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 for your area...

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

Garden interest??

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.

Blog pimping is posting to FR with a link to your personal blog in an effort to generate traffic to your site.

Lots of peeps do it - some more subtly than others.

Feel free to join the conversation @ the Weekly FR Gardening Thread - which posts on Fridays.

I came across this site via a link on the site of our local TV garden show, The Central Texas Gardener. I really could care less about what type of fabric to use when making new curtains, and information of that nature, so quite a bit of this site does not interest me. But, I did find some of the gardening specific information useful. I realize it may not be The New York Times, but like I said, I found some of it useful and not readily available on the other sites I read regularly. Most a link be from The Wall Street Journal to post on FR?

No. you are doing just fine orson. Never mind what the other guy said. It is not blog pimping to post a link to a website if it is not for personal gain.

“Feel free to join the conversation @ the Weekly FR Gardening Thread - which posts on Fridays.”

I usually read this thread every Friday, should I wait until this thread comes out each Friday, and then post any Gardening related article inside that thread? I’m not trying to be a smart a_ _, I just want to make sure I follow protocol.

Good information. Thanks for posting.

[eastforker]

I believe you owe orson an apology!

[Just mythoughts]

Thank you for the find and the thread. It seems the TSA mentality is not limited to airports.

[Just mythoughts]

Thank you for the ping.

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.

Good information. Thanks for posting.

That guy is wrong; ignore his insult. This is NOT “blog pimping.” This is useful information. Thanks for posting.

[FreedomPoster]

We have a number of Barney Fife types over-zealously policing blog posts. They’re really obnoxious in many cases for no good reason other than their own self-importance. Please ignore them and, if they get too obnoxious to you, tell them to ef-off.

lol @ Just mythoughts

Thanks for the info, orsonwb, was about to ping the garden list keeper to spread the wealth but it’s already done.
