Here in Ukiah, an old Italian farmer friend lived next door with a half acre in grapes for personal use. He used dried out grape seeds to mulch that he wanted to look nice and be walked upon (like an alternative for pavement or grass). The vineyard was planted such that its foliage spreads overhead to form a shade layer (much needed here in the summer). The grapeseeds below look like little black stones and kept back weeds. A table and chairs were set underneath.
