We've seen a lot of beautiful flowers and herbs leaving the greenhouse the past few weeks. Below is a chart showing average LAST FROSTS in Michigan Frost Dates.

Two of the most important dates for any gardener to know (especially vegetable gardeners) are the frost dates for your area. The spring frost date is the estimated day of the last hard frost of winter. The fall frost date is the estimated day of the first hard, killing frost of late autumn.

The spring frost date is largely considered the first day of the outdoor gardening season. After this day it is unlikely that you will get a hard frost that would kill tender plants.

The fall frost date is basically the end of the outdoor gardening season for tender plants including most garden vegetables (unless you use season extenders such as row covers, cold frames, etc.).

The following is a list of the spring and fall frost dates for many Michigan communities. These dates come from data at the National Climatic Data Center web site and should be considered more of a guideline rather that information that is set in stone. Some years will be a little warmer and some a little cooler. In a cool and rainy spring you might want to wait a week or two longer to plant out your tomatoes. If you’re having a particularly warm fall you can probably count on an additional 2 or 3 weeks of harvesting cucumbers and zucchini. Pay attention to your environment (and your local weather reports) and act accordingly.

Be sure to cover or bring in tender plants if there is a chance of frost in your area.

AND...be glad you don't live in Champion! Can you imagine waiting until July 9th? Happy Gardening!!
