And different plants require very different methods of irrigation that deliver the proper amount of water to keep them healthy. Matching the right type of sprinkler head to certain groups of plant species will optimize your Water Use Intensity. This perfect match will also prevent overwatering, which will damage your plants, and prevent wasteful runoff.
Each different sprinkler head will water your plants in the particular way they like. Choosing the right sprinkler system design for your lawn will depend on the size of your lawn, and also the water pressure your irrigation system design operates on. These sprinkler head types work best for small to medium-sized lawns, as they distribute water evenly.
If your water pressure is between PSI, spray head sprinklers should be placed no farther than 15 feet apart, but with overlap for full coverage.
Placing spray heads farther than 15 feet apart would create dry spots in your lawn. Spray irrigation heads put out a lot of water fast and give a fine, misty spray that can be blown away.
The exact size depends on the type of sprinkler head that you buy. For example, a head that you attach to your hose may protrude off of the ground anywhere from a few inches to a foot or more. Many sprinklers can be adjusted in height so that you can tailor them to your needs.
It is common for sprinkler heads to settle into the ground over time. Think about this when you choose the height of your sprinkler head. If you need a minimum of 4 inches of clearance to reach over a bed, consider getting a six-inch head or even longer, to account for some settling.
If the head settles too much, you can raise it up with a little bit of digging and repositioning. This section of the guide will help you get an idea of what kind coincides with the landscaping that you are working with. Your watering needs may be different for various sections of your yard. These distinct areas can be thought of as zones. In general, it is best to use only one type of spray pattern per zone.
Souce: Lowes. For a small to medium yard, pop-up sprinklers with fixed spray patterns would work well. The limited throwing distance is not going to be an issue because you have less space to cover.
Another option may be an above-ground hose attachment. For zones of a small yard with planters, you may want a micro spray pattern that will focus on that immediate area.
Large yards or commercial sites. If you need to cover a large area, consider gear driven rotor heads because they are quiet and can include a maximal throw distance of up to 55 feet. However, some newer models can cover rectangular areas. If you have an irregularly shaped yard, a circular head may work well. But for regular yards with many even, straight edges, the rectangular patterns cover the most area without overlapping.
Think of your yard in terms of zones. These areas will have plants of like types. For example, one zone might be the grass-covered lawn, and a second zone may be a flower garden in front of the house. Once you divide your yard up into zones, it is helpful to know how much water each zone needs.
Irrigation experts will often talk about the GPH that each head can deliver. This acronym refers to gallons per hour. For example, a food garden might need twenty gallons per week, and a lawn may need less. Do some research online or consult a landscaper to figure out what your plants require. Next, you will need to discover the square footage of every zone.
This information will help you decide what kind of heads to buy, as well as how many you will need. This is useful information to know because it will tell you how far apart your heads will need to be position so that you create head-to-head coverage in the zone.
Consider the climate that you live in as you shop. The precipitation rate that the sprinkler is capable of delivering tells you if it is going to be sufficient for watering your plants. A plant with an extensive root system, like a tree, that is in a hot, dry climate may need more inches per hour IPH of precipitation than a small plant in a rainy or humid environment.
The cost of a sprinkler head typically ranges from about thee dollars to almost twenty dollars per head. This price range has to do with the variations in how the body and nozzle designed.
A simple hose attachment with few moving parts will be less expensive than a large turf rotor with many small, exposed moving parts.
If you find sprinklers for lower prices, such as one or two dollars per head, make sure that it includes both the body and the nozzle. Sometimes these items are sold separately, which accounts for the lower price. When buying your sprinkler head, think about not only what kind of head will match your needs and be right for your budget, but also maintenance. Is the appearance of your landscaping vital to you? If so, be sure to think about aesthetics as you choose your sprinkler system.
Some options have sleek, refined profiles, while others are bulky, or rustic in appearance. Some manufacturers include key features that enhance the product. Here are some examples to features to look for. Source : Amazon.
If water conservation is important to you, look for devices that can work with a rain sensor. While some brands support this type of device, others do not. If your yard has sections that require specific patterns, such as a narrow spray pattern of fewer than 40 degrees than you should look for spot-specific spray patterns. One particular design that works well for tight areas is an end-strip pattern. Due to the slower precipitation, rotary heads tend to lead to less runoff which means less wasted water when compared to traditional spray heads.
To learn more about rotary heads watch this short video by Hunter Irrigation. See our selection of Sprinkler Rotors here. Bubblers: Designed for delivering a lot of water fast in small spaces like tree basins or around shrubs and ground cover. These are not used to water lawns. Avoid using bubblers in places that are not level or has soil that does not drain quickly i.
If you have an extensive landscape that you wish to water we strongly recommend installing a drip irrigation system instead of lots of bubblers.
Drip systems are much more efficient for large landscapes. Note: Whether you use bubblers or a drip irrigation system, both should always be placed on their own zone and not connected to the same irrigation valve that runs the spray heads or rotors. Having everything on one zone seems like a good idea, however; it will result in over watering some plants and under watering others since the applications are so different.
To learn more about installing a drip irrigation system for landscapes check out the video below. Can your irrigation system supply 40 PSI of water pressure?
If no, then we recommend using spray heads since they can function at lower PSI. If yes, then rotors are the way to go. Provided you have enough PSI. Does your lawn have curved borders? If yes, you can use rotors if the non grass area is okay to be sprayed like a flower bed. If the area should not be sprayed borders a house or you wish to minimize overspray for water conservation purposes then go with spray heads.
Do you have a few shrubs or trees to water outside of your lawn? If yes, then incorporate a few bubblers into your design. If you have more than 3 of such areas to water then consider installing a drip irrigation system.
