The leaves are about 2-3 inches in length, arranged in opposite pairs. The plant forms a sprawling mat-like structure and can grow up to 10cm in height and 30cm in spread. The flowering occurs in midsummer to mid-autumn with a cluster of small, white or pinkish flowers at the end of the stem.
Uses
Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern. is a popular ornamental plant, especially for rock gardens, ground covers, or borders. It can also be grown in containers and used as an indoor plant. The plant is low maintenance, drought-tolerant, and can thrive in full sun or partial shade. It is also considered a great option for soil erosion control. Furthermore, in some African countries, it has medicinal properties and is used to treat skin ailments and diarrhea.
Cultivation
Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern. is an easy plant to grow and propagate. It thrives in well-draining soil and requires a moderate amount of water during the growing season. However, it is essential to avoid overwatering as it can cause root rot. The plant is propagated through seeds or stem cuttings during the active growth period. For maximum growth, it is recommended to grow the plant in full sun, but it can also survive in partial shade.
Light Requirements
Crassula schimperi subsp. phyturus requires bright, indirect sunlight for optimal growth. Excessive exposure to direct sunlight can cause sunburn and damage the leaves. It is recommended to place the plant near a south or east-facing window that receives partial sunlight. A lack of sunlight can result in stunted growth and leggy shoots.
Temperature Requirements
This plant prefers moderate to warm temperatures. Ideal daytime temperatures range between 70-80°F (21-27°C) with nighttime temperatures dropping to 50-60°F (10-16°C). Sudden temperature fluctuations can cause stress and damage the plant. Exposure to temperatures below 40°F (4°C) can be fatal.
Soil Requirements
Crassula schimperi subsp. phyturus requires well-draining soil that retains moisture. A soil mix that includes a combination of peat moss, vermiculite, and perlite creates a suitable growth environment for the plant. The soil should be slightly acidic (pH 6.0-7.0). It is important to avoid overwatering as it can lead to root rot.
Cultivation methods
Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern. is a succulent plant that prefers well-draining soil and full sun. It can be grown outdoors in USDA hardiness zones 9-11 or indoors in a bright, sunny location. When planting, make sure to leave enough space between each plant to allow for growth.Watering needs
Watering frequency for Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern. can vary based on the location and season. In general, it is best to wait until the soil is completely dry before watering again. Overwatering can lead to root rot and other issues. During the winter months, reduce watering to avoid the plant becoming too wet and cold.Fertilization
Fertilization is not necessary for Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern. However, if you prefer, you can use a balanced fertilizer once a month during the growing season. This will help promote healthy growth and flowering, but be sure to follow the package instructions carefully.Pruning
Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern. typically does not require pruning. However, if your plant becomes too leggy or begins to look unruly, you can trim back the stems with a pair of sharp, clean scissors. With this species, it is best to prune during its active growth season when it is more likely to recover quickly. Additionally, any leaves that become yellow or brown can be removed at any time to improve the plant's overall appearance.Propagation of Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern.
Propagation of Crassula schimperi Fisch. & C.A.Mey. subsp. phyturus (Mildbr.) R.Fern. is relatively easy and can be achieved through various methods, including:
Leaf Cutting Propagation
One of the simplest methods of propagating Crassula schimperi subsp. phyturus is through leaf cutting. Take a healthy leaf and carefully remove it from the stem. Make sure that you keep the base intact. Place the leaf on a dry surface and allow it to form a callus for a few days. Once the callus has formed, you can plant the leaf in well-draining soil and water sparingly. Over time, the leaf will grow roots and form a new plant.
Stem Cutting Propagation
Stem cutting is another method of propagating Crassula schimperi subsp. phyturus. Take a healthy stem cutting and allow it to dry and form a callus for a few days. Once the callus has formed, plant the cutting in a well-draining soil mixture. Water the cutting sparingly and avoid fertilizing until the plant has established roots.
Division Propagation
Division propagation involves separating a mature plant into smaller sections and replanting them. This method is useful for mature plants with multiple stems growing from a single rootstock. To propagate through division, carefully separate the stems from the rootstock and plant them in well-draining soil mixture. Ensure that each section has enough roots to support itself.
Conclusion
Propagation of Crassula schimperi subsp. phyturus is relatively easy and can be achieved through leaf cutting, stem cutting, or division methods. With a little care and patience, you can easily propagate new plants from a mature Crassula schimperi subsp. phyturus plant.
Disease Management
Crassula schimperi subsp. phyturus is highly resistant to diseases, but occasionally, it may suffer fungal diseases such as stem and root rot due to overwatering and poor drainage. When the soil is too wet for too long, the roots are unable to breathe and eventually rot, affecting the entire plant. The symptoms of fungal disease include wilting, yellowing or browning leaves, and a soft and spongy stem. To prevent the disease, proper watering practices and well-draining soil are essential. If the diseases occur, remove the affected plant, and repot the remaining healthy ones. Use a fungicide to prevent further contamination.
Pest Management
The Crassula schimperi subsp. phyturus is prone to mealybugs, spider mites, and scale insects. These bugs suck the sap from leaves and stems, causing the plant to weaken and eventually die. They also excrete a honeydew substance, which attracts sooty mold, further damaging the plant. A proactive approach to pest control helps contain an infestation before it gets out of hand. Checking the plant regularly for signs of infestation such as discolored leaves and webbing can be helpful. Remove the infected parts of the plant and isolate it to prevent the spread of pests. Use neem oil, insecticidal soap, or rubbing alcohol to control the infestation. Introduce natural predators such as ladybugs or lacewings can be useful in controlling the pest population.
