Overview
Convolvulus capillaceus Kunth, also known as blue rock bindweed, is a species of flowering plant in the Convolvulaceae family. It is a trailing perennial herb that is native to South America but can now be found in other parts of the world.
Common Names
The plant has a variety of common names, including blue rock bindweed, hair-like bindweed, nematanthus convolvulus, and dune morning-glory.
Appearance
The Convolvulus capillaceus Kunth plant has a thin, wiry stem that can grow up to four feet long. Its leaves are small, around 1 cm long and 3 mm wide, with a green color. The flowers are blue or purple and have a funnel-like shape, with a diameter of around 1.5 cm. They bloom from summer to autumn, and the fruit is a capsule that is 5-6 mm in diameter.
Uses
Convolvulus capillaceus Kunth has several uses. In Peru, it is used as a diuretic and for the treatment of wounds and skin problems. The plant also has potential medicinal properties and is being studied for its effects on cancer, inflammation, and pain. Additionally, it is grown as an ornamental plant in gardens and can be used as a ground cover due to its trailing habit.
Light Requirements
Convolvulus capillaceus Kunth prefers full sunlight to partial shade to grow and develop optimally. It can grow well in direct sunlight, especially during its vegetative stage, which helps improve its growth and flowering rate.
Temperature Requirements
The optimal temperature for the growth and development of Convolvulus capillaceus Kunth is between 20°C and 25°C. It is a tropical and subtropical plant with high thermal requirements, so it can grow year-round in regions with these climatic characteristics.
Soil Requirements
Convolvulus capillaceus Kunth grows well in sandy or clayey loam soils that are well-drained and have a pH range of 6 to 7.5. However, the plant can tolerate a wide range of soil types as long as they are moist and not waterlogged. It requires good soil condition, with enough organic matter and nutrients to support its growth.
Cultivation methods
Convolvulus Capillaceus Kunth grows well in warm, dry climates. It prefers well-drained soil and full sunlight. These plants are relatively easy to cultivate and can withstand drought and heat. They can be propagated through seeds, stem cuttings or division of root clumps. However, it is best to start with young plants or cuttings for quicker results.
Watering needs
These plants do not require much watering, especially during the cooler months. Overwatering can lead to root rot, so it's necessary to let the soil dry out a bit before watering again. During the hotter months, these plants may require more frequent watering but be careful not to drown them. Watering early in the morning or late in the evening is best.
Fertilization
While Convolvulus Capillaceus Kunth can survive with minimal fertilization, it will thrive when properly nourished. It is best to fertilize these plants during the growing season with a slow-release fertilizer. Avoid using high nitrogen fertilizers, as they can lead to excessive leaf growth without much flowering.
Pruning
Convolvulus Capillaceus Kunth requires minimal pruning to keep them looking neat and tidy. They can be pruned lightly to encourage bushier growth and more flowers. However, avoid pruning too much or too often, as this can affect the plant's natural shape and reduce flowering.
Propagation methods for Convolvulus capillaceus Kunth
Convolvulus capillaceus Kunth, also commonly known as desert morning glory, is a beautiful plant that is native to the Southwestern United States, Mexico, and parts of South America. The plant is a low-growing shrub that produces lovely pink, funnel-shaped flowers that bloom from late spring to early summer.
Propagation of Convolvulus capillaceus Kunth is quite easy and can be achieved through various methods. Some of the common methods of propagating the plant are described below:
Seed propagation
The easiest and most common method of propagating Convolvulus capillaceus Kunth is through seed propagation. The plant produces small, black seeds that can be collected after the flowers have faded and the seed pods have dried out. The seeds should be planted in a well-draining soil mixture, and they will germinate within two to four weeks. However, it is important to note that seedlings may not be true to the parent plant's characteristics.
Cuttings propagation
Propagation through cuttings is another method that can be used for Convolvulus capillaceus Kunth. This method involves taking stem cuttings from the parent plant, removing the lower leaves, and planting the cuttings in a well-draining soil mix. The cuttings should be kept moist and in a warm, bright, and protected area until they establish roots. This method can produce true-to-the-parent plant characteristics, and the new plants will be identical to the parent plant.
Division propagation
Division propagation is another method that can be used for Convolvulus capillaceus Kunth. This method involves dividing the parent plant into smaller sections and replanting them in new locations. The divided sections should have both roots and stems, and they should be replanted in a well-draining soil mixture in areas with similar growing conditions as the parent plant.
Overall, Convolvulus capillaceus Kunth is an easy-to-grow plant that can be propagated through various methods. Whether through seed propagation, cuttings, or division, the plant can be propagated to produce new plants that are identical to the parent plant.
Disease and Pest Management for Convolvulus capillaceus Kunth
Convolvulus capillaceus Kunth, commonly known as hairy bindweed, is a flowering plant that belongs to the Convolvulaceae family. Like any other plant, it is vulnerable to many pests and diseases that can affect its growth and yield. Here are some of the most common pests and diseases that might affect Convolvulus capillaceus Kunth.
Pests
Aphids: Aphids infestation can cause leaves to become discolored, curl, and eventually die. Natural predators like ladybugs, lacewings, and parasitic wasps can help control aphid infestation. Avoid using pesticides that can harm beneficial insects.
Spider Mites: Spider mites are tiny pests that can cause leaf discoloration and spotting. They thrive in hot and dry conditions. Increasing humidity levels by misting the leaves can discourage their growth. Regularly washing the leaves of the Convolvulus capillaceus Kunth with soapy water can also help reduce their numbers.
Whiteflies: These pests suck sap from the leaves, which can lead to wilting and yellowing of the plant. Sticky traps can be used to catch adult whiteflies, and insecticidal soap can be used to manage their populations.
Diseases
Crown rot: This fungal disease can cause the plant to wilt and eventually die. To prevent its spread, avoid overwatering the plant and ensure that the soil has good drainage. Remove and destroy infected plants to prevent the spores from spreading to healthy plants.
Fusarium wilt: Fusarium wilt is a soil-borne fungal disease that causes yellowing of the leaves, wilting, and eventual death of the plant. High soil moisture and warm temperatures can stimulate its growth. To manage the disease, rotate crops with non-susceptible plants and avoid planting Convolvulus capillaceus Kunth in areas where the disease has occurred.
Mildew: Mildew is a fungal disease that causes a white powdery coating on the leaves. To manage it, remove affected leaves and stems and prune the plant regularly to improve air circulation. Fungicides can also be used to control its spread.
By following the above measures and keeping a proper check, Convolvulus capillaceus Kunth can be protected from pests and diseases, which can lead to a healthy and productive plant.
