Light Requirements
The Callilepis hispida DC. plant prefers bright, indirect light. It can tolerate some direct sunlight but should be protected from intense heat and radiation as it can cause damage to the plant. The plant can also grow under artificial light sources like fluorescent bulbs or LED grow lights.
Temperature Requirements
The Callilepis hispida DC. plant grows best in warm temperatures ranging between 20°C to 30°C (68°F to 86°F). The plant can tolerate cooler temperatures but should not be exposed to frost or cold drafts. When temperatures drop below 10°C (50°F), the plant may start to experience stunted growth, yellowing of the leaves, and even death.
Soil Requirements
The Callilepis hispida DC. plant thrives in well-draining, fertile soils that are rich in organic matter. The ideal soil should be slightly acidic, with a pH range of 5.5 to 6.5. The plant can tolerate a wide range of soil compositions, including sandy, loamy, or clay soils. However, the soil should not be waterlogged as it can cause root rot, which can kill the plant.
Cultivation methods for Callilepis hispida DC.
Callilepis hispida DC. is a hardy plant that can adapt to a wide range of growing conditions, but it does have some preferred factors.
The ideal soil should be well-draining, slightly acidic to neutral, and rich in organic matter. The plant requires a sunny to partially shady spot, out of harsh winds. If grown in a colder climate, it can be grown in a greenhouse.
It is recommended to grow Callilepis hispida DC. from seeds in the spring. The small plants should be kept well watered. They can be transplanted to a permanent spot after 1-2 months.
Watering needs for Callilepis hispida DC.
Callilepis hispida DC. requires moderate watering, with enough time in between waterings to let the soil dry out slightly. The plant responds well to extra water during the hot summer months, but too much water will lead to root rot. In general, it is best to keep the soil slightly moist, but not waterlogged.
During the winter, water only enough to keep the soil from completely drying out. Overwatering in winter can lead to cold damage as well as root rot.
Fertilization for Callilepis hispida DC.
Callilepis hispida DC. benefits from fertilization during the growing season. A balanced 10-10-10 fertilizer can be applied every 4-6 weeks. Dilute the fertilizer to half the recommended strength, and apply it during the watering process.
The plant also responds well to compost, so a layer of compost can be added to the soil's surface and gently worked in around the roots. Avoid contact between the compost and plant stems to prevent rot.
Pruning for Callilepis hispida DC.
Callilepis hispida DC. requires little pruning, but dead or diseased stems can be removed during the growing season. To prevent blooming, the plant can also be pruned in the late fall or early winter. Remove any broken or crossing branches and remove no more than ? of the total plant's size. Prune to shape the plant if needed.
It is recommended to wear gloves while pruning, as the plant can cause contact dermatitis in some people. Disinfect the pruning tools before and after pruning to prevent spreading diseases and pests.
Propagation of Callilepis hispida DC.
Callilepis hispida DC. is commonly known as hairy stem chrysanthemum and belongs to the family Asteraceae. The plant is native to China and is popularly grown as an ornamental plant due to its attractive flowers.
The propagation of Callilepis hispida DC. can be done by the following methods:
Seed Propagation
Callilepis hispida DC. can be propagated by seeds. The seeds can be sown in a well-drained soil mix, and kept in a warm and bright location. The seeds typically germinate in 1-2 weeks, and the seedlings can be transplanted to individual pots once they develop their first true leaves.
It is important to keep the soil moist but not waterlogged, and to avoid over-fertilization during the seedling stage.
Stem Cuttings Propagation
Another propagation method for Callilepis hispida DC. is through stem cuttings. The cuttings can be obtained from the mature plants and should be at least 10cm long with 2-3 nodes. The bottom of the cutting should be dipped in a rooting hormone and inserted in a well-draining soil mix. The cuttings should be kept moist and in a warm location with bright, indirect sunlight. The roots should start forming in 2-3 weeks, and the newly rooted plants can be transplanted once they are established.
Division Propagation
Callilepis hispida DC. can also be propagated through division. The plant should be carefully divided into smaller clumps, ensuring that each clump has an adequate amount of roots. The divided plants can be planted in individual pots or in the ground in well-draining soil mix and kept moist until established.
It is important to note that Callilepis hispida DC. prefers warm temperatures and moderate humidity, and should be protected from frost and extreme cold weather. Additionally, the plant likes well-draining soil, and should be watered when the top inch of soil is dry.
Disease Management for Callilepis hispida DC.
Callilepis hispida DC. is a flowering plant that can be prone to several diseases. Here are some common diseases that may affect Callilepis hispida DC. and ways to manage them:
Powdery Mildew
Powdery mildew is a fungal disease that can be recognized by the white powdery substance that appears on leaves, stems, and flowers of the plant. It can be controlled by ensuring good air circulation around the plant and keeping its leaves dry by watering at the base. Fungicide sprays may also help control the disease.
Leaf Spot
Leaf spot is a fungal disease that affects plant leaves and causes spots to develop on them. These spots can range from light brown to black and can eventually result in the leaves falling off. To manage leaf spot, practice good sanitation by removing and destroying any affected leaves or plant material. Fungicides may also be used to prevent further spread of the disease.
Pest Management for Callilepis hispida DC.
Several pests may infest Callilepis hispida DC. Here are some common pests that may affect Callilepis hispida DC. and ways to manage them:
Aphids
Aphids are small, soft-bodied insects that can damage the plant by sucking the sap from its leaves and stems. To manage aphids, prune the affected parts and control their population through natural predators like ladybugs or by using insecticidal soaps or oils.
Spider Mites
Spider mites are tiny pests that feed on the sap of Callilepis hispida DC. and can cause significant damage to the plant. They can be controlled by washing the plant with a strong stream of water or by using insecticidal soaps or oils.
Caterpillars
Caterpillars are the larvae of moths or butterflies and can feed on the leaves and flowers of Callilepis hispida DC., often resulting in significant damage. To manage caterpillars, pick them off by hand and drop them in soapy water or use Bacillus thuringiensis (BT) insecticide.
