By the planting guide here they are a spring planting and harvest is approx 5 mths later. You are wanting to grow out of season. Frosts will probably kill them. Plants do not grow much in July August. I don't like your chances of succeeding. USA is opposite to us in seasons that is why they have them in Oct.
