Tulsa Lawn Care Reminder – WATER!!
And Watch out for Poison Ivy!


Mother Nature was pretty generous with the precipitation this spring, but the arrival of summer seems to have dried up our rain prospects.


We are seeing lots of crunchy lawns out there as well as cracks in the soil, which are  sure signs that your grass needs water.  The temperatures are up and so are the winds.  Windy weather dries out your lawn and landscape in a heartbeat! 


So…high winds, no rain and temperatures in the high 80’s. Please give your lawn a good soaking!




Bermuda grass loves hot weather.  When the low temperatures are in the 70’s or above, bermuda will grow 24 hours per day, as long as it gets enough water.  If it doesn’t get enough water it will become drought-stressed, turn brown and go into premature dormancy.


If it does get enough water (and sun, and proper mowing,) it will grow fast and thicken up as it spreads.




Fescue grass hates hot weather. If you have fescue in your lawn, you must water it deeply twice per week, and you may need to lightly water it daily just to cool it off.


Your fescue grass spent last fall and this spring soaking up the sun it needs while the leaves were off the trees.  Now, it doesn’t have much sun, and it is living off its stored carbohydrates.  If it doesn’t get sufficient water, it will die. 


Note:  if you planted fescue in full sun, it will die in this heat.


Your lawn needs one to one and a half inches of water per week.  Please click here to read about proper watering.




Don’t forget your trees, especially young trees!  Trees are much slower to show symptoms of insufficient water, and young trees are more vulnerable than older trees.  The smaller the leaves on the tree, the faster it will decline without enough water.  Species like river birch, dawn redwood, cypress and willows all need a lot of water.


The bad thing about trees is that by the time they show you the symptoms – wilting leaves, yellowing leaves, leaf drop, premature fall coloring - they could already have sustained serious damage.


During drought periods, slow, deep watering (put a sprinkler under the tree) every 4-6 days will keep mature trees happy.  For young trees or newly planted trees, water every 2-3 days.




Be careful of viney things you don’t recognize in your garden, growing up the side of your house, or on a tree trunk or fence.  Even if you think you know what poison ivy looks like, did you know there are lots of different kinds of poison ivy, as well as poison oak and sumac?


I strongly urge anyone who spends time outside to go to the website below and take a look.  They have FAQ’s and pretty much all you ever wanted to know about poison flora, plus a quiz to see if you recognize the different plants.


The MAIN THING you need to know if you think you touched poison ivy is to immediately wash the area with high-pressure COLD WATER (like from a garden hose.)  Do not use hot water, or you will spread the urushiol oil that causes the rash, as well as open your pores, making your skin absorb the oil faster.
