Last year I tried something a little different and tilled the garden, furrowed it out for planting then covered with weed barrier, cut the holes and planted the plants or seeds, then covered with wood chips to shield the plants from the heat reflecting from the barrier. I think it worked pretty well for holding in the moisture and keeping the weeds at bay. Do you think I need to pull up all the barrier and till again, then lay it back down and start over? Anyone have better steps?

no... don't till again.... pull back your mulch of wood chips, lay down a layer of compost around your plants and put back the mulch....the compost will leach goodness down thru the barrier and feed the plants and soil and the mulch will still be there to help with weeds and temperature and moisture..... the few weeds that do appear will be easy to remove..... my foundation beds are done this way.... and in spring and fall I do the compost/mulch thing to keep the soil happy.... has done me well for quite a while now.....
