Oxalis, commonly known as wood sorrel, is a captivating genus of plants that boasts an array of vibrant hues and delicate foliage. Its charm extends beyond its aesthetic appeal, as it is also known for its medicinal properties. If you’re eager to incorporate these enchanting plants into your garden, this comprehensive guide will provide you with all the essential steps on how to plant oxalis tubers successfully.
Choosing the Right Oxalis Tubers
The first step towards a thriving oxalis garden is selecting healthy tubers. Look for tubers that are firm, plump, and free from any blemishes or signs of decay. Choose varieties that suit your climate and garden conditions, as some species prefer moist, shady environments, while others thrive in drier, sunnier locations.
Preparing the Soil
Oxalis plants prefer well-drained soil that is rich in organic matter. Amend your soil with compost or well-rotted manure to improve its fertility and drainage. The ideal pH range for oxalis is between 6.0 and 7.0, but they can tolerate slightly acidic or alkaline conditions.
Planting Depth and Spacing
Determine the appropriate planting depth based on the size of your oxalis tubers. Plant larger tubers about 2 inches deep, while smaller tubers can be planted at a depth of 1 inch. Space the tubers approximately 6-8 inches apart to allow for adequate growth and spread.
Watering
Water the oxalis tubers deeply after planting, especially if the soil is dry. Allow the soil to dry out slightly between waterings, as overwatering can lead to tuber rot. During the active growing season, water regularly to keep the soil moist but not soggy.
Fertilizing
Oxalis plants are not heavy feeders and typically do not require frequent fertilization. However, if you notice signs of nutrient deficiency, such as yellowing leaves or stunted growth, apply a balanced liquid fertilizer diluted to half strength.
Mulching
Mulching around oxalis plants helps retain moisture, suppress weeds, and regulate soil temperature. Use organic materials such as compost, shredded leaves, or bark chips as mulch. Spread the mulch in a 2-3 inch layer around the plants, taking care not to bury the stems.
Dividing and Replanting
Oxalis plants can become overcrowded over time, especially in ideal growing conditions. To maintain their vigor and prevent overcrowding, divide and replant the tubers every 2-3 years. Dig up the clumps in the fall or spring, gently separate the tubers, and replant them in fresh, amended soil.
Overwintering
In colder climates, oxalis tubers may need to be overwintered indoors to protect them from freezing temperatures. Dig up the tubers in the fall after the foliage has died back. Store them in a cool, dry place with good ventilation. When spring arrives, replant the tubers outdoors after the last frost date.
Troubleshooting Common Problems
Despite proper care, oxalis plants may occasionally encounter problems. Here are a few common issues and their solutions:
- Yellowing leaves: Nitrogen deficiency or overwatering. Fertilize with a balanced liquid fertilizer or adjust watering practices.
- Stunted growth: Nutrient deficiency or poor drainage. Fertilize or improve soil drainage.
- Tuber rot: Overwatering or planting in poorly drained soil. Allow soil to dry out between waterings and ensure adequate drainage.
- Pests: Aphids or spider mites. Use insecticidal soap or neem oil to control pests.
Final Note: Embracing the Beauty of Oxalis
With proper planting and care, oxalis tubers will thrive and reward you with a vibrant display of colorful blooms and attractive foliage. Whether you’re a seasoned gardener or a novice enthusiast, incorporating these charming plants into your garden will add a touch of elegance and natural beauty to your outdoor space.

A: Water oxalis plants regularly, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to tuber rot.
Q: Are oxalis plants toxic to pets?
A: Oxalis plants contain oxalic acid, which can be toxic to pets if ingested in large quantities. Keep oxalis plants out of reach of pets or grow them in a raised bed to prevent access.
Q: Can oxalis plants be grown from seed?
