Spokane Planting Calendar. Planting vegetable seeds or transplants at the correct time is important for getting the most out of your garden. Corn = begin planting on may 1st at one (1) week increments.

In the spokane area, we plant our gardens in waves starting with the crops that can take cooler temperatures, followed by crops that need warmer weather and ending with the cooler weather crops. Beets = plant the first week of april and throughout the month.
