WHERE TO PLANT

As they're easy growers both in-ground and in containers, feel free to use this plentiful plant for edging, container gardens, or as indoor windowsill accents.

Oxalis love sunlight but appreciate some protection during the hottest part of the day. For example, south-facing windows are perfect for winter but may be too hot during the summer.

In USDA zones 6 through 10, it can grow outdoors in borders or edgings but should be treated as a houseplant in cold winter areas.

HOW TO PLANT

Oxalis go dormant in the summer rather than the winter and prefer being planted in the spring.

• For outdoor landscape planting, dig holes and position them 3–4" apart at a depth of 1–1 ½". After placing the bulbs in the holes, cover with the surrounding soil.
• For container planting, fill about three-quarters full with a well-drained potting mix. Water to settle the soil before placing the bulbs on top several inches apart. Cover the bulbs with 1–2" of additional soil.
• Water lightly, ½ to 1 cup will usually do the trick until top growth emerges.

HOW TO GROW

• Water lightly during active growth about once per week when the top half of the soil feels dry.
• Fertilize your Oxalis lightly with a diluted liquid fertilizer once every month while the plant is actively growing.
• Prune away dead foliage in late summer as the plant begins to die and slip into dormancy.
• Stop watering and fertilizing while your plant rests in its dormancy period.
• Resume watering and fertilizing once your Oxalis begins to regrow in the spring.
