A useful listing of city and state specific Last Freeze and Last Frost dates.

Thanks - Mrs Colonel and I were just discussing this morning whether to take the plants out of the greenhouse. Guess I’ll wait another couple of weeks.

Typically, blogs do not need to be excerpted on Free Republic. :-) ****

The most important factor in determining when to plant a certain type of vegetable in your garden is the “Last Freeze Date” in the spring, and the “First Freeze Date” in the fall for your area. These dates for a given area are based on historical weather data from that area over a 30 year period compiled by the National Climatic Data Center.

The actual dates that the freezing temperatures occurred each year in a given area, during this 30 year period, are averaged together. Probabilities of a freeze occurring are then assigned to these average dates.

Let’s look at an example.

This chart shows the Last Freeze/Frost dates for Abeline, TX.

The first column shows the City and State name.

The second column shows three temperatures. The first temperature, 36°F, is the Frost temperature. Temperature monitoring stations are typically mounted four to six feet above the ground. During clear, calm, and cold nights the temperature at ground level, where your garden is, can become much colder. The second temperature, 32°F, is the Freeze temperature. The third temperature is the Hard Freeze temperature.

The third column titled Spring Date has three sub-columns in it titled Probability Level 90, 50, and 10 with dates listed under them. The lower the probability level number, the less likely it is that a Frost, Freeze, or Hard Freeze will occur on that date.

The Last Freeze Date for this example is April 10. This means that there is only a 10 percent chance that it will freeze on this date. Remember, although statistically accurate, you are really just playing the odds with this date. Before planting you should ALWAYS check your local weather to see if a freeze is in the forecast.

Do not worry about the self appointed anti blog pimp pimps. But I would recommend that you ping JustaDumbBlonde, she maintains the gardening list and can help get the info out.

Well, it looks like it will be safe to put the garden in between May 11 and May 29 and to lay down weed control granules in the flower gardens in early May. Now, I already knoew that, but I’m grateful for the reminder. Thanks.

How funny. I was just going through some seed packets and was thinking I better get these guys going in the window or I’ll miss out entirely come April!
