noun sub·ir·ri·ga·tion \-ˌir-ə-ˈgā-shən\
Definition: irrigation below the surface (as by a periodic rise of the water table or by a system of underground porous pipes)
I love to garden but my vegetable garden has always been a source of frustration. This is mainly due to the parade of unwanted guests who devour the fruits of my labors. I live in a suburban neighborhood. Most of my neighbors are not that into gardening so their yards consist of a few foundation shrubs and the occasional perennial with a few annuals thrown in. As a result everyone comes to my house for lunch. To solve this problem, last fall I had an enclosed garden "pen" built.
There is a lot of information out there about these kinds of systems. This is how I did mine.
First I dug out some of the soil from the bed and leveled the bottom. I then lined the bed with pool liner up the sides and stapled it on. The pool liner I bought was bigger than I needed. With the first one I folded the excess under but that was not the best idea. With this one, I trimmed away the excess and it worked out much better.
You also need a system to make sure the holes in the pipe do not get clogged with soil. For my first bed, I used sheets of porous landscape fabric which I laid over the top of the pipes. This worked but was difficult because the bed was wider than the fabric so I had to use 2 lengths which shifted a lot when I was putting in the dirt.
Use the fill pipe to fill the bed with water. You will know it's full when you see water coming out of the drainage hole. Be patient, it takes a lot of water!
I found a milk bottle cap that fit over my PVC fill pipe so I don't have to worry about getting dirt in the pipes.
This bed was large so I added a bridge. You don't want to walk on the bed since you could damage the pipes underneath.
Have a fun day!
