In conclusion, Thesium setulosum Robyns & Lawalrée is a versatile plant that can adapt to a wide range of habitats. It requires a minimum of 4 hours of sunlight each day to maintain optimal growth, a temperature range of 15°C to 25°C, and well-draining soils with a neutral to slightly acidic pH.
Cultivation
The plant Thesium setulosum Robyns & Lawalrée belongs to the family of the Santalaceae. Its native habitat is in Africa. To cultivate this plant, it is essential to provide the necessary conditions similar to its natural habitat. The plant prefers well-drained sandy or loamy soil with a pH of around 6.5 to 7.5.
It is also advisable to place the plant where there is partial shade, which should not be too intense, or full sun, which should also be mild. The temperature should range between 22-25°C.
Watering Needs
Proper watering technique is necessary when cultivating Thesium setulosum Robyns & Lawalrée. Water the plant every three to four days or when the soil is dry to touch but not too dry. It is important not to let the soil get too dry, as it may lead to stunted growth or wilting of the plant.
Water the plant in the early morning or late evening, preferably with room temperature water, as this will reduce the amount of water lost through evaporation. Avoid overwatering, as this may create waterlogged soil leading to root rot
Fertilization
Fertilizing the Thesium setulosum Robyns & Lawalrée plant helps it to grow healthy and produce better foliage and flowers. It is recommendable to add compost manure to the soil every spring to keep the soil fertile.
It is also ideal to use a good-quality fertilizer once every two weeks during the growing season (spring to fall). The fertilizer should contain a balanced proportion (Nitrogen, Phosphorus, and Potassium) to encourage continuous growth and flowering.
Pruning
Pruning is essential to maintain the overall growth and appearance of the Thesium setulosum Robyns & Lawalrée plant. Prune the plant in late winter before the growing season begins; this helps remove any dead or damaged branches, suckers, or diseased parts of the plant.
Deadheading is another critical pruning technique that helps to encourage the growth of new foliage and flowers. Pinch off or cut off any faded flowers as they form- Do not cut or prune the plant after midsummer, as it may interfere with next year's growth.
Propagation of Thesium setulosum Robyns & Lawalrée
Thesium setulosum Robyns & Lawalrée, commonly known as spiny lacepod, is a herbaceous plant that belongs to the family Santalaceae. This plant is commonly found in sub-Saharan Africa and it grows up to 40cm in height. Propagation is an important aspect of plant reproduction and it can be achieved through different methods.
Seed propagation
Seeds are the most common method of propagating T. setulosum. To propagate this plant using seeds, the seeds should be collected as soon as they are mature and dry. Sow the seeds in a well-draining soil mix and cover them lightly with soil. Keep the soil slightly moist and place the container in a warm area with bright, indirect light. Germination of the seeds can take anywhere from 2-4 weeks.
Vegetative propagation
Vegetative propagation can also be used to propagate T. setulosum. This method involves taking cuttings from the plant and rooting them in soil. Select a healthy stem that has at least one node from which new shoots can emerge. Cuttings should be taken in the spring or early summer when the plant is actively growing. Dip the cut end of the stem in rooting hormone and plant it in a well-draining soil mix. Keep the soil moist and place a plastic bag over the cutting to increase humidity. Once the cutting has rooted, it can be removed from the plastic bag and placed in a larger container.
Division
T. setulosum can also be propagated through division. This method is best done in the spring when the plant is just beginning to grow. Dig up the entire plant and carefully divide it into smaller sections. Each section should have at least one growing point and a healthy root system. Replant the sections in a well-draining soil mix and keep the soil moist.
Disease Management
Thesium setulosum Robyns & Lawalrée plants are susceptible to certain diseases and illnesses that can affect their health and productivity. It is essential to monitor the health of the plants and take preventive measures to avoid the onset of any disease or illness. Here are some common diseases that might affect Thesium setulosum plants:
Anthracnose
Anthracnose is a fungal disease that appears as small brown spots on the leaves. Eventually, the spots enlarge and develop into lesions that can cause the leaves to fall off the plant. To prevent anthracnose, it is important to keep the plants dry and avoid overhead watering. A fungicide can also be applied to control the disease.
Crown Rot
Crown rot is a bacterial disease that affects the roots and crown of the Thesium setulosum plant and can ultimately lead to the death of the plant. Overwatering or poorly-draining soil can contribute to the development of crown rot. To prevent this disease, it is essential to allow the soil to dry out between waterings and to avoid over-fertilizing. Affected plants must be removed and destroyed to prevent the spread of the infection.
Pest Management
Thesium setulosum plants are also prone to insect pests that can damage or kill the plant. Here are some common pests that may infest Thesium setulosum:
Aphids
Aphids are small, pear-shaped insects that feed on sap from the plant, causing leaves to curl and wilt. They can also transmit viruses that can cause serious damage to the plant. To control aphids, spray the plant with soapy water or a pesticide specifically formulated for aphids.
Spider Mites
Spider mites are microscopic pests that suck sap from the plant and cause the leaves to turn yellow and fall off. Infestations usually occur in hot, dry weather. To control spider mites, increase humidity by misting the leaves or placing the plant on a tray of water. Insecticidal soap or a pesticide can also be applied to control the infestation.
Whiteflies
Whiteflies are tiny, white-winged insects that feed on the sap of the plant and produce a sticky substance that attracts other pests. They can cause leaves to yellow and wilt, and can also transmit viruses to the plant. To control whiteflies, use yellow sticky traps to capture the adults and apply a pesticide specifically formulated for whiteflies.
