WaterMexican Daisy should be watered thoroughly, allowing the soil to dry out somewhat between waterings. This plant prefers a moderate level of moisture but does not do well in soggy soil. During the growing season, watering once a week with approximately 16 ounces of water per square foot of soil should be adequate. However, during hot or dry periods, you might need to water more frequently, especially if the plant is in a container. Decrease watering in the winter, when the plant's growth slows down.
LightMexican Daisy thrives best in full sun to partial shade. It should be placed in a spot where it can receive at least 6 hours of direct sunlight each day. While it can tolerate some shade, the amount of flowering may be reduced in less than optimal light conditions. An east- or west-facing location is ideal to provide the bright conditions this plant loves.
TemperatureMexican Daisy can tolerate a wide range of temperatures, but it grows best when daytime temperatures are between 65 and 75 degrees Fahrenheit. It can survive minimum temperatures down to about 20 degrees Fahrenheit, but frost may damage the foliage. Ideal conditions are warm with good airflow, avoiding extreme cold or heat.
PruningPrune Mexican Daisy to maintain its shape and encourage bushier growth. Pruning can be done in early spring or after the main flowering flush has subsided. Cut back the stems by up to one-third to promote new growth and more flowers. Deadheading, or the removal of faded flowers, can be done regularly throughout the blooming season to keep the plant tidy and encourage additional blooms.

Life cycleErigeron karvinskianus, commonly known as Santa Barbara daisy or Mexican fleabane, begins its life cycle when seeds germinate, typically in spring, given adequate moisture and temperature conditions. Once germinated, the seedlings grow rapidly, developing a rosette of leaves and a robust root system. It then sends up flowering stalks which bloom profusely with small daisy-like flowers, predominantly during the warmer months, though in mild climates it may bloom year-round. After pollination, which is largely done by insects, the plant sets seeds that are dispersed by wind, and sometimes by water or animals. These seeds can lie dormant until the next season, or germinate immediately if conditions are favorable. Finally, as a perennial plant, it can also spread via its root system to create larger clumps, living for several years while continuing its cycle of growth, bloom, seed set, and dormancy.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagation for the Mexican fleabane, Erigeron karvinskianus, is through seed. Sowing can occur in spring once the threat of frost has passed. Seeds are lightly scattered over the surface of a well-draining seed starting mix and gently pressed into the surface. It's important not to cover them with soil as they require light for germination. The container should be kept moist and in a warm spot with plenty of light until germination occurs, which typically takes about two to three weeks. Once the seedlings are large enough to handle, they can be transplanted into individual pots or directly into the garden, spacing them approximately 8 inches (20 centimeters) apart to allow for spreading.
