Gerbera Daisies: Complete Growing & Care Guide

Introduction to Gerbera Daisies

Gerbera daisies (Gerbera jamesonii) stand out as some of the most vibrant and cheerful flowers you can grow in your garden or containers. Native to South Africa, these beautiful members of the Asteraceae family bring a splash of color and joy with their daisy-like blooms that come in almost every color of the rainbow. Their popularity extends beyond garden beds—gerberas rank among the world’s most beloved cut flowers, prized for their long-lasting blooms and striking appearance.

These eye-catching flowers feature large, solitary blooms perched atop leafless stems that rise elegantly above rosettes of dark green, slightly fuzzy foliage. The flowers themselves showcase a remarkable variety of colors including vibrant reds, sunny yellows, delicate pinks, pure whites, rich oranges, and even purples—often with contrasting centers that add to their visual appeal.

Gerbera Daisy Basics

Botanical Information

Gerbera daisies belong to the same family as sunflowers, marigolds, and other daisies. The genus name Gerbera honors Traugott Gerber, an 18th-century German naturalist. These plants are also known by several common names including African daisy, Transvaal daisy, and Barberton daisy—all referencing their South African origins.

While there are numerous species within the Gerbera genus, most garden varieties are derived from Gerbera jamesonii or hybrids. Through careful breeding, horticulturists have developed an impressive array of cultivars offering different colors, flower forms, and sizes to suit various garden needs.

Growing Zones and Conditions

Gerbera daisies thrive as perennials in USDA Hardiness Zones 8-11, where the climate mimics their native South African habitat. In these warmer regions, they can return year after year, growing more robust with proper care. For gardeners in colder climates (Zones 7 and below), these beautiful flowers are typically grown as annuals or potted plants that can be brought indoors during winter months.

When grown as perennials, gerbera plants can reach up to 18 inches in height and width, with flower stems potentially extending up to 3 feet tall in optimal conditions. As annuals in cooler regions, they generally stay more compact, typically reaching about 12 inches in height.

Gerbera Daisy Varieties

Modern breeding has resulted in an impressive diversity of gerbera daisy varieties, categorized primarily by their flower structure. Understanding these different types can help you select the perfect gerberas for your garden or floral arrangements.

Single Flower Gerberas

Single flower varieties represent the most common and traditional form of gerbera daisies. They feature a single row of non-overlapping petals (ray florets) surrounding a prominent center disk. These classic beauties showcase the natural charm of the species and are often favored for their simplicity and elegance.

Semi-Double Flower Gerberas

Semi-double gerberas display two to three rows of petals, creating a fuller appearance while still maintaining a visible center disk. These varieties offer more visual density than singles without the complete fullness of double types, striking a pleasing middle ground that works well in both gardens and arrangements.

Double Flower Gerberas

Double-flowered varieties exhibit multiple layers of petals, giving them a luxurious, almost rose-like appearance. This category includes several subtypes:

• Standard doubles with overlapping rows of petals
• Crested doubles featuring distinctive central formations
• Fully-crested varieties where inner petals completely cover the central disk

Specific cultivars like ‘Terracotta’ with its double yellow petals accented by peach tones, and ‘Winter Queens’ with striking white petals surrounding a black eye, exemplify the diversity within this category.

Spider Flower Gerberas

Spider-type gerberas feature unique, thin petals with pointed tips that create a spiky, star-like appearance. These distinctive blooms add textural interest and a contemporary feel to gardens and are particularly valued for their unusual form in cut flower arrangements.

Planting Gerbera Daisies

When to Plant

The ideal planting time for gerbera daisies depends on your climate and whether you’re growing them as annuals or perennials:

• In Zones 8-11: Plant in early spring after the last frost has passed
• In colder regions: Wait until soil temperatures have warmed to at least 65°F, typically mid to late spring
• Container planting: Can be done anytime during the growing season as long as extreme temperatures are avoided

Where to Plant

Location selection plays a crucial role in the success of your gerbera daisies. These flowers thrive in spots that receive plenty of sunlight (at least 6 hours daily) but appreciate some protection from intense afternoon heat, especially in warmer climates. Morning sun with afternoon shade often provides the perfect balance, particularly in hot southern regions.

Good air circulation is essential for preventing fungal issues, so avoid crowding gerberas or planting them in stagnant corners of the garden. They perform beautifully in raised beds, which provide the excellent drainage these plants require. Container growing is also highly successful, offering the flexibility to move plants to optimal positions as seasons change.

Soil Requirements

Soil quality significantly impacts gerbera performance. These plants require well-draining, nutrient-rich soil with a slightly acidic to neutral pH (5.5-6.5). Heavy clay soils can lead to root rot and should be amended with organic matter before planting. Creating the ideal soil environment includes:

• Incorporating plenty of compost or well-rotted manure to improve fertility
• Adding coarse sand or perlite to enhance drainage
• Ensuring the planting area is slightly elevated to prevent water accumulation around the crown

When planting, position gerberas so that their crown (where the stem meets the roots) sits slightly above soil level to prevent rotting. Space plants 12-18 inches apart to allow proper air circulation and room for growth.

Gerbera Daisy Care

Watering Needs

Proper watering is perhaps the most critical aspect of gerbera daisy care. These plants require consistent moisture but are highly susceptible to crown and root rot if overwatered. The goal is to keep the soil evenly moist but never soggy, with particular attention to keeping water off the crown and foliage.

Water gerberas at the base of the plant, ideally with drip irrigation or a soaker hose, providing approximately 1 inch of water weekly. Allow the top 1-2 inches of soil to dry out between waterings—check by inserting your finger into the soil to gauge moisture levels. During hot periods, you may need to water more frequently, while cooler weather requires less frequent irrigation.

Light and Temperature

Gerbera daisies flourish with 4-6 hours of morning sunlight followed by afternoon shade, especially in hot climates. In cooler northern regions, they can often tolerate full sun throughout the day. These plants prefer moderate temperatures between 65-75°F (18-24°C) for optimal flowering and growth.

Extreme heat (above 85°F/29°C) can stress plants and reduce flowering, while temperatures below 30°F (-1°C) will damage or kill plants unless they’re protected. In marginal zones, applying a thick layer of mulch around plants (but not touching the crown) can help them survive milder winters.

Fertilization

Gerberas are moderate to heavy feeders that benefit from regular fertilization throughout the growing season. Begin feeding plants about two weeks after planting, using a balanced water-soluble fertilizer (10-10-10 or 15-15-15) diluted to half strength every two weeks. Alternatively, apply a slow-release granular fertilizer according to package directions, typically once every 3-4 months.

Excessive nitrogen can produce lush foliage at the expense of flowers, so during the main blooming period, consider switching to a formula higher in phosphorus (such as 5-10-5) to encourage more abundant flowering.

Pruning and Deadheading

Regular deadheading—removing spent blooms—is essential for promoting continued flowering in gerbera daisies. Rather than just snipping off the flower head, trace the stem down to its base near the crown and cut there. This approach prevents stem stubs from rotting and encourages fresh growth from the base.

Periodically removing older, damaged, or diseased leaves helps maintain plant health and appearance. In perennial settings, perform a more substantial cleanup in early spring, removing any winter-damaged foliage to make way for new growth.

Common Problems and Solutions

Pests

Gerbera daisies can attract several common garden pests, each requiring specific management approaches:

• Aphids: These small sap-sucking insects cluster on new growth and flower buds. Control with insecticidal soap, neem oil, or a strong spray of water.
• Spider Mites: Particularly problematic in hot, dry conditions, these tiny pests cause stippling on leaves. Increase humidity around plants and treat with insecticidal soap or horticultural oil.
• Thrips: These slender insects damage flowers and leaves, causing distorted growth. Use blue sticky traps for monitoring and insecticidal soap for control.
• Whiteflies: Small white insects that flutter when plants are disturbed. Yellow sticky traps help reduce populations, while insecticidal soap targets nymphs.

Diseases

Several diseases can affect gerbera daisies, most related to moisture management:

• Powdery Mildew: Appears as white powdery patches on leaves. Improve air circulation and apply fungicides if necessary.
• Crown Rot: Caused by overwatering or poor drainage, resulting in a mushy crown area. Prevention through proper planting depth and watering practices is key.
• Leaf Spot Diseases: Various fungal and bacterial pathogens cause spotted leaves. Remove affected foliage and avoid overhead watering.
• Botrytis (Gray Mold): Affects flowers, especially in humid conditions. Remove infected blooms promptly and ensure good air circulation.

Growing Challenges

Even with proper care, gerbera growers sometimes encounter these common issues:

• Reduced Flowering: Often caused by insufficient light, improper fertilization, or aging plants. Adjust growing conditions and divide older plants when necessary.
• Crown Burial: The crown becoming buried by soil leads to rotting. Carefully remove excess soil to re-expose the crown.
• Leaf Yellowing: May indicate nutrient deficiencies, particularly iron. Consider soil testing and appropriate amendments.
• Short Flower Stems: Usually related to insufficient light or overcrowding. Ensure plants receive adequate sunlight and proper spacing.

Seasonal Care

Spring Care

Spring marks the beginning of active growth for gerbera daisies. In perennial settings, remove any winter mulch gradually as temperatures warm. Divide overcrowded plants every 2-3 years in early spring. For new plantings, wait until soil has warmed and all danger of frost has passed before introducing gerberas to the garden.

Summer Maintenance

During summer, focus on consistent watering and deadheading to encourage continuous blooming. In particularly hot regions, provide afternoon shade to prevent heat stress. Continue regular feeding and monitor closely for pests, which tend to proliferate in warm weather.

Fall Preparation

In perennial zones, prepare gerberas for the cooler months by reducing fertilization about six weeks before the first expected frost. Clean up fallen leaves and debris around plants to prevent disease. In marginal zones, begin considering winter protection strategies.

Winter Protection

In Zones 8-11, gerberas typically require minimal winter protection beyond reducing water during dormancy. In Zone 8 and cooler parts of Zone 9, apply a layer of mulch around plants (not covering the crown) after the first light frost. In Zones 7 and below, consider potting plants to bring indoors, or treat as annuals to be replaced the following spring.

Using Gerbera Daisies in the Garden

Landscape Applications

Gerbera daisies shine in various garden settings:

• Border edges where their colorful blooms can be appreciated up close
• Mass plantings for dramatic color impact
• Mixed perennial beds where they provide reliable summer color
• Cottage gardens where their informal charm fits perfectly

Container Growing

Gerberas excel in container culture, which allows control over soil quality and positioning. Use pots at least 12 inches in diameter with ample drainage holes. A high-quality potting mix specifically formulated for flowering plants provides the ideal growing medium. Container-grown gerberas benefit from being slightly pot-bound, so don’t use oversized containers.

Cut Flowers

Gerbera daisies make exceptional cut flowers, lasting 7-10 days in arrangements. For longest vase life, harvest when flowers are fully open in the morning hours. Cut stems at an angle and place immediately in water. Change vase water every 2-3 days and keep arrangements away from ripening fruit, which releases ethylene gas that shortens flower longevity.

Propagation Methods

While most home gardeners purchase established plants, gerbera daisies can be propagated through division or seeds:

Division

Division is the most reliable method for maintaining specific varieties. In early spring, carefully dig up established plants and gently separate the crown into sections, ensuring each division has roots and leaves attached. Replant divisions immediately at the same depth as the original plant, keeping the crown slightly above soil level.

Seed Starting

Growing gerberas from seed requires patience but allows access to a wider variety of types. Sow seeds on the surface of a sterile seed-starting mix, pressing lightly but not covering, as light assists germination. Maintain temperatures around 70-75°F (21-24°C) and consistent moisture. Germination typically occurs within 1-3 weeks, with plants reaching flowering size in 4-5 months.

Frequently Asked Questions

Q: Why aren’t my gerbera daisies flowering?

A: Insufficient sunlight is the most common cause of poor flowering. Ensure plants receive at least 6 hours of sunlight daily. Other causes include excessive nitrogen fertilizer, buried crowns, or temperatures outside the optimal range of 65-75°F (18-24°C).

Q: How do I keep my gerbera daisies blooming all season?

A: Regular deadheading is essential for continuous blooming. Remove spent flowers by cutting stems at their base. Consistent watering, proper fertilization with a phosphorus-rich formula, and protection from extreme heat also encourage prolonged flowering.

Q: Can I save my gerbera daisies over winter?

A: In Zones 8-11, gerberas will return as perennials with minimal protection. In colder zones, you can dig up plants in fall, pot them, and keep them in a bright location around 45-50°F (7-10°C) with minimal watering until spring. Alternatively, treat them as annuals and replace each spring.

Q: Why are my gerbera daisy leaves turning yellow?

A: Yellowing leaves often indicate overwatering or poor drainage. Ensure soil drains well and allow the top inch to dry between waterings. Nutrient deficiencies, particularly iron chlorosis in alkaline soils, can also cause yellowing. A soil test can help identify specific deficiencies.

Q: How deep should I plant gerbera daisies?

A: Plant gerbera daisies so that the crown (where stems meet roots) sits slightly above soil level. Buried crowns are prone to rotting, while exposed roots lead to drought stress. Finding this balance is crucial for plant health and longevity.
