Everything it needs
9 essentials at a glance
Watering
Golden Oxalis prefers to be kept moderately moist but not soggy.
Water when the top inch of soil feels dry, typically every 1-2 weeks. In the growing season (spring and summer), increase frequency, while in fall and winter, reduce to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
Golden Oxalis thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, it should receive 4-6 hours of light daily. Too much direct sun can scorch the leaves, while too little light can lead to leggy growth.
Soil
A well-draining potting mix is ideal, with a pH range of 6.0 to 7.0.
A mix of potting soil, perlite, and sand works well to ensure proper drainage and aeration, preventing root rot.
Humidity
This plant prefers moderate to high humidity levels, ideally around 50-70%.
To increase humidity, consider using a pebble tray with water or a humidifier. Signs of low humidity include brown leaf tips and edges.
Temperature
Golden Oxalis thrives in temperatures between 60-75°F (15-24°C).
It is not frost-tolerant and should be kept above 50°F (10°C). It can tolerate higher temperatures but may require more frequent watering.
Fertilizing
Use a balanced, water-soluble fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
Reduce or stop fertilizing in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Golden Oxalis in late winter or early spring before new growth begins.
Remove any dead or yellowing leaves to promote healthy growth. Use clean, sharp scissors for cutting to prevent disease.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Signs include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter. Gently remove the plant, refresh the soil, and place it in the new pot.
Propagation
Propagation can be done through bulb division or offsets.
In spring, carefully remove the bulbs from the soil, separate them, and replant them in fresh soil. Ensure each bulb has roots attached. Water lightly until established.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Check soil moisture and reduce watering frequency. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Wilting leaves
Why it happens
Under-watering or low humidity.
How to fix it
Increase watering frequency and consider increasing humidity levels around the plant.
Brown leaf tips
Why it happens
Low humidity or over-fertilization.
How to fix it
Increase humidity through misting or a pebble tray, and reduce fertilizer application.
Leggy growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location to encourage more compact growth.
Root rot
Why it happens
Over-watering and poor drainage.
How to fix it
Ensure the pot has drainage holes, reduce watering, and consider repotting in fresh, well-draining soil.
Care through the year
Spring
In spring, increase watering and begin fertilizing every 4-6 weeks. Prune any dead leaves to encourage new growth.
Summer
During summer, maintain consistent moisture and ensure the plant receives adequate light. Monitor for pests, as they may thrive in warmer conditions.
Fall
In fall, gradually reduce watering as the plant enters dormancy. Stop fertilizing and prepare for winter by ensuring it is in a suitable location.
Winter
In winter, water sparingly and keep the plant in a warm area, avoiding drafts. Ensure it receives some light, but avoid direct sunlight.
