    On what kind of grass? Fine on fescue, not very good on warm season species. Too much pre-m not enough N and K.

    Even on fescue, I do not see enough potassium. Fortunately, it is hard to hurt fescue with Pre-M. The difference between a lawn that looks good under most circumstances and one that gets stressed easily is often the K and micronutrient levels.

    I'm here in 1' of snow in TN away from the coast. What is that 1.5oz of K? Do you mean 3.0 and 1.5 of Pre-Em per K(1000 sq ft of area) or Potassium (K). If so, it does not read that way. Are you using a liquid or granular mix on the fescue? I'd get a soil test and go by the recommendation on the amount of fertilize. As for the pre-em--Barricade has less root pruning than Dimension. There are some decent granular mixes but do leave holes in the turf. Any turf as Greendoctor advised needs Potassium to make it hardy for the winters here, strengthens the root system. Generally, an application 1/2lb of Potassium/1000 sq ft. every month using a liquid. Gallery-a great liquid pre-em has the least root pruning effect. In any case follow the directions on the label and a split application is good for fescue. Just watch you ground temps. When the soil temp is about 50, it is time to use your pre-em. Much after that to about 55 or so is too late as the weed seed will start to germinate.

    I assume there is more fertilizer in the form of nitrogen and potash than your chart shows. A small amount of potash in each treatment is a good bet. Potash is soluble and tends to wash out during heavy rain or sprinkling--particularly if soil is low in organic matter.

    Hey, thanks for the reply... It is 3oz per 1000 sq ft.... What stood out to me was that was the fact that there is a lot of weed control but lean on feeding the grass??? Maybe I am wrong on that?? The info above is what was given out to the customer on the receipt. That is ALL they are putting down and it is in the liquid form, except for the last application.

    sorry for the confusion, all those (K)s are per 1000 sq feet not potassium... thanks!
