Light Requirements
Becium obovatum auct. thrives in areas exposed to full sun or partial shade. It can tolerate some shade, but direct sunlight is essential for healthy growth. When planting this species, it's crucial to choose a location that gets at least six hours of sunlight a day. Insufficient sunlight may cause the plant to become spindly and weak.
Temperature Requirements
Becium obovatum auct. requires warm temperatures to grow. It grows best in areas with an average daytime temperature of around 20°C (68°F) and a nighttime temperature of around 10°C (50°F). The plant can tolerate temperatures as high as 40°C (104°F) during the day and as low as 5°C (41°F) at night. Extreme temperature fluctuations can harm the plant and should be avoided.
Soil Requirements
Becium obovatum auct. grows well in well-drained soils of medium texture. It thrives in soils that are rich in organic matter, with a pH level between 6 and 7.5. The plant requires regular watering to grow and flourish, but it doesn't do well in waterlogged soils. If the soil is too compacted, add some sand, pumice, or perlite to increase the drainage rate. Regular testing of the soil's nutrient levels is essential to maintain the plant's health.
Cultivation Methods
Becium obovatum auct. can be grown in well-drained soil under full sun or partial shade. It can be propagated through seeds or stem cuttings, and planting should be done during the rainy season. The plant prefers a warm and humid climate, so it should be grown in regions with a temperature range of 20-28°C.
Watering Needs
Becium obovatum auct. requires regular watering during the growing season and less frequent watering during the dormant season. The plant prefers moist but not waterlogged soil, so it is important to ensure proper drainage. Overwatering should be avoided, as it can lead to root rot.
Fertilization
Becium obovatum auct. benefits from regular fertilizer application, which should be done every three to four months during the growing season. A balanced fertilizer with a ratio of 10-10-10 is recommended. Over-fertilization should be avoided, as it can lead to excessive growth and reduced plant health.
Pruning
Becium obovatum auct. should be pruned regularly to promote bushier growth and increase flowering. The best time for pruning is after the plant has finished flowering. Deadheading should also be done regularly to remove spent flowers and encourage new growth. It is important to use clean and sharp tools when pruning, to prevent the spread of diseases.
Propagation of Becium obovatum auct.
Becium obovatum auct. is a perennial herb that can be propagated through various methods. Here are some propagation methods:
From Seeds
Becium obovatum auct. can be propagated from seeds. The best time to sow the seeds is in spring when the temperature is around 21°C. The seeds should be sown in moist soil and at a depth of 1 cm. The soil should be kept moist until the seedlings emerge.
From Softwood Cuttings
Becium obovatum auct. can also be propagated from softwood cuttings. Softwood cuttings are taken from the new growth in spring or early summer. The cuttings should be around 5-10 cm long and should be taken from the tips of the stems. The cuttings should be dipped in rooting hormone and then planted in moist soil. They should be placed in a warm and humid environment until they start rooting.
From Division
Becium obovatum auct. can be propagated through division as well. The best time to divide the plant is in spring when the new growth starts to emerge. The plant should be dug up carefully, and the root ball should be separated into smaller sections. Each section should have some roots and shoots. The sections can then be replanted in well-drained soil.
Disease Management
Becium obovatum auct. is a resilient plant species that can withstand various weather conditions and illnesses. However, there are some diseases that may affect the plant, such as:
- Root Rot - caused by fungi in the soil, which leads to the death of the roots.
- Leaf Spot - characterized by yellowing, wilting or black spots on leaves. This is caused by a fungus.
- Powdery Mildew - appears as a white powdery coating on leaves caused by fungal spores.
To manage these diseases, it is important to maintain proper plant hygiene. Keep the plant dry by watering only when the top inch of soil is dry. Avoid overhead watering, which can lead to fungal growth. Remove and dispose of infected plant debris, and avoid crowding plants. In severe cases, using a fungicide can be effective, but it is best to consult with a professional before doing so.
Pest Management
B. obovatum auct. is generally pest-resistant, but may occasionally fall prey to some insects, such as:
- Spider mites - tiny pests that suck juices from the plant, causing leaves to turn yellow and eventually fall off.
- Mealybugs - appear as soft, cottony patches on the plant surface and can weaken and deform the plant.
- Aphids - small insects that suck sap from the plant, causing distorted leaves and stunted growth.
To manage these pests, regularly inspect the plant and take action at the first sign of infestation. Isolate the infected plant to prevent the spread of the pests. Use insecticidal soap or oil sprays to deter these pests from attaching to the plant. For severe cases, professional assistance may be necessary.
