Question about Growing Potatoes in Straw
I'm considering growing the potatoes in straw, instead of soil. Has anyone here ever done that? In "Lasagna Gardening" the author says this results in smaller spuds. What do you think?
Straw is definitely cheaper for me than using potting soil (I don't have enough decent garden soil to add it to my tower), but if it makes much of a difference in yield, I'd rather go with soil.
Thanks for your advice!
