First let me start this thread letting you guys know I am Home Owner DIY kind of guy. I read a lot of threads on here and take in as much knowledge as possible. So here is my question... I want to make sure I use this Celcius WG product correctly. Because I know improperly using this stuff and I could destroy my lawn. I had a irrigation system installed April 25th roughly, and when they trenched the yard I think they awoke a sleeping nightmare of crabgrass. This is a new home and the Tifton bermuda was laid Dec 15th 2011. I went to the Local John Deere landscapes and he recommended the Celcius for my problems. The crab grass is my largest problem but i have random other weeds throughout the yard. I notice on the product label to treat crab grass i need to use .113 oz per 1000sqft. I have a 2 gallon pump sprayer and 8000sqft of grass. I am somewhat confused on how to mix it. The measuring cup is odd...it has 1,13 oZ but not .113 and the cup has a comma next to the 1 not a decimal point. would that be .113 oz line? Should i only spot treat or blanket my entire yard? I laid new sod in the trenches 32 days ago, it has all rooted, is it Safe? Should i mow before treating or after? I need to apply fert, does it matter when i do it with this treatment? The weather is very hot down here right now, is there a certain time of day I should apply this. I read alot of other threads saying they use a surfacant, is that necessary? if so is Hi-Yield spreader sticker a proper product. http://www.fertilome.com/product.aspx?pid=2d96ab93-df5b-4d76-be77-fd4669e0c890 Have I forgot anything important? I would provide some pictures to help, but it is not letting me upload any photos. here is the product label if you dont have it in front of you http://harrells.com/wp-content/harrells-products/label-images/CELSIU.pdf Thank you all of your help is greatly appreciated.
