Soil Requirements
Erigeron utahensis Gray var. sparsifolius (Eastw.) Cronq. thrives in well-draining soils that are rich in organic matter. It does best in neutral to slightly acidic soils with a pH of 5.8 to 7.2. Soil texture should be sandy or loamy, as this plant variety is prone to rot in waterlogged soils.
The plant is drought-tolerant and can survive long periods of water deprivation, hence an ideal garden plant in arid regions. Deep and infrequent watering or natural rainfall once a month is sufficient for the plant’s hydration needs. Overwatering or poor drainage can lead to root rot and eventual plant death.
Cultivation Methods
Erigeron utahensis Gray var. sparsifolius (Eastw.) Cronq. is not very difficult to cultivate, and can thrive in a variety of growing conditions. It is a hardy perennial that is native to the western United States, and can be grown in USDA hardiness zones 4 to 8. The plant prefers well-drained soil and a location that receives full sun to partial shade.

Watering Needs
Erigeron utahensis Gray var. sparsifolius (Eastw.) Cronq. is a drought-tolerant plant that does not require a lot of water. The plant can survive long periods of drought, but it should be watered deeply when it is first planted to encourage root growth. After the plant is established, it will only need to be watered during extended dry periods. It is important to not overwater Erigeron utahensis Gray var. sparsifolius, as this can cause root rot or other problems.
Fertilization
Erigeron utahensis Gray var. sparsifolius (Eastw.) Cronq. does not require regular fertilization, but it can benefit from a light application of fertilizer in the spring. A balanced fertilizer, such as a 10-10-10 or 5-10-5, can be used.

Pruning
Erigeron utahensis Gray var. sparsifolius (Eastw.) Cronq. does not require much pruning, but it can benefit from deadheading. Deadheading, or removing spent flowers, can encourage the plant to produce more blooms and extend its blooming period. In addition, pruning can be done in the fall after the plant has finished blooming to remove any dead or damaged foliage. It is important to be careful not to prune too much of the plant, as this can stunt its growth and reduce its overall health.
