A well-designed layout considers: water source location and flow rate, garden size, plant water needs, sun exposure, soil type, and slope. Sketch your garden to scale on graph paper as the first step. Measure all dimensions and note obstacles.
What factors should you consider before designing an irrigation layout?
How do you divide a garden into irrigation zones?
Group plants by water needs: high (vegetables, annuals), medium (perennials, shrubs), and low (native plants). Each group becomes a separate zone. South-facing slopes need their own zone. Drip zones should never mix with sprinkler zones.
What pipe sizes do you need for your irrigation layout?
Main supply line: minimum 1 inch for systems over 10 GPM, 3/4 inch for 5-10 GPM. Lateral lines: 1/2 inch for short runs, 3/4 inch for longer runs. Drip lines: 1/2 inch for runs up to 200 feet. Oversizing pipe slightly costs little but improves performance.
How do you create an irrigation layout diagram?
Draw your garden to scale on graph paper. Mark the water source, valve locations, and zone boundaries. Draw pipe routes with straight lines.
Label each zone with water requirement in GPM. Keep the diagram near your controller for reference. Drip emitter types guide pc non pc adjustable Related: Sprinkler Head Popping Up But No Water Coming Out: Complete Fix
