Growing daisy flowers is a rewarding endeavor for gardeners of all skill levels. Daisies, with their cheerful appearance and vibrant colors, can brighten any garden and are relatively easy to cultivate. This comprehensive guide will cover everything you need to know about growing daisy flowers, from choosing the right varieties to planting, caring, and troubleshooting common issues.
Understanding Daisy Flowers
Daisies belong to the Asteraceae family, which includes a wide variety of flowering plants. The most common types of daisies include the classic Shasta Daisy (Leucanthemum × superbum), the cheerful Gerbera Daisy (Gerbera jamesonii), and the delicate English Daisy (Bellis perennis). Understanding the specific needs of the type of daisy you wish to grow is crucial for successful cultivation.
Choosing the Right Daisy Variety
1. Shasta Daisy
Shasta daisies are perennial flowers known for their white petals and yellow centers. They can grow up to 3 feet tall and bloom from early summer to early fall. Shasta daisies are hardy in USDA zones 5-9 and prefer full sun.
2. Gerbera Daisy
Gerbera daisies are popular for their bright and varied colors, including red, yellow, pink, and orange. They are often grown as annuals in colder climates (USDA zones 8-11) and perennials in warmer regions. They require well-drained soil and full sun to partial shade.
3. English Daisy
English daisies are smaller than Shasta and Gerbera daisies, typically growing to about 6 inches tall. They are often used as ground cover or in rock gardens. These daisies prefer cooler climates and are hardy in USDA zones 4-8.
Preparing the Soil
1. Soil Type
Daisies are not particularly fussy about soil type, but they thrive best in well-drained, moderately fertile soil. Sandy loam or loamy soil is ideal. If your soil is heavy clay, consider amending it with organic matter like compost to improve drainage.
2. Soil pH
Most daisy varieties prefer a slightly acidic to neutral pH range, between 6.0 and 7.0. You can test your soil pH using a home testing kit or by sending a sample to a local extension service.
Planting Daisy Flowers
1. When to Plant
The best time to plant daisies depends on your climate and the type of daisy you are growing. In general, it’s best to plant perennials like Shasta daisies in early spring or early fall, giving them time to establish roots before the heat of summer or the cold of winter. Annuals like Gerbera daisies can be planted in spring after the last frost.
2. How to Plant
Site Selection: Choose a location that receives at least 6 hours of sunlight per day. Ensure the soil is well-drained to prevent root rot.
Spacing: Space daisy plants about 12-18 inches apart to allow for air circulation and growth.
Planting Depth: Dig a hole twice as wide as the root ball and of equal depth. Place the plant in the hole, ensuring that the crown (where the stem meets the roots) is level with the soil surface.
Watering: Water thoroughly after planting to settle the soil around the roots.
Caring for Daisy Flowers
1. Watering
Daisies need consistent moisture, especially during their first growing season. Water deeply once a week, ensuring the soil is moist but not waterlogged. In hot, dry conditions, you may need to water more frequently.
2. Fertilizing
Daisies benefit from a balanced, slow-release fertilizer applied in the spring as new growth begins. Avoid high-nitrogen fertilizers, which can promote excessive leaf growth at the expense of flowers. A 10-10-10 or 5-10-5 fertilizer is ideal.
3. Mulching
Mulching helps retain soil moisture, suppress weeds, and regulate soil temperature. Apply a 2-3 inch layer of organic mulch, such as shredded bark or straw, around the base of the plants. Be sure to keep the mulch a few inches away from the stems to prevent rot.
4. Pruning and Deadheading
Regular deadheading (removing spent flowers) encourages continuous blooming and prevents the plant from using energy to produce seeds. In late fall, after the first frost, cut back the stems of perennial daisies to about 2 inches above the ground. This helps prepare the plant for winter dormancy and promotes vigorous growth in the spring.
Common Pests and Diseases
1. Pests
Aphids: Small, sap-sucking insects that can cause distorted growth. Control them with insecticidal soap or by introducing beneficial insects like ladybugs.
Slugs and Snails: These pests can chew holes in leaves and flowers. Use slug bait, copper barriers, or hand-pick them off plants.
Spider Mites: Tiny pests that can cause yellowing and stippling on leaves. Spray with water or use miticides if infestations are severe.
2. Diseases
Powdery Mildew: A fungal disease that appears as a white, powdery coating on leaves. Ensure good air circulation, avoid overhead watering, and use fungicides if necessary.
Leaf Spot: Brown or black spots on leaves caused by fungal or bacterial pathogens. Remove and destroy infected leaves, and apply appropriate fungicides.
Root Rot: Caused by overly wet soil. Ensure proper drainage and avoid overwatering.

Propagating Daisy Flowers
1. From Seeds
Growing daisies from seeds is a cost-effective method, especially for annual varieties like Gerbera daisies. Here’s how to do it:
Seed Starting: Start seeds indoors 6-8 weeks before the last frost date. Sow seeds in seed-starting mix, lightly covering them with soil.
Germination: Keep the soil moist and provide light by placing the trays under grow lights or in a sunny window. Seeds typically germinate in 10-14 days.
Transplanting: Once seedlings have two sets of true leaves and the danger of frost has passed, harden them off by gradually exposing them to outdoor conditions before planting in the garden.
2. From Cuttings
Propagation from cuttings is commonly used for perennial daisies like Shasta daisies:
Taking Cuttings: In late spring or early summer, cut a 4-6 inch stem from a healthy plant, just below a leaf node.
Rooting: Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a pot filled with moist potting mix, and cover with a plastic bag to retain humidity.
Transplanting: Once roots have developed (in about 4-6 weeks), transplant the cutting to the garden.
3. Division
Division is an effective way to propagate and rejuvenate established clumps of perennial daisies:
Timing: Divide daisies in early spring or early fall when the weather is cool.
Digging Up: Dig up the entire clump and gently separate it into smaller sections, each with a portion of the root system and foliage.
Replanting: Replant the divisions immediately, spacing them appropriately and watering well.
Designing with Daisies in the Garden
1. Garden Beds and Borders
Daisies are versatile and can be used in various garden settings. Plant them in mixed borders, combining with other perennials like coneflowers, black-eyed Susans, and lavender for a vibrant display.
2. Containers
Gerbera daisies, with their compact growth habit and striking blooms, are perfect for container gardening. Use a well-draining potting mix and ensure the container has drainage holes. Position the container in a sunny spot and water regularly.
3. Meadow Gardens
For a naturalistic look, consider planting English daisies in a meadow or wildflower garden. They pair well with grasses and other wildflowers, creating a charming, informal display.
Conclusion
Growing daisy flowers can be a delightful and fulfilling gardening experience. By choosing the right variety, preparing the soil, planting correctly, and providing consistent care, you can enjoy a vibrant display of daisies in your garden year after year. Whether you are a novice gardener or an experienced horticulturist, daisies are a wonderful addition to any landscape, offering beauty and cheerfulness throughout the growing season.
