Temperature Requirements
It grows well in areas with warm temperatures, preferably between 60-75°F (15-24°C). Plants can withstand some mild frost, but long periods of cold temperatures can damage or kill the plant. It thrives in tropical and subtropical climates.
Soil Requirements
The plant prefers well-draining soils with moderate to high fertility. It can tolerate various soil types, including sandy or clay soils. The ideal pH level for the soil is neutral to slightly acidic, ranging from 6.0-7.0. Regular watering is crucial for the plant to establish itself, but it should get ample drainage to prevent root rot.
Cultivation
Bidens superba Sherff, commonly known as Spanish gold, is a perennial herb that grows well in warm climates. It prefers full sunlight but can grow in partial shade. This plant requires well-drained, moderately fertile soil with a pH of 6.0 to 7.5. It is best to plant Spanish gold in the spring after the last frost or in early autumn.
Watering Needs
It is essential to keep the soil moist but not waterlogged. The plant requires regular watering during the growing season. Water the plant deeply and slowly, and make sure the water reaches the roots. During hot and dry weather, you may need to water the plant more frequently. Reduce watering during winter.
Fertilization
To promote healthy growth, use a slow-release fertilizer that is low in phosphorus. Apply the fertilizer once or twice a season, following the manufacturer's instructions. Alternatively, you can use an organic fertilizer such as compost or well-rotted manure to feed the plant during the growing season.
Pruning
Pruning is essential for maintaining the shape of the plant and promoting bushy growth. You can pinch back the tips of the stems early in the growing season to encourage branching. Deadhead the faded flowers to promote more blooms. If the plant becomes too leggy, you can prune it back by half its height in mid-summer.
Propagation of Bidens superba Sherff
Bidens superba Sherff, commonly known as the "Annual Bidens" is a beautiful and easy-to-grow plant species that belongs to the family Asteraceae. The plant is native to the United States, particularly in the states of Texas, Oklahoma, and Arkansas. Propagating the plant is relatively easy and can be done through different methods.
Propagation by Seeds
Bidens superba Sherff flowers produce seeds after blooming, and these seeds can be harvested and used for propagation. Collect the matured seeds when they turn brown in color and store them in an airtight container in a cool, dry place until ready to plant. In early spring, sow the seeds thinly on moist soil in a sunny location with well-draining soil. Cover the sowed seeds with a thin layer of soil and water gently. The seedlings should emerge in a few days. Once the seedlings are big enough, transplant them individually into pots and care for them adequately.
Propagation by Cuttings
Bidens superba Sherff can also be propagated by cuttings. Take 3-4 inches cuttings from the green, non-flowering sections of the plant. Dip the base of the cuttings in rooting hormone powder and then place them in well-draining potting soil or peat moss. Water the cuttings gently and keep them in a warm and humid location. In a few weeks, the cuttings should have developed roots and can be transplanted into larger containers or planted directly in the garden.
Propagation by Division
Bidens superba Sherff can also be propagated through division, which is appropriate for mature plants. Dig up the plant and separate the roots into several sections, ensuring each section has leaves and roots. Replant these sections in well-draining soil, water gently, and care for them appropriately.
It is important to maintain soil moisture during propagation. It is also necessary to protect the newly propagated plants from direct sunlight and strong winds until they become established.
