ASK IDA

How do drip irrigation systems work?


Dear Ida B. Green,

I'm wondering if drip irrigation would work for some of my gardens and if I can just add it to my present system.

Signed, Dripster

Dear Dripster,

When choosing where to put your new drip irrigation lines, consider which beds might benefit most from the advantages this system offers.

Garden beds bordering buildings, pavement or fences benefit by eliminating overspray of your irrigation water onto these non-growing surfaces and causing them water-related damage.

Drip systems deliver the water to the soil where it can soak directly to your plants' roots without damaging foliage or being lost to wind and evaporation.

Drip works great if you have problems with low water pressure.

If your yard is like mine, this means every garden bed, tree or shrub would benefit from a drip system and only lawn areas need to be sprayed.

To get started, ask for information at your favorite nurseries or from your lawn-care company. Some things to consider as you design your new, water efficient system:

- You can retrofit some of your present irrigation zones to accommodate drip lines or you can design completely new drip line zones and systems.

- Although drip needs lower pressure than most spray, you may be able to change any spray heads on the same zone as your gardens to low-pressure spray heads.

Keep it Green,

Ida
