General Appearance:
Hibiscus furcellatus Lam. is a large, deciduous shrub that can grow up to 15 feet tall. Its leaves are large and heart-shaped, with a dark green color and a slightly fuzzy texture. The plant produces large flowers, up to 8 inches in diameter, that are typically pink or red in color with a dark center. The flowers are short-lived, lasting for a day or two before falling off. The plant prefers moist, well-drained soil and can tolerate full sun to partial shade.
Light Requirements
Hibiscus furcellatus Lam. requires a lot of bright and indirect sunlight in order to grow and thrive. They should be placed in a location where they receive at least 6 hours of sunlight in a day, and the light should be filtered through blinds or sheer curtains instead of direct sunlight.
Temperature Requirements
The plant prefers warm and humid environments with temperatures ranging from 60°F to 90°F. It does not tolerate frost or cold temperatures well and must be kept away from cold drafts. If temperatures become too low, the leaves will start to fall off, and the plant may die. It is essential for the plant to maintain a consistent temperature without too many fluctuations.
Soil Requirements
Hibiscus furcellatus Lam. requires well-draining and fertile soil to grow successfully. It should ideally be planted in soil that has a pH level between 5.5 and 6.5. The soil mixture should be rich in organic matter, with a mixture of sand, peat, and loam in equal parts. The soil should also not be allowed to dry out completely and should be kept moist, but not waterlogged.
Cultivation Methods
Hibiscus furcellatus Lam. requires a sunny location with well-drained soil. The plant can be propagated by seeds, cuttings, or layering. When starting from seeds, sow them in pots containing well-draining soil, and keep them moist. Once the seedlings are large enough, transplant them into larger containers or directly into the ground. If propagating from cuttings, take cuttings from younger branches, dip them in rooting hormone, and plant them in containers with moist soil. For layering, make a shallow cut in a lower branch, apply rooting hormone, and pin the branch to the soil. It should develop roots in a few months, and can then be separated from the parent plant.
Watering Needs
Hibiscus furcellatus Lam. prefers evenly moist soil and requires watering regularly. The soil should not be allowed to dry out completely, but it should also not be waterlogged. To check whether the plant requires watering, insert a finger into the soil. If it feels dry up to the first knuckle, water the plant. However, if the soil feels wet or moist, refrain from watering until the topsoil dries out.
Fertilization
Hibiscus furcellatus Lam. benefits from regular fertilization during the growing season. Fertilize the plant every two to three weeks using a balanced, water-soluble fertilizer for flowering plants. Alternatively, apply granular slow-release fertilizer at the beginning of the growing season and reapply it as directed. Avoid fertilizing the plant during the dormant season.
Pruning
Hibiscus furcellatus Lam. requires annual pruning to promote growth and flowering. Prune the plant in the late winter or early spring before new growth emerges. Begin by removing any dead or damaged wood and any branches that cross over each other. Cut back the remaining branches to the desired length, making sure to leave at least two or three nodes on each branch to encourage new growth. Regular pruning will keep the plant's shape in check, promote flowering, and increase the plant's overall health.
Propagation of Hibiscus furcellatus Lam.
Hibiscus furcellatus Lam., commonly known as the Philodendron-split-leaf hibiscus, is an evergreen shrub native to South America. The plant is widely cultivated for its attractive foliage, which features large, lobed, and glossy leaves that resemble a philodendron plant's leaves. Propagation of this plant is by seeds, cuttings, or layering.
Propagation by seeds
Propagation by seeds is the most common method used for growing Hibiscus furcellatus Lam. The seeds should be collected when the capsule matured, which usually takes about six to eight months after blooming. The seeds should be sown immediately, or they can be stored in dry, cool conditions for up to a year, but they have a short shelf life. When sowing the seeds, they should be placed horizontally on a moist growing medium and covered by a shallow layer of soil. The ideal temperature for seed germination is between 21°C to 27°C. Germination usually takes around two to three weeks.
Propagation by cuttings
Cuttings are another method for propagating Hibiscus furcellatus Lam. Stem cuttings should be taken from the plant during the active growing season, which is in the spring or summer. The cuttings should be 8-10 cm long, with two or three leaves. The lower leaves should be removed, and the remaining leaves should be pruned in half to reduce water loss. The cuttings should be dipped in rooting hormone and then placed in moist soil. The soil should be kept consistently moist until the cuttings begin to root, which takes about six to eight weeks.
Propagation by layering
Propagation by layering involves bending one of the lower branches of the plant downto the ground, and then making a small wound on the stem. The stem should be buried under 2-4 cm of soil, and then held down with a small rock or stake. The branch should be watered regularly, and within four to six weeks, roots will begin to form. Once roots have formed, the branch can be cut off from the parent plant and planted in its own container.
Disease and Pest Management for Hibiscus furcellatus Lam.
Hibiscus furcellatus Lam. is a beautiful tropical plant that can be grown as an ornamental. However, like other plants, it is prone to several diseases and pests. Managing these pests and diseases is crucial to maintaining the health and beauty of the plant.
Common Diseases
The plant is susceptible to several diseases, including:
- Leaf Spot: Leaf spot is a fungal disease that causes circular spots on the leaves. This disease is usually caused by humid conditions and poor air circulation. To manage this disease, remove the affected leaves and dispose of them properly. Also, ensure that the plant has adequate airflow and is not overcrowded. Applying a fungicide may also help prevent this disease.
- Root Rot: Root rot is caused by various fungi that attack the plant's roots. Signs of this disease include yellowed, wilted leaves, and the plant's general lack of vigor. To manage root rot, remove the affected parts of the plant and apply a fungicide to the soil. Water the plant only when necessary and ensure that the soil is well-draining to prevent waterlogging.
- Powdery Mildew: Powdery mildew is a fungal disease that leaves a powdery white coating on the leaves. This disease thrives in humid conditions and can quickly spread to other plants. To manage powdery mildew, remove the affected parts of the plant and dispose of them properly. Water the plant only when necessary and ensure adequate airflow around the plant. Applying a fungicide may also help prevent this disease.
Common Pests
Hibiscus furcellatus Lam. is susceptible to several pests, including:
- Aphids: These are tiny insects that feed on the plant's sap and cause yellowing and distortion of the leaves. To manage aphids, spray the plant with a strong jet of water to remove them. You may also apply insecticidal soap or neem oil to control the infestation.
- Spider Mites: These are tiny pests that suck the plant's sap and cause yellowing and wilting of the leaves. To manage spider mites, wash the plant with a strong jet of water. You may also apply insecticidal soap or neem oil to control the infestation.
