[QUOTE="Mark Reynolds, post: 1837072, member: 43196"] I'll get to the fescue in my next post here. First, the broomsedge. Lime USUALLY takes care of the broomsedge and yes, the pH is the FIRST thing to correct. The reason the broomsedge is prevalent is that there is a lack of AVAILABILITY of phosphorous and/or potassium. When the pH of a soil is low, phosphorous and potassium that is in the soil simply is not available to the plants because of the pH. Correcting the pH makes these nutrients available. If your pH is fine (6-7) and you still have a broomsedge problem, then the soil is lacking phosphorous and/or potassium. These need added with fertilizer at this point. If you attempt to fertilize without correcting the pH, you will still have broomsedge because, even though you added the 'missing' nutrients, they still aren't available because the pH i 'blocking' them or rather binding them and preventing their availability. A soil test will answer the pH and nutrient availability/quantity questions. [/QUOTE]
