Overview
Oxalis involuta T.M.Salter, also known as the curly-frywoodsorrel or curly woodsorrel, is a small flowering plant that belongs to the Oxalidaceae family. This plant is native to South Africa and is commonly found in the Western and Eastern Cape regions, growing in moist soils near streams or in shaded areas within forests.
Appearance
This plant typically grows up to 12 cm tall and has thin, wiry stems that bear yellow flowers. Its leaves are made up of three leaflets and have a unique curly or twisted appearance, which gives it its common name of curly-fry woodsorrel.
Uses
Oxalis involuta T.M.Salter is not commonly used for medicinal or culinary purposes, but it is often grown as an ornamental plant for its unique and attractive appearance. It can also serve as a ground cover in shaded areas of gardens or parks.
However, caution should be taken when handling this plant as it contains oxalic acid, which can be toxic to humans and pets if ingested in large quantities.
Cultivation
Oxalis involuta T.M.Salter can be propagated through seeds or cuttings and prefers moist, well-drained soils in partially shaded areas. It can also tolerate full sun but may require more frequent watering in such conditions. Proper care and maintenance, including regular pruning to encourage bushier growth, can help ensure healthy and vigorous growth of this plant.
Overall, Oxalis involuta T.M.Salter is a unique and visually appealing plant that can add a touch of interest to any shaded garden or landscape.
Light Requirements
Oxalis involuta T.M.Salter prefers partial to full shade conditions. It cannot withstand direct sunlight for extended periods, especially during the hottest parts of the day. Therefore, it should be grown indoors or under a shade cloth if planted outside.
Temperature Requirements
Oxalis involuta T.M.Salter is native to South Africa, where the temperatures range from 46°F to 82°F (8°C to 28°C). Therefore, it grows best under similar climatic conditions. It cannot endure temperatures below 40°F (4.4°C) or above 90°F (32.2°C). It is essential to protect the plant from extreme cold or heat to avoid stunting its growth or causing it to wither.
Soil Requirements
The soil should be porous, well-draining, and rich in organic matter content. The pH levels should range between 5.5 and 7.5, and the soil should be moderately fertile. A mixture of topsoil, peat moss, and sand in equal measures, or perlite, vermiculite, and coco coir, is an excellent base for cultivation. It is also possible to add slow-release fertilizers or compost to enhance soil fertility, as the plant requires a nutrient-rich environment.
Cultivation Methods
Oxalis involuta is a perennial plant that has a low growing habit and semi-evergreen foliage. This plant prefers well-drained soil and needs to be grown in full sunlight to partial shade. It can be grown outdoors in USDA plant hardiness zones 8-11 or indoors as a houseplant. To propagate this plant, one can either use seeds or rhizome division.
Watering Needs
The watering needs of Oxalis involuta are moderate. This plant prefers to be kept moist but not waterlogged. It is important to avoid overwatering as this can lead to root rot. On the other hand, underwatering can cause the plant to wilt.
Fertilization
Fertilization is crucial for the growth and health of Oxalis involuta. This plant should be fertilized during the growing season with a balanced fertilizer. It is recommended to fertilize once a month using a low-strength liquid fertilizer. As the plant enters dormancy during the winter, the fertilizer should be stopped.
Pruning
Pruning should be done to keep Oxalis involuta in shape and promote bushier growth. It is best to prune the plant after it has finished flowering. This plant can be pruned by removing the spent flowers and trimming the stems to a desired length. It is important to avoid pruning too much as this can damage the plant.
Propagation of Oxalis involuta T.M.Salter
Oxalis involuta T.M.Salter, also known as the Volute Yellow Wood Sorrel, is a plant species that belongs to the non-succulent families of the Oxalidaceae. Propagation of this plant can be done in several ways:
Seed Propagation
The easiest and most common way to propagate O. involuta is through seeds. The seeds are small, round, and dark-brown in color. To start the germination process, sow the seeds in a moist potting mix, making sure that the seeds are not too deep (no more than 1/4 inch). Keep the potting mix moist and place it in a bright, warm spot, but away from direct sunlight. The seeds should germinate within two weeks.
Division
O. involuta can also be propagated through division. This method involves dividing the plant into smaller parts that include the stem and the roots. Carefully remove the plant from the soil and gently separate the root clusters into smaller sections. Replant the sections into their own containers and keep them well-watered until they establish themselves.
Cutting
Another way to propagate O. involuta is through cuttings. Take a stem cutting from the plant that is at least 2-3 inches long, ensuring that it has at least 2-3 leaves. Remove the bottom leaves and dip the cut end in rooting hormone. Plant the cutting in a small container filled with potting mix and keep it moist. The cutting should start to grow roots within 3-4 weeks.
Overall, O. involuta is relatively easy to propagate and can quickly grow into new plants. Seed propagation, division, and cutting methods are all effective ways to add this beautiful plant to your collection.
Disease and Pest Management for Oxalis involuta T.M.Salter
Oxalis involuta T.M.Salter, commonly known as the blue oxalis, is a delicate plant that is susceptible to a range of diseases and pests. To keep the plant healthy, it is essential to identify and manage these problems promptly. Here are some common diseases and pests that might affect the plant:
Diseases
Rust: Rust is a fungal disease that causes orange or brown spots on the leaves. It can spread quickly and cause severe damage to the plant. To manage rust, remove the infected leaves and treat the plant with a fungicide according to the instructions on the label.
Leaf spot: Leaf spot is another fungal disease that causes small, brown spots on the leaves. It can also spread quickly and cause significant damage. To manage leaf spot, remove the infected leaves and treat the plant with a fungicide. Ensure that the plant is not overcrowded, as this can promote the spread of the disease.
Pythium rot: Pythium rot is a fungal disease that affects the roots of the plant. It causes the roots to rot, leading to wilting and death. To manage Pythium rot, avoid overwatering the plant and ensure that the soil is well-draining. Remove any infected plants promptly and treat the remaining plants with a fungicide.
Pests
Spider mites: Spider mites are tiny pests that can cause extensive damage to the plant. They feed on the sap of the plant, causing the leaves to turn yellow and dry out. To manage spider mites, wipe the leaves with a damp cloth regularly, and treat the plant with an insecticide according to the instructions on the label.
Aphids: Aphids are another pest that can damage the plant. They feed on the sap of the plant, weakening it and causing the leaves to curl and distort. To manage aphids, spray the plant with a mixture of water and dish soap. Alternatively, use an insecticide according to the instructions on the label.
Whiteflies: Whiteflies are small, white insects that can suck the sap from the leaves of the plant. They can cause yellowing and wilting of the leaves. To manage whiteflies, remove any infected leaves promptly and treat the plant with an insecticide according to the instructions on the label.
Regular monitoring of the plant for signs of disease or pests is the key to managing these problems. By taking quick action, you can help to keep your Oxalis involuta T.M.Salter healthy and happy.
