Tomato cage wrapped in lights! You could get very creative with this. Add faux green christmas tree garland, then add lights. You could use all sorts of different garland like snow garland, holly, pinecones etc. Buy a plastic outdoor urn/vase, fill it with dirt and stake it down into dirt. Instant, inexpensive Christmas tree for the front door!
Using a Trellis System - Your trellis system will need some kind of support: 4x4-inch posts or Studded T Posts driven into the ground are typical solutions. Lace heavy twine or wire and pattern string from top to bottom to support the crop.
