Growth Conditions of Nasturtium microcapsum Engl. & Gilg
Nasturtium microcapsum Engl. & Gilg, commonly known as the trailing watercress, is a delicate herbaceous plant that belongs to the Tropaeolaceae family. This plant is native to East Africa, where it thrives in damp habitats like river banks and wet meadows. Here are some growth conditions required for the optimum growth of Nasturtium microcapsum:
Light
Nasturtium microcapsum requires a minimum of 6 hours of direct sunlight to grow and flourish. When possible, it is best to provide the plant with full sun exposure throughout the day as they need high-intensity light for proper photosynthesis. Avoid placing the plant in shaded areas as it may lead to stunted growth and reduced leaf sizes.
Temperature
The ideal temperature range for the growth of Nasturtium microcapsum is between 16°C to 24°C. However, the plant can tolerate temperatures between 10°C to 30°C. It is best to avoid exposing the plant to extreme temperatures as it may lead to leaf burn or cause the plant to go dormant.
Soil
Nasturtium microcapsum thrives in moist and well-draining soil. The optimal pH range for the plant is between 6.0 to 7.5. The soil should be rich in organic matter and capable of holding moisture for more extended periods without becoming waterlogged. Adding compost to the soil before planting can help provide the necessary nutrients required for the plant's growth.
Providing these growth conditions will enable Nasturtium microcapsum to grow into mature plants, producing white to pink flowers that bloom in summer. The trailing watercress is an ideal indoor or outdoor plant that requires minimal maintenance and provides a lush green look to any garden or space.
Cultivation methods
Nasturtium microcapsum Engl. & Gilg, commonly known as the Andean nasturtium, is a beautiful plant that is quite easy to cultivate. It is a hardy perennial that can grow up to 30 cm in height and prefers well-drained soil with a pH between 6.1-7.8. It thrives in full sun or partial shade and can be propagated by seeds or cuttings. When planting seeds, ensure that they are sown at a depth of about 1-2 cm and spaced 30 cm apart. Andean nasturtiums can also be propagated through division in early spring or fall.
Watering needs
Andean nasturtiums require moderate watering during the growing season. The plant should be watered thoroughly once or twice per week, depending on the weather conditions. The soil should be allowed to dry out slightly before the next watering to prevent overwatering and root rot. These plants are drought-tolerant, but consistent watering will help the plant produce more flowers and maintain its health. In dry and hot regions, it is advisable to water the plant more frequently.
Fertilization
To keep the Andean nasturtium growing well, it is important to fertilize the soil occasionally. Apply a balanced fertilizer, such as 10-10-10, once per month during the growing season. This plant can also be fertilized using organic compost or manure. It is important not to over-fertilize as this may promote excess foliage growth rather than promoting the growth of the plant itself.
Pruning
Andean nasturtiums generally do not require pruning, but occasional removal of dead, damaged, or diseased stems can be done to maintain the plant's appearance. It is advisable to prune the plants in early spring, just before the growing season, to promote growth and better flower production. Pinching back the young stems can also encourage branching and produce a bushier plant. You can also deadhead the flowers as they fade to prolong the flowering period.
Propagation of Nasturtium microcapsum Engl. & Gilg
Nasturtium microcapsum Engl. & Gilg, commonly known as the "dwarf yellow watercress," is a flowering plant species that belongs to the Brassicaceae family. It is found in Africa, specifically in the tropical regions of Tanzania and Kenya. Propagation is the process of reproducing this species either sexually or asexually to increase its population.
Sexual Propagation
Sexual propagation in Nasturtium microcapsum Engl. & Gilg can be achieved through seeds. The seeds are small and should be sown in a prepared bed or container filled with rich, moist soil. The ideal time to sow the seeds is in late winter or early spring in warm temperatures ranging from 20-25°C.
After sowing, the bed or container should be placed in a location with bright but indirect light. The soil should be kept moist, and germination should occur within 7 to 14 days. The seedlings should be regularly watered and transplanted to larger pots once they have grown two true leaves.
Asexual Propagation
Asexual propagation can be achieved by stem cutting. The cuttings should be taken from the parent plant during the growing season, which is usually in spring or early summer. The cuttings should be 10-15 cm long and should be made from healthy, unflowered shoots.
The cuttings should be immersed in rooting hormone and then planted in a prepared bed or container filled with well-drained soil. The soil should be kept moist, and the temperature should be kept between 20-25°C. The cuttings should root within 21 to 28 days, and they can be transplanted to larger pots or a permanent location.
In conclusion, Nasturtium microcapsum Engl. & Gilg can be propagated by seeds or stem cuttings. Proper care and attention to the growing conditions should be given to ensure successful propagation.
Disease and Pest Management for Nasturtium Microcapsum Engl. & Gilg
Nasturtium microcapsum Engl. & Gilg is an herbaceous plant species that belongs to the family Tropaeolaceae. It is a popular ornamental plant, mostly grown for its attractive, colorful flowers and edible leaves. However, the plant is prone to various diseases and pests that can affect its growth and quality. Here are some of the common diseases and pests that might affect the plant and ways to manage them effectively.
Common Diseases that Affect Nasturtium Microcapsum Engl. & Gilg
Bacterial Blight: Bacterial blight is a common disease that affects nasturtium plants. It is characterized by the appearance of dark spots on the leaves, stems, and flowers of the plant. The spots may enlarge and merge, causing the affected parts to wither and die. To manage bacterial blight, remove and destroy the infected parts of the plant. Avoid overhead irrigation as it can spread the disease. Use copper-based fungicides to control the spread of the bacteria.
Fungal Leaf Spot: Fungal leaf spot is another common disease that affects nasturtium plants. It is caused by various fungi that thrive in warm, humid conditions. The disease is characterized by the appearance of small, circular spots on the leaves that gradually enlarge and turn brown. To manage fungal leaf spot, remove and destroy the infected parts of the plant. Avoid overhead irrigation and maintain proper spacing between plants to promote air circulation. Use fungicides to control the spread of the disease.
Common Pests that Affect Nasturtium Microcapsum Engl. & Gilg
Aphids: Aphids are small, soft-bodied insects that feed on the plant sap. They are usually found on the undersides of the leaves and can cause the leaves to curl and distort. To manage aphids, wash the plant with a strong jet of water to dislodge and remove them. Use insecticidal soap or neem oil to control severe infestations.
Cabbage Moth: Cabbage moth is a common pest that affects nasturtium plants. The adult moths lay eggs on the leaves, and the hatched larvae feed on the leaves and stems, causing extensive damage. To manage cabbage moth, use row covers to prevent the adult moths from laying eggs on the plant. Handpick and destroy the larvae as soon as they are detected. Use Bacillus thuringiensis (Bt) to control severe infestations.
Whiteflies: Whiteflies are tiny, white insects that feed on the plant sap. They are usually found on the undersides of the leaves and can cause yellowing and wilting of the leaves. To manage whiteflies, use yellow sticky traps to attract and trap them. Wash the plant with a strong jet of water to dislodge and remove them. Use insecticidal soap or neem oil to control severe infestations.
By providing appropriate care, regular monitoring and the use of the above-mentioned disease and pest control measures, Nasturtium microcapsum Engl. & Gilg can thrive and remain healthy.
