The ‘Orange Girl’ dahlia, with its captivating colors and abundant blooms, brings a warm and inviting presence to any garden space. Its dynamic hues and prolific flowering make it a favored choice for continuous beauty throughout the growing season, adding cheer to borders and floral arrangements.
Meet the Orange Girl Dahlia
The ‘Orange Girl’ dahlia is celebrated for its distinctive blooms, typically measuring around 4 inches across. These flowers present as a small informal decorative or waterlily type, characterized by broad, shallow double blooms with curved or flat petals. Initially, petals emerge bright orange, gradually softening to a burnished copper with subtle pink and bronze undertones as they mature. This cultivar develops into a bushy plant, reaching a height of approximately 3 to 4 feet. Its robust growth habit ensures continuous production of eye-catching flowers from summer until the first significant frost.
Cultivating Your Orange Girl Dahlia
Site Selection and Soil Preparation
Cultivating a thriving ‘Orange Girl’ dahlia begins with selecting the right garden location. These dahlias flourish in areas that receive full sunlight, ideally six to eight hours of direct sun exposure each day. Protection from strong winds can also benefit their upright growth.
‘Orange Girl’ dahlias prefer well-draining, rich, and organic soil. An ideal soil pH ranges between 6.0 and 7.5, indicating a slightly acidic to neutral preference. If your garden has heavy clay soil, amend it with generous amounts of aged compost or manure to improve drainage and provide essential nutrients.
Planting Dahlia Tubers
Plant ‘Orange Girl’ dahlia tubers in spring, after the last threat of frost has passed and the soil temperature has warmed to at least 60°F (15°C). Dig a hole about 3 to 6 inches deep and place the tuber horizontally with the “eye” or growing point facing upwards. Cover the tuber with a few inches of soil initially, gradually filling the hole as the sprout emerges.
Proper spacing is important for air circulation and plant development. Position ‘Orange Girl’ tubers about 12 to 18 inches apart. This allows each plant ample room to grow without competing for resources, contributing to healthier foliage and more abundant blooms.
Watering Needs
After planting, water the tubers once, then refrain from further watering until you observe the first green sprouts. Overwatering newly planted tubers before they sprout can lead to rot. Once the dahlia has sprouted, consistent and deep watering is beneficial.
Aim to water your ‘Orange Girl’ dahlias deeply once or twice a week, allowing the top inch or two of soil to dry out between waterings. During hot, dry weather, increase watering frequency to ensure the soil remains adequately moist.
Fertilizing for Blooms
To encourage robust growth and continuous flowering, ‘Orange Girl’ dahlias benefit from balanced fertilization. They prefer fertilizers low in nitrogen but higher in potassium and phosphorus, such as a 5-10-10 or 5-10-15 formulation. This nutrient balance promotes flower development over excessive leafy growth.
Begin applying fertilizer approximately 30 days after planting, and continue every three to four weeks throughout the growing season until September. Organic options like processed cow or steer manure can also enrich the soil. Water the plant thoroughly before applying fertilizer to prevent root burn.
Staking and Support
Given their mature height of 3 to 4 feet and prolific blooming, ‘Orange Girl’ dahlias often require staking. Install stakes at the time of planting to avoid damaging developing tubers later.
As the dahlia grows, gently tie the stems to the stakes using soft garden twine or plant ties. Regular tying every foot or so up the stem will ensure the plant remains upright and tidy, supporting abundant blooms throughout the season.
Deadheading for Continuous Flowering
Deadheading, the practice of removing spent blooms, is important for continuous flowering in ‘Orange Girl’ dahlias. This encourages the plant to produce new flower buds instead of expending energy on seed production. Regularly removing faded flowers maintains the plant’s vigor.
To deadhead effectively, use clean, sharp garden scissors to snip spent dahlia blooms. Make the cut just above the point where the flower stem intersects with a leaf or a side shoot.
Winter Care for Orange Girl Dahlias
Preparing for Dormancy
As a tender perennial, the ‘Orange Girl’ dahlia requires specific care to survive colder months in non-hardy zones. Once the first hard frost blackens the foliage, prepare the dahlia for its winter rest by cutting back the top growth, leaving approximately 2 to 4 inches of stem above the ground.
Digging and Storing Tubers
Carefully dig up the dahlia tubers. Gently remove any excess soil and allow them to dry for a few days in a frost-free location away from direct sunlight.
Once dry, remove any remaining soil and trim stems, leaving about 1 to 2 inches attached to the tuber clump. Store tubers in a ventilated container, such as a box or basket, layered with a medium like peat moss, clean wood shavings, or vermiculite. Maintain a storage temperature between 40-50°F (4.4-10°C) and proper humidity to prevent drying or rotting.
Troubleshooting Common Issues
‘Orange Girl’ dahlias can encounter pests or diseases. Common pests include slugs, snails, earwigs, aphids, and spider mites. Diseases like powdery mildew, root rot, and botrytis can also occur.
Addressing these issues often involves cultural adjustments. Ensure adequate spacing between plants to improve air circulation, which helps prevent fungal diseases. Proper watering techniques, avoiding overhead irrigation, and allowing the soil to dry slightly between waterings reduce the risk of root rot and other moisture-related problems.
For pests, strong sprays of water can dislodge aphids. Maintaining a tidy garden space reduces hiding spots for slugs and earwigs. Consult local gardening resources for specific, environmentally friendly solutions if problems persist.
