Kind of a crazy question here...when we install fall/summer annuals they're typically long beds, 3 foot deep or so. After we plant we've always gone back and poured the pine chip mulch between the plants to mulch. This is always an awkward process, with plants at 8"to 12" centers sometimes chips get dumped on plants, it's hard to control the thickness of the mulch...I've been toying with different ways of installing the mulch, a different way to apply them. I've tried putting them down first, and then planting...that didn't work real well, now I was thinking of making some sort of "application spout" with black pipe. Does anyone do anything different, anything that works real well?
