How to Control Dollar Weed in St Augustine Grass Lawn
by Rick Orr Winter 2012
The waxy glossy green leaves of dollar weed present themselves just above and horizontal to the mowing plane of the lawn – making dollar weed one of the most visible and noxious weeds in a St Augustine grass lawn.
But that highly visible leaf is only a small part of the problem because dollar weed lives primarily below ground - about 90% of the plant is below ground. So, killing the leaf does little to control the plant!
Winter Challenge: Keeping Tropical and Sub-Tropical Landscapes Alive in Cold Weather
Winter 2012
The trick to keeping tender plants safe from cold weather is knowing the limitation of your plants and your options to protect them from cold weather. Most plants grown in Pinellas County require temperatures below 28° for several hours to be damaged. Why? It is the freezing of water in the plant cells that kill plants – not the actual cold weather. The water in the plant cells freezes at 28° - not 32°...
Dollar Spot Disease Forms Straw Colored Dead Spots in St Augustine Lawns
Winter 2011
Dollar Spot is a very common disease of St Augustine lawns in Pinellas County. I see it on nearly every lawn. Dollar Spot is not a serious threat to your lawn - it is more cosmetic - effecting the appearance of your lawn. Dollar Spot is a low fertility disease and is certainly increased because of the fertilizer ban forced on Pinellas County by SWFWMD.

St Augustine Lawns Look Better When Mowed with a Sharp Mower Blade
by Rick Orr Fall 2011
St Augustine grass always looks better when mowed with a sharp mower blade. The St Augustine grass leaf contains rigid cells made of a very tough plant material that is difficult to cut. Mowing St Augustine grass with a dull mower blade creates a frayed tip

Grand Opening: Gallery of Lawn Art
Fall 2011
You know, sometimes I take life too serious – bugs, weeds, fungus, oh my! and I have to remind myself to “lighten up”. Often it is the little gnomes, whirly gigs and other little pieces of lawn art I see during the day that remind me to do just that – lighten up, Rick!
THis is a collection of my favorites. Enjoy
Irrigation, Water and St Augustine Grass: Healthy, Weed Free and Green Lawn - Just Add Water
by Rick Orr Fall 2011
The picture shows a leaking irrigation pipe keeping the soil moist near the leak. The St Augustine grass above the leak is healthy, thick, green and weed free. The St Augustine grass beyond the leak is brown, weak, thin and weedy. The difference being - water! If you want a healthy, weed free, GREEN lawn, water as much and as often as law permits.
What to Do When Weeds are Taking Over Your Lawn
by Rick Orr - A Promised Land Lawn Spraying Fall 2011
“Weeds are killing my lawn” or “My lawn is being overtaken by weeds” are the most often heard complaints about weeds. But the truth is weeds don’t kill a lawn and don’t smother a lawn. Weeds do have seasons when they grow faster than the St Augustine turf and seasons of maturity (weeds are at their maximum size) that make them appear to be getting the upper hand on your lawn. But the truth is St Augustine turf is far more aggressive than common weeds and will kill and smother the weeds.
Brown Patch is a Cool Weather Disease in St Augustine Lawns
Fall 2011
With the cooler temperatures and wetter soils, Brown Patch is active in lawns in the Pinellas County area. Brown Patch is a common turf disease that occurs in the Spring and Fall during cool (not cold) temperatures. The pathogen is a soil born fungus and can not be eliminated, but with some good culture can be reduced. Some lawns, because of the type of St Augustine and the soil, have chronic problems with Brown Patch. Distinctives are circles or joined circles of brown grass with a “halo” of yellow grass .
