We have a few lawns in a particular neighborhood which are impossible to get the growing undercontrol. 4 houses in a a row, they all water, monthly fert. and just plain old super healthy kentucky bluegrass. Back at spring cleanup they were all cut at 3" as the grass was barely growing. As soon as temps warmed up within one week the grass with 6-7" and made cutting at anything below 4" brown the grass out and look terrible. Last year 4-4 1/4" seemed to be a good cutting height for the houses. This year it is impossible. lawn is growing 4"+ a week and even cutting with the deck all the way up still requires multiple passes and bagging. These are being cut with Lazer Z mowers with exmark high lift blades. Should I be swithcing to a different blade? I requested that they only water every other day, but even that has not helped slow the growth rates at all. These houses should be money makers having 4 in a row, however we spend way too much time there, double cutting and bagging.
