Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

It's possible to figure out when it's a good idea to plant shallots by looking at the USDA zone info for Zone 10a.

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 some cold which means that you can plant them a bit earlier in the year than more sensitive plants.

The earliest that you can plant shallots in Zone 10a 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. You probably don't want to wait any later than that or else your shallots may not have a chance to fully mature. Starting your shallots indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is January 31 in Zone 10a. In the coldest months of winter you can expect an average low temperature of 30°F.

Since the USDA zone info for Zone 10a is just an average the actual date of last frost is different every year. Half of the time in Zone 10a it frosts late in the year after January 31 so make sure that you are prepared to cover your shallots if you have one of those late frosts.
