How to plant
When to plant
Plant Oxalis bulbs in early to mid-spring after the risk of frost has passed. In warmer climates, planting can begin earlier, while cooler areas may wait until soil temperatures rise.
Where to plant
Choose a location with full sun to partial shade. Oxalis loves bright light but benefits from afternoon shade in hot regions. Ensure the planting area drains well — these bulbs dislike standing water.
Preparing the soil
Loosen the soil to about 15 cm deep and remove stones or compacted patches. Enrich with compost to support root development. In heavy soils, add grit or coarse sand to keep drainage optimal.
Planting the bulbs
Set the small bulbs with their pointed side up, about 2.5 to 4 cm deep and 7–10 cm apart. In containers, use a loose, well-draining potting mix and avoid overcrowding for even growth.
After planting
Water once after planting to settle the soil. Then keep lightly moist until shoots appear — avoid overwatering, especially before active growth.
During growth and blooming
Oxalis leaves emerge quickly, followed by charming, pop-up blooms. Feed every few weeks with a balanced fertilizer during flowering. Deadhead spent blooms to tidy the plant and encourage continued blooming.
After blooming
Allow foliage to yellow and die back completely — this process stores energy in the bulbs. In frost-prone areas, lift and store bulbs in a cool, dry place. In mild zones, bulbs can remain in place and multiply naturally.
Extra tips
Oxalis does well in rock gardens, containers, and between paving stones. Use in drifts for a soft carpet effect, or in pots where its leaf movement can be admired up close. Most types are deer- and pest-resistant and require little care once established.
