It can tolerate temperatures as low as 50 degrees Fahrenheit, but anything colder can damage the plant. On the other end of the spectrum, temperatures above 80 degrees Fahrenheit can cause the leaves to dry out and the plant to wilt.
Soil Requirements:
Oxalis gracilis Jacq. var. purpurea T.M.Salter prefers well-draining, slightly acidic soil with a pH between 5.5 and 6.5. A mix of peat moss, perlite, and sand provides good drainage and keeps the soil from becoming too compacted. The plant also benefits from occasional fertilization with a balanced fertilizer that is high in phosphorus.
Cultivation
Oxalis gracilis Jacq. var. purpurea T.M.Salter is a beautiful perennial plant that requires well-draining soil and a good amount of sunlight to thrive. It is best grown in USDA hardiness zones 8 to 11. You can grow the plant from seeds or division of rhizomes in spring when the soil has warmed up.
Ensure that you plant the rhizomes at the same depth as they were growing previously. The plant requires regular watering to establish, so water it frequently for the first few weeks after planting.
Watering Needs
Oxalis gracilis Jacq. var. purpurea T.M.Salter requires regular watering to thrive, and it is essential to maintain moist soil around the roots. Avoid over-watering or allowing the soil to remain saturated for extended periods, as this can lead to root rot and fungal infections.
It is best to water the plant early in the day to allow for any excess moisture to evaporate before nightfall. During hot and dry periods, consider watering the plant twice a day to ensure it stays hydrated.
Fertilization
During the growing season, it is essential to fertilize Oxalis gracilis Jacq. var. purpurea T.M.Salter regularly to promote healthy growth and blooming. Use a well-balanced fertilizer with an N-P-K ratio of 10-10-10 or 5-10-5.
You can apply the fertilizer every three to four weeks to ensure the plant has the necessary nutrients to thrive. Avoid over-fertilization, and always follow the manufacturer's instructions carefully.
Pruning
Oxalis gracilis Jacq. var. purpurea T.M.Salter does not require frequent pruning, but you can remove any dead or damaged foliage to maintain the plant's overall health and appearance.
Trim the plant back to ground level after it finishes blooming to encourage new growth and blooming the following season. Avoid pruning the plant late in the growing season, as this may hinder the plant's ability to survive winter.
Always use sharp, sterile pruning tools to prevent the spread of plant diseases.
Propagation of Oxalis gracilis Jacq. var. purpurea T.M.Salter
Oxalis gracilis Jacq. var. purpurea T.M.Salter, commonly known as Purple oxalis or Windowbox wood sorrel, is a popular ornamental plant due to its attractive dark purple leaves and dainty pink or white flowers. The plant is native to South Africa and is propagated through several methods including:
Seeds
Oxalis gracilis Jacq. var. purpurea T.M.Salter can be propagated from seeds, which are formed after the plant flowers in summer. The seeds are small and should be sown in a well-draining potting mix. Place the seeds on top of the soil and lightly cover them with more soil. Keep the soil moist and place it in a warm, bright location until the seeds germinate, which can take several weeks. Once the seedlings have grown, they can be transplanted into individual containers or planted outside.
Division
The plant can also be propagated through division. Carefully dig up the plant and separate its root ball into several sections. Each section should have a good amount of leaves and roots. Replant the sections into individual containers or directly into the ground.
Cuttings
Oxalis gracilis Jacq. var. purpurea T.M.Salter can be propagated through stem cuttings. Take a cutting of about 3-4 inches long from the stem, making sure it has a few leaves and at least one node. Dip the cut end in hormone rooting powder and place the cutting in a well-draining potting mix. Keep the soil moist and place it in a bright, warm location. Once the cutting develops roots, it can be transplanted into its permanent location.
Regardless of the propagation method used, it is important to keep the newly propagated plants moist and in a warm, bright location until they have developed a good root system.
Disease and Pest Management for Oxalis gracilis Jacq. var. purpurea T.M.Salter
Oxalis gracilis Jacq. var. purpurea T.M.Salter, commonly known as the violet woodsorrel, is a plant that can be affected by several diseases and pests. Here are some of the most common ones and ways to manage them:
Diseases:
Anthracnose: This fungal disease appears as brown or black spots on the leaves and stems of the plant, and can cause defoliation. To manage this disease, remove and dispose of infected plant parts, and apply a fungicide as directed.
Downy Mildew: This disease can cause yellowing of the leaves and a white or gray fuzzy growth on the underside of the leaves. To manage this disease, improve air circulation around the plant, reduce humidity, and apply a fungicide.
Rust: This disease appears as brownish-red or yellowish-brown spots on the leaves, often with a rust-colored powdery growth on the undersides of the leaves. To manage this disease, remove and dispose of infected plant parts, and apply a fungicide.
Pests:
Spider Mites: These tiny pests can be difficult to see, but their presence can be detected by the fine webbing they produce and/or yellowing and stippling of the leaves. To manage spider mites, spray the plant with a strong stream of water, apply insecticidal soap or neem oil, and improve humidity levels around the plant.
Aphids: These pests are small and often green or black in color, and can cause distorted growth and yellowing of the leaves. To manage aphids, spray the plant with a strong stream of water, apply insecticidal soap or neem oil, and encourage natural predators like ladybugs.
Caterpillars: These pests can cause visible damage to the leaves and stems, often by chewing through them. To manage caterpillars, remove them by hand when possible, and apply a Bacillus thuringiensis (BT) insecticide as directed.
Overall, proper plant care can help prevent diseases and pests from affecting Oxalis gracilis Jacq. var. purpurea T.M.Salter. This includes regular watering, fertilizing, and pruning to promote healthy growth and strong defenses against pests and diseases.
