Light Requirements
Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse requires full sun exposure to grow properly. It cannot thrive in shady, dimly lit areas. Thus, it is best to plant this species in open areas with direct sunlight, preferably where it can receive at least six hours of direct sunlight daily.
Temperature Requirements
The ideal temperature range for the growth of Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse is between 20°C to 30°C. This species can tolerate hot environments, but its growth is stunted by extremely high temperatures above 35°C. Additionally, it cannot tolerate frost and freezing temperatures.
Soil Requirements
Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse prefers well-drained and moist soils for healthy growth, but it can tolerate different soil types. However, the soil must be fertile, aerated, and rich in organic matter to support healthy growth. This species prefers slightly acidic soils with a pH ranging between 5.5 and 7.5.
Cultivation Methods
Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse, commonly known as the bush morning glory, is a hardy plant that grows well in most soils, whether sandy, loamy, or clayey. It also thrives in a broad range of temperatures, from cool to hot. The plant prefers full sun and can tolerate partial shade, but it may not flower as profusely in shady areas.
When planting, put the seeds about 6-8 inches apart and at a depth of around 2-3 inches. Water the seeds regularly until they germinate, usually within 2-4 weeks. The plant can also be propagated from cuttings taken in late spring or early summer, and rooted in soil or water.
Watering Needs
Water your convolvulus plant regularly, especially during the warmer months, to keep the soil moist. However, ensure it is not waterlogged, as excess water can lead to root rot or other fungal diseases. Once the plant is established and rooted, you can reduce watering, as the plant is somewhat drought-tolerant. A good way to check whether the soil is moist enough is to dig a small hole with a trowel and feel the soil depth inside.
Fertilization
Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse does not require excessive fertilization, and overly nutrient-rich soil can hinder the abundance of flowers. Therefore, use a balanced, slow-release fertilizer, such as a 10-10-10 mixture, to fertilize the soil just before planting or during the growing season. Be careful not to over-fertilize, as this can damage the plant roots and reduce the flowering performance.
Pruning
Pruning convolvulus is usually not necessary, but you can pinch or cut back the tips of the plant if it becomes too leggy or straggly. Pruning helps to encourage bushy growth and increase the number of flowers. Some gardeners prefer to deadhead the flowers, which means cutting off any spent blooms so that new ones can grow, extending the blooming period and the plant's aesthetic appeal. However, it's essential to avoid excessive pruning, as the plant's growth may be adversely affected.
Propagation of Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse
Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse, commonly known as Bushveld Bindweed or Transvaal Bindweed, can be propagated by various methods:
Seed Propagation
Propagation by seeds is the most common and efficient method for Convolvulus natalensis. The seeds are small, hard, and a light brown color. Sow the seeds in the early spring or autumn in a well-drained seed starting mix. The soil temperature should be kept between 15-20°C. Seeds may take 7-14 days to germinate. When the seedlings reach a sufficient size, they can be transplanted into individual pots. Afterward, they can be transferred to the garden or the desired location.
Cutting Propagation
The bushveld bindweed can also be propagated by stem cuttings. Take 7 to 10cm long cuttings and plant them in a well-draining mix of sand, peat moss, or perlite. Keep the cuttings moist and covered with plastic or a clear plastic bag to maintain humidity. The cuttings should be rooted after four to six weeks and can then be transplanted into a pot or directly into the garden.
Division
An established Convolvulus natalensis plant can be divided when it becomes overcrowded, preferably in spring. Dig up the plant from the ground and separate the root ball into sections. Ensure each division has shoots and roots, then replant each section in a new location or pot. Keep the newly transplanted divisions well-watered until they establish themselves.
Disease Management
The plant Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse may be susceptible to various diseases that can adversely affect its growth and production. Here are some of the most common ones and how to manage them:
Fungal Diseases
Fungal diseases such as powdery mildew, rust, and leaf spot can affect the leaves and stems of the plant. Fungicides, such as copper-based sprays, can help manage these diseases. It's essential to follow all label instructions for the application of fungicides.
Bacterial Diseases
Bacterial diseases like bacterial leaf spot may cause water-soaked spots to appear on leaves and stems. These spots may enlarge and become necrotic. Preventative measures, such as using clean seeds and avoiding overhead watering, can be taken to manage this disease. Infected plants should be removed and destroyed.
Viral Diseases
Viruses can cause a wide range of symptoms on plants, including stunted growth, distorted leaves, and discoloration. There is no cure for viral diseases, and infected plants should be removed and destroyed to prevent the spread of viruses.
Pest Management
Various pests can also negatively impact the growth and production of Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse. Here are some of the most common ones and how to manage them:
Aphids
Aphids are tiny insects that feed on plant sap, causing leaves to curl and become distorted. They can be managed by washing them off the plant with a strong stream of water or treating the plant with insecticidal soap or neem oil.
Mites
Mites are another pest that can cause significant damage to plants. They feed on the leaves and stems of Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse and can cause discoloration and leaf drop. Applying a miticide according to label instructions can help manage mite infestations.
Caterpillars
Caterpillars may feed on the leaves of the plant, resulting in damage and defoliation. Handpicking the caterpillars from the plant or using Bacillus thuringiensis (BT) sprays can help manage this pest.
Overall, taking preventative measures such as maintaining proper growing conditions and addressing problems as soon as they arise is crucial in managing diseases and pests that may affect Convolvulus natalensis Bernh. ex Krauss var. transvaalensis (Schltr.) A.Meeuse.
