Freesia plants grow from corms, which are similar to bulbs and are typically planted in the fall when temperatures dip into the mid-50s. In most areas, freesia is best grown in pots rather than in the ground. Pots can be placed anywhere in the garden but should be kept out of extreme sun and high winds. Freesia corms will eventually multiply, creating offsets that can then be planted to grow more freesia for your garden or to give as a gift.
Plan to plant your freesia in August or September.
Arrange freesia corms in a planting pot that is nearly full of a mixture of potting soil and peat moss. Cover them with a thin layer of soil.
Water sparingly, waiting for the soil to become nearly dry between waterings.
Fertilize the freesia once when they begin to grow and again when the first flower shoots appear.
Dig up the corms when the freesia has finished flowering and the leaves and stems begin to yellow.
Remove all growth from the corms.
Bury the corms at least one inch deep in soil until the next August or September, when you can repeat the process.
