Drip irrigation for hedges and shrubs: design and installation

Emitters and layout

Drip delivers water to the active root zone, cutting consumption 30–50% vs overhead spray. Foliage stays dry, reducing fungal disease.

Use pressure-compensating emitters (2 or 4 l/h) for lines over 30 m. Single-row hedge: 16 mm poly tube parallel to stems, emitters punched directly in. Always fit a 120–200 mesh filter upstream.
