The Top 10 Most Frequently Asked Questions About Drip Irrigation

Drip irrigation is the most efficient type of irrigation, in which water is applied slowly to plant roots via a network of tubes. It is a popular choice among gardeners and farmers for its effectiveness, as it can save water and reduce water expenses compared to traditional watering methods. Drip irrigation delivers water more uniformly, promptly, and precisely than any other irrigation method. This irrigation method minimizes water loss due to evaporation, percolation into the soil, and runoff by delivering water and nutrients directly to a plant's roots.

In this post, our irrigation experts answer the most commonly asked questions about drip irrigation by gardeners, landscapers, and farmers.

1. How Does Drip Irrigation Deliver Water to Plants?

Drip irrigation delivers water directly to the roots of plants using a network of drip tubes and emitters. The emitters gently release water in tiny droplets. The system gets water from a source such as a faucet, tank, or main water line. Then, the water flows through a main line tubing that delivers it to multiple zones. The main line connects to smaller sub-main or distribution tubing that runs along the plant rows. Emitters are attached to the drip tubing that delivers water in controlled drips or drops to the soil near the plant's roots.

2. What are the Benefits of Drip Irrigation versus Sprinkler Irrigation?

Drip irrigation is more water-efficient than above-ground sprinklers. Instead of spraying water over a wide area, drip lines moisten the soil around the plants. With drip irrigation, no water is wasted due to runoff, evaporation, or overspray. This method conserves water by directly watering the root zone.

In sprinkler irrigation, there is less control over how much water crops receive, and more water is lost due to evaporation and runoff. Drip lines also emit water at a slower rate, allowing roots to absorb more water over time. This reduces overwatering, which can cause mold on the plants and roots.

Drip irrigation benefits include:

• Saves water, money, and time
• Increases irrigation effectiveness on sloped or uneven ground
• Reduces water and nutrient waste
• Reduces weeds by applying water directly to the roots

3. Are there any disadvantages of Drip Irrigation?

The drip system installation process requires initial investment and careful planning. Drip Lines can become clogged if not properly maintained and filtered, resulting in breakages, leaks, and plant loss. The system should have a pressure regulator to manage pressure issues and a filter to prevent clogging. In addition, the surface tubing is prone to damage by rodents or tools and equipment.

4. What are the Two Types of Drip Irrigation?

Surface Drip Irrigation: It involves installing a drip tubing network above the soil surface and applying water directly to the soil surface.

Subsurface Drip Irrigation (SDI): This type of irrigation involves a tubing network placed below the soil surface, allowing water to flow directly into the plant's root system beneath the soil. The tubing is buried in the ground at 20-50 cm depth. It is widely regarded as an efficient method for reducing evaporation and conserving water.

5. What are the Main Components of a Drip Irrigation System?

The primary components of a drip system include:

• Drip tubing
• Emitters or drippers
• Fittings
• Valves
• Filters
• Irrigation controller
• Pressure regulator
• Backflow preventer

6. Where Can I Use Drip Irrigation?

Drip irrigation can be used to water shrubs, trees, groundcovers, flowerbeds, raised beds, hanging baskets, vegetable gardens, pots, and containers. It is ideal for landscape beds with various plants and shrubs rather than lawns. This low irrigation suits new and existing landscapes and vegetable gardens. It is also perfect for installation on uneven terrain, such as hills, irregularly shaped places, and high-wind locations. It can also be installed in a greenhouse or nursery.

7. How Long and How Often to Water Plants Using a Drip Irrigation System?

Drip irrigation schedule can vary depending on plant type, soil, climate, zone, emitter spacing, and water pressure. After one or two weeks of using the system, evaluate the soil and the health of the plants and adjust the watering times accordingly. Adjust watering based on the flow rate of your emitters and plants' needs. Generally, the system should run 20-60 minutes one to three times per week throughout the summer and 10-30 minutes one to two times per week in the spring and fall.

8. Can I Fertilize My Plants through Drip Irrigation?

Drip irrigation is ideal for fertilizing as the drip lines can deliver fertilizer directly to the root zone. Fertilizer injectors are efficient devices that deliver nutrients to your plants and promote their growth. You will not need to fertilize manually.

9. How will I know that the Drip Irrigation System is working?

After turning on the system for a few minutes, look closely around the plants to check where the soil is moist. There are various ways to verify that your drip system is working.

• Monitor water flow at the meter.
• Look for moisture or wet spots on the soil's surface below an emitter and around the plant's base.
• If the drippers are subsurface, connect the micro tubing to the dripline at any point (preferably at the end of the line) and bring it to the surface. At the end of the microtubing, add a dripper and use it as a point source emitter to ensure the system is operational.

10. How to Maintain a Drip Irrigation System?

A subsurface drip irrigation system requires seasonal maintenance. This involves regular flushing, cleaning filters, and checking for leaks or blockages. Inspect the system regularly to ensure it works flawlessly and evenly distributes water. Check emitters, valves, fitting connections, and tubing for leaks or cracks. Repair or replace the damaged component immediately.

Moreover, the system must be winterized in the fall before temperatures drop below freezing. When winterizing, turn off the water supply and blow air through the water lines to remove all of the water from the system and prevent damage from freezing. In the spring, the irrigation system should be restarted by turning on the water. Before starting in the spring, inspect the system, test it, and fix any problems.
