Water when necessary and rake occasionally As a general rule the grass clippings should be removed each time you mow If weather conditions are dry and hot and the grass is weed free leave the clippings on the lawn to help maintain ground moisture August Keep mowing regularly and watering as necessary Fill any cracks caused by drought with a mixture of sharp sand and soil In dry weather conditions leave the grass longer to help retain ground moisture September Raise the height of cut to allow the grass to thicken and protect the roots from the winter frost and snow October Rake out the thatch from the turf and spike the lawn to assist in drainage Brush in peat and sharp sand November Use a stiff broom to disperse worm casts before mowing Keep turf free from leaves December Apart from brushing away leaves December is a slack end of a busy year Keep off the lawn if it is very wet or frozen Lawn Stripes The way to achieve a neat striped effect is for the lawn being cut in parallel stripes alternate stripes being mown in opposite directions A much more important routine is to cut at right angles to the line of the previous mowing If the work has been carried in a north south line then the next cutting should be in an east west direction The cross cutting keeps down the coarse weed grasses To prevent grass damage do not remove more than one third of the grass height in one cut TROUBLE SHOOTING 1 Engine
