Light Requirements
Freesia gentilis requires full sunlight to grow. It is a plant that thrives in bright light and prefers to be planted in an area where it can receive at least six hours of direct sunlight each day. The plant may exhibit slower growth or fail to bloom if it does not receive adequate sunlight.
Temperature Requirements
Freesia gentilis grows best in warm temperatures between 18-24°C (65-75°F). The plant is sensitive to low temperatures and frost. If the temperature falls below 10°C (50°F), the plant may stop growing or even die.
Soil Requirements
Freesia gentilis grows well in well-draining soil that is rich in organic matter. It prefers loamy or sandy soil that is slightly acidic with a pH between 5.5-6.5. The plant also requires soil that is well-aerated to prevent root rot. It is essential to ensure adequate drainage to prevent waterlogging and keep the soil moist, but not wet.
Cultivation
Freesia gentilis N.E.Br. requires warm and sun-drenched conditions to grow, but it can tolerate light shade. Plant the corms in fertile, well-drained soil in early autumn or early spring. The plant thrives in areas with mild winters and warm summers. Freesia gentilis N.E.Br. is a fast-growing plant that can reach a height of up to 18 inches.
Watering
Water your Freesia gentilis N.E.Br. regularly during the growing season. The plant loves moist soil, but it is essential to avoid overwatering, which may lead to root rot. Ideally, the soil should be moist, but not waterlogged. During the dormant periods, reduce watering gradually to prevent the corms from drying out.
Fertilization
Apply a balanced liquid fertilizer every two weeks during the growing season to encourage robust growth and blooming. Stop fertilizing once the flowers start to fade to allow the plant to enter its dormant period.
Pruning
Prune your Freesia gentilis N.E.Br. after it has bloomed, once the petals have fallen off. Cut the flower spikes at the base of the stem, taking care not to damage the plant's foliage. Deadhead regularly throughout the growing season by removing spent blooms promptly to promote more flowers. Once the foliage begins to yellow and die back, gently pull the corms from the soil and store them in a cool, dry place for replanting in the following season.
Propagation of Freesia gentilis N.E.Br.
Freesia gentilis N.E.Br. can be propagated through a variety of methods, including seeds, bulbs, and division of clumps.
Propagation through Seeds
The easiest and most common method of propagating Freesia gentilis N.E.Br. is through seeds. The seeds of this plant can be harvested when the seed pods have turned brown and dry. They should be sown immediately after harvesting, as they do not have a long shelf life. Prior to sowing, the seeds can be soaked in lukewarm water for a few hours to soften the hard seed coat. The seeds should be sown at a depth of about 0.5 cm in a moist, well-draining soil mix. The soil should be kept moist, but not waterlogged, until the seeds have germinated.
Propagation through Bulbs
Freesia gentilis N.E.Br. can also be propagated through bulbs. Bulbs can be separated from the parent plant during the dormant season. These bulbs should be planted in a well-draining soil mix at a depth of about 3-4 cm. The soil should be kept moist, but not waterlogged, until the plant has established itself.
Propagation through Division of Clumps
Another method of propagating Freesia gentilis N.E.Br. is through division of clumps. Clumps of plants can be carefully dug up and separated into individual plants. These plants should be planted in a well-draining soil mix at a depth of about 3-4 cm. The soil should be kept moist, but not waterlogged, until the plant has established itself.
