It can survive in areas with high humidity but can be prone to fungal diseases, especially if the temperature is above 30°C (86°F).
Soil Requirements
Convolvulus cymosus Roem. & Schult. prefers well-draining soil with a pH range between 6.0-7.5. The soil should be rich in organic matter and nutrients. It can tolerate a range of soil types, including sandy soil, loamy soil, and clay soil. However, in areas with heavy clay soil, it is essential to amend the soil to improve drainage and aeration. Regular applications of a balanced fertilizer can help promote healthy growth and flowering.
Cultivation methods
Convolvulus cymosus Roem. & Schult. is a hardy plant that thrives in warm climate zones. To grow this plant, you should choose a spot that has full sun exposure. The plant grows best in well-draining soil, with a pH range of 6.5 to 7.5. As this plant has a sprawling habit, it is best to give its shoots enough space to grow and spread.
Watering needs
Convolvulus cymosus Roem. & Schult. needs regular watering to maintain its growth. As this is a drought-tolerant plant, it does not need frequent watering, only when the soil is dry to the touch should it be watered. However, it is important to ensure that the soil does not become waterlogged, which can adversely affect the plant’s growth. You should avoid watering the plant's leaves, as this can damage the foliage.
Fertilization
Convolvulus cymosus Roem. & Schult. requires regular fertilization to maintain its growth. It is recommended to apply a balanced, slow-release fertilizer every 6 to 8 weeks during the growing season. The plant also benefits from organic fertilizers such as compost or aged manure. These organic fertilizers should be worked into the soil around the plant's roots. Additionally, it would help if you mulch the plant, which will help to retain moisture and provide nutrients to the plant.
Pruning
Pruning is an essential part of caring for Convolvulus cymosus Roem. & Schult. The plant typically grows to a height of 1.5 to 2 feet, with a spread of 4 to 5 feet, so it is important to prune the plant to control its size and shape. You should prune the plant after its growing season to ensure that the new growth has enough time to develop before the next growing season. Focus on trimming back any dead or damaged shoots or branches. Additionally, the plant can be cut back periodically to promote bushier growth and vibrant blooms.
Propagation of Convolvulus cymosus Roem. & Schult.
Convolvulus cymosus Roem. & Schult. is commonly propagated by seeds and stem cuttings.
Propagation by Seeds
Seeds of Convolvulus cymosus are small and black in colour. They are sown directly into the soil or in pots. The ideal time to sow the seeds is during the spring or summer when the weather is warm. Before sowing, the soil should be well-drained and slightly moist. The seeds are sprinkled on the soil surface and covered lightly with a thin layer of soil. They should be watered regularly and should germinate within 2-3 weeks.
Propagation by Stem Cuttings
Convolvulus cymosus can be propagated by stem cuttings as well. The cuttings are taken from a healthy and mature plant during the spring or summer. The stem cuttings should be 4-6 inches long and should have at least 2-3 pairs of leaves. The lower pair of leaves should be removed, and the stem should be dipped in a rooting hormone powder. The cutting is then inserted into a pot containing well-drained soil. The pot should be kept in a warm and humid environment, and the soil should be kept slightly moist. Within a few weeks, roots should appear, and new growth will soon follow.
Disease Management for Convolvulus cymosus Roem. & Schult.
Convolvulus cymosus Roem. & Schult. is prone to several diseases that can affect the plant's growth and productivity. Here are some of the common diseases that might affect this plant:
- Fungal Leaf Spot: This disease is characterized by the appearance of dark spots on the leaves. The spots will gradually grow larger until the leaves fall off. To manage this disease, remove and destroy infected leaves and avoid overhead watering. Applying a fungicide may also help control the spread of the disease.
- Rust: Rust appears as reddish-brown spots on the leaves, stems, and flowers. This disease can cause leaf drop, stunted growth, and reduced yield. To manage rust, remove and destroy infected plant parts and avoid overhead watering. Applying a fungicide may also help prevent the spread of the disease.
- Root Rot: Root rot is caused by a soil-borne fungus that attacks the roots. Symptoms include wilting, yellowing leaves, and stunted growth. To manage this disease, avoid overwatering the plant, provide good drainage, and remove and destroy infected plants.
- Powdery Mildew: Powdery mildew appears as a white powdery substance on the leaves and stems. This disease can cause stunted growth and reduce yield. To manage powdery mildew, apply fungicides and keep the area around the plant clean and dry.
Pest Management for Convolvulus cymosus Roem. & Schult.
Convolvulus cymosus Roem. & Schult. can also be attacked by several pests that can damage the plant and reduce yield. Here are some common pests that might attack this plant:
- Aphids: Aphids are small insects that suck the sap from the plant, causing the leaves to curl and distort. To manage aphids, spray the plant with insecticidal soap or neem oil.
- Spider Mites: Spider mites are tiny pests that suck the sap from the plant. They are hard to spot but can cause the leaves to turn yellow and fall off. To manage spider mites, spray the plant with insecticidal soap or neem oil.
- Cutworms: Cutworms are the caterpillar of a moth. They cut the stem of the plant, causing the plant to fall over. To manage cutworms, handpick them off the plant or use a biological control, such as Bacillus thuringiensis.
- Leafhoppers: Leafhoppers feed on the sap of the plant and can cause yellowing and curling of leaves. To manage leafhoppers, remove weeds around the plant, as they serve as hosts to the pest, and use insecticides.
