The plant prefers warm temperatures and can tolerate high temperatures but does not survive frosty conditions. It needs a minimum temperature of 15°C to grow and can withstand temperatures up to 35°C. However, extremely high temperatures can cause the leaves to wilt, and the plant may require extra watering to remain healthy. In cooler climates, the plant can be grown in greenhouse conditions or as an annual plant, as it will not withstand freezing temperatures.
Soil Requirements
Convolvulus keniensis Standl. grows best in well-draining, moderately fertile soil. The pH of the soil should be neutral to slightly acidic (6.0-7.5). The plant prefers sandy loam, but it can tolerate a range of soil types, from loam to clay soils, as long as they are well-draining. Fertile soil will promote healthy growth and abundant flowering, but the plant can also grow in poor soil conditions with the addition of organic matter, such as compost or well-rotted manure. The soil should be kept moist but not waterlogged. Overwatering can cause root rot, which can be fatal to the plant.
Cultivation
Convolvulus keniensis Standl. is a frost-tender perennial plant that is best grown in warm and sunny locations. It prefers well-draining soils that are rich in organic matter and is typically propagated through seedlings or cuttings.
Convolvulus keniensis Standl. can be planted any time of the year but is typically planted during the spring or summer seasons. It requires a lot of sunlight and should be positioned in a place where it can receive full sun. The plant can grow up to 30 cm high and 100 cm wide, so it requires ample space to spread out.
Watering needs
Convolvulus keniensis Standl. requires moderate watering. It is important to ensure that the soil is moist during the growing season and that the plant is not waterlogged. The frequency of watering depends on the humidity levels, temperature, and soil type.
Watering should be done in the morning or evening hours to prevent evaporation and to enable the plant to absorb the water better. It is important to avoid watering the leaves and to direct the water towards the soil.
Fertilization
Convolvulus keniensis Standl. requires regular fertilization to ensure healthy growth and blooms. Fertilizer should be applied during the growing season, typically once a week. A general-purpose water-soluble fertilizer can be used, and it should be applied according to the instructions on the package.
It is important to avoid using too much fertilizer as it can cause the plant to produce excessive foliage and reduce the number of flowers.
Pruning
Convolvulus keniensis Standl. requires regular pruning to promote bushier growth and more flowers. Deadheading spent blooms helps the plant focus its energy on producing new flowers.
Pruning should be done during the growing season by cutting back the stems to a node just above a leaf. It is also important to remove any dead or damaged stems to prevent the spread of disease.
During the winter season, Convolvulus keniensis Standl. can be cut back severely to promote new growth in the spring.
Propagation of Convolvulus keniensis Standl.
Convolvulus keniensis Standl. is a climbing shrub that is native to Africa. The plant is known for its beautiful pink, trumpet-shaped flowers that bloom during the summer months. Propagation of this plant can be done using methods such as:
Seed Propagation
Propagation of Convolvulus keniensis Standl. using seeds is a straightforward process. The seeds are readily available in nurseries and online. To start, soak the seeds in water for a few hours until they swell up. Plant the seeds in a small pot filled with well-draining soil. Cover the seeds with a thin layer of soil, and keep the pot in a warm and bright location. Water the pot regularly, and within a week or two, the seeds should germinate. Once the seedlings have grown a few leaves, they can be transplanted to a larger pot or outdoors.
Cuttings Propagation
Propagation of Convolvulus keniensis Standl. using cuttings is another viable option. Take a few cuttings of the plant in the spring or summer when the plant is in its active growth phase. Choose stems that are healthy and have at least two nodes. Remove the bottom leaves from the cuttings and dip the cut end in rooting hormone. Plant the cutting in well-draining soil and keep it in a bright and warm location. Within a few weeks, the cutting should root and start growing. Once the plant is well-established, it can be transplanted to a larger pot or outdoors.
Division Propagation
Propagation of Convolvulus keniensis Standl. using division is also possible. Dig up the plant and gently separate the roots into smaller clumps. Each clump should have at least one stem and some healthy roots. Plant the clumps in well-draining soil and keep it in a bright and warm location. Within a few weeks, the plant should start growing and producing flowers. Once the plant is well-established, it can be transplanted to a larger pot or outdoors.
