Any system that generates a low volume of water is classified as a micro-irrigation system. Typical micro-irrigation systems include drip, trickle and some spray heads. Micro-irrigation is ideal for small areas of plants whose foliage cannot be sprayed. The water supply drips or trickles from plastic tubing close to the root, never touching the plants' leaves.
This system is high maintenance, however.
Tubing is often covered by mulch or plant foliage and the orifices can easily become clogged.
Even the most diligent gardeners might not realize a clog in their micro system until the affected plants begin to show signs of stress.

If not properly laid, the tubing can be unsightly and is easy prey for mowers and vandalism. The tubes are also known to break in freezing weather.
The use of a professional in your irrigation project doesn't mean that you cannot play an active role in implementing your new system. The four irrigation systems are only the beginning, and research on valve types and controller options will go a long way to ensuring that you receive the irrigation system that works best for you.
