Hi,

I originally have Hunter I20 rotor heads installed (the red dots on the picture). I now planted some more plants and I was told that if the rotor heads hit them directly, it’ll kill the trees. To keep the sprinkler heads where they are, I’m wondering what type of sprinkler head should I use instead of rotor heads and is it true that rotor heads will kill the trees? I have banana trees, Arborvitaes and Fir. Thanks.
