What can you grow in a Grow-Box

Anyone grow asparagus in soil BOXes? I was concerned withoverwintering using the sawdust/sand as soil. Is this a veg that mustbe grown in actual soil? And along those lines - what about onionsand garlic - can these be grown in soil box "soil" as well?Appreciate anyone's experience here. Thanks!"

Group:All the vegetables you mention - and pretty much anything else - can be grownwith success in the Grow-Boxes using sawdust and sand as the soil mixture.
