Common Names
Dicoma anomala Sond. subsp. anomala is also commonly known as the 'Slangbos', 'Klapperbos', or 'Resinslag'. The common names are derived from the plant's peculiar habit of making a rattling sound when touched due to the dry and brittle nature of its leaves.
General Appearance
The plant grows up to 1 m tall and branches frequently. Its cylindrical stem is up to 4 cm in diameter and is covered in fibrous, stringy bark. The leaves are narrow and lance-shaped, arranged alternatively along the stem. The leaves' margins are toothed, and the upper side of the leaf is green, while the underside is covered with fine white hairs. The plant produces small flower-heads that are yellowish or cream-colored.
Uses
Dicoma anomala Sond. subsp. anomala has various uses. The plant's roots and leaves are used medicinally to treat several conditions such as stomach problems, skin infections, and pneumonia. The leaves are used as a substitute for tobacco and contain caffeine-like stimulants. The roots and bark are used in traditional African medicine as a snakebite remedy, and as a chewing stick to relieve toothache or for ritual purposes. The plant also has potential as a source of natural insecticides and could serve as a source of fuel.
The plant's leaves are utilized by the local people as a material for basket weaving, while the branches are used as firewood. The plant is also used for soil conservation and revegetation of degraded land, thanks to its exceptional tolerance to harsh environmental conditions such as drought and nutrient-poor soils.
Growth conditions for Dicoma anomala Sond. subsp. anomala
Dicoma anomala Sond. subsp. anomala is a perennial shrub that is native to South Africa. It is a hardy plant that can withstand different weather conditions, but it grows best in the following growth conditions:
Light
This plant thrives in full sun to partial shade. In its natural habitat, it grows along the edges of forests, but it can also grow in open areas. Therefore, it requires enough sunlight to grow and produce flowers.
Temperature
Dicoma anomala Sond. subsp. anomala is a plant that can grow in different temperature ranges. It prefers warm weather conditions ranging from 18°C to 30°C. In winter, the temperature may drop, but it can survive even in temperatures as low as -5°C, as long as it is not for a prolonged period.
Soil requirements
This plant can grow in different soil types, but it prefers well-draining soils with a pH range of 6.0-8.0. It can grow in sandy soils, loamy soils, and rocky soils. However, it cannot grow in soils that are waterlogged or those that hold too much water. Therefore, ensure that the soil is well-draining to prevent waterlogging.
These are the typical growth conditions that promote the growth and development of Dicoma anomala Sond. subsp. anomala. With the right growth conditions, the plant can grow to a height of about 1.2 meters and produce yellow flowers that bloom from July to November.
Cultivation of Dicoma anomala Sond. subsp. anomala
Dicoma anomala Sond. subsp. anomala is a plant species from the Asteraceae family and is native to South Africa. This plant typically grows in sandy, well-draining soils. To cultivate it, plant it in an area with full sun exposure.
The soil must have good drainage as the plant requires limited watering in humid or rainy areas.
Watering needs of Dicoma anomala Sond. subsp. anomala
This plant species should be watered only when the soil is completely dry. The watering schedule for Dicoma anomala Sond. subsp. anomala may vary depending on the environmental conditions or its growth stage. It's important to avoid over-watering, as this can lead to root rot and other diseases that could cause plant death.
Fertilization of Dicoma anomala Sond. subsp. anomala
When cultivating Dicoma anomala Sond. subsp. anomala, it's important to note that this plant doesn't need excessive fertilization. Fertilize the plant during the growing season, which is typically in spring and summer. Use a well-balanced fertilizer recommended for flowering plants and apply it sparingly, following the manufacturer's instructions.
Pruning Dicoma anomala Sond. subsp. anomala
Prune your Dicoma anomala Sond. subsp. anomala in the growing season to remove the old, dead, or wilted branches. Avoid pruning more than 1/3 of the plant during any one session, as excessive pruning could damage the plant, leading to poor growth or death.
When removing dead stems or leaves, use a clean and sharp gardening tool to avoid introducing diseases to the plant.
Propagation of Dicoma anomala Sond. subsp. anomala
Dicoma anomala Sond. subsp. anomala is commonly propagated through seeds and cuttings.
Propagation through seeds
The plant produces seeds which can be collected and sown in a well-draining potting mix. The seeds should be sown at a depth of approximately 2-3 mm and kept moist until germination occurs, which can take 2-4 weeks. Once the seedlings are large enough to handle, they can be transplanted into individual pots or directly into the ground. It is important to keep the soil consistently moist during the initial stages of growth to ensure proper establishment.
Propagation through cuttings
Propagation through cuttings may be a preferred method for some gardeners. Stem cuttings of approximately 7-10 cm in length can be taken from the plant in the spring or summer months. The cuttings should be treated with a rooting hormone and planted in a well-draining potting mix. The cuttings should be kept in a warm, humid environment and misted regularly until roots develop, which can take 2-3 weeks. Once the roots have developed, the cuttings can be transplanted into individual pots or directly into the ground.
Disease Management for Dicoma anomala Sond. subsp. anomala
The Dicoma anomala plant can be susceptible to various diseases that might hinder its growth and eventually cause its death. A few common diseases that might affect the Dicoma anomala plant are:
- Fungal Leaf Spot: This disease causes small spots on the leaves, which may expand and cause leaves to fall off. To manage this, remove the infected leaves and apply a fungicide recommended by a local horticulturist.
- Root Rot: This disease causes the roots to rot, which may result in the plant's death. It is essential to prevent the plant from overwatering and to ensure that the soil has adequate drainage.
- Powdery Mildew: This disease causes white, powder-like substance on the plant's leaves, which can stunt growth and eventually cause death. To treat this, use a fungicide recommended by a local horticulturist.
Pest Management for Dicoma anomala Sond. subsp. anomala
Aside from diseases, Dicoma anomala plants can also be prone to pest infestations that may cause harm to the plant. Some common pests that might affect the Dicoma anomala are:
- Aphids: These pests suck the plant's sap, which can cause leaf damage, yellowing, and stunted growth. To manage this pest, apply neem oil or insecticidal soap to the affected areas.
- Caterpillars: These pests eat the plant's leaves, which can result in complete defoliation, stunted growth, and eventual death. To manage this pest, manually remove the caterpillars or apply a biological insecticide recommended by a horticulturist.
- Spider Mites: These pests suck the plant's sap, which can cause leaf yellowing, necrosis, and eventual death. To manage this pest, gently wash affected areas with a hose and apply neem oil or insecticidal soap to the affected areas.
It is important to note that prevention is always better than cure when it comes to disease and pest management. Always maintain proper hygiene, avoid overcrowding, and keep the plant healthy to prevent diseases and pests from infesting the plant.
