When going vertical the weight of the veggies has to be taken into consideration. Some are large and require additional support like cantaloupe.
The spacing on the trellis can also be a hindrance. If you cannot access both sides large fruits/veggies on the wrong side can be quite difficult to harvest since they may not fit through the spaces.
Don't get me wrong I am all for it. I have grown cantaloupe vertically. I had to pay close attention and carefully weave the vines through as well as make slings to support them. Beans are a fun one as they hang through the arch for easier picking. Cucumbers would also dangle through.
