Light Requirements
Scaevola gaudichaudiana Cham. var. pilosa Krause is a tolerant plant and can grow in full sun or partial shade. However, it prefers bright light for optimal growth.
Temperature Requirements
This plant prefers temperatures ranging from 22-28°C during the day and 10-16°C at night. It can tolerate temperatures below 10°C but it's growth may be stunted in such conditions.
Soil Requirements
Scaevola gaudichaudiana Cham. var. pilosa Krause grows best in well-drained soils rich in organic matter. The soil should have a pH of 6.5 to 7.2. It prefers sandy loam or loam soils but can also grow in rocky or clay soils. The plant does not tolerate waterlogged or poorly drained soils.
Cultivation Methods
Scaevola gaudichaudiana Cham. var. pilosa Krause, commonly known as Pilose Fanflower, is a shrub that can be used in hanging baskets, mixed containers, or as ground cover. It requires full sun or partial shade and well-draining soil. The plant can grow up to 2 feet tall and has no significant pest or disease problems.
Propagation can be done using seed or cuttings. Seeds should be sown in early spring or early autumn in a well-draining potting mix and kept moist. Once they have germinated, the seedlings can be transplanted into containers or the ground. Cuttings should be taken from new growth in the spring or midsummer, dipped in rooting hormone, and then planted in a well-draining potting mix.
Watering Needs
Pilose Fanflower should be watered regularly but not overwatered. The soil should be allowed to dry out slightly between waterings. During hot weather or drought conditions, the plant may require more frequent watering.
It is essential to avoid getting water on the leaves and flowers, as it can cause fungal diseases. Watering should be done at the base of the plant.
Fertilization
Regular fertilization can help Pilose Fanflower to thrive. A balanced all-purpose fertilizer can be applied every month during the growing season. The fertilizer should be diluted to half-strength and applied to the soil around the base of the plant.
Pruning
Pilose Fanflower benefits from regular pruning to encourage bushy growth and prevent it from getting leggy. Pruning should be done after flowering. Deadheading spent blooms can also encourage more flowers to develop.
When pruning, use clean, sharp scissors or clippers and make cuts just above a leaf node. Cut back the stems by up to one-third of their length, but no more than that. Avoid pruning in the winter, as it can damage the plant's growth for the following season.
Propagation of Scaevola gaudichaudiana Cham. var. pilosa Krause
Scaevola gaudichaudiana Cham. var. pilosa Krause can be propagated by several methods, including:
Seed Propagation:
Seeds can be collected from the plant during the flowering season and sown in nursery beds or pots. The seeds should be sown in a well-draining mixture of sand and loam in a ratio of 1:1. The seeds should not be buried too deep, as they require light for germination. They can be simply sprinkled on the surface of the soil and lightly pressed down. The seeds should be kept moist and in a warm, well-lit space. Germination can take up to two weeks, and the seedlings can be transplanted when they reach two inches in height.
Cuttings Propagation:
Scaevola gaudichaudiana Cham. var. pilosa Krause can also be propagated through cuttings. Softwood cuttings can be taken from the plant during the growing season. They should be taken from the tips of the branches, approximately three inches long, and should have two or three leaves attached. The lower leaves should be stripped away, and the cuttings should be dipped in rooting hormone. They should then be planted in a well-draining mixture of sand and loam in a ratio of 1:1. The cuttings should be kept in a warm, well-lit space and regularly misted to prevent them from drying out. The cuttings can take up to six weeks to root, and can then be transplanted to their final location.
Division Propagation:
In mature plants, clumps can form. These clumps can be divided and planted as individual plants. Care should be taken to maintain the root structure of the individual plants. The plants should be immediately watered and kept in a warm, well-lit space. This method can be very effective, especially on well-established plants that have been often pruned.
Disease Management
Scaevola gaudichaudiana Cham. var. pilosa Krause is a resilient plant that is generally resistant to most diseases. However, it may still suffer from fungal infections such as leaf spot and powdery mildew. To prevent these diseases:
- Ensure proper air circulation by spacing plants adequately to promote good airflow.
- Water in the morning to allow time for the foliage to dry before nightfall. Avoid watering from overhead to prevent water from being retained on the foliage, and apply water directly to the soil.
- Remove any diseased leaves immediately and dispose of them away from the plant to prevent further spread of pathogens.
- Apply a fungicide if the disease is severe and persists even with other preventive measures in place.
Pest Management
Scaevola gaudichaudiana Cham. var. pilosa Krause may suffer from infestations by common pests such as aphids, spider mites, and whiteflies. To manage these pests:
- Regularly inspect the plant for signs of pest infestation such as distorted leaves, sticky residue on the leaves, or webbing.
- If pests are present, a strong blast of water can help dislodge them from the plant. Alternatively, use insecticidal soap to spray the leaves and stem of the plant.
- For severe infestations, apply an insecticide but follow the instructions on the label carefully to ensure the safety of the plant and its surroundings.
- Encourage the presence of beneficial insects such as ladybugs and lacewings that feed on aphids and other pests.
