How to plant Oxalis bulbs

Depth, spacing & care (Spring)

Oxalis brings joyful movement and soft color to spring gardens. With clover-like foliage that often folds and unfolds with the light, and dainty blooms in soft pink, white, yellow, and lavender, it adds a whimsical touch to borders, rockeries, containers, and woodland edges.

Though delicate in appearance, Oxalis is resilient and fast to establish. Its low-growing habit makes it perfect as ground cover beneath taller spring bulbs, and in containers, it spills gracefully over the edge. Some varieties even have burgundy or variegated foliage that provides interest well beyond the flowering season.

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.
