Plant Care & Growing Tips

Proper care ensures your Oxalis Obtusa Yellow River bulbs thrive and produce abundant blooms. The ideal planting period is during fall (September to October) when temperatures hover around 77°F, leading to blooming from December to May. When it comes to soil, these bulbs prefer a loose, well-draining, and aerated mix. A good combination might include leaf mold, peat, and perlite to provide the necessary structure and drainage. If planting in pots, a 6-inch diameter pot with gravel at the bottom can significantly improve drainage, preventing waterlogging which can be detrimental to bulbs.

For optimal growth, flowering Oxalis requires at least 3 hours of sunlight daily. They perform best in full sun during spring, fall, and winter, but appreciate some shade during the intense summer heat. The ideal temperature range is between 59°F and 77°F. During winter, ensure temperatures remain above 41°F. It’s crucial to reduce watering during hot summer temperatures as the plant enters dormancy. After the flowering period concludes, gradually reduce watering and fertilizing to allow the bulbs to rest before storing them for the next season. When watering, follow the “dry out, then water thoroughly” rule to avoid overwatering. Fertilize with a diluted phosphorus and potassium fertilizer every 2-3 weeks during spring and fall, discontinuing during dormancy. For planting, select plump, healthy bulbs. Add bottom fertilizer to the planting site, place the bulbs with shoots facing up, cover with 2 cm of soil, and water thoroughly. Regular pruning of dead leaves and flowers will encourage new growth and more blooms. Ensure good ventilation to prevent common issues like powdery mildew and red spider mites.

Size & Details

The Oxalis Obtusa Yellow River bulbs typically produce plants that grow to a compact height of up to 10 cm (approximately 4 inches), making them an excellent choice for front borders, rock gardens, or container plantings. The bulb sizes vary by variety, and these will be shipped as healthy, dormant bulbs ready for fall planting. Each bulb contains the potential for multiple leaves, which are typically hairy or hairless and trifoliate (three-lobed), adding textural interest even before flowering. The solitary flowers, appearing in vibrant yellow, create a striking contrast against the green foliage. These bulbs are designed for easy establishment and rapid growth once planted under suitable conditions. Expect blooms to emerge approximately 2-3 months after planting, providing cheerful color throughout the cooler seasons.

These bulbs are perfect for creating a beautiful, low-growing display. They are shipped in a dormant state to ensure successful transplantation and are ideal for establishing a long-term presence in your garden, naturalizing over time to form larger colonies. The relatively fast growth rate and abundant flowering make them a rewarding addition to any plant collection, especially for those interested in a beautiful flowering Oxalis.
