First, I use a drop spreader rather than a rotary spreader since I don't want the herbicide to hit the plantings bordering the yard.
So here is my paradox. The Scott's weed & feed says to wet the lawn before using (presumably so the herbicide granules can stick to the weeds better). However, when I wet the lawn, some wet grass inevitably ends up running against the drop-feeder slit which causes the fertilizer to cake-up and clog the slots.
In summary:
- If I don't wet the lawn first, then it spreads but it doesn't stick to the weeds, so the herbicide doesn't work
- If I wet first, then the drop spreader slits clog and I get neither fertilizer nor herbicide action (or I end up opening the slits wider by some random amount and get a random, uneven coverage)
So, what am I doing wrong and what should I be doing?
