Plant Care & Growing Tips

To ensure your Oxalis Obtusa Sunshine bulbs flourish and produce their spectacular blooms, follow this detailed care guide. The best planting period is in the fall, specifically from September to October, when temperatures average around 77°F. This timing allows the bulbs to establish before their blooming cycle from December to May.

For soil and potting, it’s crucial to use a loose, well-draining, and aerated mix. A blend of leaf mold, peat, and perlite is ideal. When potting, choose a 6-inch diameter pot and add gravel at the bottom to enhance drainage, preventing waterlogging which can harm the bulbs. In terms of light, your Oxalis needs at least 3 hours of sunlight daily. Provide full sun during spring, fall, and winter, but offer some shade during hot summer months to protect the delicate foliage and encourage dormancy. The optimal temperature range for active growth is between 59°F and 77°F, and in winter, ensure temperatures stay above 41°F. Reduce watering during hot summer temperatures to allow the plant to enter its natural dormancy phase. After the vibrant display of colorful Oxalis flowers, gradually reduce watering and cease fertilizing, then store the bulbs for the next season.

Watering should follow the “dry out, then water thoroughly” rule; never let the pot sit in standing water. Fertilize every 2-3 weeks in spring and fall with a diluted phosphorus and potassium fertilizer, stopping completely during dormancy. When planting, select plump, healthy bulbs. Add bottom fertilizer to the pot, place the bulbs with the shoots facing up, cover with 2 cm of soil, and water thoroughly. Daily care includes regularly pruning dead leaves and flowers to encourage continuous new growth and blooming. Ensure good ventilation to prevent common issues like powdery mildew and red spider mites. Following this Oxalis planting guide will help you achieve the best results.
