Tulsa Lawn Care Update – Time to Seed Fescue!

Tulsa Lawn Care Update - Time to Seed Fescue!




It may not seem like it, but next Tuesday, September 22, is the first day of fall. This is the perfect time to make plans for seeding fescue in bare shady areas or overseeding existing fescue areas. Mid to late September through October is the optimal time range for seeding.


Fescue is a cool season grass, so fall is the beginning of its growing season. Fescue is heat intolerant which is why we grow it in the shade in the Tulsa area. However, it does need sun. (In cooler climates, fescue grows in full sun.) By seeding in the fall, the new grass will soak up plenty of sun when the leaves fall off the trees, thus making it possible for the grass to store necessary carbohydrates to make it through the hot summer next year.


Even if you already have fescue in a shady area, you must overseed it every fall to keep it full and healthy. Hot summer temperatures always kill off some of it, and if you don’t overseed every fall, your fescue will thin out.


NOTE: You cannot grow fescue in an area with NO sun – like behind a shed, or between two houses.  For alternative options in full shade places, see our page on Shade Areas.


If you plan on doing your own seeding, please see our Fall Fescue Seeding page for instructions.


If you don’t want to do it yourself, we would be happy to give you a free estimate for overseeding your fescue. Just give us a call at 918-344-5737 or fill out our Free Seeding Estimate form online.


Weird Weeds?


This year we have seen LOTS of weeds and some strange weeds we haven’t seen before. Unfortunately, the repeated heavy rainfalls we experienced in the spring broke down the pre-emergent’s effectiveness early, so weeds have been worse than usual.


Rainstorms that lead to water rushing through ditches and over lawns are often responsible for distributing weed seeds. Unfortunately, weed seeds can remain under the soil and stay viable for decades! Weed specialists have actually found weed seeds 600 years old that they were able to germinate. Yikes!


Rain and wind also move weed seeds from your neighbor’s yard to yours, or someone’s yard three blocks over. The fact that we have seen weeds this year that we don’t normally see is probably due to rain and wind.





Doveweed is a weed that is not often seen in our area, but has been popping up in people’s yards, including my own back yard under a large tree.

And what is this stuff? I’ve never seen it in my lawn or gardens before, and this year it was everywhere! It grows vertically and entwines itself around fences, around other plants and trees. I have also seen tons of it just sticking straight up out of my yard and my neighbors’ yards.







Enough about weeds!  It's almost time to get some fall colors in your garden.  You might have noticed that everyone has pansies for sale!  Planting time for pansies in our area is when the soil temperature is between 45 and 65 degrees.  We are in USDA zone 7A, so usually the best time to plant them is late September or early October.  If you plant them too soon, they will get leggy without many blooms and develop a weak root system.  Some people wait until spring to plant them, but the spring flowers will be more bountiful if you plant them in the fall!


Mums (Chrysanthemums) are also a great fall flower and you can buy them in pots at any nursery or even at the grocery store!  Mums come in many varieties and can be perennial or annual.  If you are thinking of planting them in your garden, I highly recommend reading this Chrysanthemum article on HGTV's website.  Very informative!


Just a reminder -  your lawn needs 1 to 1 1/2 inches of water per week!  Rain has been a little scarce lately, so turn on the sprinklers if you need to.  Happy seeding and planting!
