The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of determining when to plant shallots is to use the USDA zone info for Gridley.

Planting Calendar for Shallots

Frost tolerance for shallots:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Shallots can survive in very little cold which tells us that you can plant them just a tiny bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant shallots in Gridley is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant shallots and expect a good harvest is probably September. Any later than that and your shallots may not have a chance to grow to maturity. If you are starting your shallots indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on February 15 in Gridley. You can expect an average low temperature of 25°F in the coldest months of winter.

Since the USDA zone info for Gridley is not always accurate the actual date of last frost changes from year to year. Half of the time in Gridley last frost occurs after February 15 so make sure that you are ready to protect your shallots in the event of a surprise late frost.
