Freesia is a bulb growing plant that produces fragrant funnel shaped flowers in the spring and winter seasons. The plant is native to South Africa and is similar in appearance to the iris plant. Freesia plants grow up to 15 to 24 inches tall and are commonly planted in containers versus being planted in the ground. Sow freesia seeds in spring from January to April or wait until August after the heat of summer. Seed germination takes approximately 25 to 30 days.
Soak the freesia seeds in warm water for 24 hours prior to placing in soil.
Fill seed starting trays or pots with a sterile seed starting medium that contains equal portions of sandy compost, fibrous loam, leaf mold and sand that has been filtered to pull out large pieces.
Lightly moisten the medium prior to placing in containers. Do not pack the soil. Create furrows or holes in the soil that are ¼ inch deep and ½ inch apart.
Sow the seeds into the soil holes and cover lightly with soil. Water the seeds lightly and continue to water to keep the soil moist.
Place the seed containers in a location that has good ventilation and a temperature of 60 to 70 degrees F during the germination process.
Thin out excess seedlings once they are several inches high if they are growing close together in a pot.
Fertilize the seedlings every two weeks with a liquid house plant fertilizer once the plants reach a height of two inches.
Freesia seedlings will grow outdoors in an open but shaded location. Move the plants indoors when the temperature drops below 60 degrees F.
Transplant the freesia bulbs in groups of five to six bulbs to a larger container when necessary. It is possible to transplant freesia directly into a flower bed that has a nutrient rich and well draining soil. Place each plant 10 feet apart in a sunny location. Water the plants to keep the soil moist until the flowering. The plants require less water after flowering is complete.
