How to Micro Irrigation

If you dread the task of watering your flower beds by hand or dragging a sprinkler around and you want to conserve water I have the solution for you, it's called micro irrigation and it's inexpensive and diy friendly! I have built two complete systems, one for my former house and one for a friends house and not counting the labor (mine!) the total cost of each system was under one hundred and fifty dollars and my friend had a large amount of flower beds and shrubs.

Things You'll Need

  • micro irrigation parts
  • shovel dig trenches to bury line

      I suggest that to start measure the length of garden or plant beds your going to irrigate. This will give you an idea of how much main distribution pipe that you need for your watering needs. Then buy a variety pack of emitters and various fittings you need to get started, these are wonderful for experimenting with different outlets hook of of main line. The type of emitter used will be determined by the type of plant and how the plants are arranged in their beds.

      Lay the main polyethylene half inch line out from your hose bib to your flower beds trying to keep the line centered in the plant bed.. Determine what emitter placed directly on the main line would water which type of plants.
      It's really easy to attach these emitters by using the punch tool that comes with the variety pack. Punch hole into the main line where you want the emitter, then push the barb on the emitter through that hole, it's a simple and quick process. Make sure you anchor the main line down with the "u" shaped wire hold down brackets.

      Once you have put various sprinkler or emitter heads on the main half inch line you might have to branch off further to reach both sides of the flower bed. Do this by running a quarter inch line off the main line with a barb adapter attached through the hole made with punch tool. From here we can run this line to more remote areas that might be reached better with a sprinkle pattern that sprays in a quarter or half circle, use the unique spray pattern of each emitter to your advantage to cover the most plants as possible or to hit one lone plant way off the side.

      Be careful how much line you use the pressure could drop too quickly making the end emitters weak or non functional refer to directios that come with the pack of emmiters to determine max lengths of the main lines. Also you need to use inline filters to avoid obstructions forming in the line. One of the neatest things you can do is install a timer on your system that comes on and goes off automatically and if you really want it all they make a rain gauge that turns the timer off thus saving water when it rains.

      Use hose bibs on the one side of the house for flower beds and plants and approach the other side of the house until you mesh with the system coming from that sides hose bib.Using both sides hose bibs gives you adequate pressure for the system to work properly. There are no hard fast rules here the type of plants and terrain will determine how your system is created, just play with each type of emitter until you know what it does, but you can always pull one out and replace it with a different emitter head.

      If you have plants in pots use little drippers that attach to the quarter inch lines so they feed directly into the pot, even pots that hang off front porches can use hidden lines that feed down into containers, as with all the emmitters you can customize the water flow to this individual hanging plant- use what you need and compared to sprinklers or hand watering it's a very water conscious system.
