Introduction
Oxalis, also commonly referred to as the “lucky clover” or “false shamrock,” is a popular ornamental plant known for its vibrant, clover-like leaves and delicate blooms. It’s perfect for both garden beds and containers, making it a versatile choice for gardeners of all skill levels. Planting oxalis bulbs (technically corms) is not only an easy process but also rewarding as these low-maintenance plants can provide beautiful pops of color in your home or garden. In this article, we will guide you through a step-by-step process to plant oxalis bulbs successfully, ensuring your garden gets a burst of lush greenery and striking flowers year after year.
What Are Oxalis Bulbs (Corms)?
Before diving into the planting steps, it’s important to understand the nature of oxalis corms. Oxalis, like many other plants in the bulb family, stores its nutrients in underground structures called corms. Corms function similarly to bulbs by storing energy that fuels plant growth. This makes oxalis relatively drought-tolerant and able to thrive with minimal attention, particularly in favorable conditions.
These small corms come in various species and varieties, offering a wide range of leaf shapes and flower colors, from pink and yellow to white and purple. Oxalis is loved not only for its ease of care but also for its potential to be grown indoors as a houseplant or outdoors in gardens, balconies, or even window boxes.
Step-by-Step Guide to Planting Oxalis Bulbs
Here’s how you can plant oxalis bulbs (corms) and watch them bloom into beautiful plants:
1. Choose the Right Variety of Oxalis
There are numerous oxalis varieties, each with different flower colors and leaf shapes. Some popular varieties include:
- Oxalis triangularis: Also known as the purple shamrock, this variety features striking purple leaves and white or pink flowers.
- Oxalis deppei: Also called the “Iron Cross,” this oxalis is famous for its four-leafed green foliage and burgundy center.
Choose the variety that best suits your gardening needs and aesthetic preferences.
2. Select the Perfect Planting Location
Oxalis thrives in well-draining soil and does best when placed in partial shade to full sun, depending on the variety. For indoor planting, choose a spot near a window where the plant will get bright, indirect sunlight. Outdoors, oxalis plants can be placed in flower beds, containers, or even as ground cover.
Indoor planting: If you’re growing oxalis indoors, make sure the area gets ample natural light. Oxalis does well in bright indirect light but can also tolerate lower light conditions.
Outdoor planting: For garden beds, choose an area with some shade, especially in hotter climates, to prevent the plant from scorching. In cooler regions, more direct sunlight is acceptable.
3. Prepare the Soil
Whether planting oxalis indoors or outdoors, the key to success is well-draining soil. Oxalis corms do not tolerate soggy soil, as it can lead to rot. You can improve soil drainage by adding sand or organic compost.
- If planting in containers, use a mix of potting soil and sand or perlite to ensure water can move through the soil easily.
- In garden beds, loosen the soil and mix in organic matter, such as compost or well-rotted manure, to enhance soil structure.
4. Plant the Corms
Once the location is ready and the soil is well-prepared, it’s time to plant the oxalis corms. Follow these simple steps:
- Dig a hole about 1-2 inches deep. For smaller varieties, go closer to 1 inch, while for larger varieties like oxalis triangularis, 2 inches is ideal.
- Place the corms with the pointed side up. If you can’t identify the top, don’t worry too much—oxalis will often right itself as it grows.
- Space the corms about 3 inches apart to give them enough room to spread as they grow.
5. Water the Corms Lightly
After planting, water the area lightly to settle the soil around the corms. Avoid overwatering, as oxalis does not like to sit in soggy soil. Keep the soil slightly moist but not saturated, especially during the first few weeks of planting. Once established, oxalis plants are relatively drought-tolerant.
6. Provide Proper Care and Maintenance
After planting, your oxalis corms will begin to sprout in a few weeks. Here’s how to care for them as they grow:
- Watering: Water regularly, but allow the soil to dry out slightly between waterings. Oxalis can withstand brief periods of drought but thrives with consistent moisture in well-draining soil.
- Fertilization: Fertilize once a month with a balanced liquid fertilizer during the growing season (spring and summer). Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of blooms.
- Mulching: Apply a thin layer of organic mulch around the plants to retain soil moisture and reduce weeds, particularly for outdoor plants.
7. Deadhead Faded Flowers
Regular deadheading (removing spent blooms) will encourage more flowers to grow. Simply pinch or cut off faded flowers near the base to keep your oxalis plant looking tidy and to extend its blooming period.
8. Watch for Dormancy
One unique feature of oxalis is that it tends to go dormant during the summer or in extreme heat. If your plant’s leaves begin to yellow and die back, don’t panic! This is a natural part of the plant’s lifecycle. Simply reduce watering and allow the plant to rest. You can resume regular care once new growth starts to appear in a few weeks.
9. Pest and Disease Management
Oxalis is generally resistant to most pests, but it may occasionally attract aphids, spider mites, or whiteflies. If pests appear, use a gentle insecticidal soap or neem oil spray to treat the affected areas. Keep an eye on the soil for signs of rot, which can occur if the soil remains too wet.
10. Propagate Oxalis by Dividing Corms
Once your oxalis has grown for a season, you can propagate it by dividing the corms. This process is simple:
- Gently dig up the plant during its dormant phase or after the growing season.
- Separate the new corms from the parent plant, ensuring each has a healthy growth node.
- Replant the divided corms following the same steps outlined earlier.
11. Prepare Oxalis for Winter
In colder regions, oxalis is not frost-tolerant and should be brought indoors before the first frost. If planted outdoors in the garden, dig up the corms and store them in a cool, dry place over winter. Alternatively, you can grow oxalis as a houseplant year-round.
12. Enjoy the Benefits of Oxalis Year-Round
Oxalis plants offer more than just beauty—they also have various uses. Some species, like Oxalis deppei, are edible and add a lemony flavor to salads. Others are simply appreciated for their aesthetic value, making them a great gift or a cheerful addition to your home decor.
Conclusion
Planting oxalis bulbs (corms) is a straightforward process that rewards you with stunning foliage and charming flowers, whether indoors or outdoors. With the right location, proper care, and a little patience, you can enjoy this versatile plant for years to come. By following the steps outlined in this guide, you’ll be well on your way to cultivating vibrant oxalis plants that will bring life and color to your space.
