Essential Steps for Gerbera Daisy Care
Plant gerbera daisies in your garden after the danger of the last spring frost has passed. When planting, ensure that the crown of the plant—where the stem meets the roots—remains at or slightly above the soil level. Space plants about 12 to 18 inches apart to allow for adequate air circulation and growth.
Light Requirements for Gerbera Daisies
Gerbera daisies are sun-loving plants that bloom from late spring through fall. To achieve their full blooming potential, they need plenty of sunlight. Ideally, gerbera daisies require full sun exposure to flourish. However, while they love sunlight, they are not fans of intense heat. In regions with extremely hot summers, providing some partial shade during the hottest part of the day can help protect them from stress.
Soil for Healthy Gerbera Daisies
For optimal gerbera daisy care, well-drained and rich soil is crucial. Whether you are planting them directly in the ground or in pots, the soil quality significantly impacts their growth and blooming. Gerbera daisies are vigorous bloomers, which means they require nutrient-rich soil to support their energy-intensive flowering process. Amending your garden soil with compost or using a high-quality potting mix for containers will provide the necessary nutrients.
Watering Gerbera Daisies Properly
Consistent moisture is key to healthy gerbera daisy care. These plants thrive in soil that is consistently moist but well-drained. Overwatering and waterlogged soil can lead to root rot, a common problem with gerberas. When planting gerbera daisies, especially in the ground, ensure the crown is slightly elevated, about 1/2 inch above the soil line, in a well-draining location. This helps prevent water from pooling around the crown and causing rot.
During the warmer months, regular watering is essential. A good rule of thumb is to water gerbera daisies about once a week, or whenever the top inch or two of soil feels dry to the touch. In the colder winter months, reduce watering frequency significantly, watering only about once a month, as the plant’s growth slows down.
Temperature and Humidity Considerations
Gerbera daisies are most comfortable in temperatures ranging from 40°F to 70°F. They are not tolerant of extreme heat or temperatures below 40°F. Ideal temperatures for gerbera daisies are mild, between 65°F and 70°F. If you live in an area with hot summers, consider planting your gerberas in a location that receives partial shade, particularly during the hottest afternoon hours, to shield them from heat stress.
In terms of hardiness zones, gerbera daisies are considered hardy perennials in USDA hardiness zones 8 to 10. In these warmer zones, they can survive outdoors year-round. However, in zones below 8, gerbera daisies are typically treated as annuals or grown in containers and brought indoors to overwinter.
Fertilizing Gerbera Daisies for Best Blooms
Fertilizing is an important aspect of gerbera daisy care, especially to encourage abundant blooming. As the weather warms up in spring, begin fertilizing your gerbera daisies to support their active growth phase. Applying organic compost around the base of the plants is a great way to provide a slow-release source of nutrients.
During the summer blooming season, feed your gerbera daisies monthly. Continue to use organic compost or a balanced liquid fertilizer diluted to half strength. This regular feeding will provide the necessary nutrients for continuous blooming. If your gerbera daisies become very bushy, you may need to thin out some of the dense center leaves to improve light penetration and air circulation within the plant, which can further promote healthy growth and flowering.
Exploring Types of Gerbera Daisies
Gerbera daisies are known for their impressive size and diverse forms, setting them apart from traditional daisies. Each gerbera plant can grow up to 18 inches wide and reach heights between 6 to 18 inches. The central disk of the flower exhibits a color spectrum from yellow to green, bronze, and even black, adding to their visual appeal.
The structure of gerbera daisies is also noteworthy. They feature tall, slender stalks with deep green leaves that are elegantly spread out on the stems, positioned much lower than the flower itself. This arrangement enhances the flower’s elegance. The leaves are robust, deeply notched, and lobed, providing a textural contrast to the smooth petals.
Gerbera daisies are classified into different petal profiles, including:
- Single Gerbera Daisies: These classic blooms have a single row of petals that gracefully overlap around the central disc.
- Double Gerbera Daisies: Double daisies feature multiple rows of overlapping petals, creating a fuller, more lush appearance.
- Crested Double Gerbera Daisies: These are similar to double daisies but have an additional ring of smaller petals located just outside the central disc, adding a unique crested effect.
- Spider Gerbera Daisies: Spider daisies are distinguished by their narrow, pointed petals that give them a spidery or quill-like appearance.
The color palette of gerbera daisies is extensive, ranging from warm pinks, reds, oranges, and yellows to purples and classic white with a striking black center. With such a wide variety available, choosing gerbera daisies often comes down to personal preference in color and petal style, as well as what is locally available.
Pruning and Deadheading Gerbera Daisies
Regular pruning and deadheading are essential components of gerbera daisy care. Deadheading, which involves removing spent or wilting blooms, encourages the plant to produce more flowers and extends the blooming period. When blooms start to fade, follow the flower stalk down to the base of the plant and carefully cut the stalk at the crown. This directs the plant’s energy towards new bloom production rather than seed development.
In addition to deadheading, you can also prune leaves from the base of the plant to improve its shape, increase airflow, and allow more sunlight to reach the center. Removing any leaves that are faded, damaged, or unsightly will also enhance the overall appearance of your gerbera daisy plant.
Growing Gerbera Daisies from Seed
Growing gerbera daisies from seed is a rewarding process, although it requires patience as it can take up to six months for seedlings to bloom. To start gerbera daisies from seed, begin by determining the last frost date in your area. Count back 10 to 12 weeks from this date, as this is the ideal time to start your seeds indoors, giving them a head start before spring planting.
Follow these steps to grow gerbera daisies from seed:
- Fill a seed tray with a sterile potting mix and moisten it thoroughly.
- Scatter the gerbera daisy seeds across the surface of the soil and gently press them into the soil. Gerbera daisy seeds require light to germinate, so avoid burying them too deeply.
- Cover the seed tray with plastic wrap or a clear plastic lid to help maintain humidity.
- Place the tray in a warm, sunny location where the temperature is consistently around 70°F. Germination typically occurs within 10 to 28 days.
- Once the last frost date has passed and seedlings are sturdy enough, gradually acclimate them to outdoor conditions (hardening off) before transplanting them into your garden or containers.
Overwintering Gerbera Daisies
The approach to overwintering gerbera daisies depends on your climate. In warmer, southern climates (USDA zones 8-10), gerbera daisies can often remain in the ground over winter. To protect them, apply a layer of mulch around the base of the plants to insulate the roots from cold temperatures.
However, in colder climates, gerbera daisies are not winter-hardy and need to be protected from freezing temperatures. In these regions, it’s best to dig up your gerbera daisies in the fall before the first frost. Pot them in containers and bring them indoors to a cool, bright location for the winter. Reduce watering significantly during the winter months, just enough to keep the soil from completely drying out.

Repotting Container Gerbera Daisies
Gerbera daisies grown in containers typically need repotting every one to two years. Repotting becomes necessary when the roots have filled the container and start to become crowded. The best time to repot gerbera daisies is in early spring, before the start of their active growing season.
When repotting, choose a pot that is only one size larger than the current container. Using a pot that is too large can lead to excess soil moisture, increasing the risk of root rot. Follow these steps for repotting gerbera daisies:
- Begin by placing a 2 to 3-inch layer of fresh potting mix in the bottom of the new pot. Use a potting mix formulated for flowering houseplants for best results.
- Gently remove the gerbera daisy from its current pot. Examine the roots and carefully brush away any loose soil to get a better view.
- Inspect the roots for any signs of disease or rot. If you find any damaged roots, use clean, disinfected pruning shears to carefully trim them away.
- Place the plant in the center of the new pot, on top of the fresh soil layer. Fill in around the sides of the root ball with more potting mix, leaving about 1 inch of space between the soil surface and the rim of the pot.
- Water the newly repotted gerbera daisy thoroughly until water drains out of the bottom of the pot. The plant may wilt slightly initially due to transplant shock, but it should recover within a week or two with proper care.
Harvesting Gerbera Daisies for Bouquets
If you wish to enjoy your home-grown gerbera daisies in bouquets, harvesting them at the right stage is important. Cut the flowers using clean, sharp shears at a 45-degree angle when the buds have fully opened. Harvest in the early morning or late evening when the plants are less stressed.
To prevent drooping, handle cut gerbera daisies carefully and keep them upright immediately after cutting. Gerbera daisy stems can sometimes bend or droop once placed in water, so ensure they are supported upright from the start. Avoid laying them down, even for short periods, after cutting.
Common Pests and Diseases Affecting Gerbera Daisies
Like many garden plants, gerbera daisies can be susceptible to certain pests and diseases. Common pests include aphids, mites, leafminers, and thrips, which can damage leaves and flowers. Regularly inspect your plants for signs of infestation. If pests are present, treat the plants with a narrow-range horticultural oil or insecticidal soap, following product instructions carefully.
One of the main challenges in gerbera daisy care is managing watering properly to prevent diseases. While they need regular watering, especially in hot weather, gerberas are prone to root rot and powdery mildew if the soil stays too damp. Water deeply once a week, preferably in the morning, allowing the foliage and soil surface to dry out during the day. Ensure good air circulation around the plants to help prevent fungal diseases. Allow the soil to dry out slightly between waterings to avoid root rot and powdery mildew issues.
