Growth Conditions for Convolvulus multifidus Thunb.
Light Requirements: Convolvulus multifidus Thunb. prefers to grow in full sun exposure. The plant can tolerate partial shade, but it may result in reduced flowering and stunted growth.
Temperature: The ideal temperature range for the growth of Convolvulus multifidus Thunb. is between 20 and 25 degrees Celsius during the day. At night, the temperature should not drop below 15 degrees Celsius. The plant can tolerate some frost but is not suitable for growing in very cold temperatures.
Soil Requirements: The plants grow well in well-drained soils that are nutrient-rich and have a pH range between 6.0 and 7.5. The soil should also be loose and have adequate organic matter to allow the plant's roots to spread easily. Sandy soils with low nutrient content should be amended with organic matter to improve the soil quality for growing this plant.
Water Requirements: Convolvulus multifidus Thunb. requires moderate watering during the growing season, mainly when the soil becomes dry. However, overwatering can cause root rot, which can be detrimental to the plant's health.
Growing Season: The best time to grow Convolvulus multifidus Thunb. is during the spring and summer months when temperatures are mild and favourable for the plant's growth. Winter months can be harsh, and frost can damage the plant.
Fertilization: It is recommended to fertilize the plant regularly with a balanced fertilizer during the growing season to support its growth and increase the number of flowers. Over-fertilization should be avoided as it can lead to excessive vegetative growth and poor flowering.

Propagation of Convolvulus multifidus Thunb.
Convolvulus multifidus Thunb. can be propagated by seeds, stem cuttings, and division.
Seeds
Seeds of Convolvulus multifidus Thunb. can be sown directly into the soil or started indoors. For direct sowing, the soil should be well-draining and fertile. The best time to sow the seeds is in the spring when the soil temperature has warmed up. Sow the seeds 1cm deep and keep the soil moist until the seedlings emerge. Thin the seedlings to 15cm apart when they are 5cm tall.
For indoor sowing, use a well-draining potting mix and sow the seeds 1cm deep in small pots. Place the pots in a warm, bright area and keep the soil moist. When the seedlings emerge, transplant them to larger pots. Harden off the seedlings by exposing them to outdoor conditions for a few days before transplanting them to the garden.
Stem cuttings
Stem cuttings of Convolvulus multifidus Thunb. can be taken in the summer when the plant is actively growing. Select a healthy stem that has several leaves. Cut the stem 7-10cm below the leaf node. Remove the lower leaves and dip the cut end in rooting hormone powder. Plant the stem cutting in a well-draining potting mix. Place the pot in a warm, bright area and keep the soil moist. When the cutting has rooted, transplant it to a larger pot or to the garden.
Division
Convolvulus multifidus Thunb. can also be propagated by division. Divide the plant in the spring or fall when it is not actively growing. Dig up the entire plant and gently separate the roots into sections. Each section should have several stems and a good root system. Replant the sections in well-draining soil and keep the soil moist until the plant is established.
Disease Management
Convolvulus multifidus Thunb. can be susceptible to various fungal diseases, such as powdery mildew and leaf spot. To manage powdery mildew, ensure proper aeration and avoid overhead watering. Additionally, remove and dispose of infected plant parts immediately. For leaf spot, maintain good sanitation practices, and avoid overhead watering as well. In severe cases, the application of a fungicide may also be necessary.
Pest Management
The Convolvulus multifidus Thunb. can also be affected by pests such as spider mites, aphids, and caterpillars. Spider mites cause damage by sucking sap from the plant, leading to yellowing and wilting of leaves. To manage spider mites, avoid overhead watering, ensuring that the plant does not dry out. Additionally, frequent washing with a strong blast of water can prevent or reduce infestations. Aphids cause damage by feeding on the sap of young leaves and stems. They secrete a sugary substance that attracts ants and promotes growth of sooty mold. To manage aphids, prune and remove infested parts and spray the plant with an insecticidal soap or neem oil. Caterpillars can also cause significant damage by defoliating the plant. To prevent caterpillar infestations, use row covers over the plants and handpick and remove any that are observed. A bacterial insecticide or Bacillus thuringiensis (Bt) can also be applied to control them.
