Oxalis radicosa A. Rich. thrives in bright light conditions, ranging from partial shade to full sun exposure. However, direct sunlight exposure for extended periods may cause leaf wilting and damage to the plant.
Temperature Requirements
The ideal temperature range for Oxalis radicosa A. Rich. growth is between 15°C to 25°C. The plant can tolerate a wide range of temperatures and can sustain temperatures as low as 5°C and as high as 35°C momentarily but not for an extended time, which may lead to plant death.
Soil Requirements
The plant requires well-draining soil that's rich in organic matter. Oxalis radicosa A. Rich. prefers slightly acidic to neutral soils, with pH levels ranging between 5.5 to 7.0. Sandy loam soils with moderate water retention are ideal for the plant's growth and development. Overwatering can trigger root rot and decrease plant growth and vitality levels, causing the leaf's dropping.
Cultivation of Oxalis radicosa A. Rich.
The cultivation of Oxalis radicosa A. Rich. requires a good amount of sunlight, and the plant can easily tolerate heat. It can be grown both indoors and outdoors.
The plant prefers well-draining soil, which is not too heavy. A potting mix rich in organic matter can also be used to wither indoor or outdoor plants. The pH level of the soil must be between 5.5 to 6.5 for optimal growth.
The seeds should be sowed in well-draining soil and kept moist until germination. It germinates quickly, and the seedlings can be thinned once they have two or three leaves.
Watering Needs of Oxalis radicosa A. Rich.
Oxalis radicosa A. Rich. requires regular watering to maintain healthy growth. It is watered when the top one inch of soil feels dry. However, it should not be left in standing water, which can cause root rot.
During the winter, watering should be reduced to avoid waterlogging. It is advised that one should water well in the morning, allowing enough time for the foliage to dry before nightfall.
Fertilization of Oxalis radicosa A. Rich.
The plant requires regular fertilizing during the growing season. A balanced liquid fertilizer or slow-release granular fertilizer can be used.
The recommended feeding routine involves fertilizing every two weeks during the growing season, spring to fall. New growth should be monitored, and fertilization adjusted accordingly.
Pruning of Oxalis radicosa A. Rich.
Oxalis radicosa A. Rich. does not require regular pruning. However, it is advised to remove dead or damaged leaves to maintain the plant's appearance.
If the plant becomes too leggy, it can be trimmed to promote bushiness. The trimming should be done during the growing season, and the plant should be monitored to avoid over-pruning.
Propagation of Oxalis radicosa A. Rich.
Oxalis radicosa A. Rich., commonly known as redwood sorrel, is a beautiful herbaceous plant with clover-shaped leaves. The plant is native to lower mountains of California and Baja California. For ornamental purposes, the plant can be propagated by two methods: division or seeds.
Propagation by Division
The easiest and most successful method of propagating Oxalis radicosa A. Rich. is by division. The plant grows a mass of small, shallow rhizomes just below the soil surface that can be easily divided by hand. The division should be done in late winter or early spring before new growth appears. The following steps should be taken:
- Carefully dig up the plant and remove excess soil to expose the rhizomes.
- Using a sharp, sterilized knife, cut the rhizomes into small sections (each section should have at least one healthy bud).
- Plant the divided rhizomes in a pot filled with equal parts peat moss and sand.
- Water the soil thoroughly and keep it consistently moist but not waterlogged.
- Place the pot in a shaded area with a temperature of 60-70°F and humidity of 80-90%.
- The new plants will begin to grow in a few days. Once they become established, they can be transplanted into the desired location.
Propagation by Seeds
Propagation of Oxalis radicosa A. Rich. by seeds is possible but may not be as reliable as division. The following steps should be taken:
- Collect ripe seeds from the plant in late summer or early fall.
- Soak the seeds in warm water for 12-24 hours to soften the seed coat.
- Sow the seeds in a pot filled with moist, well-draining soil.
- Lightly cover the seeds with a thin layer of soil.
- Water the soil thoroughly and keep it consistently moist but not waterlogged.
- Place the pot in a shaded area with a temperature of 60-70°F and humidity of 80-90%.
- The seedlings will begin to appear in two to three weeks. Once they become established, they can be transplanted into the desired location.
Disease Management:
Oxalis radicosa A. Rich. is susceptible to various diseases that can affect the plant's health and appearance. Common diseases that can affect the plant include fungal diseases like powdery mildew and leaf spots. These diseases can be managed through different measures, including cultural, mechanical, and chemical control methods.
Cultural Control:
Cultural control methods involve creating unfavorable conditions for the disease incidence and development. These may include planting disease-resistant varieties, practicing crop rotation, and avoiding waterlogging, which favors the growth of fungal pathogens. Mulching the soil around the plant's base can also help prevent water splashing that can spread fungal spores.
Mechanical Control:
Mechanical methods, such as pruning infected parts of the plant, can help reduce the spread of the disease. If the disease is widespread, uprooting the plant can help prevent it from spreading to healthy plants.
Chemical Control:
Chemical pesticides can also be used to manage diseases where cultural and mechanical methods may not be effective. It is best to use chemicals as a last resort and follow product label instructions carefully to avoid harming the plant or the environment.
Pest Management:
Oxalis radicosa A. Rich. is prone to infestation by different pests that can affect its growth and productivity. Common pests that can affect the plant include spider mites, aphids, and mealybugs.
Cultural Control:
Cultural control methods can help prevent and reduce pest infestation. These include proper plant spacing, crop rotation, and removing plant debris, which can harbor pests and their eggs. Regularly inspecting plants for pests can also help detect infestations early and prevent them from spreading.
Mechanical Control:
Mechanical control involves physically removing the pests by handpicking or using traps. Regularly spraying water on the plant's foliage can help dislodge pests like spider mites and aphids.
Chemical Control:
Chemical insecticides can also be used to manage pest infestation when cultural and mechanical methods are not effective. However, it is advisable to use chemicals as a last resort and follow the product label instructions carefully to avoid harming the plant, non-target organisms, and the environment.
