A well-designed irrigation system makes it easy to keep your garden healthy and thriving. Whether you need broad coverage for garden beds or targeted watering for individual plants, installing sprayers and drippers is a great way to ensure even and efficient watering. Follow these steps to set up an irrigation system that suits your garden’s needs.
Safety tip: Always wear the appropriate safety equipment (safety glasses, gloves, ear muffs and a mask, for example) and always follow the instructions for the product or equipment.
Before installing your irrigation system, decide whether sprayers or drippers are best suited for your garden. Sprayers are ideal for larger garden beds, as they distribute water over leaves and topsoil, providing coverage for plants with broad foliage. They come in full, half, and quarter-circle spray patterns, as well as different spray styles, from a fine mist to larger droplets.
Drippers, on the other hand, deliver water directly to the base of plants, making them a more efficient option for deep-rooted plants. They are also ideal for windy areas, as the water goes straight into the soil rather than evaporating or being blown away. Depending on your garden’s needs, you can use a dripper hose for widespread coverage or install individual drippers for targeted watering. Most irrigation systems are designed to be discreet, with the tubing hidden under soil or mulch to maintain a neat and tidy garden appearance.
To install garden sprayers, start by laying out the 13mm poly tubing along your garden bed, making sure it reaches all areas that need watering. Use a hole punch tool to make small holes in the tubing at the desired locations for your sprayers. Insert a rigid riser into each hole, then screw the sprayer onto the top of the riser. Sprayers should be positioned to provide even coverage across your garden bed, ensuring all plants receive adequate water.
If you need to navigate corners or split the water flow, use elbows and tees. Elbows allow you to make smooth 90-degree turns around garden beds without kinking the pipe, while tees let you branch off to different sections of the garden. Once your sprayers are in place, secure the tubing with garden pins to prevent movement over time.
For targeted watering, drippers are an excellent choice. To install them, start by punching a hole in the 13mm tubing and inserting a 4mm barb fitting. Attach a length of 4mm tubing to the fitting, then position the dripper at the base of your plant. Drippers are particularly useful for potted plants, vegetable gardens, and trees, as they deliver water directly to the roots.
If you have plants with varying water needs, consider using adjustable drippers. These allow you to control the water flow for each plant, ensuring they receive the right amount of moisture. Once all drippers are installed, cap the ends of the 13mm tubing using end fittings and connect the main line to your water source with a snap-on tap connector. Turn on the water and check for any leaks or dry spots, adjusting the drippers as needed.
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
