Garden Drip Irrigation Tutorial - How to add drip irrigation to a raised garden bed
We are often asked for tips on installing drip irrigation for raised bed vegetable gardens. Garden drip irrigation is very forgiving and you have many options to choose from.
Here is one approach to a garden drip system. Modify it to fit your garden.
Example: 3ft x 8ft raised garden box
Upgrade Your Drip Hole Punch & Save Time
A clean cut makes it easier
Some drip irrigation hole punches are shaped like a pencil and simply poke a hole as they push through the drip irrigation tubing. They require more force and can slip off of the drip tubing before they make the hole. The Super Punch (shown here) has a squeeze handle and is only $9.90. A less expensive option is our Deluxe Hole Punch which has a sharp, circular cutting edge. This drip irrigation hole punch is comfortable, easy on your hands, and costs only $3.90.
A Paper Clip Quickly Cleans a Hole Punch
Insert the wire to clear the tool
A good hole punch will actually cut a tiny circle out of the drip irrigation tubing. The plug of drip irrigation tubing can be removed from the cutting edge of the punch with a paper clip. Push it through the cutting end to clear any plastic debris.
Fix Little Holes With a Goof Plug
Doubles as a 1/4" end plug
If you make a mistake and poke a hole in the wrong place on a drip line, insert a goof plug (small barb). If the hole gets worn and leaks a little, pull the plug out and use the large barbed end. Goof plugs are also used to plug the end of 1/4" micro tubing.
Adjust Water Flow to Garden Boxes With a Flow Control Valve
1/2" Valve fits over mainline tubing
These drip irrigation valves are great when you have garden boxes or drip areas that you may want to turn off seasonally. You can reduce the flow or shut it off completely. 1/2" Flow Control Valves are installed just like a compression coupler.
Fix Big Holes With a Coupler
If a goof plug won't do the trick
If you have a hole in a mainline poly pipe that is bigger than a goof plug, a compression coupling is the fitting to use. Make a clean cut and insert the two tubes into each end of the coupler. No glue required.
Threaded End Caps Make Winterizing Easy
Unscrew cap to flush or drain drip tubing
