How Much Space to Leave Between Each Oxalis Plant

Oxalis, commonly known as wood sorrel or shamrock, is a beautiful perennial plant that adds a touch of charm to any garden or landscape. With its delicate flowers and attractive foliage, it is no wonder that many gardeners are eager to include this plant in their gardens.

When it comes to planting oxalis, one crucial factor to consider is the spacing between each plant. Giving adequate space between plants ensures proper air circulation, reduces the risk of disease, and allows each plant to grow and thrive to its full potential. In this article, we will discuss how much space you should leave between each oxalis plant.

Understanding the Growth Habit of Oxalis

Before we delve into the spacing requirements for oxalis plants, it is essential to understand their growth habit. Oxalis plants can spread through rhizomes or bulbs, depending on the variety. Some oxalis species, such as Oxalis triangularis (commonly known as purple shamrock), have rhizomes that can spread rapidly underground. Other species, such as Oxalis deppei (commonly known as iron cross), produce bulbs that multiply over time.

Considering the growth habit of oxalis is important because it affects how much space each plant needs. Rhizomatous varieties require more space between each plant compared to bulbous types.

Spacing for Rhizomatous Oxalis Varieties

Rhizomatous oxalis varieties, with their underground rhizomes, tend to spread out and form dense clumps over time. To prevent overcrowding and promote healthy growth, these varieties require ample space between each plant.

For rhizomatous oxalis varieties, it is recommended to leave at least 12-18 inches (30-45 cm) of space between each plant. This spacing ensures that the plants have enough room for their rhizomes to expand without competing for resources. It also allows for proper air circulation, reducing the risk of fungal diseases.

Spacing for Bulbous Oxalis Varieties

Bulbous oxalis varieties, on the other hand, tend to multiply through bulbs that divide and form new plants. While they may not spread as rapidly as rhizomatous varieties, they still require sufficient space to grow and thrive.

For bulbous oxalis varieties, a spacing of 6-10 inches (15-25 cm) between each plant is generally recommended. This spacing allows the bulbs to develop and multiply without overcrowding. However, if you have larger varieties or want to give your plants more room to spread out, you can increase the spacing to 12 inches (30 cm).

Tips for Planting Oxalis

When planting oxalis, there are a few additional tips to keep in mind to ensure successful growth:

1. Prepare the soil: Before planting oxalis, make sure the soil is well-drained and rich in organic matter. Oxalis prefers slightly acidic soil with a pH range of 5.5-6.5.

2. Planting depth: The general rule of thumb for planting oxalis bulbs or rhizomes is to bury them about 2-3 inches (5-7.5 cm) deep. Make sure to space them according to the recommendations mentioned earlier.

3. Watering: Oxalis plants prefer consistently moist soil but can be susceptible to root rot if overwatered. Water them deeply when the top inch of soil feels dry, and avoid standing water.

4. Sunlight requirements: Most oxalis varieties thrive in partial shade or filtered sunlight. However, some species can tolerate full sun or full shade. Check the specific requirements of your chosen variety before planting.

5. Maintenance: Remove any weeds or competing plants regularly to prevent them from choking out your oxalis. Additionally, deadhead the flowers once they fade to encourage continuous blooming.

By following these tips and providing adequate spacing between each oxalis plant, you can create a beautiful and healthy garden display that will be the envy of your neighbors.

Final Thoughts

Proper spacing is crucial for the healthy growth and development of oxalis plants. Whether you are planting rhizomatous or bulbous varieties, giving them enough room to spread out ensures optimal air circulation, reduces the risk of diseases, and allows each plant to flourish. By following the recommended spacing guidelines mentioned in this article, you can create a stunning oxalis display that will bring joy and beauty to your garden for years to come.
