The plant is commonly found in tropical Africa and is known by several common names such as Woolly Strophantus, Twisted Cord Flower, and Poison Rope.Light Requirements
Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess requires a high amount of light to grow. The plant thrives in full sun or partial shade conditions and should be exposed to direct sunlight for at least six hours a day. Lack of enough sunlight can lead to stunted growth.
Temperature Requirements
The ideal temperature range for Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess is between 15-30°C. The plant grows best in warm and humid weather conditions, but it can tolerate cold temperatures of up to 10°C with a little or no frost. Exposure to high temperatures can make the plant dormant and reduce its bloom.
Soil Requirements
Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess prefers well-drained soils with a pH range of 5.5-6.5. The soil should contain an adequate amount of organic matter to support healthy growth. The plant also requires regular watering, particularly during the dry season, but the soil should not be waterlogged as it can cause root rot. Fertilizer application can help boost growth, but it should be done in moderation else it can lead to leaf shedding.
Cultivation Methods
Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess is a twining woody plant that can grow up to 10 feet in length. It requires full sun exposure, and well-drained soil that is rich in organic matter. The plant needs ample support for climbing, such as a trellis or a fence. It can be propagated through stem cuttings, division of rhizomes, or through seed germination.
Watering Needs
Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess prefers evenly moist soil but can tolerate periods of drought. Water the plant deeply once a week during the growing season and reduce the frequency of watering during the dormant season. Make sure to avoid over-watering, which can cause root rot and other fungal diseases.
Fertilization
Use a balanced fertilizer that is rich in nitrogen, phosphorus, and potassium to feed Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess. Apply the fertilizer during the growing season, which is typically from spring to early autumn. Follow the manufacturer's instructions for application rates and frequency, and avoid over-fertilizing, which can lead to excessive vegetative growth and reduced flowering.
Pruning
Prune Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess to control its size and shape. Remove dead or damaged stems as soon as possible to prevent the spread of disease. Cut back the plant in late winter or early spring to promote new growth and stimulate flowering. Trim back any unwanted growth that is obstructing a pathway, window, or view. Additionally, if the plant is getting too dense, thin out the branches to allow for better airflow, which can reduce the risk of fungal infections.
Propagation of Strophanthus Hirsutus
Strophanthus hirsutus is commonly propagated through seeds or stem cuttings. Both propagation methods have their unique set of advantages and disadvantages.
Propagation via Seeds
The seeds of Strophanthus hirsutus have a high germination rate and can be sown directly in the ground or in pots filled with a well-draining potting mix. The best time to sow the seeds is in the spring when the soil temperature has started to warm up. The seeds should be sown at a depth of around 1 to 2 cm and kept moist until they germinate.
It is worth noting that the seeds of Strophanthus hirsutus have a relatively short shelf life and should be sown as soon as possible to ensure viability.
Propagation via Stem Cuttings
Propagation via stem cuttings is a quicker and more reliable method of propagating Strophanthus hirsutus compared to seed propagation. It involves taking a stem cutting from a healthy plant and rooting it in a growing medium or water until it develops roots.
The best time to take stem cuttings is during the growing season, usually in the spring or summer. The cuttings should be taken from the upper part of the stem and should be around 10 to 15 cm long. The leaves on the lower part of the cutting should be removed, and the wound should be allowed to dry for a few hours.
The cutting can then be dipped into a rooting hormone and planted into soil or kept in water until roots develop. Once the roots have developed, the cutting can be transplanted into a larger pot or planted out into the garden.
Disease and Pest Management for Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess
Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess is susceptible to several pests and diseases. Here are some common ones and ways to manage them:
Pests:
1. Mealybugs: Mealybugs are common pests that can infest Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess. They look like white cottony masses on the plant. To manage a mealybug infestation, use a cotton swab dipped in alcohol to wipe them off. You can also apply insecticidal soap to control the population.
2. Spider Mites: Spider mites are microscopic pests that suck the sap out of leaves, causing them to turn yellow and die. To control spider mites, rinse the plant with cold water or use insecticidal soap. Insecticides containing neem oil can also be used.
3. Aphids: Aphids are small insects that can cause significant damage to Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess. They feed on the sap of the plant and can cause leaves to yellow and die. To manage aphids, spray the plant with a strong jet of water to knock them off. Insecticidal soap and neem oil can also be used to control their population.
Diseases:
1. Leaf Spot: Leaf spot is a fungal disease that causes brown spots to form on the leaves. To manage leaf spot, remove affected leaves and dispose of them. Do not overwater the plant and avoid wetting the leaves. Apply a fungicide to help prevent the spread of the disease.
2. Powdery Mildew: Powdery mildew is a fungal disease that causes a white powdery coating to form on the leaves. To manage powdery mildew, prune affected leaves and dispose of them. Avoid overhead watering and increase air circulation around the plant. Apply a fungicide to control the spread of the disease.
3. Root Rot: Root rot is a fungal disease that causes the roots to rot, leading to wilting and death of the plant. To manage root rot, avoid overwatering and ensure proper drainage. Remove affected plants and avoid planting Strophanthus hirsutus H.E.Hess x S. intermedius Pax ex H.E.Hess in the same soil. Apply a fungicide to prevent the disease from spreading to other plants.
