Cultivation
Oxalis dentata Jacq., commonly known as the toothed wood sorrel, is a perennial plant native to South America. It is easy to cultivate and care for, making it a popular choice for gardeners. The plant prefers well-draining soil, rich in organic matter and slightly acidic to neutral pH.
The best time to plant Oxalis dentata Jacq. is during the spring or fall when the weather is mild. The plant can be propagated through division, seeds, and stem cuttings. When planting, ensure that the crown of the plant sits at the soil surface and water thoroughly.
Watering Needs
Oxalis dentata Jacq. requires consistent moisture but is sensitive to overwatering. The soil should be slightly moist, but never waterlogged. It is recommended to water the plant when the top inch of soil feels dry to the touch, typically once or twice a week.
During the winter months, it is crucial to reduce watering to prevent root rot and allow the plant to enter a state of dormancy.
Fertilization
To promote growth and flowering, it is recommended to fertilize Oxalis dentata Jacq. every four to six weeks using a balanced fertilizer. During the winter months, fertilization can be reduced to once every two months.
Avoid over-fertilizing, as this can lead to excessive foliage growth and reduced flowering.
Pruning
Pruning is not required for Oxalis dentata Jacq., but it can help to maintain a compact and bushy appearance. Deadheading spent blooms will encourage the plant to produce more flowers. It is also recommended to remove any yellow or damaged leaves to improve the plant's overall health.
The best time to prune is during the springtime before new growth begins. Sterilize pruning shears before and after use to prevent the spread of disease.
