The plant's appearance is striking, as it has bright green leaves that are lance-shaped and up to 8 cm long. The stems are succulent and grow up to 1m long, and the flowers are usually pink, white, or purple and grow in clusters measuring up to 8 cm in length. Impatiens sylvicola is an annual or perennial herb that flowers year-round and can be propagated from seed or cuttings.
Growth Conditions for Impatiens sylvicola Burtt Davy & Greenway
Impatiens sylvicola Burtt Davy & Greenway, commonly known as forest balsam, is a shade-loving plant native to forests in East Africa. It is a perennial plant that requires the following growth conditions;
Light
Being a shade-loving plant, Impatiens sylvicola requires moderate to dense shade for optimal growth and development. The plant prefers filtered light or dappled sunlight and cannot withstand direct sunlight for extended periods.
Temperature
Impatiens sylvicola thrives in moderate temperatures ranging from 18 to 25 degrees Celsius. Temperatures above 30 degrees Celsius can lead to stunted growth and leaf wilting. In contrast, temperatures below 15 degrees Celsius can lead to leaf yellowing and fungal infections.
Soil Requirements
Impatiens sylvicola requires well-draining soils rich in organic matter. The soil should be slightly acidic to neutral, with a pH range of 5.5 to 7.0. Heavy clay soils should be amended with organic matter to improve soil drainage and aeration.
Impatiens sylvicola is also sensitive to waterlogging and will not survive in waterlogged soils. The soil should be moist but not waterlogged, and watering should only be done when the soil feels dry to the touch.
In summary, Impatiens sylvicola requires moderate to dense shade, moderate temperatures, and well-draining soils rich in organic matter for optimal growth and development.
Cultivation Methods
Impatiens sylvicola is a shade-loving plant that grows well in well-drained, moist soil with a pH level between 6.0 and 7.0. The ideal temperature for its growth is between 10 to 30 degrees Celsius. This plant prefers humid environments and does not tolerate direct sunlight. Therefore, it is best to keep it in a partially shaded area.
Watering Needs
Irrigation is essential for Impatiens sylvicola's growth, and it requires frequent watering, especially in hot weather or dry climates. However, it is also essential to avoid overwatering, as it can cause root rot. Therefore, it's best to water the plant deeply but not so frequently, and ensure that the soil is well-draining.
Fertilization
Impatiens sylvicola requires regular fertilization to maintain its growth and blooms. The ideal time to fertilize is during the growing season which is between the spring and fall. You can use either organic or inorganic fertilizers, but it is essential to follow instructions on the package to avoid overfertilizing. It's best to dilute the fertilizer or use it sparingly to protect the plant from burning.
Pruning
Pruning is essential for maintaining the plant's shape and health. Impatiens sylvicola requires minimal pruning and mostly involves cutting back its stems to shape it. You can prune the plant after the blooming period to keep it compact and remove any dead or diseased branches. It is also essential to clean your pruning tools with alcohol to prevent the spread of diseases.
Propagation of Impatiens sylvicola
Impatiens sylvicola Burtt Davy & Greenway, commonly known as Forest balsam, is a shade-loving plant that is native to the Eastern Cape Province of South Africa. This plant is characterized by its attractive yellow flowers and green leaves. Propagation of Impatiens sylvicola can be done through seeds or vegetative methods.
Propagation by Seeds
Impatiens sylvicola seeds can be collected from mature fruits, which usually ripen three months after flowering. The seeds are small and should be collected carefully to avoid damage. Once collected, the seeds should be sown in trays filled with a well-draining medium, covered lightly with sand, and placed in a warm and shaded area. Germination will occur within 2-3 weeks, and the seedlings can be transplanted to individual pots after the first true leaves appear.
Propagation by Cuttings
Impatiens sylvicola can also be propagated through cuttings. The best time for taking cuttings is during the late summer months when the plant is actively growing. Cuttings should be taken from healthy and mature stems, about 5 cm long, and with a few leaves at the top. The cuttings should be dipped in rooting hormone powder and planted in trays filled with a well-draining rooting medium. The trays should be placed in a humid and shaded area and kept moist until the cuttings root, usually within a month or two. The rooted cuttings can then be transplanted to individual pots and grown in a greenhouse or under shade cloth until they are ready for planting.
Propagation by Division
Impatiens sylvicola can also be propagated through division. This method is best done during the early spring or autumn when the plant is not actively growing. The plant should be carefully dug up and the roots gently teased apart into individual plants. Each division should have a healthy root system and a few stems and leaves. The divisions can then be planted in individual pots or directly into the garden bed.
Disease and Pest Management for Impatiens sylvicola Burtt Davy & Greenway
Impatiens sylvicola Burtt Davy & Greenway, commonly known as the forest balsam, is a perennial plant that originates from the highland forests of Tanzania, East Africa. Despite its tolerance to different climatic conditions, the plant is susceptible to pests and diseases, which affect its growth and yield. Here are some of the common pests and diseases that affect Impatiens sylvicola and ways to manage them.
Diseases
Bacterial blight: This disease affects the leaves, stems, and flowers of the plant, causing water-soaked spots, which turn brown and lead to plant death. The spread of bacterial blight is rampant in wet conditions. To manage this, remove infected plants and destroy them. You should also avoid overhead watering and ensure proper air circulation in your nursery.
Powdery mildew: This disease affects the leaves of the plant, causing white powdery patches on the upper surface. Overhead watering, poor air-circulation, and high humidity levels favor the development of this disease. It is manageable by ensuring proper air circulation and avoiding overhead watering. You can also use fungicides to control the spread of powdery mildew.
Pests
Aphids: These pests are small insects that suck the sap from the leaves and stems, leading to plant deformation and death. Aphids are visible on the underside of the leaves and look like tiny, soft-bodied insects. You can manage aphids by using insecticidal sprays or introducing natural predators like ladybugs.
Spider mites: These pests thrive in dry and dusty environments, making Impatiens sylvicola susceptible to attack. Spider mites cause yellowing of leaves, plant wilting, and death. To manage spider mites, you should avoid using chemical pesticides, which can lead to increased resistance. Use insecticidal soaps or neem oil instead. You should also ensure proper air circulation and watering to discourage the development of spider mites.
In conclusion, to maintain a healthy Impatiens sylvicola crop, it is crucial to watch out for pests and diseases. You should ensure good gardening practices like proper watering, regular pruning, and ensuring good air circulation in your nursery. A healthy nursery environment plays an essential role in preventing the spread of pests and diseases.
