When Is The Average First Frost Date In Utah?
The average first frost (or freeze) date for the Wasatch Front in Utah is around the middle of October. This means that around this time a hard freeze will cause your garden plants to die if they are annuals or they are not cold-hardy. You can pull them out before this happens or you can wait until after it happens. If you wait until after the first frost of fall to pull out your plants, you can enjoy them right up until the last day before it freezes - fall flowers and fall vegetables. Perennials (plants that grow back every year) can be cut back in the fall, but I think it's better to wait until spring; let them die back naturally over the winter.
