Growing Sutera zambesica (R.E.Fr.) R.E.Fr.
Sutera zambesica, also known as Blue-Eyed Grass, is a hardy plant that can adapt to a range of growing conditions. However, for optimum growth, it is crucial to provide the plant with specific light, temperature, and soil requirements.
Light Requirements
Sutera zambesica prefers partial shade to full sun. When grown in full sun, it is essential to keep the soil moist, as too much sunlight can lead to wilting of the plant. In partial shade, the plant can tolerate longer durations without water.
Temperature Requirements
Sutera zambesica can grow well in a range of temperatures from 10-30°C. However, it is recommended to avoid planting the species in extreme heat or frost. The ideal temperature range for the plant to thrive is 15-25°C.
Soil Requirements
The plant requires well-draining soil with a pH range of 6.0-7.5. It can also grow in sandy or loamy soil but can struggle in dense clay soil. It is recommended to amend the soil with organic matter such as compost to support the plant's growth and to retain moisture.
Ensure to water Sutera zambesica regularly and keep the soil moist to help the plant maintain vibrant blooms. Fertilizing with a balanced, slow-release fertilizer can also support healthy growth.
Cultivation
Sutera zambesica (R.E.Fr.) R.E.Fr. grows best in well-drained soil that is rich in organic matter. It is a relatively low-maintenance plant that does well in both full sun and partial shade. This plant is hardy and can grow in a wide range of temperatures, making it an excellent option for gardens in different regions.
Watering needs
Sutera zambesica (R.E.Fr.) R.E.Fr. requires regular watering, but it should not be overwatered. Overwatering can cause root rot and other diseases that can damage the plant. It is best to water the plant thoroughly when the soil is dry, but not to let it sit in water for too long. The plant will require more water during the summer months when the temperatures are higher and less water during the winter months when the temperatures are lower.
Fertilization
Sutera zambesica (R.E.Fr.) R.E.Fr. benefits from a balanced fertilizer that is high in nitrogen. A fertilizer with a balanced N-P-K (nitrogen, phosphorus, potassium) ratio will help the plant grow more robustly and produce bigger flowers. It is best to fertilize the plant every two weeks during the growing season and reduce the frequency to once a month during the winter months when the plant is not growing as actively.
Pruning
Sutera zambesica (R.E.Fr.) R.E.Fr. benefits from pruning to maintain its shape and size. The best time to prune the plant is during the early spring before it starts producing new growth. This plant tends to become leggy and overgrown very quickly, so pruning is essential to keep it looking neat and healthy. Deadheading spent flowers also encourages the plant to produce more flowers and remain looking attractive for a more extended period.
Propagation of Sutera zambesica (R.E.Fr.) R.E.Fr.
Sutera zambesica, commonly known as the trailing or creeping pearlwort, is a flowering plant that belongs to the family of Scrophulariaceae. Propagation of this plant can be done using several methods.
Propagation through Seeds
Sutera zambesica can be propagated through seeds. Harvest the seeds from mature fruit capsules once they are brown and dry. Store the seeds in a cool and dry place until ready to use. Sow the seeds in a well-draining potting mix, and cover them lightly with soil. Keep the soil moist and place the container in a warm and bright location. Germination typically takes 2-4 weeks.
Propagation through Cuttings
Sutera zambesica can also be propagated through stem cuttings. Take cuttings of about 4-6 inches in length from the parent plant. Remove the leaves from the lower half of the cutting, and insert it into a well-draining potting mix. Water the soil, and place the container in a warm and bright location. The cuttings should root in 2-3 weeks.
Propagation through Division
Propagation through division is another method for propagating Sutera zambesica. During the spring, carefully remove the root system from the parent plant and separate it into smaller sections. Each division should have several stems and a healthy root system. Plant each division into a well-draining potting mix, and water the soil. Place the container in a warm and bright location. The new plants should establish quickly.
Disease and Pest Management for Sutera zambesica (R.E.Fr.) R.E.Fr.
Sutera zambesica (R.E.Fr.) R.E.Fr. is a plant that is relatively resistant to disease and pest infestation. However, it is not immune to problems that can arise from time to time.

Common Diseases
One of the most common diseases that affect Sutera zambesica is Botrytis blight. This fungal disease often appears in conditions of high humidity, low light, and cool temperatures. Symptoms include grayish-brown or black lesions on leaves, stems, and flowers. To manage Botrytis blight, it is essential to keep the plant well-ventilated, minimize overhead watering, and remove any infected plant parts. In some cases, antifungal spray may be necessary.
Another disease that can affect Sutera zambesica is powdery mildew. This disease manifests as powdery white spots on leaves, stems, and flowers. It is caused by a fungal infection and spreads rapidly in warm and humid conditions. To manage powdery mildew, it is important to ensure proper air circulation around the plant, avoid over-watering, and remove any infected plant parts. Fungicidal spray may also help control its spread.
Common Pests
Sutera zambesica is relatively resistant to pests, but certain insects can still pose a threat to its growth and health. One of the common pests that can attack Sutera zambesica is spider mites. These pests appear as tiny reddish-brown or yellow spots on leaves and can cause visible damage to the plant over time. To manage spider mites, it is important to keep the plant well-hydrated, minimize dust around it, and use insecticidal soap spray to control the population.
Another common pest that can affect Sutera zambesica is whiteflies. These insects appear as tiny white spots on the foliage and can cause damage by sucking the sap from the plant. To manage whiteflies, it is important to remove any infected plant parts, avoid over-fertilization, and use insecticidal soap spray or neem oil to control their spread.
Overall, with proper care and management, Sutera zambesica is a relatively low-maintenance plant that can thrive in a variety of conditions. By following the tips provided in this article, you can help your plant remain healthy and resistant to disease and pest infestation.
