Growth Conditions of Oxalis procumbens Steud. ex A.Rich.
Oxalis procumbens Steud. ex A.Rich., also known as creeping woodsorrel, is a ground-hugging plant that belongs to the family Oxalidaceae. Understanding the growth conditions of this plant is essential for its optimum growth and development. Below are the critical factors to consider:
Light Requirements
Creeping woodsorrel thrives well in partial shade to full sun. When grown in partial shade, the plant can tolerate morning sun and afternoon shade. Exposure to direct sunlight for extended periods may cause leaf scorching. It is advisable to grow Oxalis procumbens in an open area that receives 4-6 hours of filtered sunlight per day.
Temperature
Oxalis procumbens can grow in a wide range of temperatures. The plant can tolerate a minimum temperature of 50°F (10°C) and a maximum temperature of 85°F (29°C). If the temperatures go below 50°F, the plant is likely to go dormant. Extreme heat causes the leaves to wither and scorch. The ideal temperature range for the plant growth and development is 65°F-75°F (18°C-24°C).
Soil Requirements
The growing medium for Oxalis procumbens should be well-draining and fertile. The soil should be rich in organic matter and slightly acidic with a pH range of 6-6.5. The plant does well in loamy and sandy soils. Clay soils should be avoided since they retain water, causing the roots to rot. Additionally, the plant requires consistent moisture levels to grow, but waterlogging should be avoided.
In conclusion, optimizing the growth conditions for Oxalis procumbens Steud. ex A.Rich. is essential for healthy plant growth and development. Providing adequate light, temperature, and soil requirements will ensure that the plant thrives under favorable conditions.
Cultivation of Oxalis Procumbens Steud. ex A.Rich.

The cuttings should be dipped in rooting hormone and then planted in a potting mix of peat moss and sand.
Watering Needs
The watering needs of Oxalis procumbens Steud. ex A.Rich. depend on the location and the soil type. When grown indoors, it should be watered once a week or when the top inch of the soil is dry to the touch. However, when grown outdoors, it should be watered more frequently, especially during hot and dry weather. It is essential not to overwater the plant as it can lead to root rot.
Fertilization
Adding fertilizers to the soil can help to boost the growth of Oxalis procumbens Steud. ex A.Rich. It is recommended to fertilize the plant every two weeks with a balanced, water-soluble fertilizer. The fertilizer should be diluted to half the recommended strength before application.
Pruning
