When to Plant Freesia in Phoenix, Arizona
Freesias are native to South Africa and do well in USDA hardiness garden zones 9 and 10. In Phoenix plant corms in the fall before the first frost. Fall is the best time of year to grow freesia. The best time to plant in Phoenix is in the months of September and October.
In Phoenix first frost usually happens around the middle of December. Planting before then will give freesia time for their roots to establish.
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.

Freesia are tender perennials and grow best when the temperature is 60-70 degrees fahrenheit. Choose a sunny site, preferably one that receives morning sun. Freesia prefer soil with a pH level between 6-7.
Depending on the variety they can grow up to 12-16 inches tall in height.
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.
