How to Grow and Care for the Margarita Plant

The “Margarita Plant,” a popular cultivar of the Shasta Daisy (Leucanthemum x superbum ‘Margarita’), brings a cheerful and classic aesthetic to any garden space. Gardeners appreciate its bright, daisy-like flowers and relatively straightforward care requirements. This perennial offers a timeless appeal, adding a touch of simplicity and vibrancy to various landscape designs.

What is a Margarita Plant

The Margarita Plant, botanically known as Leucanthemum x superbum ‘Margarita’, is a Shasta Daisy cultivar. This plant features large, single white petals that radiate outwards from a prominent yellow central disc, creating a familiar daisy appearance. Flowers typically measure 2 to 4 inches in diameter. The plant forms an upright, bushy mound, generally reaching a mature height and spread of 2 to 3 feet. Its dark green foliage provides a dense backdrop for the abundant blooms.

Shasta Daisies, including the ‘Margarita’ cultivar, offer a prolonged flowering season, typically blooming from early summer through early autumn. This extended display makes them a favored choice for continuous color in beds and borders. The plant’s robust nature and classic floral form contribute to its widespread appeal, integrating well into various garden styles.

Planting Margarita Plants

Successful establishment of Margarita Plants begins with proper site selection and soil preparation. These plants thrive in locations that receive full sun exposure, at least six hours of direct sunlight daily for abundant flowering. While they can tolerate some partial shade, especially in hotter climates, brighter conditions optimize bloom production.

They prefer fertile, well-draining soil with a neutral to slightly acidic pH (6.0-8.0). Improve heavy clay soils with organic matter like compost to enhance drainage and provide nutrients. Plant in spring after the last frost, or in fall, allowing roots to establish before extreme temperatures.

When planting, dig a hole twice as wide as the root ball and the same depth, then gently loosen the roots before placing the plant, ensuring the top of the root ball is level with the surrounding soil. Space plants 18 to 24 inches apart for mature growth and air circulation. After planting, water thoroughly to settle soil around the roots.

Caring for Margarita Plants

Water Margarita Plants consistently, especially during dry periods or when newly established. While mature plants can show some drought tolerance, they generally benefit from about an inch of water per week. Check the soil moisture by inserting a finger 1 to 2 inches deep; water if dry. Overwatering should be avoided, as soggy conditions can lead to root issues.

Fertilization is not always necessary if the soil is already rich in organic matter. If soil lacks nutrients or for enhanced blooming, apply a balanced, all-purpose liquid fertilizer (e.g., 10-10-10 NPK) every 4 to 6 weeks during summer. Applying too much fertilizer can sometimes result in more leafy growth at the expense of flowers.

Deadheading spent flowers is a simple yet effective technique to encourage continuous blooming throughout the season. This practice directs the plant’s energy into producing new blossoms rather than setting seeds. Regular deadheading also helps maintain a tidy appearance. While Margarita Plants do not require extensive pruning for shape, cutting back dead or weak stems in late winter or early spring helps rejuvenate the plant and promotes healthy new growth.

Common Problems

Margarita Plants are generally resilient, but can encounter common garden issues. Pests like aphids and spider mites may appear, feeding on plant sap. Symptoms include distorted new growth or tiny webs on the undersides of leaves. A strong water spray can often dislodge aphids, while neem oil or insecticidal soap can manage more persistent infestations. Slugs can also be a nuisance, especially in moist conditions, chewing holes in foliage.

Powdery mildew may manifest as a white, powdery coating on leaves, particularly in humid conditions with poor air circulation. Proper plant spacing helps mitigate this issue. Root rot, characterized by wilting and yellowing leaves despite adequate watering, results from overwatering or poorly draining soil. Improving soil drainage and adjusting watering practices are primary solutions for root rot. Yellowing leaves can also indicate nutrient deficiencies, addressed with appropriate fertilization.

Winterizing Margarita Plants

Margarita Plants are hardy perennials in USDA Zones 5 through 9; preparing them for winter helps ensure their return in subsequent growing seasons. Within their hardiness range, minimal winter preparation is typically needed. After the first hard frost, when foliage begins to die back, cut down the dead growth to the ground.

Applying a layer of organic mulch, such as straw or shredded leaves, around the base of the plant provides additional insulation for the roots in colder regions. This mulch helps protect the plant from extreme temperature fluctuations. For container-grown Margarita Plants, especially in colder climates, move pots to a sheltered, unheated location (e.g., cool garage or shed) where temperatures remain above freezing but below 10°C (50°F). This protects roots from freezing solid, which is more likely in pots than in the ground.
