Tulsa Lawn Care Tips for March: Snow, Henbit and Spring!

March roared in like a lion this year and gave us a dose of ice and snow and some sub-teen temperatures!  How does that affect your lawn and landscape?


Actually, extreme cold temperatures combined with recent drought conditions can be very bad for your bermuda grass, causing winter injury and sometimes killing areas of grass that are thin or in somewhat shady areas.  The good news is that we were very lucky to have snow, which acted as insulation for the grass, so everything should be fine!  And we definitely needed the water!  If you already had your first pre-emergent application, the snow watered it in for you!


Spring henbit

But if you’re seeing a bunch of purple flowers in your lawn, you’ve got a case of henbit!  Henbit can be very invasive, although it’s relatively easy to eliminate at this stage.  In fact, the pre-emergent application we’re doing right now also contains a post-emergent to treat the henbit.  It may look out of control now, but it’s fairly easily controlled with this application!  Just remember: in this weather, the henbit will not turn brown and look dead!  And it certainly won't disappear.  You must mow it off, and then it won't come back.


We’ve been getting some halfway nice days with temps in the 50’s and 60’s and some good sunshine.  Don’t be surprised if you start to see buds on shrubs and trees, and you’re probably already seeing your daffodils and other early spring bulbs popping up.  Is spring almost here?


Well, yes…but don’t get overanxious! Spring fever can hit hard after being cooped up all winter, but hold that thought for a little while, yet.


I’m as guilty as the rest of wanting to get out there and start cleaning up flowerbeds and planting things, but we could still get a cold snap and wintry weather!  DO NOT scalp your bermuda lawn yet!  But if you want to plant pansies, that’s okay!


And if you want to blow the leaves off your fescue, that’s a very good idea!  Remember, your fescue may not look its best right now, but it needs that sunlight while it’s still cold, before the leaves come back on the trees.


In Tulsa, the average last date of freezing temperatures is March 29.  The record low temperature is -3.  Record snowfall is over 19 inches.


So, we aren’t clear of winter just yet!  Just hang in there, be sure to get your spring pre-emergent applications so you don’t have a weedy lawn this year, and dream of spring flowers! And if you aren't a GreenGrass customer yet, get a free estimate!


Oh, and if you can get out there and water your lawn, please do so!  It's been VERY dry.  If not, hope for some much-needed spring showers!  (Hopefully, without any tornadic activity!)

6 Tips for your Tulsa March Lawn Care List

Doesn’t nature just blow your mind, sometimes? It’s amazing to me that La Nina can bring us blizzards and minus 13º weather like last year, and then spring in February this year.  She changes her mind like a 4 year old in a candy store!  But…we are nothing if not adaptable.  Here’s what you need to do now.


Be patient!  DON’T scalp your bermuda or zoysia lawns yet.  We know it seems like winter is gone, but remember where we live.  We recommend scalping your bermuda or zoysia lawn between April 1 and April 15, after the last frost.  If you scalp it down now and we get a cold snap, the roots of your grass could sustain damage.


Scalping your lawn is simply putting your mower on its lowest setting, mowing, and bagging the clippings. (For bermuda & zoysia ONLY, not fescue.)  This removes all the dead grass and allows the sun to warm the soil faster, letting the bermuda green up more quickly.  Read more mowing tips.


DO mow if you have already had a pre and post-emergent weed control application (like we are doing now,) and there are weeds in your lawn.  Okay, you don’t HAVE to start mowing already.  But if you just started service with us (or any lawn care company) and you have a pile of henbit and dandelions in your yard, go ahead and mow it at the regular height.  Henbit has been prolific this year with the warm weather coming so early and the bermuda still dormant.  The lawn care application killed them, but they won’t disappear. (Note: don't mow directly following an application; wait at least 24 hours, then water, then mow, in that order.) If you mow them off, they most likely won’t come back.  And if you didn’t get an application yet, it still helps to mow them before they seed.  You don’t need more viable weed seeds floating around.


Get your crabgrass pre-emergent down.  It’s time for your first crabgrass pre-emergent, which needs to be put down before the crabgrass germinates.  With the unseasonably warm temperatures, that’s not far off!


Water, water, water.   I know we’ve had a few rains, and maybe you were lucky enough to get more than a drizzle or a 5 minute downpour.   My yard is definitely not one of the lucky ones.  Nobody likes to water this time of year – you don’t want to drag out the hoses, or de-winterize your sprinkler system yet.  But your lawn needs it.  Little moisture plus high wind = your lawn drying out.  And the bermuda IS beginning to green up (if you look way down there at the soil line, you’ll see it.)  It’s starving!  Give it a drink!


Prepare for the season.  Sharpen your mower blades, change the oil in the mower, check your weed wacker and edger.  Be ready when you need them!


Don’t rush out and start buying flowers and cool stuff to plant (unless you buy pansies!)  Personally, I spend an egregious amount of money on flowers and cool stuff every spring.  Can’t help myself!  But I have learned that even though it might be fine to plant annuals now…then again, it might not be.  ALWAYS assume it won’t be.  We could still have a cold snap.   And many of the annuals we plant, like caladiums, don’t like the cool nights, even in the 50’s. It’s kind of like buying a cool zebra plecostomus fish for your aquarium.  These fish prove that there’s a great plan to nature, because how else could anything be so beautiful?  So, they come from the Rio Zingu basin in the Amazon, and they cost a whole bunch of money, and the first night you have this extraordinary fish in your aquarium, the red-tailed catfish eats it.  Snack!


That’s what might happen to your flowers and plants if you plant them now.  Just saying.
