Talkback: Planting asparagus crowns

Thanks for an informative video
I live in western australia, on the coastal plain, very poor sandy soil, needs improving plusplus plus
water logging as in your heavy soil is not a problem, quite the reverse, the soil can become very water repellent.
In this soil type, after improving with manure and compost, would it still be necessary to plant asparagus crowns on a ridge, as per th video
Many thanks for your info
