Soil Requirements
This plant prefers well-drained, rich soils. The ideal pH range of the soil for Bidens acutiloba Sherff is 6.5 to 7.5. This plant can tolerate a wide range of soil types, including sandy, loamy, and rocky soils. However, the soil should be moist during the growing season, and the roots should not remain waterlogged.
Cultivation of Bidens acutiloba Sherff
Bidens acutiloba Sherff is a hardy, perennial plant that is relatively easy to grow. It thrives in well-draining soil that is rich in organic matter. The plant prefers full sun to partial shade and is tolerant of most growing conditions. Ideally, the plant should be planted in the spring or fall to give it time to establish itself before the hot summer months or winter frosts set in.
Watering Needs
Watering is an essential part of caring for Bidens acutiloba Sherff. The plant prefers moist soil, but it does not like to be waterlogged. Water the plant thoroughly, but allow the soil to dry out slightly between waterings. This will help prevent root rot and other fungal diseases. During the hot summer months, the plant may need to be watered more frequently to prevent the soil from drying out completely.
Fertilization
Bidens acutiloba Sherff is not a heavy feeder, but it benefits from a light application of fertilizer once every two weeks during the growing season. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Be sure to follow the instructions on the package carefully to avoid over-fertilizing the plant. Too much fertilizer can cause the plant to produce an abundance of foliage at the expense of flowers.
Pruning
Pruning is not necessary for Bidens acutiloba Sherff, but it can help keep the plant looking neat and tidy. Remove any dead or damaged foliage as soon as possible to prevent the spread of disease. Pinch back the tips of the stems in the early summer to promote bushier growth. This will also encourage the plant to produce more flowers. Cut back the plant to the ground in the fall after the first frost has killed the foliage.
Propagation of Bidens acutiloba Sherff
Bidens acutiloba Sherff, also known as Coarse-toothed Beggar-tick, is a herbaceous perennial plant native to North America. It is a member of the Asteraceae family, and it produces showy yellow flowers that bloom in late summer and early fall. This plant is relatively easy to grow, and it can be propagated through several methods.
Propagation by Seeds
The most common method of propagating Bidens acutiloba Sherff is by using seeds. The seeds can be collected from the mature plant when the seed heads have dried up. These seeds can be sown directly into the soil in the early spring. The soil should be well-drained, and the seeds should be lightly covered with soil. The germination of seeds usually takes about 7-14 days.
Propagation by Division
Bidens acutiloba Sherff can also be propagated by division. This is best done in the early spring when new growth is just starting. The plant should be dug up and the root system separated into sections containing at least one healthy shoot and a healthy root system. These divisions can then be planted directly into the soil or into pots containing a well-draining potting mix. Water the plant well after planting.
Propagation by Stem Cuttings
Another method of propagating Bidens acutiloba Sherff is by taking stem cuttings. This should be done in the early summer when the plant is actively growing. Cut a section of stem measuring about 4-6 inches long just below a leaf node. Remove the bottom leaves, leaving only a few leaves at the top. Dip the cut end of the stem in rooting hormone and plant it in a well-draining potting mix. Water the plant well after planting and keep it in a partially shaded location until it has developed strong roots.
Conclusion
Bidens acutiloba Sherff can be easily propagated through seeds, division, and stem cuttings. By using one or more of these methods, gardeners can expand their plant collection and enjoy the beauty of this North American native plant.

2. Aphids: These soft-bodied insects suck the plant's sap, causing leaves to curl and turn yellow. Aphids are easily controllable by spraying the plant with a strong jet of water or applying insecticidal soap.
3. Whiteflies: These tiny, flying insects feed on the plant's phloem and cause leaves to yellow and wilt. They also excrete a sticky substance that attracts mold. You can control whiteflies by applying insecticidal soap or neem oil.
By practicing good cultural practices, such as proper watering and fertilization, and being vigilant for signs of diseases and pests, you can keep Bidens acutiloba Sherff healthy and beautiful.
