Make sure to sharpen your blades before the first mowing- Dull blades cause "tearing" of the blade which causes the tips to have a brown discoloration. In addition, it is not healthy for the plant. Ensure that used blades are free of cracks, nicks or bends before using them.
2 1/2-3" Mow height (1st mowing only)- This will remove the old tips and encourage new growth resulting in better vigor and appearance. Height should be moved to 3-3 1/2" for subsequent mowing(s).
Change directions- This is important to releive compaction and to reduce stress from heavy traffic on turf in localized areas.
Too Mulch or Bag?- Decomposed mulched clippings go back into the soil as organic matter making for a better overall turf. It is not true that mulching causes compaction.
