Dahlinova dahlias are a popular series of compact dahlia varieties, celebrated for their vibrant, continuous blooms and manageable size. Their prolific flowering and adaptability make them a favored choice for various garden designs, from container arrangements to border plantings. These dahlias are recognized for their ease of care, appealing to both novice and experienced gardeners seeking reliable floral displays.
Dahlinova Distinctive Features
Dahlinova dahlias are characterized by a naturally compact growth habit, typically reaching 8 to 18 inches tall and spreading 10 to 14 inches. This smaller stature makes them well-suited for container gardening, window boxes, and the front of garden borders. Their uniform mounding habit and excellent branching contribute to a full, bushy appearance.
These dahlias are known for their early and continuous blooming, often flowering from late spring through autumn, providing extended periods of color. The blooms are often double, featuring a wide spectrum of vibrant colors and bicolors, including shades of pink, red, and white. Dahlinova dahlias are also noted for their good branching and consistent flowering, producing abundant blossoms that are excellent for cutting. They also exhibit heat tolerance and resistance to some common issues like powdery mildew.
Planting Dahlinova Dahlias
Planting Dahlinova dahlias begins with selecting an appropriate site. These plants thrive in full sun, ideally at least six to eight hours of direct sunlight daily. While they can tolerate some partial shade, too little light can reduce bloom production. Protection from strong winds is beneficial, so a sheltered spot or planting near a fence is advantageous.
Dahlinova dahlias prefer fertile, moist, and well-draining soil, as they are susceptible to rot in waterlogged conditions. Incorporating organic matter, such as well-rotted manure or compost, can improve soil structure and fertility. If planting in containers, ensure the pots have drainage holes and use a quality, well-draining potting mix.
Plant tubers in the spring after the last frost has passed and the soil temperature has warmed to at least 60°F (15.5°C). Tubers should be planted with the ‘eye’ or crown facing upwards, 4 to 6 inches deep. Space smaller varieties at least 12 inches apart, while larger types may need up to 20 inches to 3 feet of spacing for adequate air circulation. After planting, initial watering should be minimal; avoid watering again until green sprouts emerge from the soil.
Essential Dahlinova Care
Once Dahlinova dahlias sprout, consistent watering is important, especially for container-grown plants which may need daily watering. For garden beds, water deeply two to three times per week, allowing the top inch or two of soil to dry slightly between waterings to prevent root rot. During hot, dry periods, increased frequency may be necessary.
Fertilization supports continuous blooming throughout the growing season. After sprouting, apply a low-nitrogen, balanced liquid fertilizer, such as a 5-10-10 or 10-20-20 blend, every two to four weeks. Avoid high-nitrogen fertilizers, as these can promote leafy growth at the expense of flowers. Prompt deadheading, which involves removing spent blooms, encourages the plant to produce more flowers rather than setting seed.
Pinching the central stem when the plant is about a foot tall encourages bushier growth and more blooms. In colder climates (USDA Zones 8 or cooler), Dahlinova dahlia tubers need to be lifted after the first hard frost and stored indoors over winter to protect them from freezing temperatures. Clean the tubers, allow them to dry for a few days, and then store them in a cool, dry place in slightly moist peat moss or sand.
Addressing Common Dahlinova Problems
A common concern for Dahlinova dahlias is a lack of blooms. This often results from insufficient sunlight, as dahlias require at least six hours of direct sun daily for optimal flowering. Over-fertilizing with high-nitrogen products can also lead to abundant foliage but few flowers. Ensuring proper watering and adequate spacing can also support bloom production.
Dahlias can attract various pests, including aphids, thrips, and spider mites, which feed on plant sap. A strong spray of water can dislodge aphids, while insecticidal soap or neem oil can help manage infestations. Slugs and snails may also cause damage, particularly to young plants and leaves, and can be managed by hand-picking or using organic baits.
Fungal diseases, such as powdery mildew, can appear as a white, powdery coating on leaves, especially in humid conditions. Good air circulation, achieved through proper spacing, helps prevent this issue. Crown rot, often indicated by wilting and yellowing leaves, is usually a result of overly wet, poorly drained soil. Ensuring well-draining soil and avoiding overwatering are the best preventative measures for crown rot.
