Everything it needs
9 essentials at a glance
Watering
Freesia refracta prefers well-drained soil and should be watered moderately.
Water the plant when the top inch of soil feels dry, typically every 7-10 days during the growing season. In winter, reduce watering to once every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and browning leaf tips.
Light
Freesia refracta thrives in full sun to partial shade, ideally receiving 6-8 hours of direct sunlight daily.
A south or west-facing window is perfect for indoor growth. While it can tolerate some shade, too little light can lead to leggy growth and fewer blooms.
Soil
This plant prefers a sandy, well-draining soil mix with a pH range of 6.0 to 7.0.
A recommended potting mix includes equal parts of potting soil, sand, and perlite to ensure good drainage.
Humidity
Freesia refracta enjoys moderate humidity levels around 40-60%.
To increase humidity, consider misting the leaves or placing a humidifier nearby. Signs of low humidity stress include browning leaf edges and slow growth.
Temperature
The ideal temperature range for Freesia refracta is between 60-75°F (15-24°C).
It is hardy in zones 9-11 and can tolerate brief periods of cooler temperatures, but prolonged exposure to below 50°F (10°C) can damage the plant.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 during the growing season, applying every 4-6 weeks.
In fall and winter, reduce fertilization. Signs of nutrient deficiency include yellowing leaves and poor flowering.
Pruning
Pruning is minimal for Freesia refracta.
Remove spent flowers to encourage more blooms and cut back foliage after it has died back in late summer. Use clean, sharp scissors to avoid damaging the plant.
Repotting
Repot Freesia refracta every 2-3 years or when the corms outgrow their pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter and follow the steps of removing the plant, refreshing the soil, and replanting at the same depth.
Propagation
Freesia refracta can be propagated through corm division or seeds.
For corm division, wait until the foliage has died back, then carefully dig up the corms, separate them, and replant at a depth of 2-3 inches. For seed propagation, sow seeds in a well-draining mix in spring, covering lightly with soil, and keep moist until germination.
When it's unhappy
