I'm preparing my first backyard vineyard very small only 24 vines with a 6x6 spacing I used a dig-it and turned over all the soil and plan on planting in 2 weeks, the former owners of my house must of loved rocks, I have an abundance of large river rocks threw out the property and my question is this once the vines are in would it be advisable to place the rocks in the aisles....this would be purely aesthetic for me as I'm not really worried about weeds because it's not a big area but would this harm the vines in any way
