Overview
The Nasturtium acaule Welw. is a flowering plant found in southern Africa. It belongs to the Tropaeolaceae family and is commonly known as the low-growing nasturtium.
Appearance
The low-growing nasturtium is a perennial plant that can grow up to 10cm in height. It has elongated leaves that are round and slightly heart-shaped. The leaves are dark green in color and have a slightly hairy texture. The plant produces small yellow or orange flowers that have five petals and a hollow spur. The fruit of the plant is a small capsule that contains several seeds.
Origin and Habitat
The Nasturtium acaule Welw. is native to southern Africa and is found growing in rocky areas, on the sides of hills, and in other dry habitats. The plant is adapted to drought and is well-suited to growing in sandy soils. It is also commonly found in grasslands and savannas.
Uses
The low-growing nasturtium is primarily used for ornamental purposes and is often included in rock gardens or grown in containers. The plant is also used for its medicinal properties, as it contains high levels of vitamin C and has been traditionally used to treat scurvy. The peppery taste of the leaves and flowers makes them a popular addition to salads. The plant is also known to attract bees and butterflies, making it a valuable addition to pollinator gardens.
Typical Growth Conditions for Nasturtium acaule Welw.
Nasturtium acaule Welw., commonly known as the dwarf Nasturtium, is a low-growing, herbaceous plant. It is easy to care for, making it a great choice for both novice and experienced gardeners. Understanding its typical growth conditions is essential for its proper growth and development.
Light Requirements
Nasturtium acaule Welw. thrives in full sun to partial shade conditions. Exposure to direct sunlight is essential for its proper growth and the development of its brightly colored flowers. Planting it in an area that receives at least 6 hours of direct sunlight per day is recommended. In hot climates, however, it benefits from partial shade to protect it from intense sunlight.
Temperature Requirements
Dwarf Nasturtium prefers mild temperatures ranging from 60°F (15.6°C) to 70°F (21.1°C), making it ideal for both indoor and outdoor growing. It may survive in temperatures extending beyond this range, but not in extreme heat conditions. Nasturtium acaule Welw. is also not frost-tolerant, so it requires warm weather conditions.
Soil Requirements
The plant requires well-drained soil that is nutrient-rich and slightly acidic, with a pH range of 6.0 to 7.5. The soil should be moist, but not waterlogged, as excess water can lead to the growth of root rot. Nasturtium acaule Welw. is highly adaptable and will grow in almost any type of soil, including loamy, sandy, and clay soils, as long as drainage is adequate and soil quality is high.
Cultivation of Nasturtium acaule Welw.
Nasturtium acaule Welw. is a plant that typically grows in rocky, arid areas, making it an ideal choice for xeriscape gardens. When cultivating the plant, it should be kept in mind that it thrives in well-drained soil with ample sunlight exposure. The plant can be propagated from stem cuttings or seed sowing during the warm months.
Watering Needs for Nasturtium acaule Welw.
It is important to note that Nasturtium acaule Welw. is a drought-tolerant plant and therefore does not require much water. For optimal growth, it is best to water the plant every two weeks during the growing season. Overwatering should be avoided as it can lead to root rot.
Fertilizing Nasturtium acaule Welw.
Nasturtium acaule Welw. does not require much fertilization as excessive nutrients can lead to bushy growth instead of the plant’s natural creeping habit. The application of a balanced fertilizer once a month during the growing season is enough to provide essential nutrients for the plant’s growth.
Pruning Nasturtium acaule Welw.
Pruning is not necessary for Nasturtium acaule Welw. as the plant has a creeping habit. However, deadheading can be done to promote more flowers to bloom. Any yellow, dead leaves or stems should also be removed to promote the plant’s health.
Propagation Methods of Nasturtium acaule Welw.
Nasturtium acaule Welw. is a low-growing plant that can be propagated through various methods. Here are some ways to propagate this plant:
Seed Propagation
The easiest way to propagate Nasturtium acaule Welw. is through seeds. Sow the seeds in well-drained soil during spring or fall. The seeds should be sown at a depth of 1/4 to 1/2 inch deep. The optimal temperature range for germination is between 60 and 75 degrees Fahrenheit. It takes approximately two weeks for the seeds to germinate. Once the seedlings have emerged, make sure to thin them out to give each plant enough space to grow.
Cuttings Propagation
Nasturtium acaule Welw. can also be propagated through stem cuttings. Take a cutting of about four to six inches long from a healthy, mature plant. Strip off the lower leaves and dip the cut end in rooting hormone. Place the cutting in a pot with a moistened rooting medium like perlite or vermiculite. Cover the pot with a plastic bag to maintain humidity, and keep it in a warm, bright location out of direct sunlight. In about two to four weeks, the cutting should develop roots.
Division Propagation
Nasturtium acaule Welw. can also be propagated through division. Carefully dig up the mature plant and separate it into smaller sections. Each section should have its own set of roots and stems. Replant the sections in well-draining soil and water them thoroughly. Keep the newly planted divisions in a shaded area for a few days to allow them to develop new roots before exposing them to full sun.
By following these propagation methods, you can quickly grow more Nasturtium acaule Welw. plants. Whether you choose to propagate from seeds, cuttings, or division, this plant can add a beautiful and unique touch to any garden or landscape.
Disease Management
The Nasturtium acaule Welw. is a plant that is susceptible to various diseases. Below are some common diseases that might affect the plant and their management strategies:
Fungal Diseases
Fungal diseases often attack the Nasturtium acaule Welw. and can lead to serious damage if left uncontrolled. The plant is susceptible to powdery mildew, rust, and wilting diseases. To manage fungal diseases, remove any infected plant parts and provide good air circulation around the plant to reduce moisture levels. You can also use fungicides to control severe cases of fungal infections.
Bacterial Diseases
Various bacterial diseases may attack the Nasturtium acaule Welw. Some of these diseases include bacterial spot, crown gall. To manage bacterial diseases, use pathogen-free seeds and irrigation water. You can also use copper-based fungicides to control bacterial diseases.
Pest Management
The Nasturtium acaule Welw. is susceptible to pest infestations, which could reduce the plant's productivity. Below are some common pests that might attack the plant and their management strategies:
Root Knot Nematodes
Root knot nematodes are common pests that affect the Nasturtium acaule Welw., leading to root damage and decreased productivity. To manage nematodes, solarize the soil before planting, and use pathogen-free seedlings. Apply nematicides such as carbofuran to control severe nematode infections.
Aphids
Aphids are a common pest that attacks the Nasturtium acaule Welw. and can lead to stunted growth and plant deformities. To control aphids, use insecticidal soap or neem oil on the plant. You can also introduce natural predators such as ladybugs and lacewings to feed on the aphids.
Whiteflies
Whiteflies are another pest that attacks the Nasturtium acaule Welw. and can lead to reduced yields. To manage whiteflies, use yellow sticky traps and insecticidal soap. You can also introduce natural predators such as ladybugs to feed on the whiteflies.
