What is Oxalis?
Oxalis, often called wood sorrel or shamrock plant, belongs to the Oxalidaceae family.

Most Oxalis species are perennial, meaning they can live for several years with proper care. They range in size from small, ground-hugging varieties to more upright, bushy types. The flowers are usually small and delicate, adding an extra touch of charm. They come in colors like white, pink, yellow, and purple, depending on the specific variety.

Caring for Your Oxalis
Alright, you're hooked and ready to bring an Oxalis home. Here’s how to keep it happy and thriving:
Light
Oxalis plants love bright, indirect light. Too much direct sunlight can scorch their delicate leaves, while too little light can cause them to become leggy and lose their vibrant color. A spot near an east- or west-facing window is usually ideal. If you're growing your Oxalis outdoors, choose a spot that gets morning sun and afternoon shade. This will protect the plant from the harsh midday sun while still providing it with the light it needs to thrive.
During the winter months, when light levels are lower, you may need to supplement with artificial light. A simple fluorescent grow light can make a big difference in keeping your Oxalis happy and healthy. Position the light a few inches above the plant and keep it on for several hours each day. This will help prevent the plant from becoming weak and spindly.
Watering
Water your Oxalis when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. Oxalis plants prefer slightly moist soil, but they don't like to sit in soggy conditions. When you water, make sure to thoroughly saturate the soil until water drains out of the bottom of the pot. This will ensure that the roots are getting the moisture they need.
During the dormant period, which usually occurs in the winter, you can reduce watering frequency. The plant may lose some of its leaves during this time, but don't worry – it's just resting. Water sparingly, only enough to keep the soil from completely drying out. Once new growth appears in the spring, you can resume your regular watering schedule.
Soil
Oxalis plants prefer well-draining soil. A mix of potting soil, perlite, and peat moss is a good option. This combination provides the right balance of moisture retention and drainage. You can also add a small amount of compost to the soil mix to provide extra nutrients. Avoid using heavy, clay-based soils, as these can retain too much water and lead to root rot.
When repotting your Oxalis, choose a pot that is only slightly larger than the previous one. Oxalis plants don't mind being slightly root-bound, and a pot that is too large can hold too much water. Make sure the pot has drainage holes to allow excess water to escape.
Temperature and Humidity
Oxalis plants prefer moderate temperatures between 60°F and 75°F (15°C and 24°C). Avoid placing them near drafts or sources of extreme heat or cold. While Oxalis plants can tolerate a range of humidity levels, they prefer slightly higher humidity. If your home is particularly dry, you can increase humidity by placing the plant on a pebble tray filled with water or using a humidifier.
Fertilizing
Feed your Oxalis every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Avoid fertilizing during the dormant period (fall and winter). Over-fertilizing can lead to leggy growth and weak stems. Choose a fertilizer that is specifically formulated for houseplants and follow the instructions on the label carefully.
Pruning
Prune your Oxalis to remove any dead or yellowing leaves. This will help keep the plant looking its best and prevent the spread of disease. You can also prune the plant to control its size and shape. Use clean, sharp scissors or pruning shears to make the cuts. Avoid tearing or crushing the stems, as this can damage the plant.
Common Problems and Solutions
Even with the best care, Oxalis plants can sometimes encounter problems. Here are some common issues and how to address them:
- Leggy growth: This is usually caused by insufficient light. Move your Oxalis to a brighter location or supplement with artificial light.
 - Yellowing leaves: This can be caused by overwatering, underwatering, or nutrient deficiencies. Check the soil moisture and adjust your watering schedule accordingly. Fertilize the plant if necessary.
 - Pests: Oxalis plants can be susceptible to pests like spider mites and aphids. Treat infestations with insecticidal soap or neem oil.
 - Dormancy: As mentioned earlier, Oxalis plants can go dormant in the fall and winter. During this time, they may lose some or all of their leaves. Reduce watering and stop fertilizing until new growth appears in the spring.
 
Propagating Oxalis
Want more Oxalis? You can easily propagate them by dividing the bulbs or tubers. Here's how:
- Carefully remove the Oxalis from its pot.
 - Gently separate the bulbs or tubers.
 - Plant each bulb or tuber in its own pot filled with well-draining soil.
 - Water thoroughly and place in a bright location.
 
With a little patience, you'll have a whole new collection of Oxalis plants to enjoy!
