Marguerite Daisy Plants (Argyranthemums frutescens) is a great flowering plant for the Southwest region. It can tolerate poor soils and will bloom from early spring until late fall. It will surprise you with its fragrance. You can plant them in containers by themselves or mix them in with other colorful plants. Place these daisies in window boxes or in a garden bed.
They are easy-care plants and require little fertilizer but they should be watered every other day during the mid-summer heat. You can deadhead them to encourage new growth and buds.
The most common ones are the light yellow flowers. In regions where there are no freezes, it will come back. However, it is considered an annual in USDA zones.
Marguerite daisies appreciate regular watering, especially during the intense heat of Southwest summers. While they enjoy moisture, they do not like soggy roots, so well-draining soil is important to prevent root problems. Water deeply when the top few inches of soil feel dry, then allow the soil to dry slightly before watering again.
To keep plants healthy and blooming, apply a good all-purpose fertilizer about two to three times during the growing season. Feeding periodically helps maintain strong growth and encourages continuous flowers, especially during long stretches of heat.
Other types of Marguerite daisies.
These plants come in various colors and types. Most are dark to light yellow but they also come in white, light lavender, and pink.
Monrovia wholesale nurseries have some nice-looking hybrid daisies, and you can read more about them at this link: Monrovia.com. It’s important to note that some of these daisies are recommended for USDA zones 10-11 and are not recommended for the extreme hot Southwest weather.
The Daisies pictured below will thrive in and around the Southwest.
When to plant the Marguerite plant?
The best time is in early spring, either by seeds or in pots that can be purchased at your local nursery. It is an excellent plant to attract butterflies and bees.
Problems with these plants.
The plant can develop root rot if the soil does not drain well. Snails are also a big problem. They will chomp on the foliage of the Marguerite Daisy. You can use Sluggo™ to kill these garden pests. Sluggo™ is an organic product and can be purchased at most gardening or nursery stores, including the big box ones. Spider mites and aphids are also a problem. Spray with neem oil to remove these pests.
