How to Plant Freesia Corms

Depth, spacing & care (Autumn)

Freesias are prized for their beautiful, trumpet‑shaped flowers and intoxicating fragrance. Each stem typically carries multiple blossoms that open sequentially, offering weeks of floral delight. Native to South Africa, freesias thrive in mild climates and are often treated as tender perennials or annuals in cooler zones. Their slender stems and vivid colors make them favorites in cutting gardens, containers, and mixed borders. Over time, they multiply by offsets, filling in patches with graceful, scented floral sprays.

How to plant

When to Plant

In regions without severe frost (hardiness zones 9–10), plant freesia corms in autumn so they can establish before flowering in spring. In colder climates, wait until after the last frost in spring to plant, and treat them as annuals or dig them up before winter.

Where to Plant

Select a site that receives full sun or part shade — freesias need bright light but benefit from some relief in intense heat. The soil should be well-draining, fertile, and rich in organic matter. Avoid locations where water collects or remains soggy.

Preparing the Soil

Loosen the soil to a depth of around 20 cm, removing stones, weeds, and compacted bits. To improve drainage, blend in compost or coarse sand if the soil is heavy. A loose, friable planting bed gives corms room to root and helps prevent rot.

Planting the Corms

Place each corm with the pointed end facing upward. Plant them about 3–5 cm deep and space them around 5–10 cm apart. For the most dramatic effect, plant in groups of 6–8 or more, rather than single lines. In pots, you can position corms more closely to create a fuller cluster.

After Planting

Water gently to settle the soil around the corms, but avoid saturating it. Keep soil moist—but never waterlogged—especially during sprouting and early growth. As foliage emerges, maintain consistent moisture without letting the soil dry out completely.

Spring Growth and Blooming

Shoots will appear within a few weeks. As plants grow, stems may need support if heavy with blooms. Fertilize lightly once buds start forming to encourage flowering. In many cases, freesias bloom about 10–12 weeks after planting.

After Blooming

Remove spent flower stems to redirect energy into the corms. Let the foliage yellow and die back naturally — this is essential for building reserves for next season. In regions where freesia corms won’t survive winter, lift them after foliage has died back, dry them, and store them in a cool, frost-free place until next planting season.

Extra Growing Tips

Freesias are excellent for containers, borders, and cutting gardens. Because their stems can be delicate, provide support or plant among low-growing companions that offer mild structure. Avoid overwatering — rot is a common issue. In frost-prone areas, dig and store corms over winter. Their fragrance, elegance, and ability to naturalize make them a rewarding choice for many gardeners.
