What This Means for Visalia Gardeners
The average last spring frost in Visalia is around February 18, and the average first fall frost arrives around November 20. That gives you approximately 275 frost-free days to work with.

Most frost-sensitive crops can be transplanted by February 18, giving them months to produce before fall. Your winter garden is the real advantage — growing fresh vegetables in December and January while northern gardeners browse seed catalogs.
