Good to hear you're shelving the roundup idea. I suggest saving all your shredded leaves from this Fall and put them on the beds over winter. The snow thaw freeze back and forth helps break them down some more, and they serve as great mulch/weed barrier that also helps the soil as they break down into compost. When your leaves are fully decomposed hopefully you'll have a nice batch of grass clippings saved over Spring/Summer to add to your beds as needed. I like a nice 4" layer. This too decomposes into a nice soil additive and I rototill the whole thing after our first hard freeze and start all over again. Turned 100% hard tack clay into a sweet loam in about 4 seasons that way. 100% natural and super effective.
