How to Grow Freesia
Freesia are grown as corms, similar to bulbs but they have a flattened shape. The corms store the energy and nutrients needed for the plant’s growth. Freesia grow well in well-drained soil with morning sun.
Dig a hole twice as deep as the size of the corm or about 2 inches deep. You can put 6-10 corms in in each hole, but space them at least two inches apart.
Corms should be planted with the pointy side facing up. If you want to extend their bloom time, plant corms in succession.

After planting water freesia water well. Then water about an inch a week. Once they start sprouting water so soil is moist. Bulbs don’t like to be soggy, so make sure you have good drainage.
