Step 1
Draw a sketch of your trickle irrigation pattern as you go. Using a clipboard is handy so you can carry it with you and make notations.
-
Step 2
Measure the distance of hose you will need. Do this by laying string along the path you want to irrigate. Your string should rest alongside the root balls of your plants. This will be the design your tubing will follow later so make sure the string travels to each plant you want watered.
-
Step 3
Determine how many emitters you will need by leaving the string in place, and making a mark with a colored marker by the root ball of each plant. Count the marks and record the number.
-
Step 4
Count the number of "V" connectors you will need. A trickle system has pressurized water in the hose so once the entire system reaches top pressure the emitters at the end of the hose will drip as well as the first section. Use "V" connectors every place you need to branch off a hose in a different direction. If you're designing a straight pattern, the hoses will connect end-to-end.
-
Step 5
Figure out how many end caps are needed by counting the ends of each hose. Some trickle hoses come with caps; if not, you will need to buy them. Capping the end creates the pressure in the irrigation system.
-
Step 6
Calculate the final hose length by stretching out the strings, after labeling each one with a twist-tie and a tag and noting which one it is on your drawing. Store the strings carefully; you will use them later when you assemble your system.
-
Step 7
Design a cover for your trickle system. Your lawn will hide a low-lying hose that you secure to the ground with clips, allowing you to mow over it at a high mower setting. Consider placing organic mulch around specimen plants to cover the hose and help retain moisture.
