Light Requirements
Aulacocalyx pallens, like many other tropical plants, requires high levels of light for healthy growth. It thrives in bright, indirect sunlight and may become sickly or stunted if kept in low light conditions. Therefore, it is best to place this plant near a window with eastern or western exposure. It is important to avoid direct sunlight, especially during the hot afternoons, as it can cause leaf scorch.
Temperature Requirements
This plant species requires warm temperatures and does not tolerate cold weather well. The ideal temperature range for Aulacocalyx pallens is between 21°C to 28°C (70°F to 82°F). Maintain a consistent temperature and avoid sudden fluctuations, as it can cause stress and harm to the plant. During the winter, ensure that the plant is kept away from any cold drafts or windows.
Soil Requirements
The soil for Aulacocalyx pallens should be kept evenly moist but not waterlogged. Well-draining soil with good aeration is ideal. A mixture of peat moss and perlite, or commercial potting soil, is suitable for this plant species. It is important to ensure good drainage to avoid root rot, which can be caused by overly wet soil.
In order to maintain healthy growth, this plant requires regular fertilizer applications during its growing season. A balanced, slow-release fertilizer with equal portions of nitrogen, phosphorus, and potassium is recommended. Feed the plant every four weeks during spring and summer, and reduce feeding during the winter months when it is less active.
Cultivation of Aulacocalyx pallens
Aulacocalyx pallens is native to Central Africa and is commonly cultivated as an ornamental plant. It is a slow-growing plant that thrives in well-draining soils with a slightly acidic pH.
Watering Needs
The plant's watering needs should be moderate to avoid waterlogging the soil. You must let the soil dry out completely between watering to prevent overwatering and root rot. It is advisable to use a watering can or a hose to supply water to the soil slowly.
Fertilization
Aulacocalyx pallens requires regular fertilization to thrive. You can use a soluble fertilizer that is well balanced in nutrients. Fertilize the plant once a month during the growing season, from spring to fall. Reduce fertilizer application to once every two months during winter when the plant is dormant.
Pruning
Pruning helps maintain the plant's shape and encourage new growth. You should prune Aulacocalyx pallens in early spring before new growth appears. Prune any dead, damaged, or diseased stems and remove any weak or spindly stems to improve air circulation and light penetration. Also, cut back the plant to control its size and promote bushiness.
Propagation of Aulacocalyx pallens (Hiern) Bridson & E.Figueiredo
Aulacocalyx pallens, commonly known as the "soft pink Aulacocalyx" is a species of plant in the family Gesneriaceae. It is native to tropical regions of Africa and can be propagated through various methods.
Seed Propagation
Propagation by seeds is possible, but it is not the most efficient method. The seeds require moisture and warmth to germinate, so sowing them in a seed tray filled with well-draining soil is recommended. The tray should be covered to maintain moisture levels, and the temperature should be kept around 20-24°C. The seedlings can be transplanted to pots once they have grown two to three sets of true leaves.
Cutting Propagation
The easiest and most successful method of propagating Aulacocalyx pallens is by stem cuttings. With a sharp, sterile blade, cut a healthy stem with at least three nodes and remove the lower leaves. Dipping the cutting in rooting hormone is optional but may increase the success rate. Place the cutting in a pot with well-draining soil and keep it moist but not waterlogged. Covering the pot with a clear plastic bag can help maintain high humidity levels, which can increase the chances of successful rooting. Avoid direct sunlight and keep the pot in a warm and bright area.
Division Propagation
Aulacocalyx pallens can also be propagated by division. This method involves separating the plant into smaller portions, each with its own roots. This can be done when repotting an established plant or by carefully digging up the plant and separating the different parts. Each portion should have enough roots to support the plant's growth. The divided plants should be potted in well-draining soil and kept moist but not waterlogged.
Disease Management
Aulacocalyx pallens (Hiern) Bridson & E.Figueiredo is susceptible to several diseases. Below are the common ones and ways to manage them:
Leaf Spot
Leaf spot is a fungal disease that appears as brown or black spots on the leaves. To manage it, remove the affected leaves, apply fungicides, and avoid watering the leaves.
Root Rot
Root rot is a fungal disease that affects the roots, causing them to rot. This disease occurs when the soil is too wet. To manage it, reduce watering and apply fungicides.
Mildew
Mildew is a fungal disease that appears as a whitish powder on the leaves. To manage it, remove the affected leaves, apply fungicides, and increase the ventilation around the plant.
Pest Management
Aulacocalyx pallens (Hiern) Bridson & E.Figueiredo are also prone to pest attack. Below are the common ones and ways to manage them:
Spider Mites
Spider mites are tiny pests that suck the sap from the leaves, causing yellow spots. To manage them, spray the leaves with water or insecticidal soap. Also, increase the humidity around the plant.
Scale Insects
Scale insects are tiny pests that attach themselves to the leaves, causing yellow spots. To manage them, remove them by hand, apply insecticides, and avoid overcrowding of the plant.
Mealybugs
Mealybugs are tiny white pests that suck the sap from the leaves, causing yellow spots. To manage them, remove them by hand, apply insecticides, and increase the ventilation around the plant.
