This is what this area looked like last year, and here it is early this year as we were preparing it for the cor-ten steel beds, and what you see above is how it will stay from now on (hopefully) and in time, with a lot more green. We used cattle fencing (again) and arched them from one bed to another, and 3′ metal stakes to keep them in place. We got the fencing from a local farm supply store and they were so long that we had to rent a u-haul to transport it from there to our home. We put two 16′ long fence pieces in one bed, arched into the one parallel to it. It takes two people to get the fencing put in.
There will be 3 dwarf citrus trees in each bed, and we will train then to follow the arches. I can’t wait until we have this gorgeous walkway of green and citrus fruit; it will be so pretty! Also, the trunks of the trees are painted to prevent it from getting sunburned. We learned this last year and did the same (see here); this year we experimented with an organic approach. This might be my favorite part of the backyard so far!
