Cultivation Methods
Erigeron supplex Gray or the Cushion fleabane plant is primarily grown in gardens for its lovely daisy-like flowers and evergreen leaves. However, it is a hardy plant and can grow in various soil and weather conditions. It prefers full sun exposure but can also tolerate partial shade. Cushion Fleabane is tolerant of drought and low fertility soil. Therefore, it does not require frequent watering or fertilization, making it an ideal plant for beginners or those who want low-maintenance plants in their gardens.
Watering Needs
Cushion Fleabane has low to moderate water needs and is tolerant of drought. Therefore, it is best to water the plant only when its soil is dry to the touch. However, young plants need regular watering to establish their roots and survive the initial growth stages. Additionally, it is essential to avoid overwatering the plant as this can cause fungal diseases and root rot. Water from the base and avoid wetting the leaves as this can cause sunburn or mildew.
Fertilization
Erigeron supplex Gray is a low-fertility plant, meaning that it does not require frequent fertilization. Therefore, it is best to fertilize it once or twice a year using a balanced granular or slow-release fertilizer. Alternatively, you can amend the soil with organic compost to provide the necessary nutrients for the plant's growth and health.
Pruning
Cushion Fleabane does not require frequent pruning as it has a natural mounding growth habit. However, to promote bushier and more compact growth, it is best to prune back any leggy growth or dead stems. You can also shear the plant back to one-third its size in late spring or early summer to encourage a second blooming and maintain its tidy appearance.
Propagation of Erigeron supplex Gray
Erigeron supplex Gray, commonly known as Cutleaf Fleabane, is a perennial plant that grows in the United States and northern Mexico. It produces numerous small daisy-like flowers with yellow centers that bloom from late spring to early summer. Erigeron supplex Gray spreads quickly and easily, making it a popular choice among gardeners. There are two primary methods for propagating Erigeron supplex Gray:
Division
The most common propagation method for Erigeron supplex Gray is division. This method involves separating the plant's root ball into smaller sections, each of which has its own set of leaves and roots. The best time to divide Erigeron supplex Gray is in the spring, just as new growth begins to emerge. Dig up the entire plant, then use a sharp knife or shovel to divide the root ball into sections. Make sure each section has at least two or three shoots and a healthy root system. Replant the sections in well-draining soil at the same depth they were previously growing, and water thoroughly.
Seed
Erigeron supplex Gray can also be propagated from seed, although this method takes longer and requires more patience. Collect the seeds in late summer or early fall, after the flowers have faded and the seed heads have begun to dry out. Allow the seed heads to dry completely, then remove the seeds. Sow the seeds in early spring, either indoors or outdoors, in well-draining soil. Cover the seeds with a light layer of soil, then keep the soil moist but not waterlogged. Germination usually takes 10 to 14 days. Once the seedlings have developed their second set of leaves, transplant them to their permanent location in the garden.
