Gardeners in hardiness zones 9 and warmer can plant freesias in the fall. In other zones, freesias should go into the ground in spring; they’ll need to be dug and stored at the end of the growing season so they don’t perish in the cold. If you don't want to dig them back up, simply start over next year with fresh bulbs (technically, they’re corms). Freesias are usually inexpensive. Plant the corms 2” deep in soil that drains easily, and give them a spot that gets sun to light shade.
