This is going to be my second year at attempting to do the whole square foot gardening thing. I have plenty of room to grow enough for my whole family or at least I hope. But I wanted to try my hand at growing vertical this year to get even more. I am looking for ways to grow my veggies vertically that are easy, cheap and won't be an eye sore to the rest of the neighborhood. Does anyone out there have any ideas they care to share?
