Origin and Common Names
Oxalis interior (Small) Fedde, commonly known as Small Wood Sorrel or Interior Yellow Wood Sorrel, is a member of the Oxalidaceae family native to North America. It can be found in various regions such as the Appalachian Mountains, New England, and the Midwest.
Appearance
Small Wood Sorrel is a small plant, with an average height of 7.5-10 cm (3-4 inches). It has a fibrous root system and a stem that is smooth and erect, with sparse hair on the upper part. The leaves are trifoliate, which means they have three heart-shaped leaflets joined at the base, forming a clover-like appearance. The leaflets have a bright yellow-green color and can range from 1-3 cm (0.5-1.2 inches) in length.
The delicate flowers bloom in early summer, and each stem produces a single flower with five pinkish-white petals. The petals have darker pink veins on them. Once the flowers have been pollinated, they give way to small seed capsules.
Uses
Small Wood Sorrel is often grown as an ornamental plant in gardens and rockeries. It is praised for its attractive foliage and dainty flowers that add a pop of color to any setting. The leaves of the plant are edible and known for their tangy flavor. They can be added to salads or used as a garnish. However, it should be noted that the plant contains oxalic acid, which can upset the stomach if consumed in large quantities.
Small Wood Sorrel also has medicinal properties and has been used traditionally to treat a range of conditions such as gastrointestinal issues, coughs, and fever. The plant contains flavonoids and tannins that possess anti-inflammatory and antimicrobial properties.
Light Requirements
Oxalis interior thrives in bright, indirect light. Direct sunlight for extended periods may burn the leaves. Place the plant near a window that receives bright, indirect light for best growth. Insufficient light can cause the plant to become leggy, with long stems and sparse foliage.
Temperature Requirements
Oxalis interior prefers warm temperatures between 60 to 75°F (16 to 24°C). Temperatures below 50°F (10°C) can cause the leaves to wilt. Avoid placing the plant near drafts or cold windows as sudden temperature fluctuations can harm the plant.
Soil Requirements
Select a well-draining potting mix that retains moisture but does not become soggy. A mix containing peat moss, perlite, and vermiculite provides an ideal growing medium for Oxalis interior. The plant prefers slightly acidic soil with a pH between 5.5 and 6.5. Avoid using heavy potting soil that can cause root rot and stunted growth.
Cultivation
Oxalis interior (Small) Fedde, commonly referred to as "wood sorrel," is a perennial herb that thrives in moist, shady areas and prefers well-draining soil. It is easy to cultivate in a garden bed or container.
It is best to propagate wood sorrel with its root ball intact. When transplanting, ensure that the roots are not damaged. It will quickly establish itself, and you can propagate it by dividing the plant roots every few years.
Watering Needs
Wood sorrel prefers consistently moist soil. Water the plant thoroughly and frequently when planting it in the garden bed or container. In hotter climates, watering should be done at least twice a week. In cooler climates or during the winter dormant period, watering can be reduced.
Avoid overwatering and don't allow the plant to sit in standing water, as this encourages root rot.
Fertilization
Wood sorrel doesn't require much fertilization. However, applying a balanced, slow-release fertilizer in early spring can promote healthy growth. The fertilizer should be applied according to the package instructions.
Pruning
To encourage bushy growth, pinch back the tips of the plant when it is young. Prune dead or yellow leaves as necessary, being mindful to avoid damaging the healthy parts of the plant.
Propagation of Oxalis interior (Small) Fedde
Oxalis interior or Small Wood Sorrel is a plant that can be propagated through various methods. Propagation is a process of multiplying and increasing the number of plants, which can be grown from seed or vegetative parts of the plant. The reproduction of Oxalis interior can be done through two primary methods which include:
Seed Propagation
Seed propagation is the simplest method of growing Oxalis interior. Collect the seeds from the fruit capsules that appear after the flowers have bloomed. Sow the seeds in a well-draining potting mix and place them in bright, indirect light. Keep the soil moist by misting it with water. The seeds will germinate within 3-4 weeks. Once the seedlings have grown to a considerable size, they can be transplanted to individual containers.
Vegetative Propagation
Vegetative propagation is another way to grow Oxalis interior and can be done through stem cuttings or division. Follow these steps for both methods:
Propagation through Division
Divide the tubers once the plant is mature and has formed multiple tubers. Carefully uproot the plant and then gently pull the tubers away from the main clump. Replant the tubers in individual pots or in groups if you want to grow more plants at one time. Be sure that each tuber has shoots and roots to ensure success.
Propagation through Stem Cuttings
Take stem cuttings measuring 3-4 inches long from the parent plant. Make sure that the cuttings have at least two leaves and one node. Place the cuttings in a well-draining potting mix, cover the pot with a clear plastic bag to hold the moisture, and place it in indirect light until the cuttings have rooted. Once rooted, remove the plastic bag, and transplant each cutting into its own container.
Oxalis interior is a hardy and resilient plant that can be easily propagated by either seed or vegetative parts. By following the above methods, you can easily grow this beautiful plant in your home garden.
Disease and Pest Management for Oxalis interior (Small) Fedde
Oxalis interior, also known as the Charmed Oxalis, is a low-maintenance houseplant that can be susceptible to a few common diseases and pests. However, with proper plant care and early detection, you can prevent these problems from causing significant damage to your plant.
Common Diseases
One of the most common diseases that can affect Oxalis interior is root rot, which is caused by overwatering or poor drainage. If you notice that your plant's leaves are yellowing or wilting, or the soil smells sour, it may be a sign of root rot. To manage this disease, you should repot your plant into fresh, well-draining soil and reduce watering frequency.
Bacterial blight and leaf spot are two other diseases that can affect Oxalis interior. These diseases are characterized by black lesions on the leaves. To avoid these diseases, you should water your plants at the base and not spray leaves, remove affected leaves, and avoid overcrowding plants to ensure better air circulation.
Common Pests
Oxalis interior can also be affected by some common pests, including spider mites, aphids, and mealybugs. Spider mites are tiny white or red bugs that can cause yellowing and stippling of the leaves. Aphids and mealybugs are small, soft-bodied insects that can suck the plant's juices, leading to stunted growth and leaf drop.
To manage pests on your plants, you should regularly check the plant's leaves for any signs of infestation. You can wash off small populations using a hose, or for badly infested plants, use insecticidal soap. Make sure to move your plant away from other plants to avoid pest transfer.
In conclusion, proper care and attention to your Oxalis interior can help prevent diseases and pests from affecting the plant's health. If necessary, early detection and prompt interventions and treatments can save your plants from afflictions.
