But did you know that the secret to cultivating these enchanting plants lies in understanding how to plant their corms?

Whether you’re a seasoned gardener or a curious beginner, this step-by-step approach will equip you with the knowledge and confidence to successfully cultivate your very own oxalis haven.

Getting Started: Selecting the Perfect Corms

The journey begins with selecting the right oxalis corms. These tiny, bulb-like structures are the key to bringing your oxalis plants to life. Here’s what to look for when choosing corms:

• Firmness: Look for corms that are firm to the touch, indicating they are healthy and viable. Avoid any that are soft or mushy, as these are likely to be damaged or diseased.
• Color: Healthy corms typically have a vibrant brown or reddish-brown color. Avoid any that are discolored or have signs of mold or rot.
• Size: While size doesn’t always guarantee success, larger corms tend to produce larger and more vigorous plants.

The Right Time to Plant Oxalis Corms

The best time to plant oxalis corms depends on your climate and the specific oxalis variety you’ve chosen. Generally, planting in spring or early summer is ideal for most varieties, as it allows them to establish themselves before colder weather sets in. However, some varieties, like the hardy oxalis, can be planted in fall for a stunning display of blooms the following spring.

Preparing the Planting Area

Creating the perfect environment for your oxalis corms is crucial for their growth and development. Here’s how to prepare the planting area:

• Choose the Right Location: Oxalis thrives in partial shade to full shade, especially during the hottest months. Find a spot that receives dappled sunlight or afternoon shade.
• Soil Preparation: Oxalis prefers well-drained soil that is rich in organic matter. Amend your soil with compost or aged manure to improve its drainage and fertility.
• Container Selection: If you’re planting oxalis in containers, choose pots with drainage holes to prevent waterlogging. Use a potting mix that is well-draining and contains organic matter.

Planting Your Oxalis Corms: A Step-by-Step Guide

Now comes the exciting part – planting your oxalis corms! Follow these steps for successful planting:

1. Dig a Hole: Dig a hole that is about twice the diameter of the corm and as deep as the corm itself.
2. Place the Corm: Gently place the corm in the hole with the pointed end facing upwards.
3. Cover with Soil: Backfill the hole with soil, ensuring the corm is fully covered.
4. Water Gently: Water the planting area thoroughly, but avoid overwatering, as this can lead to root rot.
5. Spacing: Space corms about 4-6 inches apart, depending on the variety.

Nurturing Your Oxalis Plants

Once your oxalis corms are planted, it’s time to provide them with the care they need to thrive. Here are some essential tips:

• Watering: Water your oxalis plants regularly, keeping the soil consistently moist but not soggy. Allow the top inch of soil to dry out between waterings.
• Fertilizing: Feed your oxalis plants with a balanced liquid fertilizer every few weeks during the growing season.
• Deadheading: Regularly remove spent flowers to encourage further blooming.
• Dormancy: Oxalis plants enter a dormant period in winter, usually when temperatures drop below 50°F. During this time, reduce watering and allow the soil to dry out slightly.

Oxalis Care: Addressing Common Issues

While oxalis plants are relatively easy to care for, they can sometimes experience issues. Here’s how to address some common problems:

• Yellowing Leaves: This can be a sign of overwatering, underwatering, or nutrient deficiency. Adjust your watering schedule and consider adding a balanced fertilizer.
• Leaf Drop: This can occur during dormancy or if the plant is stressed due to extreme temperatures, lack of light, or pests.
• Pests: Oxalis plants are susceptible to aphids and spider mites. Check your plants regularly for signs of infestation and treat with an appropriate insecticide if necessary.

The Grand Finale: Enjoying Your Oxalis Blooms

With proper care, your oxalis corms will soon sprout into vibrant plants, rewarding you with their captivating blooms. Oxalis flowers come in a range of colors, including pink, purple, yellow, and white. They add a touch of whimsy and charm to any garden, porch, or windowsill.
