Last Frost Date

Always keep in mind that our actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 7a and it changes from year to year. Half of the time in Zone 7a there is a last frost after April 15 so make sure that you are ready to cover your euphorbia if we have a surprise late frost.
