Dragon Fruit Trellis

I made a make-shift trellis for my pitaya plant. I used bamboo from my neighbor's yard; the only problems is that I don't know how to work with bamboo. I'm not sure how sound the structure is. I originally intended to just let the plant grow and drape over the pot. I still intend to let the plant hang over the container, but if a limb or two decide that they want to grow, now there is something to climb. I will add another inch of soil once the plant gets larger to help the pole be anchor more in the earth.
