Crotalaria incana L. forma lanata R.Wilczek is known by various common names such as Woolly Rattlepod, Woolly Crotalaria, and Hairypod Rattlebox.Light Requirements
Crotalaria incana L. forma lanata R.Wilczek is native to tropical regions and requires full sun exposure to grow optimally. It is a sun-loving plant and needs to receive at least 6 hours of direct sunlight every day. Therefore, it is recommended to plant it in an open area where it can receive maximum light.
Temperature Requirements
Crotalaria incana L. forma lanata R.Wilczek prefers warm temperatures and cannot withstand frost. It grows well in temperatures ranging from 20°C-30°C. It can tolerate short periods of drought but cannot survive long, dry spells. Therefore, it is essential to water the plant regularly during the hot and dry months.
Soil Requirements
Crotalaria incana L. forma lanata R.Wilczek requires a well-draining, fertile soil to grow optimally. It can grow in a range of soils, including sandy, loamy, and clay soils, as long as they have good drainage. It prefers a slightly acidic to neutral soil with a pH range of 6 to 7.5. The soil should be rich in organic matter, and adding compost or well-rotted manure to the soil can help improve soil fertility.
Cultivation of Crotalaria incana L. forma lanata R.Wilczek
Crotalaria incana L. forma lanata R.Wilczek is commonly known as the Woolly Rattlepod. It is a hardy, fast-growing plant that can adapt to a wide range of environmental conditions. Here are some guidelines for cultivating this plant:
- Sowing: Woolly Rattlepod can be grown from seed. Sow the seeds in well-draining soil in a sunny location. The best time to sow the seeds is in the spring, after the last frost.
- Soil: This plant prefers well-drained soil. It can grow in poor soil conditions as well, but the growth rate will be affected.
- Location: Woolly Rattlepod thrives in full sun but can tolerate partial shade. It grows well in areas with a warm climate.
- Germination: The seeds germinate in 14-21 days in warm soil. Keep the soil moist but not too wet during the germination process.
- Spacing: The plants should be spaced 30-50 cm apart to ensure that they have enough space to grow.
Watering needs of Crotalaria incana L. forma lanata R.Wilczek
The Woolly Rattlepod has moderate water requirements. Here are some tips on how to water it:
- Frequency: Water the plant once a week during the growing season. Reduce watering in the winter as the plant becomes dormant.
- Method: Water at the base of the plant to avoid getting water on the leaves. Overwatering can lead to root rot, so avoid watering too frequently or too much.
- Signs of under watering: If the leaves are wilting or turning yellow, it may indicate that the plant needs more water.
- Signs of over watering: If the leaves are turning yellow or developing mold or mildew, it may be a sign of over watering.
Fertilization of Crotalaria incana L. forma lanata R.Wilczek
Woolly Rattlepod requires regular fertilization to maintain healthy growth. Here are some guidelines for fertilizing the plant:
- Frequency: Fertilize the plant every 2-3 months during the growing season.
- Type of fertilizer: Use a balanced fertilizer, with equal parts nitrogen, phosphorus, and potassium. Alternatively, you can use a slow-release fertilizer.
- Amount: Apply the fertilizer according to the instructions on the package. Do not over-fertilize, as this can lead to excessive growth or even damage to the plant.
- Timing: Fertilize the plant in the spring, when the growing season begins, and again in mid-summer if necessary.
Pruning of Crotalaria incana L. forma lanata R.Wilczek
Pruning is an essential aspect of keeping Woolly Rattlepod healthy and attractive. Here are some tips on how to prune the plant:
- Timing: Prune the plant in the late winter or early spring, before the growing season begins.
- Method: Use a sharp, clean pair of scissors or pruning shears to cut back any dead or damaged branches or leaves. You can also trim the plant to maintain its shape and size.
- Encouraging bushiness: To encourage bushier growth, pinch back the tips of the stems.
Propagation of Crotalaria incana L. forma lanata R.Wilczek
Crotalaria incana L. forma lanata R.Wilczek is a perennial shrub species native to South Africa and widely cultivated elsewhere. It is commonly known as woolly rattlepod because of its hairy stems and seedpods. The plant is primarily propagated through seed, but can also be propagated through stem cuttings.
Propagation by Seed
The easiest and most common method of propagating Crotalaria incana L. forma lanata R.Wilczek is through seed. Seeds can be collected from mature plants once the pods have dried and turned brownish in color. Seeds can be sown directly into the soil in place where the plant will grow.
Prior to sowing, the seeds can be soaked in water for 24 hours to soften them and enhance germination. The seeds can be sown at a depth of 1 to 2 centimeters and spaced 10 to 15 centimeters apart. Germination can take anywhere from 10 to 20 days and is quicker if the seeds were soaked prior to sowing.
Propagation by Stem Cuttings
Propagation of Crotalaria incana L. forma lanata R.Wilczek through stem cuttings is also possible, but not as reliable as seed propagation.
Cuttings should be taken during the active growth period and the best time for cutting is in early spring. The cuttings should be taken from young, healthy branches at least 15 centimeters long and include at least two nodes.
The cuttings should be stripped of leaves from the lower node and dipped in rooting hormone before planting. They should then be planted in a rooting medium of sand and peat that is kept moist but not waterlogged.
The cuttings should be kept under shade and given regular misting until roots develop, which can take up to 6 weeks. Once the cuttings have rooted, they can be transplanted into pots or directly into the soil in their permanent location.
Disease Management
Crotalaria incana L. forma lanata R.Wilczek is generally resistant to most diseases, however, some fungal diseases can still affect the plant, such as:
- Anthrax: This fungal disease causes brown or black discoloration of the leaves and stems. It can be prevented by removing and destroying infected plants, practicing good sanitation, and avoiding high humidity. Fungicides can also be used to control the disease.
- Angular leaf spot: This fungal disease causes water-soaked lesions that become angular or V-shaped as they enlarge. Infected leaves may drop prematurely. The disease can be controlled by maintaining good plant hygiene, avoiding wetting the leaves during watering, and applying fungicides as necessary.
- Root rot: This fungal disease causes the roots to rot and turn brown or black. Infected plants may wilt and die. The disease can be prevented by avoiding overwatering, providing good drainage, and treating the soil with fungicides.
Pest Management
Crotalaria incana L. forma lanata R.Wilczek can be attacked by a few pests. The most common ones are:
- Aphids: These small insects suck sap from the plants, causing leaves to curl and wilt. They can be controlled by spraying the plant with insecticidal soap or neem oil.
- Spider mites: These tiny pests feed on the leaves, causing a mottled yellow appearance. They can be controlled by spraying the plant with water and applying insecticidal soap or neem oil.
- Leafhoppers: These insects cause white stippling on leaves, and can transmit diseases. They can be controlled by removing weeds and grasses near the plants, and applying insecticides as necessary.
