Sprinkler heads
I have a Toro brand system working well. All my bodies and heads are 570 XF modles. Some fixed and others rotate. I am adding a zone that I want to water 18 new Arborvitae trees set between the homes. These trees are 4' apart in a straight line covering an area about 80' long and 3' wide. So it's a "strip" of trees. I do not want to water the neighbors lawn or my driveway in excess! I have 2' feet on either side of the trees to set the heads. Q1: How many bodies will I need. Q2: what heads do I use.
Use drip irrigation if you don't want overthrow. A double line of drip tubing along each side of the row will do the trick.
Wet_boots, This is a good idea. I have very little experience so thanks. I saw "drip lines" but did not know if they could be installed "added" along with the other six rotor heads, that water the open lawn, on that zone.
Drip generally runs by itself, because it applies water more slowly than rotors or sprays.
