One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Kaplan you can estimate when it's possible to plant leeks by checking out the USDA zone info.

Leeks do well in a bit of cold which tells us that you can plant them earlier in the year than more sensitive plants.

The earliest that you can plant leeks in Kaplan 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. If you wait any later than that and your leeks may not have a chance to grow to maturity. If you are starting your leeks indoors then you might be able to get away with starting them a little bit earlier.
