A Time to Sow…Fescue!
When and how to sow Fescue.
By Paul James
One of the most popular gardening activities this time of year is sowing the king of cool-season turf grasses, namely fescue, from seed. It’s practically a ritual for folks who’ve come to realize that if you want a thick stand of the stuff, or if you don’t want to stare at brown Bermuda grass all winter, you pretty much have to put down seed. And thankfully, it’s a pretty simple process.
Sow Now Through Octoberish
The optimum soil temperature range for sowing fescue is between 50 and 65 degrees, which is generally associated with air temps of between 60 and 70 degrees. However, it’s perfectly fine to get a jump start on planting as long as you water well both before and after the seed germinates. (Soil temps this week in Tulsa County have been in the 70s.)
Stick with Blends
It’s best to use a blend of seeds that contains only tall fescues, or one that contains tall fescues blended with fine fescues, Kentucky bluegrass, or even ryegrass in varying percentages, rather than rely on a single variety. I’ve tried dozens of blends over the years, and while I’ve seen subtle differences in them, I truly believe that the best way to choose one over another is a coin toss.
Prep the Area
Mow the existing lawn before applying seed, and get rid of sticks or leaf litter. Use a steel garden rake to rough up any bare spots. Once that’s done, you’re good to go. Some people think you should also aerate the lawn beforehand, but unless your soil is extremely compacted, you can skip that task. Besides, once the seed falls in the holes left by the aerator, the lawn often winds up looking like a bad hair transplant.
If you’re seeding bare soil, the application rate is 10 pounds of seed per 1,000 square feet. If you’re overseeding an existing lawn, cut that rate in half.
Keep it Moist
The most important consideration when getting seed to germinate is even moisture, because dry seed simply will not sprout. Typically, that means watering every day – even twice a day — to keep the top ¼-inch or so of soil moist. Do that and you should see germination within seven to 10 days, 14 at the outside.
Once the seed has germinated and the grass blades begin to grow, it’s time to fertilize. (Prior to germination, the embryo of the seed contains all the nutrients necessary for the seed to germinate.) I only use all-natural fertilizers because they tend to release their nutrients slowly over time, but that’s just me.
You Gotta Mow!
A big mistake people make is getting so excited about how well their grass is growing that they forget to mow it. Once the leaf blades are four- to five-inches tall, give the lawn a haircut, but don’t remove more than a third of the top growth to avoid stressing the young turf.
