trying grapes in this sunny spot against a stucco wall

trying grapes in this sunny spot against a stucco wall. should be a good micro climate. it was just sand, so I added about 8 composted straw bales, 2 wheel barrows of soil, 2 more of old wood chip. then fifteen varieties of grapes. what a job, been thinking about it all summer. will get trellis or arbour once they get established. hah and probably get thinned if they all survive. #grapes are both hard and easy to grow here, just need the right location
