Chamaesyce skottsbergii var. audens prefers full sunlight or partial shade as its growth depends on the light intensity. In natural habitats, it is generally found in areas with high light penetration through the canopy. Therefore, it is recommended to place this plant in a location where it can receive plenty of light.
Temperature Requirements
The optimal temperature range for the growth of Chamaesyce skottsbergii var. audens falls between 20 to 30 degrees Celsius. It can tolerate a temperature range between 5 to 35 degrees Celsius. But, for the plant's proper growth, it is recommended to maintain the temperature range suggested as an optimal level.
Soil Requirements
Chamaesyce skottsbergii var. audens prefers well-draining soil with a pH range between 6 to 7.5. It can also grow in sand, clay loam, or rocky soils. It is suggested to mix organic matter or compost to the soil before planting to enhance its texture and nutrients.
Cultivation methods
Chamaesyce skottsbergii var. audens is a semi-succulent plant that is relatively easy to grow. It prefers a well-draining soil mix, high in organic matter. It's best to plant it in a pot that has drainage holes to prevent waterlogging. Chamaesyce skottsbergii var. audens can grow in both full sun and partial shade, but the latter is more preferable.Watering needs
It's important not to overwater Chamaesyce skottsbergii var. audens as it is susceptible to root rot. The best way to water it is to wait for the soil to dry out before watering again. The frequency of watering depends on the temperature and humidity levels of the plant's environment. In summer, it requires more frequent watering, while in winter, it can be slightly reduced.Fertilization
Chamaesyce skottsbergii var. audens can benefit from regular fertilization during the growing season. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium every two weeks. Alternatively, you can apply slow-release fertilizer pellets during the growing season, which can last for several months. Avoid fertilizing the plant during the winter months when it is in a dormant state.Pruning
Pruning Chamaesyce skottsbergii var. audens is not necessary, but it can help maintain its compact shape and promote bushier growth. The best time to prune the plant is early spring before new growth begins. Use clean, sharp pruning shears to cut back the stems to a desired length. You can also remove any dead or diseased branches during the pruning process.Propagation of Chamaesyce skottsbergii var. audens
Chamaesyce skottsbergii var. audens can be propagated using various methods, including:
Seed Propagation
Seed propagation is the most common method of propagating Chamaesyce skottsbergii var. audens. The seeds should be collected from the plant when the capsules have turned brown and started to split. The collected seeds should be stored in a cool, dry place until ready for planting. Sow the seeds in trays filled with a well-draining potting mix. Keep the soil moist, but not waterlogged, until the seeds germinate, which usually takes around two weeks.
Cutting Propagation
Cutting propagation is another way of propagating Chamaesyce skottsbergii var. audens. Take 5- to 10-cm long cuttings from the plant and dip the cut ends in a rooting hormone solution. Plant the cuttings in pots filled with potting soil, keep the soil moist and place the pots in a shaded area with indirect sunlight. In about four to six weeks, the cuttings will develop roots.
Division Propagation
Division propagation is a useful method for larger Chamaesyce skottsbergii var. audens plants. Dig up the plant, taking care not to damage the roots, and divide the plant into smaller clumps. Replant the clumps in individual pots filled with potting soil, keep the soil moist, and place in a shaded area with indirect sunlight. The roots will quickly re-establish and the new plants will grow and thrive.
Disease and Pest Management for Chamaesyce skottsbergii var. audens
Chamaesyce skottsbergii var. audens is generally a hardy plant that is resistant to most diseases and pests. However, like any other plant, it is not immune to attacks from pests and infections from diseases. Below are some common diseases and pests that may affect the plant and some ways to manage them:
Diseases
Crown Rot: Crown rot is a soil-borne fungal disease that causes the roots and stem of the plant to rot. The leaves turn yellow, and the plant wilts and eventually dies. This disease is caused by excessive watering or poor drainage. To manage crown rot, ensure that the plant is grown in well-draining soil and is not overwatered.
Mildew: Mildew is a fungal disease that causes a white powdery coating on the leaves and stems of the plant. This disease is caused by high humidity and poor air circulation. To manage mildew, ensure that the plant is grown in a well-ventilated area with good air circulation. You can also apply a fungicide to control the disease.
Pests
Aphids: Aphids are small, soft-bodied insects that suck sap from the leaves of the plant. They cause the leaves to curl, wilt, and turn yellow. To manage aphids, you can spray the plant with insecticidal soap or neem oil. You can also introduce natural predators, such as ladybugs or lacewings, to control the population of aphids.
Spider Mites: Spider mites are tiny arachnids that suck sap from the leaves of the plant, causing the leaves to turn yellow and fall off. They also produce fine webbing on the plant. To manage spider mites, you can spray the plant with an acaricide or insecticidal soap. You can also introduce natural predators, such as predatory mites, to control the population of spider mites.
Mealybugs: Mealybugs are small, white, cottony insects that suck sap from the plant, causing the leaves to turn yellow and wilt. They also produce a sticky honeydew that attracts ants. To manage mealybugs, you can spray the plant with insecticidal soap or neem oil. You can also introduce natural predators, such as ladybugs, to control the population of mealybugs.
By practicing good cultural practices and using natural pest control methods, you can manage and prevent most diseases and pest infestations on Chamaesyce skottsbergii var. audens, ensuring the health and vitality of your plant.
