Landscape irrigation is a way to keep your garden thriving with just a simple system. The system is just sprinklers or soaker hoses that you lay throughout your garden. When that is done hook up the hose and turn on the water, but if you want to keep the plants moist longer put mulch around the base of the plant. There are different types of mulch so I recommend you look at what could be best. Put the mulch on top of the hose so that the water does not have to soak through the mulch to, and you are done with your system.
