Grape vines in clay soil?
I planted some grape vines last year and I dug maybe a 2 cubic foot hole and mixed in compost and clay. The rest of the soil around it is clay. I have been reading this isn't very good for grape vines. My grape vines seem to be doing well this year though and I'm wondering if they will continue to do well or if the clay will do them in? I'm planting a new one tomorrow is there any better way to prep the soil? I'm going to make the hole much larger with more compost/clay mix.
The varieties are Thompson an flame seedless.
