Gerbera daisies are known for their vibrant, cheerful blooms, making them a popular choice for gardens and floral arrangements. Propagating them allows gardeners to expand their collection, save expenses, and share these flowers. This guide outlines effective methods for multiplying Gerbera daisies at home.
Propagating Gerbera from Seed
Starting Gerbera daisies from seed is a rewarding way to grow these flowers, though it requires patience as plants take several months to flower. Begin this process indoors about 12 to 18 weeks before the last anticipated frost in spring. Fresh seeds are recommended, as their viability decreases over time.
Fill seed trays or small pots with a light, well-draining seed-starting mix. A quality mix provides aeration and moisture retention. Gently press Gerbera seeds onto the surface of the moistened mix, ensuring they are not buried, as they need light to germinate. If a seed still has its “feather” attached, position the seed end pointing down with the feathery part just barely above the soil line.
After sowing, cover the trays with a clear plastic dome or plastic wrap to maintain consistent humidity and warmth. Place the covered trays in a warm location where temperatures remain between 70°F and 75°F. While light is required for germination, direct sunlight should be avoided; instead, aim for bright, indirect light for at least eight hours daily.
Germination occurs within two to four weeks. Once seedlings emerge, remove the plastic cover but continue to keep the soil moist, but not waterlogged. When seedlings develop two sets of true leaves, they are ready to be transplanted into individual 4-inch pots.
Propagating Gerbera by Division
Propagating Gerbera daisies through division is effective for rejuvenating mature plants and preserving specific characteristics. This process is best undertaken in early to mid-spring, just as new growth begins, or during the summer when the plant is actively growing. Healthy, mature Gerbera plants that have developed into clumps with multiple crowns are suitable candidates for division. Dividing mature plants also helps improve air circulation around the plant, which can promote more vigorous flowering.
To divide a plant, dig up the entire clump, keeping the root ball as intact as possible. Gently remove excess soil from the roots to see the individual crowns. Using a sharp, sterilized knife or pruning shears, separate the root ball into sections. Each divided section should have its own healthy roots and at least one crown. Trim any damaged roots or old foliage from the divisions.
Replant the divisions immediately into prepared soil, ensuring that the crown of each plant sits slightly above the soil line, about half an inch. This placement helps prevent crown rot, which can occur if the crown is buried too deeply. Water the newly planted divisions thoroughly after replanting to help them establish.
Post-Propagation Care
After propagating Gerbera daisies, whether from seed or by division, consistent care is important for establishment. Newly planted divisions and transplanted seedlings require thorough watering to settle the soil around their roots. The soil should be kept moist but not waterlogged, as Gerbera daisies are susceptible to root rot.
Young seedlings and newly divided plants should be gradually introduced to brighter light conditions. While seedlings need bright, indirect light, established plants thrive in full to partial sun, with some afternoon shade in hotter climates. Maintaining stable temperatures, between 65°F and 70°F, helps minimize transplant shock and promotes healthy growth. Begin light feeding with a balanced, water-soluble fertilizer once the plants show signs of active new growth.
Tips for Successful Gerbera Propagation
Successful Gerbera propagation benefits from careful attention to detail and environmental control. Always use clean, sterilized tools when dividing plants to prevent the spread of diseases. Similarly, using a sterile potting mix for seed starting helps protect young plants from fungal issues like damping-off.
Patience is important, as both methods require time for establishment and growth. Maintaining consistent environmental conditions, including appropriate light, temperature, and moisture levels, is important for developing healthy plants. Regularly monitor young plants for any signs of pests or diseases, addressing issues promptly to prevent widespread problems. Ensuring adequate air circulation around plants can also help deter fungal infections.
