Plant Care & Growing Tips

Proper care is essential for maximizing the beauty and longevity of your Oxalis Obtusa Polish Copper bulbs. These bulbs thrive with a clear understanding of their needs, especially regarding planting time, soil, light, and watering. The best time for planting these bulbs is in the fall, specifically from September to October, when temperatures average around 77°F. This timing allows the bulbs to establish themselves before their blooming period from December to May. When considering growing Oxalis Obtusa, always select plump, healthy bulbs to ensure the best start.

For optimal growth, use a loose, well-draining, and aerated soil mix. A good combination includes leaf mold, peat, and perlite. If planting in pots, choose a 6-inch diameter pot and add gravel at the bottom to further improve drainage, preventing waterlogging which can be detrimental to bulbs. Oxalis Obtusa requires at least 3 hours of sunlight daily. They prefer full sun in spring, fall, and winter, but need some shade during the intense heat of summer. Maintain temperatures between 59°F and 77°F for ideal growth, ensuring winter temperatures remain above 41°F. Reduce watering significantly during hot summer temperatures to allow the plant to enter dormancy. After the blooming period, reduce watering and fertilizing, then store the bulbs for the next season. Regular pruning of dead leaves and flowers will encourage new growth and more abundant blooms, contributing to the overall health and vigor of your ornamental Oxalis bulbs.

Watering should follow the “dry out, then water thoroughly” rule; avoid overwatering. For fertilization, apply a diluted phosphorus and potassium fertilizer every 2-3 weeks during spring and fall. Cease fertilizing when the plant enters dormancy. Good ventilation is crucial to prevent common pests and diseases like powdery mildew and red spider mites. Understanding Oxalis Obtusa care ensures a healthy and flourishing plant.
