Tulsa Lawn Care April Update – Poa Annua and Soggy Lawns

Tulsa Lawn Care April Update – Poa Annua and Soggy Lawns




At this time of year, the bermuda grass is beginning to come out of dormancy and starting to green up.  But, bermuda likes hot weather and lots of sun.  If our rainy, cloudy weather pattern persists, it may take a little longer than usual.

The fescue grass, on the other hand, is looking fabulous!  Fescue thrives at this time of year because the leaves are not fully out on the trees yet, so the fescue gets plenty of sun, and the temperatures are still cool. 

We’ve had a lot of rain this year already, and you may have a soggy lawn, or even standing water, especially in the ditches, depending on how good the drainage is in your neighborhood.  This is a big pain when you’re trying to mow without making ruts in the lawn!  If you have excellent drainage, lucky you!!


April Fescue Grass




With the amount of rain and soggy lawns, grassy weeds are going to be a problem this year.  Poa annua  (also called annual bluegrass) likes moist soil, and we have seen a ton of it!  Nutsedge may be a problem as well because it is a water grass.  Sometimes it seems like weeds come out of nowhere, but wind and rain scatter weed seeds everywhere!

Proper mowing procedures are extremely important to weed control.  You should mow often enough that you don’t have to bag the clippings.  (And we know that’s not possible when it’s raining every day! )  Please visit our “Mowing” page for more information!





The shape your yard was in when you started our program will determine how quickly your lawn will respond to treatments.  It would be really nice if one or two applications would get rid of all the weeds, but unfortunately that is not likely!  Please be patient with your lawn.  You should notice an improvement with each application.  Also, when we treat weeds, they will not just disappear.  In cooler temperatures, they may not even turn brown.  Even though they don’t look dead, they are. 


We encourage you to visit our “Your Lawn” page for information that will help your lawn look great! 


Thank you all for choosing GreenGrass Lawn Care!  Take care, and be safe!


Don’t forget to go outside on Tuesday April 7 at 9:35 p.m. to see the Supermoon, the biggest full moon of the year and also the Paschal Full Moon, which is the first full moon of the spring.




Wilfred says that if you are stressed out, or really bored,

you should plant some flowers!

GreenGrass Tulsa Lawn Care Update – Scalp Your Lawn & Other Tips for Spring!

Tulsa Lawn Care Update

Scalp Your Lawn & Other Tips for Spring!


Spring has arrived, bringing with it all the lovely downpours resulting in mushy lawns and standing water!  But the warmer temperatures, sunshine and rain are making everything grow like crazy, including the weeds.




You’re probably seeing masses of purple flowers (henbit) everywhere and lots of dandelions.  These are broadleaf weeds, and the application we are currently applying contains a post-emergent weed control to take care of the ones present in your lawn.  Also included is the second pre-emergent for crabgrass.  (Unfortunately, there is no pre-emergent for broadleaf weeds.)


Please remember that after we spray your lawn for weeds, they won't just disappear!  With the cool night temperatures, they may not even turn brown.  They will have stopped growing, though, and once you mow the lawn, they will be gone.  





Here are some things you can do now to make your yard look its best!


Scalp Your Bermuda Lawn


As soon as the weather permits, set your lawn mower on its lowest setting, mow your bermuda lawn short, and bag up the clippings.  This will allow the sun to more effectively heat up the soil and make your lawn greener faster.  Bermuda loves hot weather.  Scalping is for bermuda grass lawns ONLY.  Do NOT scalp your fescue grass. 


Mow Your Bermuda Lawn Frequently


Many people mow on a schedule, like once per week.  But the grass needs mowed when it needs mowed.  If it looks like it’s getting high or you can see weeds going to seed, mow it.  Mowing frequently is a great deterrent to weeds, and it encourages your bermuda to grow sideways and spread out, giving you a thick, lush lawn. See our Mowing and Scalping page for more info on proper mowing procedures.


NOTE:  Mowing and watering properly can make a huge difference in how good your lawn looks!  Mother Nature has your back on the watering for a while, so be sure to hold up your side with the mowing!


Keep Leaves and Debris Off of Fescue Grass


The fescue grass is looking fabulous at this time!  Fescue is a cool season grass. In the Tulsa area, we plant it under trees in the shade where it’s cooler and where bermuda won’t grow.  But fescue needs sunlight, too!  Right now, it is loving our cool temperatures.  The leaves aren’t fully on the trees yet, so it’s soaking up the sun as well.  It is imperative that the fescue get the sun while it can, so it can store up carbs to make it through the hot summer when it’s in the shade again.




Don’t Trim Your Trees and Shrubs Just Yet


A rule of thumb is to NOT trim your trees and shrubs when leaves are forming or falling.  You especially want to refrain from trimming any trees or shrubs that are spring-flowering like hydrangeas or azaleas.  The best time to prune spring-flowering shrubs is after the blooms start to fade, shrivel and discolor.  If you prune them too late in the summer, you will be cutting off the limbs that produce the flowers.  There may be exceptions for certain plants, so it’s best to look up whatever plant you want to trim before you do it!



The redbud trees are blooming beautifully!



Have You Seen Any of These Flowers?


Do you see any of these pretty little flowers peeking out of your flowerbeds?  If so, dig them out in a hurry!!  They are wild violets, and they will multiply faster than bunnies!!  They are extremely invasive and will get into your lawn, too!




Do You Have a Fairy Ring in Your Yard?


A Fairy Ring is usually a circle or arc of mushrooms.  I noticed one in our lawn last year, for the first time.  Fairy rings can last a REALLY long time.  There are some in Europe that are 2000 feet across and over 700 years old. 


However, you can still see the fairy ring even if the mushrooms aren’t there – the grass around the fairy ring is a different shade of green and is growing faster than the rest of the grass, as you can see in the picture.




What causes them?  Why, fairies dancing in the circle, of course!


Nah, it has to do with mycelium, fungus, hyphae, spores and enzymes…but I won’t bore you.  Rather fascinating, though!





Wilfred is quite anxious to get the shade garden cleaned out since the ferns and wild ginger are doing so well already. He also wanted to remind you that each time you refer a friend to GreenGrass, and they take the full program like you do, you get $50 free credit on your account!  Yay!  Read the details here.

Tulsa Lawn Care Update May 2015 – Weed Control, Rain, and Patience

Posted by Kathy Wilder on Fri, May 08, 2015 @ 05:06 PM


Spring is in full swing but it doesn't always go the way we want it to! 

Bermuda Progress - To put it mildly, Tulsa lawns are a little behind this year!  Many of our customers are calling and wondering why their bermuda lawns haven’t fully greened up yet.  You can thank Mother Nature for that because, as usual, she’s in charge.

 My bermuda 

Bermuda likes hot, sunny weather, and it needs full sun to grow.  So, it’s behind at this point.  All our rain days have added up to little sun and lots of water.  On one hand, the bermuda isn’t all pretty and green yet.  On the other hand, you probably haven’t had to water your lawn yet!  (And our lakes and reservoirs have benefited immensely.)


But don’t panic!  Bermudagrass is amazingly resilient.  Every spring our unpredictable weather throws us a curve in one way or another.  In a few weeks, with some consistent hot sunny weather, your bermuda will be thriving!


Weed Control – for our brand new customers just starting out, we’d like to ask you to be patient with your lawn.  We’ve had new customers calling 2 weeks after their first application, saying they still have weeds.  Weed control takes time.  If it just took one application to get rid of all your weeds, we would just do one application!  The wind and heavy rainfall that we’ve been having will deliver fresh weed seeds to your lawn on a daily basis.  With the bermuda not fully out yet, it’s open season for the weeds. 


If you had a lot of weeds to start with, you will see an improvement with each application – however, if your lawn was pretty weedy to begin with, it didn’t get that way overnight, and we can’t fix it overnight…much as we’d like to!


If you have bare areas with no grass, we cannot keep the weeds out of it.  That’s simply a law of nature!  Putting a piece of sod in a bare area is the best solution. 


To help with the weed control, be sure you are mowing properly.  I understand that mowing schedules have been wacky due to the rain, but please see our mowing and scalping page here.  Mowing properly is one of the best ways to have a thick, healthy lawn, which will help immensely with weed control, because it will crowd them out.  If you haven’t scalped your bermuda lawn yet (bermuda, NOT fescue) please do so as soon as the rain and soggy-ness allows.


And since a thick, healthy and vigorously-growing lawn is your best defense against weeds, the situation will improve greatly when the bermuda is fully greened up.


Spring Dead Spot – SDS is rearing its ugly head, as it always does in the spring.  You will recognize it as spots in your lawn that just don’t green up at all.  It is most visible this time of year.  To learn more about SDS and ways to help your grass grow over the dead spots, please see out Spring Dead Spot page here.


That’s all I’ve got!  Here’s hoping everyone stays safe during our tornado season!  If you have any questions about your lawn, please give us a call, or email us here.
