Light Requirements
Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth prefers partial shade to full shade. Direct sunlight can quickly dry out the soil and damage the leaves, so it is best to place the plant in a location that receives indirect sunlight for a few hours each day.
Temperature Requirements
Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth is a cold-hardy plant that can tolerate temperatures as low as -25°C. However, the ideal temperature range for this plant is between 10-20°C. Extreme heat should be avoided, as it can cause the plant to wilt and dry out.
Soil Requirements
The soil for Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth should be well-draining, nutrient-rich, and slightly acidic with a pH between 5.5-6.5. It prefers moist soil that is not waterlogged, so the soil should be allowed to partially dry out between waterings. Adding organic matter such as compost can help improve the soil quality and aid in moisture retention.
Cultivation methods
Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth, commonly known as pink wood sorrel, is a herbaceous plant that belongs to the family Oxalidaceae. Pink wood sorrel is native to Europe and Asia and is typically grown as a ground cover in gardens, lawns, and woodland areas.
To grow pink wood sorrel, you need to have well-draining soil with a pH range of 5.5 to 6.5 and a slightly shaded location. The plant is tolerant of a variety of soils but prefers a moist, well-drained site.
Watering needs
Pink wood sorrel requires consistent moisture to thrive, especially during hot, dry weather conditions. It is essential to water the plant regularly but avoid overwatering since overly saturated soil may lead to root rot.
The leaves of pink wood sorrel will droop when it needs water. Ensure you water the plant adequately to maintain its green foliage and prevent the plant from becoming dormant.
Fertilization
Pink wood sorrel does not require a lot of fertilizer. It only needs a slow-release nitrogen fertilizer applied annually in spring. You can also apply a layer of organic compost to the soil to provide nutrients for the plant.
Avoid applying too much fertilizer since it can lead to leafy growth and may reduce flowering.
Pruning
Pruning is not necessary for pink wood sorrel, but you can pinch back the stems to encourage growth and make the plant bushier.
Deadhead any spent flowers to encourage the production of new blooms.
If the plant becomes overgrown, consider dividing it in spring or fall to encourage new growth and maintain its health.
Propagation of Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth
Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth is propagated through two primary methods: seed propagation and vegetative propagation.
Seed Propagation
Propagation of Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth can be achieved by using seeds. For this method, the seeds should be collected from the plants when the seed pods have matured. The seeds should be sown immediately in a seed tray or pots filled with well-drained soil. The seeds must be planted at a depth of around 1 cm under the soil. Keep the seeds moist and in a warm location. It takes approximately two to three weeks for the seeds to germinate. Once the seeds have germinated, allow them to grow to a sufficient size before transplanting. Transplant them to the outdoors, ensuring the location where they are planted receives partial shade.
Vegetative Propagation
The vegetative propagation method for propagating Oxalis acetosella L. var. rhodantha (Fern.) R. Knuth involves using stem cuttings. Select a healthy stem from the parent plant and cut below a node with a pair of disinfected garden shears. Place the cutting in a small pot filled with well-drained soil and keep it moist. The ideal location for cutting propagation is under partial shade. It takes a few weeks for the cuttings to root. Once the cuttings have root, transplant them to a bigger pot or to the outdoors.
Disease Management
Oxalis acetosella L. var. rhodantha is susceptible to a range of diseases, including fungal, bacterial, and viral infections. Common diseases that affect this plant include:
- Leaf spot: This is a fungal disease that causes circular spots on the leaves. To manage this disease, remove affected leaves and dispose of them.
- Powdery mildew: A fungal disease that appears as a white powdery coating on the leaves. To manage this disease, ensure that the plant has good air circulation, avoid over-watering, and prune affected leaves.
- Root rot: This is a fungal disease that attacks the roots of the plant, causing them to rot. To manage this disease, avoid over-watering and ensure that the plant is growing in well-draining soil.
- Virus: There are several viruses that can infect Oxalis acetosella L. var. rhodantha, causing stunted growth, leaf distortion, and yellowing. Unfortunately, there are no effective ways to manage viral infections in plants, so infected plants should be removed and destroyed to prevent the spread of the virus.
Pest Management
In addition to diseases, Oxalis acetosella L. var. rhodantha is also susceptible to pest infestations, with common pests including:
- Aphids: These tiny insects feed on the sap of the plant, causing stunted growth and distorted leaves. To manage aphids, spray the plant with a strong jet of water to dislodge them, or use insecticidal soap.
- Spider mites: These pests are too small to see with the naked eye, but they leave behind fine webbing on the plant. To manage spider mites, hose the plant down with water or use insecticidal soap.
- Slugs and snails: These pests feed on the leaves of the plant, leaving large holes. To manage them, set up slug traps or use iron phosphate bait.
