Materials Needed

To install a drip irrigation system, you will need the following materials:

• Poly Tubing: This is the main tubing that connects to your water source and distributes water throughout your garden. Common sizes include 1/2-inch and 1/4-inch polyethylene tubing.
• Adapter: An adapter is used to connect the poly tubing to your water source, such as a hose bib or outdoor faucet.
• Backflow Preventer: This device prevents dirty garden water from flowing back into your household water lines, ensuring a safe and clean water supply.
• Barbed Fittings: These fittings connect the poly tubing to the emitters or sprinklers, ensuring a secure and leak-free connection.
• Filter: A filter traps particles that could clog the emitters, ensuring that the water flows smoothly and efficiently.
• Pressure Regulator: This component regulates the water pressure to ensure that it is within the optimal range for your drip irrigation system (typically between 10 to 30 psi).
• Small Stakes: These stakes are used to secure the tubing in place, preventing it from being damaged or disturbed.
• Watering Devices (Emitters/Sprinklers): These devices distribute the water to the plants. Emitters are small nozzles that release water slowly into the soil, while sprinklers provide a broader coverage area.
• Timer (Optional): A timer allows you to automate the watering schedule, ensuring that your plants receive water at the right times.

Overview of the Drip System

A drip irrigation system is a network of plastic tubing and low-volume drippers or sprinklers that deliver water directly to the root zones of plants. This method of irrigation takes the hassle out of watering by providing a consistent and efficient way to deliver water to your plants.

Planning Your Drip Irrigation System

Before you start installing your drip irrigation system, it's essential to plan it carefully. Here are some steps to help you plan your system:

1. Measure Your Garden: Measure the area of your garden to determine how much tubing and emitters you will need.
2. Choose Watering Devices: Select the type and flow rate of the watering devices based on your soil type and the plants' water needs.
3. Determine Tubing Route: Draw a simple sketch of your garden and mark the tubing route to connect the emitters or sprinklers.
4. Start Small: If this is your first venture into micro irrigation, start small and experiment to get a feel for how the system works.
5. Customize Your System: Add a few extra emitters or sprinklers to your system so that you can adjust it as needed.

Step-by-Step Installation Instructions

Step 1: Prepare Your Materials

Before you begin installing your drip irrigation system, make sure you have all the necessary materials. Lay out all the components on a flat surface to ensure that you have everything you need.

Step 2: Connect to Water Source

Connect the poly tubing to your water source using an adapter. If you are using a hose bib, you can attach a hose splitter or four-way manifold to handle multiple attachments.

Step 3: Lay Out Tubing

Lay out the poly tubing along the edge of your garden bed or lawn. Use small stakes to secure the tubing in place, ensuring that it does not get damaged or disturbed.

Step 4: Connect Emitters/Sprinklers

Connect the barbed fittings to the emitters or sprinklers and attach them to the poly tubing. Make sure that the emitters are spaced evenly and that they are not clogged with debris.

Step 5: Add Filter and Pressure Regulator

Add a filter to trap particles that could clog the emitters and a pressure regulator to ensure that the water pressure is within the optimal range for your system.

Step 6: Test Your System

Turn on the water and test your system to ensure that it is working properly. Check for leaks and adjust the emitters or sprinklers as needed.

Step 7: Automate Your System (Optional)

If you want to automate your watering schedule, attach a timer to your system. This will ensure that your plants receive water at the right times, even when you are not around.

Types of Drip Irrigation Systems

There are several types of drip irrigation systems available, each with its own benefits and applications:

Soaker Hoses

Soaker hoses are hoses with holes spaced evenly along their length. They can be placed alongside row crops, hedges, shrub lines, lawns, or vegetable gardens. These hoses seep water slowly into the soil along their length and are flexible and easy to use. However, they are not suitable for use on slopes and may not be the best choice for food crops due to some varieties being made of recycled rubber.

Emitter Systems

Emitter systems are becoming more popular due to their efficiency and ease of use. These systems consist of small hoses with evenly-spaced nozzles (or "emitters") that slowly drip water into the soil. They are excellent for keeping small shrubs (such as roses) or trees watered efficiently throughout your landscape. Emitter systems are useful during long periods of summer drought and can be set up in various configurations to suit different garden layouts.

Drip Tape

Drip tape is the most economical option among drip irrigation systems. It is easy to install and use but only works when set up in straight lines. This system is an excellent choice for annuals and vegetable gardens as it can be buried or covered with mulch. Drip tape is flexible and can be adjusted as needed, making it a versatile option for gardeners.

Micro-Misting Systems

Micro-misting systems are devices that can be attached to your irrigation hose system. They are ideal for large trees on your property and can also be used for flower beds, ground cover areas, hillsides, and slopes. These devices disperse water slowly and evenly over root zones, benefiting shallow-rooted shrubs like rhododendrons, azaleas, and hydrangeas.
