Whether you’re growing roses to win prizes or just trying to keep a few flowerbeds looking good, you know what a chore watering is, lugging hoses around the yard and moving them every half hour or so. Micro irrigation—a network of plastic tubing and low-volume drippers and sprinklers that reach every part of the garden you want to water—takes the hassle out of watering.
The materials are inexpensive and easy to install using nothing more than a pruning shears and a special hole punch tool. Once you lay out the tubing and connect the drippers, sprinklers or sprayers, you’ll be able to water your plants by simply turning on the water and letting it run for an hour or two. Add a battery- operated controller and you won’t even have to remember to turn on the water. It’ll turn the water on and off automatically at the times you select.
Micro irrigation saves more than time and energy; it saves water by distributing it more efficiently. Because you use dozens of watering devices to replace one regular sprinkler, you have much greater control over where the water goes and how much is supplied to each plant. Instead of flooding the ground all at once, micro irrigation lets you apply a small amount over longer periods, allowing it to soak into the plants’ root zone for maximum benefit. And since runoff and evaporation are kept to a minimum, micro irrigation uses less water.
In this article, we’ll introduce you to the basics of micro irrigation, including planning tips and step-by-step installation instructions. For more details, especially in the planning phase, we recommend that you also read through one of the manufacturers’ free planning guides or browse relevant internet sites.
