How to Grow the Beautiful Gerbera Daisies

Gerbera daisies are known for their vibrant colors and large, striking blooms, so much so that they often look too perfect to be real.

A member of the Asteraceae family, which includes sunflowers, Gerbera daisies are native to South Africa but have become popular worldwide due to hybridization, which produces the beautiful, large-petaled flowers seen in gardens and bouquets today.

These daisies are perfect for adding color to containers, garden beds, or as cut flowers, but they do require some specific care, especially when grown outside their native climate.

Growing Gerbera Daisies

Gerbera daisies are sold as starter plants that can be transplanted directly into garden beds or containers, though they can also be grown from seed. However, growing from seed takes time, and is best suited for warmer climates as they take several months to mature.

Planting and Germination

To start Gerbera daisies from seed, sow indoors 12-18 weeks before the last frost. Place the seeds in peat or paper pots to avoid disturbing the roots during transplanting.

The seeds need light to germinate, so press them into the soil surface without covering them. Keep the soil moist and place the pots in a warm, sunny spot at 70-75°F. Seedlings can take two to four weeks to germinate.

Transplant them outdoors after the danger of frost has passed, choosing a spot with good drainage and sunlight.

Deadheading and Maintenance

To keep the plant looking fresh, deadhead spent flowers to encourage new blooms. If the plant becomes too dense, remove some central leaves to allow more light and airflow to reach the inner parts.

Light Requirements

Gerbera daisies thrive in full sun to partial shade. In warmer climates, they do best with morning sun and afternoon shade to avoid excessive heat.

In cooler climates, they can handle full sun throughout the day. Avoid planting them near reflective surfaces, such as stone walls, which can intensify heat and stress the plant.

Soil Conditions

Gerberas prefer rich soil with plenty of organic matter. The ideal soil pH is slightly acidic, around 5.5 to 6.5. If the pH is too high, chlorosis (yellow streaks on leaves) can occur.

On the other hand, a low pH can lead to black spots on the leaves. Amend the soil as needed to achieve the right balance for optimal growth.

Watering Needs

Water Gerbera daisies regularly, aiming for about 1 inch of water per week. Allow the soil to dry out slightly between waterings, as overwatering can lead to root rot.

Newly established plants and those growing in hot, dry conditions may need additional watering. If the leaves turn yellow or appear dry and crispy, this could indicate underwatering. Water at the soil level, avoiding the foliage, to prevent disease.

Temperature and Humidity

Gerberas grow best in USDA zones 8-11. They prefer cooler winter temperatures around 45-50°F, combined with strong, bright light.

In colder zones, they are typically grown as annuals or in pots that can be brought indoors. During winter, reduce watering, as the plants are dormant and only need light moisture once a month.

Fertilizing Gerbera Daisies

The amount of fertilizer depends on soil quality. To promote blooms throughout the summer, apply a water-soluble fertilizer monthly or add organic compost around the roots. Over-fertilizing should be avoided, as it can damage the plant.

Popular Gerbera Daisy Varieties

Several popular varieties of Gerbera daisies are available, each offering unique colors and bloom types:

Gerbera jamesonii: The most common variety in North America, available in a wide color range.
Gerber Minis: Smaller versions, often grown from seed, suitable for compact arrangements.
Spider Gerbera: Characterized by bright green leaves and pale yellow flowers, offering a distinct look.
Lalbagh: A vibrant hybrid with variegated red or yellow flowers, known for its showy appearance.

These varieties allow for a range of options, making Gerberas an adaptable addition to any garden style.

Common Pests and Diseases

Gerbera daisies can attract pests such as aphids, whiteflies, spider mites, and thrips. Regularly inspect the leaves for signs of infestation, particularly if the plants are stressed. Small infestations can often be removed with a strong jet of water, while larger issues may require insecticidal soap or neem oil.

Leaf miners may also appear, leaving distinctive trails in the leaves. If this occurs, remove any damaged leaves. Fungal issues like crown and root rot can be a problem if the soil remains too moist, so allow the soil to dry out between waterings.

Landscape Uses

The vibrant colors of Gerbera daisies make them a striking focal point in any landscape. To create balance, pair them with simpler, lighter-colored plants or delicate foliage that allows the bold flowers to stand out. Some excellent companion plants include:

Calibrachoa: Adds contrasting colors with its delicate flowers.
Diascia: Provides a soft, complementary backdrop.
Hakonechloa macra: This yellow-foliaged grass highlights Gerbera’s colors beautifully.
Sage or Lobelia: Blue-toned flowers enhance the bold colors of Gerberas.

Gerberas also work well as a standalone statement in pots or containers, adding a splash of color to patios, porches, or balconies.

Tips for Cutting and Displaying Gerbera Daisies

For bouquets, cut Gerbera daisies when they are fully open but still firm in the center. Use a shallow container with about an inch of water to prolong their life. Too much water can shorten their display time. If the base of the stem begins to discolor, cut the stem at an angle to refresh it.

Final Thoughts

With their vibrant colors and large blooms, Gerbera daisies bring beauty and joy to any garden. While they require specific care, the effort is well worth it for their stunning display.

Whether used in garden beds, containers, or as cut flowers, Gerbera daisies are a versatile choice that brightens up any space with ease.
