The past few weeks I’ve spent most of my time visiting lawn after lawn and talking with customers about what’s wrong with their grass. In North Texas, we had one of the coldest winters on record, and it did a LOT of damage to St. Augustine. What a lot of people don’t realize is that St. Augustine is a tropical plant, and is usually very aggressive. My normal recommendation is for our customs to be patient, and the grass will fill back into freeze damaged areas soon.
This year is different. We had a HARD winter (record setting hard.) So hard in fact, that I’ve seen a few lawns nearly wiped out from freeze damage. Thankfully this isn’t the norm. Most of the lawns I’m visiting will fill back in once we have some warm weather and rain, which you’d figure we’d have by May 20th! Amazingly a lot of lawns are still partly dormant at this time of year which is highly unusual. Lawns come out of dormancy when the soil temperature reaches 65 degrees to a depth of 4 inches. To get there we need night-time temperatures that are consistently above 60 degrees, which hasn’t been happening in North Texas. Just last week we were getting down to the low 50s at night. Yes we’ve had 90 degree days but not enough of them in a row to cause the grass to grow strongly and all lawns to come out of dormancy. I’ve even seen some neighborhoods where one side of the street was about ¾ dormant and the other side was about ¾ out of dormancy. My best guess is the other side got a little more sunlight and did better. Strange days indeed (to quote John Lennon). My bet is we’ll actually see some warm weather soon (it is Dallas after all.) In fact, this past week or so I’ve noticed that a lot more lawns are finally coming out of dormancy and growing like they normally would have in April. This means that a lot of that winter damage we’ve been seeing should start going away over the next few weeks.
While you’re waiting on Mother Nature to warm up, you can make sure you are watering your lawn properly for the spring (download our FREE watering guide.)
In the spring your lawn requires around a half an inch of water per week on average. That equals roughly 30 minutes for most sprinkler systems. The problem we have in our area is our infamous clay soil can only absorb about 10 minutes worth of water. After that it will run off which is not good for your water bill or our local water supply.
Our advice? Don’t water all 30 minutes at once. Instead program your sprinkler’s controller to water one day per week with a start time of 2am, 4am, and 6am, having each zone run for 10 minutes.
If you have rotors (the type of sprinkler that turns slowly while spraying a long thin stream) you need to water twice as long (at least 20 minutes per zone at 2am, 4am, and 6am.) Depending on the rotor speed and stream, you may need to water even longer to give your lawn what it needs.
