For the smaller areas of the garden, micro irrigation is your answer. Micro tube, micro sprays, or micro drippers will allow you to water areas of the garden where pop-up sprinklers and fan sprays are just too big. Micro sprays mounted on micro risers are actually quite discreet, and being much slighter than other irrigation types, they can be placed throughout the garden without taking away from the overall look of your garden. Micro irrigation also works out to be very cost effective, and it’s easy to install, so where possible, we recommend it as a great way to water your garden.

Thereโs no best type of sprinkler, just better sprinklers for different applications. Gear Drives are better for large areas, over 5m. Pop-Ups are ideal for 1.5-5m & Micro sprays are excellent for anything under that.
You can simply use Micro Drippers or Micro Drip Tube, but your challenge is delivering the water to the pot. We suggest you run Poly Pipe as close as you can & then thin Micro Tube as hidden from view as possible up into the pot.
Each sprinkler & nozzle will push out water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler youโre looking at uses & work within your flow limit. For more information, check our Product Guides.
As you install a system, itโs almost inevitable that small fragments of dirt will get into the pipe, for this reason you should always flush out the system before running it the first time. This can be done by leaving an open end at the farthest point of each irrigation zone & operating the zone for 15 or so seconds to flush it out. Then plug it up & youโre good to go! This can also be said for any other times dirt may have gotten into the system (eg: further irrigation repairs or a mains water supply fault).
We definitely donโt recommend it. Typically, drip tube will deliver the water at a far slower rate that sprays. Because of this, if you were to have both on the same zone, the areas with drip would be left far drier than the areas with sprinkler coverage. If you do want to water some areas with drip & some with sprinklers, it can be done, but each will just need to be run on their own separate irrigation zones.
Due to the different flow rates or each type, itโs often not recommended. A micro spray will typically provide water at 1-2lpm, where as a fixed micro dripper will provide far less, at 2-8lph. However, there are adjustable drippers which can provide higher flows & there are applications where you may want less flow, like pots or native planting.
Each spray & dripper provides water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler youโre looking at uses & work within your flow limit. For more information, check our Product Guides.
Firstly, each sprinkler &/or nozzle has a specified spray radius. Secondly, sprinklers are typically designed to deliver more water at their base & progressively less the further away you get. For this reason, you want to position sprinklers so they spray to hit the base of the next sprinkler. Of course this isnโt possible all the time so in those cases, aim to spray at least 80% of the way. By doing this you will guarantee even water across your lawn or garden.
Because of their small outlets, micro sprays can block from time to time. Fixing individual sprays can be as simple as unscrewing them & simply blowing the blockage back out. To avoid repeat blockages we recommend installing a simple inline filter.
Even on a typical domestic system running on mains water a filter is still a good idea. In the event of a water main fault where rubbish does find itโs way down the line, a filter will protect the system from blockage and or failure. On systems operating off recycled water, like from a tank, a screen filter is mandatory. Debris like silt & dirt from recycled water is the most common cause of blockages of failures in irrigation systems.
