I have to tell you right off the bat... I'm not a gardener; I'm a total newbie at this game, its just I'm sooo excited, I had to show you what we made at my house.
We bought some plastic gutters from the hardware store and my husband cut them to fit in our fence then nailed them. He also nailed a couple of little supporty pieces of wood underneath and drilled some drain holes in the bottom of the gutter. Super easy huh? The ends of the gutters are open but doesn't seem to be a problem since they fit right in fence panel.
Then we planted them with all different spices & herbs. So far so good, we had a serious rain since we planted and they held up.
This was a pretty cheap project, the plastic gutters were about $6.00 and it keeps our little dogs from eating (& tinkling on) all our plants:)
I'll keep you posted on how our garden is going - I would love to know if any of you have tried this or any garden tips, pictures :)
