Young SprinklerDaddy over at YouTube sums up the difference between spray and drip irrigation quite nicely:

SPRAY IRRIGATION Here a spray head is attached to a pipe for widespread water about 6′ to 12′ in all directions. “This method is good for watering a large bed of flowers or perennials that are all the same size,” says SprinklerDaddy. And lawns, he might have added. It is not suitable for a bed where there are different sized plants as the larger shrubs tend to block the water and the small shrubs get nothing.

DRIP IRRIGATION SprinklerDaddy really likes drip irrigation. He describes it as “cool.” He says: “This is for localized type of watering where you want to get water to the root of each shrub. There is no blocking out of smaller plants and no wasted water. It is a really good option when mulching. Once you have put down the bark or rocks, lay the pipes on top and cover with mulch. No need to dig a trench for the pipes.” And no need to watch the 1 min, 48 sec video either. All you will see is a talking head repeating what I have written above.

Somewhere down in Texas one winter, a man looked at the camera to tell us about the two types of irrigation you can use for your raised garden bed. According to the man with the winter grass stretching out behind him, compliments of ExpertVillage and YouTube, you can have Precision Button Irrigation (for directing water to a specific area) and Laser Drip Irrigation (for soaking a wide area).

Button irrigation involves small pipes leading off a main hose with a button at the base to control the flow of dripping water. Laser irrigation is a long, thin pipe with laser holes drilled all over it allowing water to leak all over the required area. If you want a short visit down south for some contrasting visuals and some very basic information, spend 1 minute, 53 seconds checking out Mr. “Lone Star” Irrigation.
