Before planting it is a good idea to find your USDA Zone info to estimate your garden 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 making a decision about when it's the best time to plant zucchini is to consult the USDA zone info for Lake Forest.

Planting Calendar for Zucchini

Frost tolerance for zucchini:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

Since zucchini are not cold tolerant you need to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant zucchini in Lake Forest 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 zucchini and expect a good harvest is probably September. You probably don't want to wait any later than that or else your zucchini may not have a chance to really do well. Starting your zucchini indoors is a great way to get them started a little bit earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on January 31 in Lake Forest. In the coldest months of winter you should expect an average low temperature of 30°F.

Since the USDA zone info for Lake Forest is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Lake Forest there is a last frost after January 31 so always be ready to cover your zucchini in the event of one of those late frosts.
