Some say that it is best to only grow on male plants, and these can be identified as the ones that don’t produce the berry-type seed in late summer. As seedlings in the final bed can be extra work to remove, also no energy is wasted by the plant in seed production by male plants
Prepare the asparagus bed well as it will be in production for many years to come. Fork in as much organic matter as you can, digging it deep .
