Pressure treated wood is treated with creosote and sometimes arsenic. I prefer not to have anything as poisonous as arsenic, even in trace amounts, in my garden area. I even hesitate to use pesticides. Cedar and redwood are both naturally water resistant without further treatment. I did try coating some of the pine boards, which were used in another trellis, for tomatos, with Thompsons Water Seal, but found it awkward to apply. So the boards have been left untreated for now.
Yes, I included the ruler so people could see everyone could see the lengths I used. Unfortunately, part of the mending plates were out of the frame, as there were a few other measurements written on it.
Here in the desert, the UV levels are much higher than that in some other places, which led to the net failure.
