The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. 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 estimating when to plant leeks is to look at the USDA zone info for Ventura.

Planting Calendar for Leeks

Frost tolerance for leeks:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since leeks are very cold tolerant you can plant them a lot earlier in the year than more sensitive plants.

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

The last month that you can plant leeks and expect a good harvest is probably October. You probably don't want to wait any later than that or else your leeks may not have a chance to really do well. You can get started a few weeks earlier by starting your leeks indoors.

Last Frost Date

In Ventura the average date of last frost happens on January 31. In the coldest months of winter you should expect an average low temperature of 30°F.

Remember that the actual date of last frost is just an average because it is based on the USDA zone info for Ventura and it will vary from year to year. Half of the time in Ventura it frosts late in the year after January 31 so make sure that you are ready to cover your leeks if you have one of those late frosts.
