General Appearance
Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton is a sprawling perennial herb that grows up to 1 meter in length. The leaves are alternate and lance-shaped, measuring up to 20 cm in length. The flowers are small and blue in color, comprising three petals. Each flower lasts for only one day and blooms in the morning, hence the common name "dayflower". The plant also produces capsule fruits, which contain small black seeds.
Light Requirements
Commelina erecta L. subsp. livingstonii requires full sun to partial shade to thrive. This plant species prefers bright but indirect light with some protection from the intense afternoon sun.
Temperature Requirements
The ideal temperature range for Commelina erecta L. subsp. livingstonii cultivation is between 20°C and 30°C. This plant species can tolerate frost but prefers warmer temperature conditions for optimal growth.
Soil Requirements
Commelina erecta L. subsp. livingstonii prefers well-draining soils that are rich in organic matter. The soil pH range should be slightly acidic to neutral (pH 5.5-7.0) for optimal growth. Additionally, this plant species can tolerate a wide range of soils, including sandy, loamy, or clay soils.
Cultivation
Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton, commonly known as Livingston's Dayflower, is a hardy plant that is native to southern Africa. It can grow in a variety of soils and is adapted to both full sun and partial shade.
When planting, it is essential to ensure that the soil is well-drained and that there is adequate space for growth. The ideal temperature for growing Livingston's Dayflower is between 18-22°C (64-72°F).
Propagation of the plant can be done through seeds or cuttings.
Watering Needs
Livingston's Dayflower requires moderate watering. Overwatering should be avoided as it can lead to root rot. It is best to water the plant when the soil is dry to the touch. During the summer months, it may need to be watered more frequently.
One way to ensure that the plant is getting enough water is to check the moisture level of the soil. A simple test is to push a finger into the soil. If it feels slightly moist, then the plant does not need to be watered.
Fertilization
During the growing season, Livingston's Dayflower can benefit from regular fertilization. A balanced fertilizer, with equal or near-equal proportions of Nitrogen, Phosphorus, and Potassium (N-P-K), can be used every two to three weeks. Alternatively, compost or organic fertilizer can be added to the soil in the spring.
It's important not to over-fertilize the plant, as this can lead to excessive growth and weak stems.
Pruning
Pruning needs for Livingston's Dayflower are minimal. Snipping off wilted or dead leaves and blooms can create a neater appearance and encourage new growth. If necessary, it is possible to trim back the plant to control its height and width.
Cut back to just above a leaf node, this will enable the plant to produce a new stem from this point.
Propagation of Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton
Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton is a perennial herbaceous plant that belongs to the family Commelinaceae. This plant is commonly known as Livingston’s dayflower, and it is native to the African continent.
The propagation methods of Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton are mainly done by seeds or cuttings.
Propagation by seeds
The seeds of Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton should be collected when they are fully ripe and black. They should be sown during the rainy season in well-drained soil and covered lightly with soil. The seeds should germinate within 2-3 weeks.
Propagation by cuttings
Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton can also be propagated through stem cuttings. The cuttings should be taken from healthy and mature stems. The bottom leaves should be removed, and the cuttings should be dipped in rooting hormone powder to promote root growth. The cuttings should be placed in a well-draining potting mix and watered regularly. The cuttings should root within 3-4 weeks.
Overall, these propagation methods should be done carefully to ensure that the resulting plant is healthy and vigorous, and can continue to grow and thrive.
Disease Management
The subspecies Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton can be affected by different diseases that can cause significant damage to the plant and reduce its crop yield. Some of the most common diseases that affect the species are:
- Powdery mildew: This disease is characterized by the appearance of white or gray powdery patches on the leaves. To prevent or control powdery mildew, it is advisable to maintain proper air circulation and avoid watering the leaves. In advanced cases, it may be necessary to apply fungicides to control the disease.
- Anthracnose: It is a fungal disease that causes brown or black sunken spots on the leaves. To prevent or control the disease, it is necessary to remove and destroy infected plant material, maintain proper air circulation and avoid watering the leaves. Fungicides can also be applied to control the disease.
- Bacterial blight: This is a bacterial disease that causes dark brown to black water-soaked areas on the leaves. To control the disease, it is necessary to remove and destroy infected plant material and avoid overhead watering. In advanced cases, it may be necessary to apply copper-based fungicides to control the disease.
Pest Management
Commelina erecta L. subsp. livingstonii (C.B.Clarke) J.K.Morton can also be affected by different pests that can cause significant damage to the plant. Some of the most common pests that affect the species are:
- Aphids: These are small, soft-bodied insects that feed on the sap of the plant and can cause stunted growth and yellowing of the leaves. To control aphids, it is advisable to use insecticidal soap or neem oil, prune infested plant material, and introduce natural predators such as ladybugs or lacewings.
- Spider mites: These are tiny arachnids that feed on the undersides of the leaves and cause a stippled appearance. To prevent or control spider mites, it is necessary to maintain proper humidity levels, avoid over-fertilizing, and use insecticidal soap or neem oil. Predatory mites can also be introduced to control the population of spider mites.
- Caterpillars: These are the larvae of moths and butterflies that feed on the leaves of the plant and can cause significant damage. To control caterpillars, it is necessary to remove and destroy infested plant material, use Bacillus thuringiensis (Bt) or spinosad-based insecticides, and introduce natural predators such as birds or parasitic wasps.
