Grow fragrant freesia sprays for the garden, patio or vase by matching these South African corms to a cool, bright season. Often called bulbs, freesias grow from corms. Good drainage, careful watering and a dry rest after the leaves finish matter more than a fixed national planting date.
Position
Choose sun, shelter and free-draining soil. Freesias dislike deep shade and soggy compost.
Plant
Set firm corms point-up, 5 cm deep and 5–8 cm apart. Add twiggy support at planting time.
Season
They grow best in cool, bright conditions. Heat above about 15°C can make growth thin and flowers fade quickly.
Plant corms for a cool-season display
Plant in a sunny, sheltered position once local conditions are becoming cool rather than hot. In a garden bed, loosen soil, add mature organic matter only if it will not make the site water-retentive, and make sure water drains away after rain. Place each corm with its pointed end up, 5 cm deep and 5–8 cm apart. This close spacing gives a good display while leaving room for air around the leaves. Water gently after planting; keep soil barely to evenly moist while new roots establish, never wet for long periods.
Push in short twiggy sticks or a light ring before shoots lengthen, especially in a windy site. Do not expect one fixed flowering week: corm condition, planting date and local temperature all change the schedule.
Containers: the easiest way to control drainage
Use a pot with several open drainage holes and a deep root run. Fill it with light potting mix amended with grit, space corms 5–8 cm apart, and keep their tips just above the compost. Give bright airflow and protect from hard frost; a cool sheltered patio is usually better than a warm room.
Keep the mix moist while growing. From the first buds, feed every two weeks with a potassium-rich liquid fertiliser according to its label.
Care in four South African regions
Winter-rainfall Western Cape
Autumn planting suits cool growth, but excellent drainage is vital. Shelter pots if persistent rain saturates the mix.
Frost-prone interior
Use a protected bright container or sheltered microclimate. Cover or move green growth for a damaging frost.
Humid coast and KZN Midlands
Give sun, spacing and airflow. Avoid crowded, wet foliage and continuously wet soil.
Hot, dry and subtropical interior
Grow in the coolest suitable season and use a container to manage temperature and moisture. Do not force growth through sustained heat.
Flowers, cutting and dormancy
Pick vase stems in the cool of morning, leaving foliage behind to feed the corm. Remove spent stems, then continue water and light feeding until leaves yellow naturally. When foliage has died down, stop regular watering. Corms can rest undisturbed only where the soil stays dry during dormancy. Where summer rain or irrigation keeps beds wet, lift them after foliage dies back, dry them gently and store in a warm, dry, airy place until the next suitable planting season.
Troubleshooting
No shoots or soft corms
Discard soft corms. Check point-up planting and correct poor drainage before replanting sound stock.
Long, weak leaves and short-lived flowers
Move to brighter, cooler conditions; warmth and low light make growth spindly. Add support early.
Few flowers next season
Leaves may have been removed too soon or a pot dried hard while green. Let foliage finish naturally.
Safety note
Freesia is grown as an ornamental flower. Keep corms and plant material away from children and pets, and do not treat ornamental planting stock as food.
