They are all spaced FAR to close together for my mulch to work. I have to overhead water them as well so I'm kinda SOL for having to weed this year. The needles may actually work as mulch so I will likely go haul some back in to spread around and see.
I space at 6" apart and get at least 4" deep of mulch between each one, then mulch with a solid leaf of hay in front and back. That way they can come up in the spring and the mulch keeps the weeds mostly gone.
