Vegetable gardens and orchards - Irrigation

In many cases, rainwater isn’t sufficient to water your plants and trees. Also, sandy soil can make water drain much faster than it should. A garden irrigation system is a good way of keeping your garden area moist at all times.

Begin by digging out some soil and placing it in a bucket of water. Let it moisten and then squeeze it in your hand in order to determine if it is sandy or clay soil. Clay soil will hold up in the shape you make it, while sandy soil will crumble. You need to place the tubes and emitters of the system closer together in sandy soil than in clay soil.

Next up you must dig small ditches just a few inches deep and wide enough so it can hold the drip tube in place. In clay soil, the ditches should be 18-24 inches apart, while in sandy soil, they should be 12-18 inches apart.

Unroll the drip tube in the ditch and cover it with mulch to help the soil around retain moisture more efficiently. Next, you must attach emitters to the tube. First make holes in the tube and then place the emitters inside the cut holes. Make sure the emitter is in a proper place before cutting it’s spot.  You can always add more emitters. A 15 feet tree requires 2 emitters to irrigate it. Each plant needs a couple of emitters 12 inches away from the plant base and once it grows, the number of emitters must be raised to 4 and the distance between them and the tree trunk, raised to 2 feet.

Use plastic T connectors to connect the drip tube to the main water source. The connector is snugly inserted into the tube, assuring a tight connection that won’t let any water seep out. Connect the a filter, a pressure regulator, a back flow preventer and a timer to the house that leads from the main water source to the drip system.
