Freesia refracta, commonly known as freesia, is a tuberous geophyte in the family Iridaceae. Native to South Africa, it is well-known for its fragrant, funnel-shaped flowers that come in a variety of colors. Freesias are popular in gardens and as cut flowers. They thrive in subtropical climates and have a dormancy period during which the corms should be kept dry.
Freesias require bright, indirect light and moderate temperatures. They prefer a humid environment but can tolerate average household humidity levels. Water the plant when the top inch of soil feels dry, and ensure good air circulation to prevent fungal issues.
土壤
Freesias prefer well-draining loam soil. A mix of garden soil, sand, and compost works well. Ensure the soil is kept moderately moist but not waterlogged, as the corms can rot in overly wet conditions.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize every 2-3 weeks during the growing season to promote healthy growth and flowering.
换盆
Repot freesia corms every year after the dormancy period. Remove the old corms and plant new ones in fresh soil. Ensure the new pot has good drainage to prevent waterlogging.
传播
Freesias can be propagated by dividing the corms. After the flowering season, dig up the corms, separate the offsets, and replant them. This is best done during the dormancy period.
修剪
Pruning is not typically required for freesias. However, you can remove spent flowers and yellowing leaves to keep the plant looking tidy and to encourage new growth.
毒性
Freesias are non-toxic to pets and humans, making them a safe choice for households with animals and children.
额外的
Freesias are sensitive to frost, so if you live in a cooler climate, consider growing them in pots that can be moved indoors during cold weather. They also benefit from a period of dormancy, during which watering should be reduced.
