This was our first attempt to make a vertical garden. Our choice of materials for this experiment in vertical gardening was to create a rain gutter garden system in which to plant leafy greens, radishes, and a few herbs.
The first tip: Manage your water.
I'd intended to set up a soaker hose system that connected to a garden hose on the top tier and snaked down to the bottom tier.
If each gutter is 10 foot long and it's 2-3 above one another, and there's a 25 foot soaker hose, there won't be too much wasted length.
