The ideal temperature range for Convolvulus senegambiae Spreng. is between 22-32°C (71.6-89.6°F). It is a tropical plant and is adapted to warm and humid conditions, making it sensitive to frost and extreme heat. Extreme temperature variations must be avoided as the plant is quite sensitive to sudden fluctuations.
Soil Requirements
Convolvulus senegambiae Spreng. thrives in well-drained soils with a pH between 5.5 and 7.0. Sandy or loamy soils enriched with organic matter are ideal for the plant. Soil moisture levels must be consistent; the plant cannot tolerate prolonged periods of drought or waterlogging. Soil salinity must also be avoided as it can negatively affect the plant's growth.
Cultivation Method
The Convolvulus senegambiae Spreng. plant requires well-drained sandy loam soil for optimum growth. It can be grown in pots as well as in open ground. The plant needs abundant sunlight for at least four hours a day or can also thrive well in partial sunlight. Sowing needs to be done in the pre-monsoon season of April to May or in the post-monsoon seasons of October to November. It can be propagated by seed or cuttings.
Watering Needs
The watering requirements of Convolvulus senegambiae Spreng. are moderate. The plant should be watered twice a week during the growing season and once a week during winter. The soil should be allowed to dry out slightly before re-watering as the plant is sensitive to overwatering. It is advisable to water early in the morning or late in the evening to avoid scorching of the leaves due to the sun's heat.
Fertilization
The Convolvulus senegambiae Spreng. plant can be fertilized with organic manure or chemical fertilizers. Fertilization should be done during the growing season, and the application should be made at least twice a month. The use of organic manure like compost, vermicompost, and cow dung is advisable for healthier plant growth. A balanced NPK fertilizer can be used as a chemical fertilizer, with a recommended application rate of 40-50gm per plant for the entire growing season.
Pruning
The Convolvulus senegambiae Spreng. requires minimal pruning to maintain its shape and size. The plant's tips should be regularly pinched while it is young to encourage bushy growth. Dead, yellow, or damaged leaves should be pruned out as soon as possible to prevent the spread of any disease. Pinching back the plant's stems will also promote more flower production. Pruning should be done during the dormant season and when the plant is not in bloom.

Seeds
Propagation through seeds is the most common method for Convolvulus senegambiae Spreng. Seeds should be sown in a well-drained soil mix during the early spring or summer. The seeds should be planted at a depth of about 1 cm and watered regularly until they germinate in 10-15 days. Once the seedlings are large enough to handle, they can be transplanted into individual containers or planted directly into the garden.
Cuttings
Cuttings taken from Convolvulus senegambiae Spreng. can be an effective propagation method. Softwood cuttings are taken from the tips of the plant during the early summer. The cuttings should be about 10 cm long and should be planted in a well-drained potting mix. The cuttings should be watered regularly and kept in a shaded area until they have rooted, which usually takes 2-3 weeks. Once rooted, the plants can be replanted or transplanted into the garden.
Layering
Layering is another propagation method that is effective for Convolvulus senegambiae Spreng. This method involves bending a lower branch of the plant down to the ground and pegging it into place. The branch should be kept moist and protected until roots have developed, which takes about 2-3 weeks. Once rooted, the new plant can be separated from the parent plant and transplanted into a new location.
