Light Requirements
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. grows best in a bright, indirect light. Direct sunlight can scorch the leaves of the plant, so it's best to keep it out of direct sunlight. Ideal light conditions are 4-6 hours of bright, indirect light a day.
Temperature Requirements
Optimal growth temperature for Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. is 60-70°F. The plant can withstand some fluctuations in temperature, but it must be kept away from frost and extreme heat. Around 60-70°F is the ideal temperature to encourage growth.
Soil Requirements
The plant prefers well-draining, moist soil with a slightly acidic pH level of 5.5-6.5. It's important to avoid overwatering, as this can lead to root rot. A mixture of equal parts peat moss, perlite, and sand is ideal for the plant's growth. Additionally, you can add a slow-release fertilizer to the soil before planting to help promote growth.
Cultivation
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. is a small, compact plant that is easy to cultivate both indoors and outdoors. It prefers well-draining soil and partial shade. The plant propagates through its bulbs, and propagation can be done through planting individual bulbs or bulbils.
Watering Needs
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. prefers to be kept slightly moist, but not waterlogged. It is best to water the plant when the top layer of soil feels dry to the touch. The plant is sensitive to overwatering, which can cause the bulbs to rot, so it is important not to water it too frequently.
Fertilization
The plant benefits from a balanced fertilizer with a ratio of 10-10-10, applied once a month during the growing season. It is best to avoid fertilizing the plant during its dormant season, as its growth is significantly reduced at that time.
Pruning
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. requires minimal pruning, with the exception of removing any dead or damaged leaves. The plant can become a bit leggy over time, and in such cases, it is best to trim the stems to encourage branching and fuller growth. However, be careful not to trim off too many stems at once, as this may shock the plant and affect its growth.
Propagation of Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh.
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. is a hardy plant that is easy to propagate. It can be propagated in various ways, including by seeds, cuttings, and offsets.
Propagation by seeds
The seeds of Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. can be sown directly into the soil. The best time to sow the seeds is during the spring or summer. The seeds should be planted in moist and well-draining soil, and they should be covered with a thin layer of soil. It is important to maintain the soil moisture until the seeds germinate, which usually takes two to four weeks.
Propagation by cuttings
The plant can also be propagated by stem cuttings. Cut a stem from the parent plant that is about 3-4 inches long and has some leaves attached to it. Dip the cut end of the stem in rooting hormone powder, and then plant it in moist and well-draining soil. Keep the soil moist and the pot in a warm and bright spot, but not in direct sunlight. In about four weeks, the cutting should develop roots and new leaves.
Propagation by offsets
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. produces offsets, also known as bulbs or corms, at the base of the plant. The offsets can be separated from the parent plant when they are about an inch in diameter. Plant the offsets in moist and well-draining soil, covering them with a thin layer of soil. Keep the soil moist and the pot in a warm and bright spot, but not in direct sunlight. The offsets should quickly develop roots and new leaves, and they can be transplanted into their permanent location in about six weeks.
Disease Management
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. is susceptible to several diseases, including:
- Botrytis blight: This disease is caused by a fungus and causes brown spots on leaves and stems. It can be managed by improving air circulation around the plant and avoiding overhead watering.
- Leaf spot: This disease is caused by a fungus and causes circular brown spots on leaves. It can be managed by removing infected leaves and improving air circulation around the plant.
- Root rot: This disease is caused by water logging and can lead to the death of the plant. It can be managed by ensuring proper drainage and avoiding overwatering.
To manage these diseases, it is important to practice good sanitation by removing infected plant materials regularly. Fungicides can also be applied as a preventative measure.
Pest Management
Oxalis convexula Jacq. var. dilatata Eckl. & Zeyh. is also susceptible to several pests, including:
- Aphids: These sap-sucking insects can be managed by spraying the plant with a strong jet of water or using insecticidal soap.
- Caterpillars: These insects can be managed by picking them off the plant and disposing of them or using insecticides.
- Spider mites: These tiny pests can be managed by improving humidity and regularly washing the plant with water.
To manage these pests, it is important to regularly inspect the plant for signs of infestation and take action promptly. Insecticides can be used as a last resort if other methods fail.
