The plant is also known by different common names such as traditional gardens dweller, garden spiderling, and raynalian spiderling.
Uses
The plant is widely grown both as an ornamental plant and as a medicinal one. It has a wide range of uses in traditional and modern medicine. The roots and leaves of the five-hooked spiderling are boiled together or separately and the water extract is used to treat various ailments such as fever, coughs, stomach pains, arthritis, and edema. It is also used as a diuretic, aiding in the passage of urine and reducing the buildup of fluids in the body. In traditional African medicine, the five-hooked spiderling is used to treat gonorrhea and other sexually transmitted diseases.
General Appearance
The five-hooked spiderling is a plant that grows up to 200cm tall with a spread of about 60cm. It has a woody taproot system that goes deep into the soil surface. The plant is characterized by small, greenish-white flowers, and simple, alternate leaves. The leaves are long, slender and sharp at the end with bright green and glossy surface. The flowers are borne on a long stem and they normally appear in groups of 2-3 at the end of each branch. The fruits produced by the plant are small, rounded capsules with five hooks, hence its common name "five-hooked spiderling."
Growth conditions for Boerhavia raynalii
Boerhavia raynalii is an herbaceous flowering plant that is native to West Africa. The plant requires specific growing conditions to thrive. Here are some details about its preferred growth conditions:
Light
Boerhavia raynalii prefers full sun exposure. The plant requires at least six hours of direct sunlight per day. Indoor plants must be placed in areas with abundant natural light. When outdoors, the plant should be placed in a location with lots of sunshine.
Temperature
Boerhavia raynalii is a sub-tropical plant that performs best when grown in warm temperatures. The plant prefers temperatures ranging from 20°C to 32°C. Temperatures below 15°C can cause the plant's growth to slow down, while exposure to frost will damage or kill the plant. The plant should be guarded against strong winds that can cause physical damage.
Soil requirements
Boerhavia raynalii thrives in well-draining, sandy loam soils with a pH range of 6.5 to 7.5. The plant prefers soils rich in organic matter but can grow in marginal soils if the correct amendments are added. The soil must be moist but not soggy because the plant is sensitive to waterlogging. Adding compost or organic matter to the soil can improve soil drainage and moisture retention. The plant can be fertilized with a balanced fertilizer every two weeks from spring until fall.
Cultivation of Boerhavia raynalii
Boerhavia raynalii is a hardy, shrubby plant that thrives in a range of soil types, including sandy or clay soils. It grows best in full sun or partial shade and requires minimal care once established.
Watering Needs
The Boerhavia raynalii plant is drought-tolerant and requires watering once a week, especially during dry seasons. When watering, it is essential to give ample water to saturate the roots. Avoid overwatering, as this may lead to root rot.
Fertilization
Boerhavia raynalii thrives in nutrient-rich soils and benefits from regular fertilization. Apply a balanced fertilizer every two months during the growing season to promote healthy growth and flowering. However, take care not to over-fertilize, which may damage the plant.
Pruning
Pruning is an essential aspect of maintaining a healthy Boerhavia raynalii plant. Cut back any dead or diseased stems and branches to promote healthy growth. Additionally, prune back any overgrown stems or branches to maintain an attractive, compact shape. Prune the plant after flowering in late summer to encourage new growth for the next season.
Propagation of Boerhavia raynalii
Boerhavia raynalii is a perennial plant that belongs to the family Nyctaginaceae. This plant can be propagated via different methods which are described below:
Seed Propagation
The easiest and commonly used method for propagating Boerhavia raynalii is through seeds. Collect the seeds from the mature fruits by gently rubbing them between the fingers. Sow the seeds in a well-draining seed tray that has been filled with sandy soil. Press the seeds lightly into the soil and cover them with a thin layer of soil. Keep the tray in a warm and bright area, watering lightly once a day. The seeds should germinate within 14 to 21 days, and the seedlings can be transplanted into individual pots once they have developed at least two true leaves.
Cutting Propagation
Boerhavia raynalii can also be propagated through stem cuttings. Take cuttings of the stem from the mother plant, making sure that each cutting is around 8cm in length and has at least two to three leaves. Then dip the base of the stem cuttings in a rooting hormone and plant them in prepared soil filled pots. The pot should be placed in a well-lit area, but not in direct sunlight. Keep the soil moist by watering regularly. In four to six weeks, the cuttings should establish roots and start to produce new growth.
Division Propagation
Another propagation method of Boerhavia raynalii is through division. Divide the mother plant into two or more sections, making sure that each section has its roots and one or two stems. Then plant each section in a new container filled with the soil mixture. Water the newly planted sections lightly, and make sure to keep the soil moist for the first few weeks. The plant will take some time to settle in, but with proper care, it should thrive.
Disease Management
Boerhavia raynalii is not highly susceptible to diseases. However, it can still be affected by some diseases like fungal infections and powdery mildew. These diseases are characterized by the appearance of white or grayish patches on the leaves, stem, and buds.
To manage fungal infections, always provide good air circulation around the plants by spacing them appropriately. Avoid watering the leaves and stem, as this can create a conducive environment for fungal growth. You can also apply copper-based fungicides to protect the plant from fungal infections.
Powdery mildew can be managed by removing infected plant parts and treating the plant with fungicides. Ensure that your plants have good air circulation, and avoid overcrowding to prevent powdery mildew infections.
Pest Management
Boerhavia raynalii is also relatively resistant to pests. However, it can still be affected by some common pests like aphids, whiteflies, and spider mites.
Aphids usually attack the young leaves and flowers. One way to control aphids is to spray the plant with a strong water jet to dislodge them quickly. You can also apply neem oil or insecticidal soap to control aphid attacks.
Whiteflies are small flying insects that damage the leaves by sucking sap from them. You can control whiteflies by introducing their natural predators like ladybugs and lacewings to the environment.
Spider mites are tiny pests that cause significant damage to leaves by sucking sap. You can prevent spider mite attacks by keeping the plant in a humid environment and regularly spraying it with water. You can also introduce predator mites to the environment to control spider mite populations.
