|Your average last frost date is about May 11 so you'll either want to wait until after that date to plant your gladiolus or plan on providing them with some frost protection if you plant them outdoors now. If you do plant your glads now you simply need to be ready to cover them if frost is predicted. You can use hotcaps, Wall O' Water, or other protective covers. Shallots are a little more cold tolerant and can be planted outdoors now. Typically they can be planted outdoors 6-8 week prior to your average last frost date. Best wishes with your garden!
