Root intrusion is a problem that can be prevented using 3 different practices, listed at right. Following any of them will help. Using all of them will assure a lifetime of protection.

1. Use Netafim Techline since it is the ONLY subsurface irrigation product designed with a physical root barrier proven in most resistant to root intrusion in tests conducted by the renowned Center for Irrigation Technology (C.I.T.).
2. Apply a little water every day. If you run your Techline system for 5 minutes a day, it will help keep the drippers flushed and the soil moisture consistent to that the roots do not seek additional water.
