I have a lovely raised bed (about 12 foot diameter) which houses what's left of a lawn. The bed is half shaded by conifers, half sunny. The grass does not grow too well in the shady area, so I would like to do something else with this site. I would like to make it into a wildflower bed, or use it as a veggie plot for larger veg that I can't put into containers, such as broccolli, squashes and sweetcorn. Can anyone advise what may be best for this site?
