One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of figuring out when to plant shallots is to refer to the USDA zone info for Norco.

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 are barely cold tolerant which means that you can plant them slightly earlier than plants that are more sensitive to the cold.

The earliest that you can plant shallots in Norco 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. Starting your shallots indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Norco the average date of last frost happens on February 15. You can expect an average low temperature of 25°F in the coldest months of winter.

Keep in mind that USDA zone info for Norco may not be accurate from year to year and the actual date of last frost changes from year to year. Since half of the time in Norco last frost occurs after February 15 be ready to protect your shallots in the event of a surprise late frost.
