Average Date for Last Killing Frost

Be Careful!!!

Okay, Okay....... This is a picture of early February and not mid March, this particular climatic event followed up on the heels of a previous freeze and was particularly damaging to many, many woody ornamentals and most soft tissue plants. Do not, I repeat, do not freak out, there will some topical freeze damage, but the plant will grow out of it soon. Minor trimming, proper watering, with sunshine and you will be amazed the strides your plants take this spring. But what about my grass??........Well..... all vegetative growth will take off when the ground temperature maintains 65 to 68 degrees...that is ground temperature.

Be aware we could still have another killing frost, I cannot tell you how many times I have been on bike rides on April 1st when it was freezing and sometimes even snowing. So be patient and if not, then watch diligently and be prepared to protect your new plantings.
According to some maps for Dallas, the average last frost date varies even within the city, with some neighborhoods having a last frost date from March 1st through March 10th; whereas, some neighborhoods in North Dallas have a last frost date of March 10th to March 20th.

Remember that these are averages!!! If you look at historical data for my zip code on, you can see that my area has had a freeze as late as April 13th., but then I live in Mckinney.

Spring  is almost in full stride......enjoy the life......
