Daisies are cherished garden plants known for their cheerful, classic blooms. Propagating daisies is a rewarding way to expand your garden or share these beautiful flowers. Whether you are looking to fill new garden spaces or rejuvenate existing daisy patches, understanding propagation techniques can help you cultivate a thriving display.
When and Why to Propagate Daisies
The optimal time for propagating daisies is early spring or autumn. For division, early spring, just as new growth emerges, or early fall, after the blooms have faded, are ideal periods. Sowing seeds can be done in early winter through late spring, or in the fall.
Propagation offers several advantages. It increases plant numbers, expanding displays without new purchases. Division rejuvenates overgrown clumps, promoting vigorous growth and abundant blooms. It also improves air circulation, mitigating fungal issues. Propagation also allows sharing plants and cost-effectively filling garden beds.
Propagating Daisies by Division
Dividing mature daisy clumps is an effective method. This process is typically undertaken every three to five years to maintain plant health and flowering performance. Begin by cutting back the daisy stems to about 6 inches from the ground.
Next, use a sharp spade or garden fork to carefully dig around the perimeter of the daisy clump, approximately 4 to 6 inches away from the main stems. Dig deeply to ensure you get as much of the root ball as possible. Once loosened, gently lift the entire clump from the soil. Shake off excess soil to expose the root system.
With the root ball exposed, gently tease apart the clump into smaller sections, ensuring each division has a healthy amount of roots and several stems. For dense or intertwined roots, a sharp knife or spade can be used to make clean cuts. Discard any woody, dead, or unproductive portions from the center of the original clump.
Prepare new planting holes that are slightly larger than the root balls of your divisions, incorporating compost or well-rotted manure to enrich the soil. Plant each division so its crown, where the foliage meets the roots, is level with the soil surface. Gently firm the soil around the new plants and water thoroughly to settle the soil and eliminate air pockets.
Propagating Daisies from Seed
Growing daisies from seed is a straightforward method, though it often takes longer to achieve flowering plants compared to division. Daisy seeds can be started indoors or direct-sown outdoors, depending on your climate and desired timing. For indoor sowing, begin 6 to 8 weeks before the last expected frost. Fill seed trays or small pots with a well-draining seed-starting mix, then moisten the soil thoroughly.
Scatter the daisy seeds lightly on the soil surface, as they require light for germination; avoid burying them deeply. A very thin layer, about 1/8 inch, of soil can be used to lightly cover them. Gently press the seeds into the mix to ensure good seed-to-soil contact. Maintain consistent moisture in the soil using a fine mist or gentle watering, but avoid overwatering. Daisy seeds typically germinate within 10 to 20 days when kept at a temperature around 70 degrees Fahrenheit.
If starting indoors, provide plenty of light from a sunny windowsill or grow lights once seedlings emerge. Before transplanting outdoors, gradually acclimate the seedlings to outdoor conditions, a process known as hardening off. For direct sowing, wait until after the last frost and when the soil temperature reaches at least 60-70 degrees Fahrenheit. Select a sunny location with well-draining soil, prepare the bed by loosening the soil, and sow seeds as described.
Caring for Your New Daisy Plants
Proper care ensures newly propagated daisy plants establish well and thrive. Consistent moisture is important during initial establishment. Water the plants at their base, providing about 1 to 2 inches of water per week, especially during dry spells. Daisies prefer well-draining soil and do not tolerate soggy conditions, which can lead to root issues.
Ensure your new daisy plants receive ample sunlight, ideally a location with full sun exposure for at least six hours daily, as this promotes robust growth and abundant blooms. While newly transplanted seedlings or divisions are establishing, protecting them from strong winds can prevent damage. A light layer of mulch around the base of the plants can help conserve soil moisture, regulate soil temperature, and suppress weeds.
As the plants grow, occasional feeding with a balanced, all-purpose fertilizer can support healthy development. Young daisy plants grown from seed may not flower in their first year, focusing instead on establishing a strong root system. However, with proper care, they will typically produce blooms in their second growing season.
