few inches above the ground level after flowering. This encourages new growth, and it takes the plant one season to regain its attractiveness. For an optimal lifespan, prune the plant every year after flowering to achieve the desired lush growth the following season.
Propagation of Sisyrinchium apiculatum Bickn.
Sisyrinchium apiculatum Bickn. can be propagated by seeds or division.
Propagation by Seeds
The seeds of Sisyrinchium apiculatum Bickn. should be sown in well-draining soil during the spring. It is recommended to soak the seeds in water for a few hours before planting to increase the germination rate. After sowing the seeds, cover them lightly with soil and keep the soil moist. The seeds will germinate in two to four weeks. Once the seedlings are large enough to handle, they can be transplanted to their permanent location.
Propagation by Division
Division is the easiest and most common method of propagating Sisyrinchium apiculatum Bickn. This method should be performed during the plant's dormant season, which is typically in the fall. Carefully dig up the plant and use a clean, sharp knife to divide the rhizomes into sections. Each section should have at least one shoot and a portion of the root system. Replant the divisions in their permanent location and water them well.
