Paul We grow sunflower with our yard-long beans in North Louisiana to redirect stink bugs .... they grow well together here as the soil does not need anything different ... Marigolds grow well to help with the horn worms ....

We would like to grow sunflowers for my daughters wedding in late February 2018, I am in Auckland. When would be the best time to plant them? I will buy the young plants from a garden centre I think. We are going to grow them on a friends large property out in Whitford. They may get some wind. Also they are rabbits on the land?? Many thanks
