Light Requirements
Sutera divaricata prefers to grow in full to partial sunlight. It can tolerate some shade, but the plant produces the most flowers when exposed to at least six hours of direct sunlight per day. If you plan to grow this plant indoors, it is best to place it near a south-facing window or under fluorescent light.
Temperature Requirements
The ideal temperature range for Sutera divaricata is between 60-75°F (15-24°C). It can tolerate temperatures as low as 50°F (10°C) but may experience leaf drop or stunted growth if exposed to temperatures below this range. On the other hand, if the plant is exposed to temperatures above 80°F (27°C), it may become stressed and may stop blooming.
Soil Requirements
Sutera divaricata prefers well-draining soil that is rich in organic matter. The soil pH should be slightly acidic to neutral, between 5.5-7.0. If the soil is too alkaline, the plant may experience nutrient deficiencies and may not produce as many flowers. To ensure good drainage, it is recommended to mix sand or perlite into the soil.
Cultivation Methods
The plant Sutera divaricata, commonly known as trailing lobelia or wire vine, is a favorite among gardeners because it is easy to care for and produces vibrant purple flowers that bloom throughout the growing season. To cultivate the plant, begin by selecting a location that receives partial to full sun. It prefers well-draining soil with a pH of 6.0 to 7.5 and should be planted in the spring after the last frost.
Watering Needs
Sutera divaricata thrives in moist but not water-logged soil. Therefore, it is recommended to water regularly but allow the soil to dry slightly between waterings. During the hot summer months, the plant may require more frequent watering, while in cooler temperatures, it may only need watering once a week. A watering schedule can be determined by checking the top inch of soil for dryness.
Fertilization
Sutera divaricata benefits from fertilization during the growing season, typically from early spring to early fall. A balanced fertilizer with an NPK ratio of 10-10-10 is suitable for the plant. It is recommended to feed the plant every two weeks with a diluted solution of fertilizer to avoid burning the roots. Once the blooms begin to fade, cease fertilization.
Pruning
To encourage blooming, deadheading of the fading flowers of Sutera divaricata is essential. The removal of spent blooms encourages the plant to produce more blossoms, which means continual blooms throughout the growing season. Additionally, if the plant appears leggy, it is suitable to perform a light pruning by pinching back the stems to promote bushiness.
Propagation of Sutera Divaricata
Sutera Divaricata, also known as Fairy Bells, is a beautiful plant that is extensively grown for its attractive flowers. Propagation of Sutera Divaricata can be achieved through various methods such as seeds, stem cuttings, and division of root ball.
Propagation by Seeds
One of the ways of propagating Fairy Bells is by using seeds. The seeds must be collected from mature plants and sown in seed trays. Sow the seeds in well-draining soil mix and cover them lightly with soil. Maintain moisture and keep the seed tray in a warm location until germination occurs. Once the seedlings reach about 3 inches, transplant them into pots.
Propagation through Stem Cuttings
Propagation of Sutera Divaricata can also be achieved by using stem cuttings. Take 4 to 6 inches stem cuttings that have a few leaves and no flowers. Remove the bottom leaves and dip the cut end in rooting hormone powder. Insert the cutting into moist rooting medium and maintain humidity by covering it with a plastic bag or a cloche. Once root growth is seen, transplant the cutting into a pot.
Propagation via Division of Root Ball
Sutera Divaricata can also be propagated by dividing its root ball. Carefully remove the plant from the pot and separate the root ball into sections. Replant the separated sections into separate pots with well-draining soil mix. Water the newly potted plants and keep them in a partially shady location until new growth appears.
