REMOVING CLIPPINGS:   We mow our Bahia grass twice a week leaving about 3 to 4 inches.  However much we mow it, the clippings are always in excessive amounts.  Is it okay to leave the clippings?  Some or none?   Palm Beach County

ANSWER:  It's okay, probably beneficial, to leave the clippings on the ground, provided they don't smother the top of the bahiagrass.  If you do smother the bahiagrass, you'll know it because smothered areas turn yellow within a couple days, just from shading.  A little of that will weaken the grass, a lot of that will kill it.
Getting a mass of bahiagrass clippings to actually penetrate to the ground is difficult, but continuing to cut twice a week should help keep the clippings in a size range that they can sift downwards and act as a weed restrictive mulch.  Regular mowing also wards off invasion by various weeds, especially broadleaf weeds.  While a "mulching" blade may also help cut and recut the leaves to smaller fragments, which is good, mower deck design is also very important.  Some mower decks make for a good even spread of clippings, which easily slips into the canopy.  Other deck designs create windrows, which you definitely don't want unless you plan to rake anyway.
There are two other considerations.  First, will your client will accept esthetically the "let the clips fall where they may" approach?  Second, is there a serious weed problem?  Removing  clippings potentially reduces the spread of weeds, as was shown once for St. Augustinegrass.  So if your bahiagrass has a serious weed problem, especially in young, newly established areas, and if it's actually feasible to remove clippings, that would be worthwhile.
